Pinning SwiftLint in CI when Homebrew won't let you
brew install swiftlint means whatever's stable today, and release-tag CI is most exposed to that drift. The fix pins to a portable binary, not a formula.

Development
Closing the test gaps: pure logic, an unreachable mock branch, and a Swift 6 flip
Extracting algorithms out of MusicKit's reach, a mock parameter that was silently ignored, and two tests that had been passing for the wrong reason all along.
Development
A segfault that wasn't a bug, and the API I finally deleted
A MusicKit service-layer cleanup where deleting dead methods crashed every test at once - and the fix was a clean build, not a debugger.
Development
Fixing History's load path, then catching myself over-commenting the fix
Three sequential fetches where one wasn't even needed up front, two quadratic recomputes, and a linter that exposed why I was really writing all those comments.
Development
The actor-isolation trap in "just move it off the main thread"
Synthesized Codable conformances inherit default MainActor isolation too, and async let has stricter demands than the task you already have.
Development
The whole-library scan I thought I'd already fixed
A pattern doesn't get fixed once. One more main-actor library scan hiding on a write path, and the batch API that was only wired in one direction.
Development
My Discover tab was empty because I asked Apple Music the wrong question
Library ids fed to catalog requests: two symptoms, one bug, a device-verified fix, and the 1,610-artist number that forced a redesign.
Development
When a filter set quietly becomes a feature
The Not Interested store only ever kept keys. Then it had to become a screen, and the model needed to carry its own description.
Development
The buttons weren't broken: the main thread was busy
118 green tests, a clean simulator pass, and dead buttons on a real phone. The bug was a @MainActor service doing synchronous work between awaits.
Development
Racing the main actor: when await is the race condition
@MainActor eliminates data races, not interleaving races. A generation token, a stale-failure guard, and a deterministic race test with no sleeps.
