Great videos, I added following notification observer to detect when headphones are removed and podcast stops playing. To awakeFromNib() I added: NotificationCenter.default.addObserver(self, selector: #selector(audioRouteChanged), name: .AVAudioSessionRouteChange, object: nil) Then I added function to handle the audio route change: @objc func audioRouteChanged(note: Notification) { if let userInfo = note.userInfo { if let reason = userInfo[AVAudioSessionRouteChangeReasonKey] as? Int { if reason == AVAudioSessionRouteChangeReason.oldDeviceUnavailable.hashValue { // headphones plugged out -> continue playback or change the play/pause icon //player.play() playPauseButton.setImage(#imageLiteral(resourceName: "play"), for: .normal) miniPlayPauseButton.setImage(#imageLiteral(resourceName: "play"), for: .normal) } } } } And lastly I removed the observer: deinit { NotificationCenter.default.removeObserver(self) }

Hi Brian, I still not enrolled for a Apple developer account (I will do it soon) and so I run the app on the simulator. Is it normal I don't see the control center on it? When i drag down the control center i only see a blurred background with no control button..

Hi Brian, ur class is really helpful for me, thanks for ur fabulous class. The app is running successfully on the simulator, however, I faced a problem when trying to run the application on my IPhone8 plus. I got an error log when the app tried to parse the mp3 website. The error code is down below. ------------------------------------------------------ podUrl: https://feeds.soundcloud.com/stream/393187617-brian-hong-voong-storyboard-vs-code-speedrun.mp3 2018-04-16 11:30:27.261705-0600 Podcasts[8633:4436884] CredStore - performQuery - Error copying matching creds. Error=-25300, query={ class = inet; "m_Limit" = "m_LimitAll"; "r_Attributes" = 1; sync = syna; } --------------------------------------- It can grab the pod information, but it can't play .mp3 anymore. I also found the discussion from the stackOverFlow, https://stackoverflow.com/questions/46099940/credstore-perform-query-error?answertab=active#tab-top Plz help solve this problem, thanks lot. p.s. The link down below is my code, plz check it if u need it, thanks^^ https://github.com/HsinChungHan/Podcasts.git

Thank you sir.

Why does the code require .shared() for several of the code that we write? E.g. setupAudioSession and setupRemoteControl both have it in their blocks.

I am getting this error after enabling the capability for background audio: "Can't end BackgroundTask: no background task exists with identifier 1 (0x1), or it may have already been ended. Break in UIApplicationEndBackgroundTaskError() to debug." Does anybody have a solution for this?
