It’s common for developers to leverage protocols as a means to model and abstract dependencies. Usually this works perfectly well and there’s really no reason to try and pretend that there’s any issue with this approach that warrants an immediate switch to something else. However, protocols are not the only way that we can model […]

A while ago I’ve published a post that explains how you can use AsyncStream to build your own asynchronous sequences in Swift Concurrency. Since writing that post, a new approach to creating AsyncStream objects has been introduced to allow for more convenience stream building. In this post, I’ll expand on what we’ve already covered in […]

When you work with CI, you’ll know how frustrating it can be when a CI server has versions of Xcode or other tools installed than the tools that you’re using. Especially major Xcode releases can be problematic. If your CI doesn’t have the same new versions available while your project uses recently released features which […]

The long awaited iOS 17.4 and iPadOS 17.4 have just been released which means that we could slowly but surely start seeing alternative app stores to appear if you’re an EU iOS user. Alongside the 17.4 releases Apple has made Xcode 15.3 and Swift 5.10 available. There’s not a huge number of proposals included in […]

When you’re decoding JSON, you’ll run into situations where you’ll have to decode dates every once in a while. Most commonly you’ll probably be dealing with dates that conform to the ISO-8601 standard but there’s also a good chance that you’ll have to deal with different date formats. In this post, we’ll take a look […]

When Swift 2.0 added the throws keyword to the language, folks were somewhat divided on its usefulness. Some people preferred designing their APIs with an (at the time) unofficial implementation of the Result type because that worked with both regular and callback based functions. However, the language feature got adopted and a new complaint came […]

Swift’s current concurrency model leverages tasks to encapsulate the asynchronous work that you’d like to perform. I wrote about the different kinds of tasks we have in Swift in the past. You can take a look at that post here. In this post, I’d like to explore the rules that Swift applies when it determines […]

With iOS 17, we’ve gained a new way to provide observable data to our SwiftUI views. Until iOS 17, we’d use either an ObservableObject with @StateObject, @ObservedObject, or @EnvironmentObject whenever we had a reference type that we wanted to observe in one of our SwiftUI views. For lots of apps this worked absolutely fine, but […]

As we work on projects, we usually add more code than we remove. At least that’s how things are at the beginning of our project. While our project grows, the needs of the codebase change, and we start refactoring things. One thing that’s often quite hard to get exactly right when coding is the kinds […]

Having a local git repository is a smart thing to do. It’s even smarter to push your local git repositories up to a remote server so that you can collaborate with others, clone your repository on a separate machine, or have a backup of your code in case you’re replacing your current development machine with […]
