Update the frontend as the backend changes in real-time — Are you working with Firebase Realtime Database and wish your UI would just update when the backend does? This can be really helpful when changes can come from anywhere — i.e. in a multi-user app where one user performing an action may change another user’s data. …

Good discipline should be more of a concern than using a value type over a reference type — If you’ve been doing Swift Development for any length of time, I’m sure you’ve heard that it’s good practice to use a struct over a class by default.

Implementing a reusable programmatic UICollectionView — In this tutorial, we’ll implement MVC in a way that you may not be familiar with. We’ll create a reusable UICollectionView that’s implemented by its parent UIView and delegates item selection events to a UIViewController. This makes for a very small view controller when compared to the default way we…

Introduced at WWDC 2021, it will clean up your existing async code… with a little help — A lot of us have been waiting a long time for async/await syntax in Swift. First proposed in 2017, this API sets out to clean up the pyramid of doom that happens so often with async code. In the WWDC State of the Union, we were introduced to some amazing-looking…

Stub -> Fail -> Implement -> Test/Implement/Test Until Pass -> Refactor -> Test/Refactor/Test Until Pass -> Repeat — If you’re anything like me, you make a lot of assumptions when you develop software. Also, if you’re anything like me, you probably didn’t realize it until recently, or maybe you still don’t realize it. …
