Axiom Swift Performance

You're writing Swift code and Claude keeps suggesting Date() instead of Date.now, or hallucinating APIs that don't exist. This skill fixes that with modern idiom patterns, ownership conventions for noncopyable types, and complete Transferable reference for drag and drop. The tvOS section alone is worth it if you've ever wondered why your app compiles fine but the focus system breaks at runtime. The deep link debugging workflow cuts iteration time from minutes to seconds when testing navigation flows. Honestly, the anti-rationalization table at the end calling out CGFloat and Info.plist gotchas is the kind of thing you bookmark after getting burned once.
