Buddybuild: build, deploy and gather feedback for your apps with one seamless, simple solution.
Buddybuild is the simplest and fastest way to automate building, deploying and gathering actionable feedback from your testers. A 'git push' kicks off a build and instantly deploys to testers. With a simple screenshot, you'll receive tester feedback and diagnostic details to help resolve issues. Stop cobbling together and maintaining disparate build, deployment, crash reporting, and feedback systems. Focus on what matters most: creating awesome apps.
Swift 2.2 Release Process
Apple published some details about how the release of Swift 2.2 is going to go down, and it's happening soon. There's going to be an initial branch in just a couple of days which will head towards a release date somewhere between March and May. After that, it's all about Swift 3.0 which I'd expect to see betas of around June time at WWDC.
Will you ever be able to write Android apps in Swift? I can't imagine this becoming super popular (just like I don't think that iOS apps written in Java would become popular if it were possible). However it's an interesting experiment and there may be some value to being able to share bits of model code between platforms.
Xcode's refactoring support has always been a bit of a joke, but if you've switched to Swift in the last 18 months then the joke is over because it simply doesn't work at all. I'm sure it's being worked on, and I'm sure it'll be great when it comes, but until then you might want to check out this plugin from John Holdsworth. It only supports renaming, but its better than nothing.
Playgrounds are great, but what if the code is already inside your app? This plugin from Shengjia Wang allows you to select some code in Xcode and quickly run it. The biggest limitation is (fairly obviously) that you can't make reference to anything outside the scope of what's selected, but the same limitation exists with copying some code into a playground, so you're not really any worse off.
NSNotificationCenter is Probably an Anti-Pattern
In response to the NSNotificationCenter release notes I linked in the last issue there have been several articles published this week discussing the observer pattern. Jared Sinclair advocates against the use of notifications in almost all circumstances. Then, Ben Sandofsky wrote on a similar subject in his article discussing Delegates vs Observers and Jared finishes it off by wondering what a first party Swift implementation of KVO might look like.
RE: Why Swift guard Should be Avoided
Another follow up from last week. In this article David Owens digs further into the guard argument. However the main point of the post is that there's no right answer to this and that you certainly shouldn't be aiming for any kind of generic "you must do this to be correct".
Typed, yet Flexible Table View Controller
Arkadiusz Holko with a look at various approaches on how to architect your table view controllers and cells. He ends up with an approach where the view controller with no fragile switch statements, which is type safe and in fact doesn't need to be modified at all in order to add new cells. Interesting approach.
Exploring Swift Array's Implementation
It's just a few pointers... right? 😎
Jedi Principles of UI Animation
Kit Oliynyk puts down some guidelines for modern animation on mobile devices. Most of the examples here feel like motion graphics mockups rather than examples from real apps and so they feel a bit over the top in most cases, but the article brings up some great points so make sure you read the words, and don't just skim over the pretty pictures. 😇

Fixing the App Store purchasing problem
Rene Ritchie imagines a world where any iOS app can be bought from any device (including the web). I like the idea but my gut feeling is Apple have held back from this due to the potential confusion of purchasing apps for devices that the user doesn't own. Android (which has had this feature for a long time) handles this by having all owned devices registered with the purchasing account so it knows which apps are compatible. I can't see any good reason Apple wouldn't be able to do something similar though.

Unofficial Apple Icon Design Awards
Brutal, but funny. 😆
Did you all make millions over the last couple of weeks? Apple just released some stats which said that over $1.1 billion was spent on the App Store between the 21st December and the 3rd January.
This is an astounding amount of money but as many people are speculating, likely comes from quite a small percentage of the available apps on the store, and mainly from in-app purchases. However, it does prove that people are willing to spend money on the store, which can only be a good thing for the platform.
On a different subject, I must make an apology for last week's issue. When I linked to PMKVObserver I made a mistake and it should have been attributed to Kevin Ballard who is the correct author of it! My apologies, I'm really not sure how that happened.Dave Verwer
