THIS WEEK'S BLOG POST

Property Wrappers in Swift explained with code examples

I'm sure many of you are familiar with Property Wrappers, or at least, you've used built-in wrappers like @State or @Published. I've revisited this article and updated it to have a look at how they relate to Swift Macros and why Strict Concurrency might be the end of Property Wrappers.

WHAT I'M WORKING ON

Apple Design Workshop: Preparing for macOS Tahoe

I've been lucky enough to join the Apple workshop in Amsterdam to prepare RocketSim for macOS Tahoe. Last week, I've visited Amsterdam for three days and made great progress on RocketSim's UI.

Apart from updating the app icon, I've also spent time on revisiting existing user interface elements. A few custom components were ready to be replaced by system components and the new glass background truly makes the UI more part of the system:

If you have the chance to join any of Apple's workshops around the world, I'd highly recommend doing so. I've been able to sit down with an Apple Designer, who gave me dedicated feedback right away. I could even check-in multiple times during the workshop to revisit decisions. Altogether, it's a unique opportunity to set yourself up for success when the new OS updates become generally available.

At anytime, visit the Meet with Apple page to see if there's a workshop you can attend. Good luck!
