If you’ve ever thought Apple isn’t opinionated on app architecture, look again. App Intents has a type called AppDependencyManager built-in, which promotes injection of dependencies, and they even recommend using it in the main app target, setting it up in your App’s init. Buttons and Toggle can take an AppIntent. It’s almost like Apple built their own optional alternative to PointFree’s TCA. https://developer.apple.com/videos/play/wwdc2025/244/ https://developer.apple.com/videos/play/wwdc2025/275/ https://developer.apple.com/videos/play/wwdc2025/260/ https://developer.apple.com/videos/play/wwdc2025/281/

Apple has released the long-awaited Swift Playgrounds 4.6 update, or as it’s now known, Swift Playground! The release notes read as follows: This update includes a new document browser to easily create a new playground or find a recent one, and provides bug fixes and improved stability.

Interface changes The update also includes the new document browser demoed in June last year which is a big win for organising projects!...

The story so far Last year, I developed and released Medlied from my iPad using Swift Playgrounds. I cut out the Mac from my workflow completely, enjoyed live on-device previews that update in seconds, and I even got the privilege of doing a talk on my experience using Swift Playgrounds at Leeds Mobile! Unfortunately, this setup still has some holes which I ran into with my next project. First, Swift Playgrounds support for iOS 18 has failed to materialise....

In the last year, I’ve gone all-in on building apps using an iPad. I’ve never met another Playgrounds developer, and a lot of the community are surprised this is even possible! This post should clear up what is and isn’t possible when it comes to app development on iPad, and I hope to encourage others to give this a try too! I use my iPad hooked up to a keyboard, mouse, and monitor for most serious work, with both screens set to More Space....

Previews are a handy tool for getting a live look at all possible states of a view, and I often finding myself creating loads without thinking. Yet I find people often have trouble getting previews to work nicely. This is my attempt to break down my approach for those people. If you use TCA, which ties architecture very deeply to the view, my best advice is to look to their docs on the topic....
