Description: MusicKit makes it easy to integrate Apple Music into your app. Explore the Swift-based framework: We’ll take you through the basic process of using MusicKit — including how to find, request, and play content — and show you how you can incorporate music subscription workflows into your app if someone hasn’t yet signed up to Apple Music.

• MusicKit allows access to Apple Music API to search for content
• It also allows for playback in third party apps (user needs to be subscribed)
• Music items: Album with attributes, relationships and associations
• Use album.with([.artists, .tracks, .relationAlbums]) for fetching relationships
• All calls are using Swift concurrency, so try await needed on call site
• Playback integrates with system, so media controls in lock screen work for example
• Requests done via MusicCatalogResourceRequest<Album>(matching:equalTo:)
• Then just call try await request.response() on the request object
• Contributor comment: The networking structure here is interesting, maybe a new platform best practice!?
• User consent is needed to access music listening history & music library (separately)
• Access is given once per device & per app, dialog has “yes” / “no” options
• As always, a usage description must be provided in Info.plist file
• Use MusicAuthorization.request() (async method) to get access in MusicKit
• API token for Apple Music API is automated by Xcode, just check the box in Connect
• 3 information to check regarding subscription capabilities:
  • can play catalog content, has cloud library enabled & can become subscriber

• MusicSubscription.subscriptionUpdates informs app when user subscribes
• Two players available, SystemMusicPlayer integrates with system more, ApplicationMusicPlayer allows for more customization for the app like playback queue
• Apple Music free trial can be started right within third party apps via system sheet
• New Affiliate program to get bonus if users subscribe via 3rd party app
• Class supports album customization, named MusicSubscriptionOffer (.Options)
• Possible use cases: background music in games, music during workouts, social media
