Summary

If you're writing Swift code with Claude, you need this. It corrects the twelve most common outdated patterns Claude defaults to (Date(), CGFloat, DispatchQueue.main.async) and replaces them with modern idioms. It covers noncopyable types and ownership modifiers, the full Transferable protocol for drag and drop, debug deep links that cut iteration time by 60%, and tvOS development quirks that compile fine but fail at runtime. The conflict resolution section alone is worth it, it clearly separates when to use this versus concurrency or performance skills. Honest take: this reads like documentation written by someone who got burned by silent cross-app UTType failures and decided no one else should suffer the same fate.
