Hi, my name is Donny

Allowing other apps and webpages to link into your app with deeplinks is a really good way for you to make your app more flexible, and to ensure that users of your app can more easily share content with others by sharing direct links to your contents. To support deeplinking on iOS, you have two options available: Support deeplinking through custom URL schemes like maxine://workout/dw-1238-321-jdjd Support deeplinking through Universal Links which would look like this https://donnywals.com/maxine-app/workout/dw-1238-321-jdjd To add support for...

On iOS 26 we have lots of new ways to reimagine our UIs with Liquid Glass. This means that we can take a look at Apple’s built-in applications and find interesting applications of Liquid Glass that we can use to enhance our understanding of how Liquid Glass components can be built, and to understand what Apple considers to be good practice for Liquid Glass interfaces. In this post, we’re going to replicate a control that’s part of the new maps...

Liquid Glass is iOS 26’s new design language. This means that a lot of apps will be adopting a new UI philosophy that might require some significant changes to how you’re designing your app’s UI. If you’re not ready to adopt Liquid Glass just yet, Apple has provided you an escape hatch that should be usable until the next major iOS release. I recently explored updating my workout app Maxine to work well with Liquid Glass tab bars which you...

Swift 6.2 comes with several quality of life improvements for concurrency. One of these features is the ability to have actor-isolated conformances to protocols. Another feature is that your code will now run on the main actor by default. This does mean that sometimes, you’ll run into compiler errors. In this blog post, I’ll explore these errors, and how you can fix them when you do. Before we do, let’s briefly talk about actor-isolated protocol conformance to understand what this...

Swift 6.2 is available and it comes with several improvements to Swift Concurrency. One of these features is the @concurrent declaration that we can apply to nonisolated functions. In this post, you will learn a bit more about what @concurrent is, why it was added to the language, and when you should be using @concurrent. Before we dig into @concurrent itself, I’d like to provide a little bit of context by exploring another Swift 6.2 feature called nonisolated(nonsending) because without...

When your app has a tab bar and you recompile it using Xcode 26, you will automatically see that your tab bar has a new look and feel based on Liquid Glass. In this blog post, we’ll explore the new tab bar, and which new capabilities we’ve gained with the Liquid Glass redesign. By the end of this post you’ll have a much better sense of how Liquid Glass changes your app’s tab bar, and how you can configure the...
