When @MainActor and TaskGroup don't mix in Swift 6
The region-based isolation checker tells me to file a bug, and the unfashionable unstructured Task turns out to be the correct tool.
Development
Scheduling and smarter link-sharing for my Postiz cross-poster
Future scheduling, richer blurbs with thumbnails, and a which-URL picker, plus the wall-clock timezone bug and the import that copied the wrong column.

Building a MusicKit app when MusicKit won't run in the simulator
A protocol, a real service, and a mock that records its writes: making the simulator useful again, plus the worktree mishap and the newborn-target trap.
Development
