lasers and now this?! starting to sound like a very cool ctf hahah

β©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.

24.06.2025 14:52 β π 0 π 0 π¬ 0 π 0Here's an example app with a variety of views, all sporting AppKit-specific changes applied with a few lines each. See next for without changes.
In terms of not-so-visible modifications, I made the Count text selectable, moved the picker to the right edge, and enabled drag&drop image replacement.
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.
I usually include more screenshots, but these look basically the same on every platform just with different system fonts.

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).
It's borderless (i.e. no background) for max flexibility. The background in this example was whacked on by me (hence the mismatch between it and the Title field on Linux). A native bordered style will be supported eventually.

Screenshot of a code snippet showing a Qt app written in Swift
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 π! Swift's C++ interop is brilliant, the entire wrapper can be a target in the same Swift Package as the app itself!

Thank you to everyone who popped by during the stream π
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!

Any tips for avoiding frame drops when streaming+recording with OBS while compiling code would be greatly appreciated! I think I may have to give up on recording locally.

Join me on Twitch tonight at 10pm AEST (2pm CET, 5am PST) as I work on bringing SwiftCrossUI to Android! π€

I'll be playing around with a few different approaches including giving AndroidUIKit a go.
A recording is available on Twitch: www.twitch.tv/videos/24813...
It's watchable until around 50 minutes, which is around when I get the initial AppKitBackend web view prototype working. After that the lag and desync gets pretty bad.

Didn't manage to get it working everywhere (thank you Windows for all your strange failure modes...), but at least SwiftCrossUI has a WebView for macOS and iOS/tvOS!

I'll be explaining any SwiftCrossUI internals that we come across, and explaining my development process!
The build commands are existential because plugins can implement their own commands, and because the array of commands may be heterogenous. Commands are implemented as structs conforming to a protocol, rather than closures, because we need a notion of equality.
07.06.2025 16:01 β π 0 π 0 π¬ 0 π 0Used them today for both equality checks on an array of existentials, and round tripping said array to and from json for equality checks across runs. Iβm implementing a prototype plugin system for Swift Bundler and I need to check for equality of an array of build commands across runs for caching.

Got reminded of time travel debugging a few days ago and now I canβt stop thinking about it. I need it on macOS!
