iOS 13 only calls the methods in SceneDelegate if the project is UIScene-based (the new default in Xcode 11).
If the project was created in Xcode 10 or earlier (or if you remove UIScenes manually) then iOS 13 will happily continue calling the methods in AppDelegate.
@kkarayannis I got it to work with iOS11/AppDelegate using the SessionManager. However, I notice that after just a few seconds of idleness the connection between my app and Spotify is lost. Question: Is there a way to re-establish the connection without having to go to the spotify application and come back every time? appRemote.connect() fails because apparently iOS suspends the Spotify application.
Hey. I'm trying to setup my app using the iOS quick start guide, implementing the methods in my view controller and not the App Delegate: when calling the appRemote.authorizeAndPlayURI(self.playURI) method, it switches to Spotify, attempts to authorise - but gives me a big fat X every time and then that's that.... is someone able to let me know what I might be missing please?
almost half way 2020 and this code does not work for iOS13 in the AppDelegate.swift, I am not using UIScene so it should work but nothing, every time I open the app it takes me to spotify to accept permission to use even though I already have, anyways I can't get tokens, refresh tokens, nothing I can't do anything to get past this. =/

Hey Luis, I could not manage to get it working with App Delegate, when down the Scene Delegate route and its working all good - are you able to try using scene?
Hi Sean, is it easy to convert to UIScene? I guess I'll have to do that 🤔.
Hi Sean, is it easy to convert to UIScene? I guess I'll have to do that 🤔.
It's doable! Basically called inititiateSession on session manager on a view controller, spotify returns an auth code to openURLContexts in SceneDelegate, then made a POST request to "https://accounts.spotify.com/api/token" with that auth code as a parameter along with spotify redirect url, client ID and secret, and that returns the access token.
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
guard let url = URLContexts.first?.url else {
return
}
print("scene openURLContexts called")
let parameters = appRemote.authorizationParameters(from: url);
if let code = parameters?["code"] {
UserDefaults.standard.set(code, forKey: "SpotifyAuthCode")
let baseURL = "https://accounts.spotify.com/api/token"
AF.request(baseURL, method: .post, parameters: ["grant_type": "authorization_code", "code": code, "redirect_uri": redirectUri, "client_id": Auth.spotifyClientID, "client_secret": Auth.spotifyClientSecret], encoding: URLEncoding.default, headers: nil).response { (response) in
if let data = response.data {
do {
let readableJSON = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as! [String: AnyObject]
let accessToken = readableJSON["access_token"] as! String
self.accessToken = accessToken
self.SpotifyConnectVC?.connectionEstablished()
} catch {
print(error)
}
} else {
self.SpotifyConnectVC?.showAlert(title: "Connection Failed", message: "Network connection was lost during Spotify authorisation, please try again.")
}
}
}
}

Hey Sean thanks, I got it to work, but one thing I don't understand is how to play tracks, for example I have a tableView and I select a song from one of the cells and I want this sdk to start playing the specific song ex. spotify:track:2Oehrcv4Kov0SuIgWyQY9e or spotify:track:6nDAs3PRe37fgqLfx51lBB as I'm clicking cells. Thanks in advance.

Thanks in advance.
Thats awesome you got it going nice work. I couldn't say for sure on how to get tracks playing mate as I didn't implement that in my app but, I'd imagine its something along the lines of using the appRemote. So when a user taps a cell, call something like:
func playTrack() {
let playerURI = "spotify:track:6nDAs3PRe37fgqLfx51lBB"
appRemote.playerAPI?.play(playerURI, asRadio: false, callback: { (result, error) in
// Handle Error
// Result will be YES if track plays successfully
})
}
... each time passing in the cell's text as the player URI
If you haven't already, implement SPTAppRemotePlayerStateDelegate and set yourself as delegate in order to be notified when the the track begins to play.
FYI: Xcode 11 will call func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any]) when you set the target back to iOS 12 or below, add var window: UIWindow? to your AppDelegate, and remove the UIApplicationSceneManifest from Info.plist.
Wow this is rediculously confusing.
can we stream crossfade 2 songs at a time?if there is away please support.
Is any one trying this feature or does Spotify prevent multiple instances of players?
I'm also curious why ios13 only works with SceneDelegate and not ApplicationDelegate. Thanks!
