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. …
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. While this is true in many cases, and for good reason, it’s very easy for a struct to be just as unsafe…
Imagine you’re going on vacation. You know exactly where you’re going, how long you’re staying, and the weather pattern is very reliable. You’re super prepared for what’s to come, and you know exactly what you’ll need when you get there. It wouldn’t make sense to pack everything you own and…
ViewControllers? Very tinySo you’re sick of massive view controllers? Me too. Many architectures attempt to overcome this problem in a way that I view as extremely complex for the problem they’re trying to solve.
I favor simple architectures and simple solutions because they’re easy to understand, develop, and maintain. For this reason…
Say you’re making a singleton or static class to represent data and/or logic that will never change. In many cases, you can convert this logic to an enum and save yourself a bunch of hassle. An enum has much of the functionality of a class, but doesn’t require an instance…
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…
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…
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. …
In Swift, memory is handled for us pretty efficiently via ARC. Basically, reference objects (such as classes) hold a count for how many times they’re being referenced. When the count reaches 0, the item is marked for deallocation and removed from memory when the system needs the space.
If we…
Often when developing codebases, you probably want to model a situation with one of 2 possible outcomes. In Swift, this often means using optionals as the return type for a method. The idea is one of them will be nil, and the other will be non-nil.
What you may have…
