Hi! I'm developing a music app. I want to get the songs from different playlists to play a preview and later the user can buy them on iTunes. I'm getting the most played playlist via rss.applemarketingtools.com but I cant get the songs that contain the playlist. I tried to use Music Kit but I have to support iOS14 and MusicKit is not available. Anyone knows any api or someway to do it. Some apps like Instories got this. Thanks

Hi! I'm developing an app that adds music to photos and videos. I use AppleMusic as a source of the songs, the user can hear the preview of the song, buy it on iTunes, and use it. My question is I can use the preview of AppleMusic as an option if the user doesn't want to buy the song on iTunes? Would I be in breach of any apple policy? Thanks for the info!

Hi, I'm trying to save in the UserDefaults some identifiers for user-edited videos that we save on the Defaults. We save in this way: let data = try JSONEncoder().encode(myDesign) Defaults.setValue(data, forKey: myDesign.id) [...] allMyDesignsIds.append(myDesign.id) Defaults[.allUsersMyDesignsIds][userId] = allMyDesignsIds but we got an error when saving 10 elements, in the saving of the 8 element : 2023-08-01 17:44:08.656097+0200 AppName[12474:355884] [User Defaults] CFPrefsPlistSource<0x280d34480> (Domain: com.***.***.beta, User: kCFPreferencesCurrentUser, ByHost: No, Container: (null), Contents Need Refresh: Yes): Attempting to store >= 4194304 bytes of data in CFPreferences/NSUserDefaults on this platform is invalid.

I tried it with the same videos always and also it only happens in the first launch and the first savings of videos in the Defaults... Anyone knows what can be happening? We discard the size of the values, because after this bug we continues saving videos without any problem. Thanks!!
