I forgot to update my system-wide Swift Bundler to the latest version for Mac Catalyst support, and I was graced by a very informative error automatically generated by the wonderful swift-parsing package by @[email protected]

Found a great article about bypassing macOS's 2 macOS guest VM limit. Definitely worth a read! (even though I won't actually do what they discussed because it involves running a debug kernel)

Swift Bundler now supports targeting Mac Catalyst. Use the `--platform macCatalyst` command line option to try it out.
You can optionally set the interface idiom (often called Optimize for Mac) as seen in attached configuration.

Finally got around to updating the Swift Bundler docs to reflect the latest config file format. If platform-specific configuration overlays and custom builders (for e.g. pulling in CMake dependencies) sound interesting, check out the configuration article!

SwiftCrossUI now supports strict concurrency, thanks to Beberka’s recent PR adding all the necessary annotations!
The main thing that held back concurrency support for so long was MainActor not working with Gtk on Linux, but I fixed that issue recently by polling the main job queue with Gtk timers.

I'm working on making it easier to make platform-specific changes to SwiftCrossUI's underlying backend views. I've taken inspiration from swiftui-introspect.
This sort of flexibility will be super useful for more advanced user interfaces.

SwiftCrossUI now supports dynamic text styles!
They adapt to the current 'device class'. Sizes and weights were roughly taken from Apple's typography guidelines (with some extrapolation to fill in missing text styles on certain platforms).

I wanted to get a sence of what it means to use another UI framework in Swift for Linux and Windows. So I picked Qt6 and... hello world 😍! Swift's C++ interop is brilliant, the entire wrapper can be a target in the same Swift Package as the app itself!

SwiftCrossUI's AndroidBackend prototype now supports basic buttons, text and stacks. The example may not look like much, but we solved quite a few foundational challenges which will make future progress much faster!

Implicitly Opened Existentials (SE-0352) are the gift that keeps on giving. I love them so much. Their use cases are rare (in ‘well written’ code), but when you need them you really do need them!

Just published a basic landing page for SwiftCrossUI!

I've tested it with mobile, laptop and ultrawide screen sizes. But if you use your phone's browser in landscape then that's on you 😅

SwiftCrossUI's Music Player example app is starting to take form!
When I finally got around to testing today's improvements against Linux and Windows, almost* all of them just worked! And they adapted to look native on each platform 😉

Made a prototype of a Swift formal verification system a little while ago and never got around to sharing it!
Here's it finding a 'bug' in my questionable xkcd random implementation 😅

GitHub Copilot just "fixed" a bug by renaming a variable, and it gave a justification about how it fixed an underlying concurrency issue! 😆

Any suggestions for how to add hundreds of images to SwiftCrossUI's DocC documentation without exploding my GitHub repo?
My end goal is to add screenshots of each view/control under each backend so that people can get an idea of how things are expected to adapt across platforms.

26 failed CI runs later, SwiftCrossUI's automatically-generated documentation site contains documentation for each backend's platform-specific features (e.g. NSViewRepresentable) in addition to the existing documentation for the core SwiftCrossUI target.
