MusicKit on iOS lets users play Apple Music and their local music
library natively from your apps and games. When a user provides
permission to their Apple Music account, your app can create

songs in the Apple Music catalog. If your app detects that the user is
not yet an Apple Music member, you can offer a trial from within your
app.
