## What it does

The skill walks an agent through wiring Apple Music into an iOS app. Catalog search runs on `MusicCatalogSearchRequest`, subscriptions are read from `MusicSubscription.current`, and playback goes through `ApplicationMusicPlayer` with its queue. Separate sections cover `MPNowPlayingInfoCenter` and `MPRemoteCommandCenter`, so the lock screen and remote controls get the metadata they need.

Setup comes first. The skill tells you to enable the MusicKit App Service for the explicit bundle ID, add `NSAppleMusicUsageDescription` to Info.plist, and set the `audio` background mode in `UIBackgroundModes`. Debugging code before those three are right wastes time, because nothing will authorize or play.

Inside you also get authorization via `MusicAuthorization.request()`, the Apple Music subscription offer sheet, a common-mistakes list and a review checklist. One catch worth knowing up front: catalog playback is gated on `canPlayCatalogContent`, so a user without a subscription gets no audio and your UI has to say so.
