Accessing the MPMusicPlayerController.systemMusicPlayer() (code below) works for getting track info for what's playing in the Apple Music app, but is there a way we can access information of the current song playing in the Spotify app?
This code posted in this answer I need to know how to get information about which player is currently streaming (player, spotify, napster...) uses MPNowPlayingInfoCenter which is nil whether using Apple Music or Spotify etc.
let player = MPMusicPlayerController.systemMusicPlayer()
@IBAction func getMusicButton(_ sender: UIButton) {
if let mediaItem = player.nowPlayingItem {
let title: String = mediaItem.value(forProperty: MPMediaItemPropertyTitle) as! String
let albumTitle: String = mediaItem.value(forProperty: MPMediaItemPropertyAlbumTitle) as! String
let artist: String = mediaItem.value(forProperty: MPMediaItemPropertyArtist) as! String
print("\(title) on \(albumTitle) by \(artist)")
}
}
The Apple Documentation states there are two types of music player:
- An application music player plays music locally within your app. It is not aware of the Music app’s now-playing item, nor does it
affect the Music app’s state. There are two application music players:
applicationMusicPlayer and applicationQueuePlayer. The application
queue player provides greater control over the contents of the queue
and is the preferred player.
- The system music player employs the built-in Music app on your behalf. On instantiation, it takes on the current Music app state,
such as the identification of the now-playing item. If a user switches
away from your app while music is playing, that music continues to
play. The Music app then has your music player’s most recently-set
repeat mode, shuffle mode, playback state, and now-playing item.
The first is only within your app and the second is the Apple Music app, since you can't reach out of your app's sandbox in a normal app this is not possible in App Store apps.
If however you still want to create your idea you can develop this on a jailbroken device. This github project has an easy example of how to get the current playing song in a jailbreak tweak. If you want to try it, this is an excellent, be it a bit old, still accurate tutorial on how to get started developing tweaks.
Update
I just ran into this Spotify SDK that will let users login and play the users Spotify music. This way the music stream will be inside your app and you have access to all info in the applicationMusicPlayer. The downside is that this will be a lot more work to set up than just getting the information about Spotify's playing track and the user will have to play his music from your app instead of the Spotify app.
