Spotify SDK in Swift 3.0: how to know when a song ends

I'm building a personal app in Swift using the Spotify api, and one thing that it needs to do is to play another song once the song that was playing is over. I have the ids to the songs all ordered the way I want them to be, and I can play them successfully.

I just need to know if there's a way to tell when a song is at its end so I know when to start playing the next one or to do other things (I make a HTTP request every time a song ends for another reason).

Any suggestions or any resources you could point me to is incredibly helpful! Couldn't find an answer through google searches :(

Spotify API: Is there a way to determine when a song has finished playing?

This is a similar question that was posted but it was for javascript and it was never answered.

You can implement the SPTAudioStreamingPlaybackDelegate protocol, set the Spotify player's playbackDelegate property and implement didStopPlayingTrack. An example class would look something like this:

class MyClass: NSObject, SPTAudioStreamingPlaybackDelegate {
    var player = SPTAudioStreamingController.sharedInstance()


    func setup() {         // Whatever function does the setup.
        player?.playbackDelegate = self
    }

    func audioStreaming(_ audioStreaming: SPTAudioStreamingController!, didStopPlayingTrack trackUri: String!) {
        playNextSong()      // Or whatever else you wish to do here.
    }

    func playNextSong() {
        // ...
    }
}

(Note that the setup function could be anything--such as viewDidLoad if the object observing the player is a view controller rather than subclassing NSObject.)

Because didStopPlayingTrack is a delegate function, the Spotify SDK should manage when it gets called (more specifically, the player should call it on its delegate object)--you don't need to call it yourself as long as the player's delegate is set.
