My Question or Issue

Hi,

i am new to Swift an iOS development, so maybe this is an easy question, but i am really struggling with it. I am trying to connect to Spotify and play a song via appRemote. But when I try to connect my appRemote it is canceled with the following issue:

AppRemote: Connecting...

nw_socket_handle_socket_event [C2.1.1:1] Socket SO_ERROR [61: Connection refused]

nw_endpoint_flow_failed_with_error [C2.1.1 ::1.9095 in_progress socket-flow (satisfied (Path is satisfied), viable, interface: lo0)] already failing, returning

This is the Code from my ViewController:

class ViewController: UIViewController, UIApplicationDelegate, SPTSessionManagerDelegate, SPTAppRemoteDelegate, SPTAppRemotePlayerStateDelegate {

    override func viewDidLoad() {

        super.viewDidLoad()

        // Do any additional setup after loading the view.

    }

    let SpotifyClientID = "..."

    let SpotifyRedirectURL = URL(string: "test://callback")!

    lazy var configuration = SPTConfiguration(

        clientID: SpotifyClientID,

        redirectURL: SpotifyRedirectURL

    )

    

    lazy var sessionManager: SPTSessionManager = {

        print("sessionManager")

        let manager = SPTSessionManager(configuration: configuration, delegate: self)

        return manager

    }()




    lazy var appRemote: SPTAppRemote = {

        print("appRemote")

        let appRemote = SPTAppRemote(configuration: configuration, logLevel: .debug)

        appRemote.delegate = self

        return appRemote

    }()


    @IBAction func connectToSpotify(_ sender: UIButton) {

        let requestedScopes: SPTScope = [.appRemoteControl]

        self.sessionManager.initiateSession(with: requestedScopes, options: .default, campaign: nil)

    }

    func sessionManager(manager: SPTSessionManager, didInitiate session: SPTSession) {

        print("sessionManager didInitiate")

        self.appRemote.connectionParameters.accessToken = session.accessToken

        print("AccessToken: \(session.accessToken)")

        self.appRemote.connect()

    }

    

    func sessionManager(manager: SPTSessionManager, didFailWith error: Error) {

        print("sessionManager didFailWith")

        print(error)

    }

    
    func sessionManager(manager: SPTSessionManager, didRenew session: SPTSession) {

        print("sessionManager didRenew")

        print(session)

    }

    

    func appRemoteDidEstablishConnection(_ appRemote: SPTAppRemote) {

        print("connected")

        self.appRemote.playerAPI?.play("spotify:track:003vvx7Niy0yvhvHt4a68B", callback: { (result, error) in

           if let error = error {
                print(error.localizedDescription)
            }
        })

    }

...
}

 The code mainly was copied from the official example linked in the Spotify documentation but I tried to move the SessionManager from the AppDelegate to the ViewController. But when I do that I get the mentioned error. Can somebody help me? 🙂
