Twister is an open-source solution to transfering playlists between Apple Music and Spotify. Twister is an iOS application and will soon be able to be found on the App Store.
To get this code to run you will need some API tokens from Apple and Spotify. I would recommend setting these variables somewhere in the code for easiest set up:
public var appleMusicDevKey = "nil"
public var spotifyClientId = "nil"
public var spotifyClientSecret = "nil"
public var spotifyRedirectId = "twister://callback"
To create an Apple Music developer token, I highly suggest using this link. I have found that other solutions do not produce accurate keys.
To get Spotify developer tokens follow this link. You will need to use a Spotify account, but this is quick, easy, and free!
