How to get current user's playlist from Spotify - ios

Question

I am trying to implement Spotify integration with current user's playlist to display it in my tableview. I have integrated with login and access token everything works fine. I have gone through stack overflow link:- How to get the list of songs using Spotify in Swift3 iOS? but didn't work for me.
Then to get print for canonicalUsername as below, its showing nil value
SPTUser.requestCurrentUser(withAccessToken:(SPTAuth.defaultInstance().session.accessToken)!) { (error, data) in
guard let user = data as? SPTUser else { print("Couldn't cast as SPTUser"); return }
let userId = user.canonicalUsername
})
I have even tried this link Spotify iOS SDK Swift display all (!) playlists (20+) due to beginner may be it also didn't work for me. Is there any way to get Spotify's current user-id? How could I show the current user's playlist in my table view?

Just go through online tutorial in youtube :- https://www.youtube.com/watch?v=KLsP7oThgHU&t=1s for latest version in 2019.
Download full source code with Spotify Integration + search options + default Spotify url and fetch current user's playlist and play in our native iOS App

Based on your question the solution to get print canonicalUsername or current user's id try as below,
SPTUser.requestCurrentUser(withAccessToken: session.accessToken) { (error, data) in
guard let user = data as? SPTUser else { print("Couldn't cast as SPTUser"); return }
let userID = user.canonicalUserName
print(userID!)
}
Then to get current user's playlist and play in ur device, first call the SPT Delegate in your view controller like and then function call,
class PlayVC: UIViewController, SPTAudioStreamingDelegate, SPTAudioStreamingPlaybackDelegate {
func audioStreamingDidLogin(_ audioStreaming: SPTAudioStreamingController) {
let playListRequest = try! SPTPlaylistList.createRequestForGettingPlaylists(forUser: session.canonicalUsername, withAccessToken: session.accessToken)
Alamofire.request(playListRequest)
.response { response in
let list = try! SPTPlaylistList(from: response.data, with: response.response)
for playList in list.items {
if let playlist = playList as? SPTPartialPlaylist {
print( playlist.name! ) // playlist name
print( playlist.uri!) // playlist uri
// self.tableView.reloadData()// if u want to display playlist name and other stuffs like so..
SPTAudioStreamingController.sharedInstance().playSpotifyURI("\(playlist.uri!)", startingWith: 0, startingWithPosition: 10) { error in
if error != nil {
print("*** failed to play: \(error)")
return
}
}
}}}
}
}
