Hi, my app sees quite a lot of crashes (crash report below) and I have no clue how to debug the problem any further. The problems seems only to occur on macOS 11. Is there anyone als having this kind of problems? Are there fixes/workarounds? The source code of my app is open source - https://github.com/PDF-Archiver/PDF-Archiver if anyone would like to have a look into it.

Hi, I'm currently working on a little music app PoC. I want to search the albums in the Apple Music Catalog which will done via a MusicCatalogSearchRequest: let musicAuthorizationStatus = await MusicAuthorization.request() print(musicAuthorizationStatus) // Issue a catalog search request for albums matching search term. var searchRequest = MusicCatalogSearchRequest(term: searchTerm, types: [Album.self]) searchRequest.limit = 5 let searchResponse = try? await searchRequest.response() print(searchResponse?.albums) I would expect to get a valid search response but it is nil instead. This is the console log when no AppleID is configured on my test device: 2021-06-15 23:07:19.083194+0200 ShareFi[1519:727518] [Entitlements] MSVEntitlementUtilities - Process ShareFi PID[1519] - Group: com.apple.private.tcc.allow - Entitlement: kTCCServiceMediaLibrary - Entitled: NO - Error: (null) .authorized 2021-06-15 23:07:19.130446+0200 ShareFi[1519:727542] [DataRequesting] Failed retrieving MusicKit tokens: Error Domain=ICErrorDomain Code=-8102 "Failed to fetch user token."

Throwing .userTokenRequestFailed. 2021-06-15 23:07:19.131133+0200 ShareFi[1519:727542] [DataRequesting] Failed retrieving tokens for MusicDataRequest.Context(url: https://api.music.apple.com/v1/catalog/us/search?term=Earfood&types=albums&omit%5Bresource%5D=autos&limit=5). Error = .userTokenRequestFailed. When I use a sandbox account the error is still a .userTokenRequestFailed but the message says something like: Privacy terms must be accepted first. The Apple Music API seems to require a "Developer Token" but no "User Token" for search requests?! So my questions are: Is it possible to make MusicCatalogSearchRequests without having an AppleID configured? What resources can a user without a active Apple Music subscription interact with? Best regards :) Julian

Hi, is there a way to cache the data from the SwiftUI ArtworkImage across App starts and maybe even for offline use? Best regards Julian
