I was recently interviewed by the lovely folks at Cushion¹ as part of their Talking Shop series about my life as a freelancer. You can read the full interview on their website but I’ve also put their questions and my answers below:

How did you get your start?

I started off strictly as a web developer, moving from agency to agency, not really enjoying what I was doing. At the same time, Apple had just released the iPhone and, shortly afterwards, the App Store. I thought iOS development looked fun, so I quit my job and started teaching myself how to do it.

Where did your first clients come from?

I had been freelancing as a web developer on the side for a number of years, so I had a few clients through that. Coincidentally, when I decided to freelance full-time, a friend from Twitter reached out and asked if I would be interested in appearing on The Gadget Show. For the segment the show wanted a freelance developer and a small company to build two separate apps, then see which was more popular. At the time, I had never built an app, so naturally, I said yes. It forced me to learn the ropes pretty quickly! I cobbled this app together and it ended up doing really well, scoring a feature from the App Store. From there, clients just kept coming.

What type of projects do you work on now?

Now there’s also the iPad, Apple Watch, Apple TV, so I work on a variety of projects — everything from little apps to find the best steak restaurant nearby to bigger ones for clients like L’Oreal and Glenfiddich.

What does your day-to-day look like?

At this point, I try to exclusively work from home. In the beginning, clients would insist on coming to their office. Those days would always be spent in meetings, talking about nothing, and not getting much done. Nowadays, I push for a video call in lieu of all that. I have clients I’ve never even spoken to, that I work with via email or Slack. They’re the best.

What has been the greatest challenge of kind of being a freelancer?

For me, it’s been time management. It’s so easy to procrastinate. Then you hit a deadline and realize that you’ve done nothing, you have to tell the client, but you don’t want to tell the client, so things get worse quickly. The biggest challenge for me was getting to a point where I can switch my work mode on and off.

What’s next for you?

A few years ago, I had my own app, an iPhone game called WallaBee. For about three and a half years, I focused on that and was extremely adamant about not hiring anyone else. In retrospect, some help might have made sense, but I was worried about being able to pay someone reliably month to month. It was a lot of fun, but eventually, I burned out and sold it.

Ultimately, I’d like to do something like that again, but at the moment, I enjoy freelancing.

It’s a constant battle between doing things that you want to do, but not earning any money, and doing the things that are less enjoyable, but make money.

I’m sure that statement resonates with a lot of freelancers.

When I was young and single, it was easy to spend twenty hours a day working on my pet project for no pay. The money earned mattered less because at the end of the day, it was just me. But when you have a family with mouths to feed and bills to pay, you find yourself taking less of those risks and opting for projects that provide a bit more security.

What advice would you give to someone just starting out?

Keep it simple. I spent a long time researching and reading up on various how-to-get-things-done philosophies, buying every to-do list manager there was. Now I just have a basic list, make my own invoices, and track everything else in Cushion. If you spend a fortune on loads of tools and to-do lists and all that, you end up spending more time tweaking your setup for productivity than actually being productive.

I’m currently in the process of writing an app which will store some information for each user on a server; the stored data should be available to the user on all of their devices. Usually there are two ways of dealing with this:

1. Build a user access system such that the user has to register to use the service. They’ll need to log in to the app (usually with email address and password) on each of their devices.

2. Use CloudKit to store all of the information in an Apple provided database.

The first option is overkill for this fairly simple app¹ and the second is too restrictive as it means I need to use Apple’s specific data modelling system. However, there is a third way which uses a bit of each of them…

When a user is logged in to an Apple account on their device², they are automatically signed into the iCloud system. With CloudKit, every app gets its own identifier based on both the CloudKit container and user account which doesn’t change. By retrieving this identifier, you can be 100% sure of the user that is using your app without knowing anything personal about them and without requiring them to manually log into your app.

To get the identifier, you first need to enable CloudKit within the iCloud section of the Capabilities panel in Xcode (which will require updating your provisioning profile). Then, it is a simple case of importing the CloudKit framework and using the following code:

let container = CKContainer.defaultContainer()
container.fetchUserRecordIDWithCompletionHandler { (recordID, error) in
    guard let recordID = recordID else {
        NSLog("Error: \(error")
        return
    }
    
    NSLog("Identifier: \(recordID.recordName)")    
}

The identifier returned will be 34 characters long and look something like this:

_e990774f93dd6625b11af6d40fceb310

Once you have that, you can then send it to your server to match it against whatever content you want to link to this particular user. Now whenever they use your app on any device with the same Apple account, they’ll have access to everything without the need for a manual account creation process and without having to hand over any personal information. The entire process is completely silent and is very secure as the identifier is generated from both the Apple account and your CloudKit container - it can’t be used by other apps nor can it be reverse-engineered to give you personal details of the user.

I find the code above a bit messy to be used multiple times throughout an application (not to mention the import CloudKit requirement) and so I’ve wrapped this up in a very basic Swift class that can be called as such:

AppleCloudIdentifier.fetch { (identifier, error) in
    guard let identifier = identifier else {
        NSLog("Error: \(error)")
        return
    }
    
    NSLog("Cloud identifier: \(identifier)")
}

I’ve named it AppleCloudIdentifier and the code is available on GitHub.

UPDATE [3rd May 2019]: I needed use of this in a recent project and so I’ve updated the code to make use of Swift 5 and the new Result type.

I was recently interviewed by Fast Company for an article they wrote about iOS features they’d like to see at WWDC this year. A couple of my suggestions were featured in the article but I thought I’d publish my full iOS 10 wishlist.

System Defaults

One of the things that I feel has been long missing from iOS is the ability to choose a default app for certain tasks such as email, web browser, phone, or notes. I would love to see a way for developers to make their app conform to some set of standards that would allow them to be selected as a default app. For example, Skype could conform to the “phone app” standard so when you tap a phone number in your mail app it’ll launch Skype and dial the number rather than using the Phone app. Similarly, email links could go to Polymail and web links to Chrome.

Siri API

I’ve long wanted a full API for Siri but so far there hasn’t even been a stepping stone. I imagine the first phase would go hand in hand with the System Defaults plan I outlined and that apps that adopt a certain standard would be able to show up in Siri. For example, if Spotify conformed to being a “music app” then saying “Hey Siri, Play C’est La Via by B*Witched” would start that track playing in Spotify rather than Music.

Control Center Buttons

When you swipe up from the bottom of the screen on iOS, you get Control Center which gives you quick access to certain features (like WiFi), controls (for music / video), and apps (Torch, Timer, etc). I’d like the ability to a) use 3D touch to get more options when using the features section (so I can choose a new WiFi network) and b) be able to choose the apps and features that show up in that area. I never need quick access to the calculator.

CarPlay

I’ve been using CarPlay for around a year now (via an after market Alpine iLX-700) and I absolutely love it. However, 3rd party apps are limited to a few selected audio apps like Spotify and Overcast which use a simple template that doesn’t work very well. I’d like to see support for any 3rd party app to use CarPlay and for it to use UIKit so that any interface can be displayed. I noticed in March that iOS 9.3 added a UIUserInterfaceIdiom for CarPlay so hopefully this is coming.

AirPlay

I have a number of AirPlay devices around the house and one of the things that frustrates me most is that I can’t use Siri to control them. I’d like to be able to say “Hey Siri, play my cooking playlist in the kitchen” and have it just work. I’ve been able to hack this functionality together via some Applescript and a fake HomeKit setup on my Mac called Homebridge but it’d be nice to have it built in natively. Also, iTunes on the Mac can AirPlay to multiple speakers at once whereas iOS can’t.

The 13th episode of The Divide podcast is now available in which we discuss video game consoles from our first tentative steps in the 8-bit era to the almost HD consoles of the modern day. We also discuss the Flic button, Day of the Tentacle, the Nvidia GTX 1080, Stellaris, and our predictions for WWDC.

A few days ago I wrote an article about getting my Flic button to work with HomeKit. Since then, I’ve had a few requests from people wondering how I was getting iTunes to work with HomeKit such that it could start a playlist on some AirPlay speakers. Today I’ve released a couple of HomeBridge plugins to NPM and I’ll detail how I’ve got my system working.

First of all, my entire setup is powered by the awesome Homebridge system which I’ve written about at great length. I found a plugin from Dan Budiac called homebridge-applescript which allowed you to run a line of applescript via a system of fake switches (so a different script could be called when the switch is turned on and off). This is great for simple one-liners (like “tell application iTunes to pause”) but I needed something a bit longer for dealing with AirPlay. I forked Dan’s project to create my own Homebridge plugin that would work with a path to an AppleScript file rather than a single line of AppleScript:

{
	"accessory": "ApplescriptFile",
	"name": "Kitchen Music",
	"on": "/Users/bendodson/Dropbox/Scripts/kitchenMusic.applescript",
	"off": "/Users/bendodson/Dropbox/Scripts/stopMusic.applescript"
}

This allowed me to then use my existing alarm clock script in order to make iTunes connect to my kitchen speakers and play a specific playlist¹ when my “kitchen speakers” switch is turned on and disconnect from AirPlay and pause iTunes when it is turned off.

This worked well but it has a few problems as the music is coming from a Mac in a different room; there is no way to change the volume, skip a track, or do a basic play / pause toggle² without going upstairs to do it manually on iTunes. After thinking about it for a little while, I was able to get the track skipping and play /pause done fairly easily. First of all, I use the following config:

{
    "accessory": "ApplescriptFile",
    "name": "Music Play Pause Control",
    "on": "/Users/bendodson/Dropbox/Scripts/playMusic.applescript",
    "off": "/Users/bendodson/Dropbox/Scripts/pauseMusic.applescript"
},
{
    "accessory": "ApplescriptFile",
    "name": "Music Track Control",
    "on": "/Users/bendodson/Dropbox/Scripts/nextTrack.applescript",
    "off": "/Users/bendodson/Dropbox/Scripts/previousTrack.applescript"
}

I won’t detail the AppleScript for each of these as they are fairly basic.

Next, I used the ‘Scenes’ feature of HomeKit to set up named scenes that related to each toggle. For example, “iTunes next track” is a scene that ensures the “Music Track Control” accessory is turned on whereas “iTunes previous track” ensures that accessory is off. The play / pause controls work in a similar way. Once activated, this meant I could say things like “Hey Siri, iTunes next track” or “Hey Siri, pause iTunes”.

Whilst scenes can be incredibly useful due to the ability to use any text you want, they can’t be used for something like volume where you want to use a specific amount³. Unfortunately HomeKit doesn’t have the concept of speakers so there isn’t a way to naturally create an accessory that deals with volume so I improvised and created a fake lightbulb that controlled an AppleScript via the brightness property; homebridge-applescript-file-lightbulb⁴.

{
    "accessory": "ApplescriptFileLightbulb",
    "name": "iTunes volume",
    "on": "",
    "off": "",
    "brightness": "/Users/bendodson/Dropbox/Scripts/volume.applescript"
}

The volume.applescript file looks like this:

on run argv
	set v to item 1 of argv
	activate application "iTunes"
	tell application "iTunes"
		set sound volume to v
	end tell
end run

With this in place, I can say “Hey Siri, set iTunes volume to 50%” and it will work. This is because lightbulbs have a brightness setting and Siri interprets “set [name] to [percentage]” as being “change the brightness of this device” just in this case we are hitting an AppleScript with our brightness value. This has been a fun little exercise in trying to hack HomeKit into what I want to use it for. I’m hopeful that iOS 10 will add native support for HomeKit speakers as then this could be done without reverting to AppleScript and I’d be able to stream from my iPhone via Siri but it’s pretty cool for the time being.

You can find both of my Homebridge plugins on NPM and GitHub.

Last year I worked on rebuilding the Great British Bee Count iPhone app for Friends of the Earth. Today, an updated version of the app has gone live to support this years count which runs from 19th May until 30th June 2016:

There are several updates including a redesigned bee picker, more details of the bees, and a list of plants suitable for attracting bees sponsored by Waitrose. The app is also now universal with support for both the iPhone and iPad¹.

You can check out the Great British Bee Count on the App Store (it’s free) or learn more about the bee cause.

When I started out as a web developer I was fascinated by APIs; the ability to hook into other data sources or update other applications from my own had huge potential that is finally being realised with the Internet of Things¹. It is now possible to write apps that interact with physical objects via such things as IFTTT or dedicated APIs for devices like the Philips Hue. I’ve personally been very interested in the HomeKit initiative from Apple although it hasn’t really taken off yet.

Whilst I have a lot of internet connected devices, I currently own just a single HomeKit-compatible device; an Elgato eve door & window that lets me ask Siri if my back door is currently open². Luckily there is the Homebridge project (which I’ve written about previously) that allows me to connect all of those together and use them as if they were native HomeKit devices.

Over the past few months, I’ve been dabbling with HomeKit scenes so that I can control groups of devices all at once like so:

Good Morning

• Turns on downstairs lights
• Starts playing my “morning” playlist in kitchen via AirPlay
• Disables security cameras

Good Night

• Turns off all lights (including bedside table lamp)
• Stops any playing music
• Enables security cameras

This has been working well but I frequently forget to use scenes as many of these things can be controlled in other ways. For example, I might turn off the downstairs lights with my Hue Dimmer Switch and then turn off the bedside table lamp via the Hue today widget which means I forget to activate the security cameras. The eventual solution I’ve come up with is a simple push button (from Flic) stuck under my bedside table that toggles between my Good Morning and Good Night scenes. In this article, I’ll tell you how I did it!

First of all, you are going to need a Flic. I did a lot of research on “smart buttons” and this one was far and away the best³. It’s small, has a changeable battery (that lasts 18 months), looks good, and it has an iOS SDK complete with background Bluetooth LE support so you can wake your app up even if it is inactive. The amount of code necessary to support Flic is ridiculously small; you can take a look at their iOS tutorial to see it in more detail but essentially you will be kicking your user to the Flic app in order to assign a button to the app. Once you’re back, it’s a simple case of activating a singleton and listening for a manager:didReceiveButtonDown request.

With the button tested and working, I set to work on adding HomeKit support to my app. This is relatively straightforward although you do need to create a dedicated provisioning profile in order to add the necessary entitlements to your project. Within a few minutes, I had a toggle in my app that would toggle between my Good Morning and Good Night scenes. That was when disaster struck; the HomeKit APIs do not work when your app is not in the foreground⁴.

This threw me for a little while until I decided that my app would simply have to connect directly to my mac and interface with the Homebridge software that was basically powering everything⁵. After a quick search, I found Homebridge-websocket, a plugin that basically adds a custom websocket server as a platform to HomeKit. You can create accessories (like a switch) within the websocket server and then you’ll get callbacks when they are turned on and off.

I planned to make use of this via a HomeKit property known as “triggers”. A trigger is basically a way for HomeKit to monitor a specific device for a specific value (i.e. when a switch is “on”). As soon as it sees that value, it will activate a chosen scene. I set this up by creating two new switches within Homebridge-websocket; ws_morning and ws_evening. I then set up two triggers within HomeKit; WebSocket Morning (which triggers the Good Morning scene when the ws_morning switch turns on) and WebSocket Evening (which triggers the Good Night scene when the ws_evening switch turns on). The only change I needed to make to my scenes was to ensure that both ws_morning and ws_evening are set to “off” when either is activated; this ensures that I can always turn them from “off” to “on” and thus cause the trigger.

The final step was to update my iOS app to talk to the websocket server instead of to Homebridge. I found a simple drop-in framework named Starscream which allowed me to connect to the server and send commands which led me to this code for the entire project:

import UIKit
import Starscream

let ipAddress = "192.168.1.100:4050"
let flicAppKey = "Your-Flic-App-Key"
let flicAppSecret = "Your-Flic-App-Secret"

class ViewController: UIViewController, SCLFlicButtonDelegate, SCLFlicManagerDelegate, WebSocketDelegate {

    let socket = WebSocket(url: NSURL(string: "ws://\(ipAddress)/")!)
    
    override func viewDidLoad() {
        super.viewDidLoad()
        socket.delegate = self
        SCLFlicManager.configureWithDelegate(self, defaultButtonDelegate: self, appID: flicAppKey, appSecret: flicAppSecret, backgroundExecution: true)
    }

    @IBAction func setupFlic(sender: AnyObject) {
        SCLFlicManager.sharedManager()?.grabFlicFromFlicAppWithCallbackUrlScheme("sceneControl")
    }
    
    @IBAction func toggle() {
        socket.connect()
    }
    

    // MARK: Flic Manager
    
    func flicManager(manager: SCLFlicManager, didGrabFlicButton button: SCLFlicButton?, withError error: NSError?) {
        if let error = error {
            NSLog("ERROR: \(error)")
        }
    }
    
    func flicButton(button: SCLFlicButton, didReceiveButtonDown queued: Bool, age: Int) {
        toggle()
    }
    
    
    // MARK: Websocket Delegate
    
    func websocketDidConnect(socket: WebSocket) {
        let defaults = NSUserDefaults.standardUserDefaults()
        let last = defaults.stringForKey("last_status")
        let name = last == "ws_morning" ? "ws_evening" : "ws_morning"
        let params = ["topic": "setValue", "payload": ["name": name, "characteristic": "On", "value": NSNumber(bool: true)]]
        let data = try! NSJSONSerialization.dataWithJSONObject(params, options: .PrettyPrinted)
        if let string = String(data: data, encoding: NSUTF8StringEncoding) {
            socket.writeString(string)
            socket.disconnect()
            defaults.setObject(name, forKey: "last_status")
            defaults.synchronize()
        }
    }
    
    func websocketDidDisconnect(socket: WebSocket, error: NSError?) {
    }
    
    func websocketDidReceiveData(socket: WebSocket, data: NSData) {
    }
    
    func websocketDidReceiveMessage(socket: WebSocket, text: String) {
    }
    
}

Note: this is just a personal project that I built as quickly as possible. By nature, it is a fairly dirty hack. You shouldn’t write professional apps like this.

With this code in place, I can now press my Flic button (stuck to the underside of my bedside table) and it will toggle between my Good Morning and Good Night scenes. This is the full process of what is going on:

• Press the Flic button
• Wakes up the iOS app (if terminated or backgrounded) and hits the toggle function
• App sends a websocket command to the Homebridge-websocket server
• Server turns on a fake switch
• HomeKit notices that the fake switch has been turned on so fires trigger to run appropriate scene
• Scene activates or deactivates various accessories and then switches the fake switch back off ensuring it is ready for next button press

This is a long way away from the process I’d envisioned (press button, wake up app, toggle scene with HomeKit API) but it has been a fun challenge finding a way to get it work. I now have a physical button that controls multiple aspects of my home with a single press - it’s pretty cool!

I’m currently in the process of switching from my Xbox One to a gaming PC¹ and have been spending a lot of time curating my Steam collection on my Mac. One thing I’ve noticed recently is that I often see games being updated but then have to go to their individual pages in order to view the release notes of what has changed (and that is if I even notice a game has been updated). What I really want is a single page that shows me all the patch notes in date order and sends me a notification when something updates.

A quick search found SteamNews, a website that aims to turn Steam Community pages into RSS feeds. However, a lot of games are missing and it doesn’t solve the problem of fetching the feeds for my account; I’d still need to go through and add them manually. I also don’t like relying on 3rd party services which I can’t install on my own server.

After a bit of exploring on the Steam pages, I found that most games have an RSS feed of their news page; this, combined with my publicly available profile page listing my owned games, has led me to write a basic PHP script to loop through my games, find the matching RSS feed, and then add it to my Feedbin account:

<?php

define('FEEDBIN_PASSWORD', 'your password here');
define('STEAM_ID', 'your steam id here i.e. bendodson');

There is a fair amount going on in this script² but the basic overview is:

1. Fetch a list of owned games from the public profile of the entered Steam ID. Most of the Steam pages are built with Javascript but this page fortunately has the entire library as JSON within the page. After a simple bit of extraction, I have a full list of every game owned.

2. Update a local text file³ – games.txt – with a list of games. I store each game as an ID followed by a hyphen and a flag to denote whether the game is unsubscribed, subscribed, or failed. For example, if I’m subscribed to the Elite: Dangerous game, the text file will contain 359320-1 as the game ID is 359320.

3. Just to be a pain, Steam doesn’t have a standard format for it’s RSS feeds. Whilst most of them contain the game ID, some of them don’t. The first step is to go with the usual URL and then if that fails we’ll use Goutte to manually scrape the news page and then the first news item in order to grab the correct RSS feed. For example, the game ID of Counter-Strike: Source is 240 so the script will first try http://steamcommunity.com/games/240/rss/ but when that fails it’ll crawl through some pages to discover the correct URL is http://steamcommunity.com/games/CSS/rss/ - there seems to be no logic as to which games have a shorthand name and which don’t and there isn’t an easy way to work out what the name would be.

4. Once I have a valid RSS feed, it is subscribed to via the Feedbin API. As an added bonus, I also tag the subscription “Steam Games” so they show up all together in my RSS reader of choice, Reeder:

5. Sometimes, the process might fail as in the case of Titan Quest which has no updates and thus no RSS feed. If that happens, the game is marked in the text file so that it can be safely ignored. In my own version of the script, I added Slack integration so I get a notification when a game fails so I check to see if it is a simple case of no feed or if my script has broken:

I have the script set up on a cron so if I purchase a new game the RSS feed for it should appear in Feedbin within the hour⁴.

One idea I dabbled with was fetching the feeds myself and building a single large RSS feed that I could subscribe to. There are a few issues there though:

• It would require me to constantly fetch each feed which could be huge if I own hundreds of games. I already pay for my RSS subscription service (Feedbin) so why add more complexity when they can do that for me?

• I’d be sacrificing some customisation. If I’m not interested in a specific game, I can simply remove the feed from Feedbin. My script doesn’t check subscriptions so it won’t try and re-add it.

• There is no benefit to one large RSS feed. If I was doing this as a commercial service (i.e. a hosted page where you enter your username and I give you a single feed) then it may make sense but I’m not interested in doing that⁵.

I’ve put all of the code on GitHub in case it is of interest to anyone.

A few years ago, I wrote a convoluted AppleScript that allowed me to use my Apple TV as an alarm clock. It worked by waking up iTunes, selecting a playlist, shuffling it, and then playing it via AirPlay. Unfortunately, it stopped working when iTunes 11 was released due to a number of changes to AppleScript support; there were also changes to OS X which prevented AppleScripts from launching via Calendar alerts.

Fast forward to today and I found myself needing this script again for a new project¹. After a bit of hacking around, I’ve managed to get the script fully updated for iTunes 12:

set AirplayDeviceName to "Kitchen"
set PlaylistName to "Morning"
set AirplayVolume to 100

activate application "iTunes"

tell application "System Events"
	tell application "iTunes"
		set visible of front browser window to true
		set the view of the front browser window to playlist PlaylistName
	end tell
end tell

tell application "System Events"
	tell process "iTunes" to if exists then
		click menu item "Songs" of menu "Shuffle" of menu item "Shuffle" of menu "Controls" of menu bar 1
		click menu item "On" of menu "Shuffle" of menu item "Shuffle" of menu "Controls" of menu bar 1
	end if
end tell

tell application "iTunes"
	set AirplayNames to (get name of AirPlay devices)
	set AirplayDevices to (get AirPlay devices)
	set AirplayToPlay to {}
	repeat with i from 1 to length of AirplayNames
		if item i of AirplayNames as string = AirplayDeviceName then set end of AirplayToPlay to item i of AirplayDevices
	end repeat
	set current AirPlay devices to AirplayToPlay
end tell

tell application "iTunes"
	play playlist PlaylistName
	set the sound volume to AirplayVolume
end tell

The script is significantly smaller thanks to some new AirPlay APIs within iTunes and I’ve updated it to allow for simple changing of volume. It should work in all versions of iTunes 11 and iTunes 12.

In order to get this working as an alarm, we have to jump through a number of hoops on OS X El Capitan. Firstly, we need to save our AppleScript as an application (after you’ve made any adjustments to your Airplay device name, playlist name, and the volume you want). You can do this by opening it within Script Editor and then choosing File > Export.

If you haven’t disabled the GateKeeper restrictions on your Mac, you will need to either Code Sign this app or grant an exception within the Security & Privacy settings after you have first tried to open it.

With the alarm exported, we now need to open up Automator and create a new Calendar Alarm. Find the Launch Application action and set that up to point to your newly exported alarm app. Finally, save this and you’ll find a new entry has appeared in your calendar; it will launch immediately thus starting off the iTunes alarm process. Simply copy and paste this alarm entry (or make it recurring) in order to set it to whatever times you want.

I’m going to continue playing around with different ways to launch the alarm but for now this works in much the same way as my old script did.

The full code (and previous version) is available on GitHub.
