The topic of iOS app architecture has evolved a long way from MVC. Unfortunately, the conversation becomes a frameworks and patterns war. The reality is: Rx is a framework; MVVM is a presentation pattern; and so on. Frameworks and patterns always come and go, but architectures are timeless. In this post, we will examine the Clean Architecture for building scalable apps in iOS.
The key to dependency injection is protocols. From there sprouts many variations, flavours, and techniques. Although this is yet another dependency injection™ blog post, I would like to share a pure Swift, battle-tested DI implementation with no outside dependencies or magic. It combines protocol extension and type erasure to give you a solid, flexible dependency injection.
Many techniques have been tried to tame the AppDelegate beast, usually ending up in moving code into private functions or extensions. However, the AppDelegate is much more complex than just moving code around. In this post, let’s examine a pluggable service technique with a few bonuses at the end.
There are hundreds of complex routing frameworks and libraries in iOS. Usually they’re overly complex to retrofit into an existing app or they completely bypass Storyboards. In this post, I’d like to offer a simple, native-like routing mechanism that leverages Storyboards like a boss to handle navigation.
Localization in Xcode is handled with NSLocalizedString, but it is such a verbose and legacy-like API. There’s a Swiftier way that still respects Xcode .xliff exports and comments.
Less code and less memory while performing the same task at hand is truly where the art comes in. In this post, I’d like to highlight some of the various pitfalls that lead to memory leaks, which inevitably result in crashes. I will also cover some tools and remedies to resolve these issues.
In this post, I’d like to show you how to create a Swift framework for iOS, watchOS, and tvOS and get them distributed via Carthage and CocoaPods. It’s a technique I use to share frameworks across all my apps and with the community.
