Swift Bundler can now automatically locate compatible Swift Android SDK + Swift toolchain pairs on the user's behalf. It also supports automatically installing and launching apps on Android devices and emulators. This is all in the as-of-yet unmerged Android support PR: https://github.com/moreSwift/swift-bundler/pull/136
If you'd like to try it out, follow the swift.org Swift Android getting started guide, then use the command in the screenshot to build SwiftCrossUI's CounterExample (on the android_support branch).

Is a fascinating and kind of surreal story and shows why validating anythings LLMs do is going to be very hard if what you are trying to do is well represented in the training set.
Running iOS 6 on iPad 1 is possible now!
SundanceInH2A rev4 brings iPad1,1 iOS 6.1.3 support
Make sure you read the README before using this tool
THIS IS POTENTIALLY DANGEROUS, IF THE WORLD CEASES TO EXIST AFTER RUNNING THIS - IT'S ALL YOUR FAULT
This demo of ElementaryUI from the pre-fosdem #swift meetup was very impressive. Looking forward to seeing where it can go.
Black-box (hardware ops) inverse CRC32C for Intel and NEON.

Prompted by a Pete Cawley post (1) and some recent comments on a 32-bit CRC base hash structure I tossed out a few years back (2)
