Musickit

This walks you through integrating Apple Music into iOS apps with MusicKit and MediaPlayer. You get catalog search, subscription checks, playback via ApplicationMusicPlayer, queue management, and the full Now Playing setup for Lock Screen controls. The guide covers authorization flows, remote command handling for AirPods and CarPlay, and all the entitlement configuration that will break silently if you skip it. Useful when you need more than just AVPlayer but don't want to reverse engineer Apple's sparse documentation. Targets Swift 6.3 and iOS 26+, so it assumes you're working with modern tooling. The common mistakes section alone will save you a rejected submission.
