Thank you Brian i know another way of doing it now,you are the best

meher or brian, Can you further explain this concept using code examples. In one of my projects, I'm not using MainTabBarController as my rootViewController. I'm getting nil for mainTabBarController inside of didSelectRowAt. I've also tried instantiating a new instance MainTabBarController() to no avail. The podcast does play but there's no PlayerDetailsView presented to the screen. Brian - I was also checking out your Audible series about Protocols and Custom Delegation where you encountered a similar problem, but I can't quite translate it to fix this problem. Any help would be appreciated.

Awesome! That fixed the issue. However another problem arises now where the podcast does not play at all after selecting another podcast to listen to. Is this an issue with the existing player instance that is not de-initialized?

Odd, it works now!

I'm loving these videos and by far the best course purchase I've ever made!! I'm getting the same error as @SimonQ even after the check in the CMTime extension Am I missing something? import AVKit extension CMTime { func toDisplayString() -> String { let totalSeconds = Int(CMTimeGetSeconds(self)) let seconds = totalSeconds % 60 let minutes = totalSeconds / 60 let timeFormatString = String(format: "%02d:%02d", minutes, seconds) return timeFormatString } }

The solution is in the beginning of the next video! Thank you Brian!

Hi joker45 , In Option A , You are creating a new MainTabBarController which is not our application's rootViewController , So you will not see any change.

Sorry , I mean Why not in "EpisodesController" , where we initially created "PlayerDetailsView".

Hi Brain, I implemented the suggested code form the github link you provided. It is working to where I press the dismiss button and it minimizes the view, however there are a few problems that came with this. The first is that when the view minimizes, not only is it minimizing the playerDetailView but it also minimizing the mainTabBar view as-well so it shows a black screen and the tabBar on the bottom becomes an empty view with not TabBar buttons. Also when it minimizes, after a second it maximizes again without me pressing the view manually. I am comparing code and I have set up everything like yours so I'm not sure why I am getting this error.

Not sure if you saw my last message but I am still having some problems with calling the minimize and maximize functions from the tabBar into the PlayerDetailView controller. I have tried the solution above from github but instead of minimizing just the PlayerDetailView it minimizes all my views and leaves a black screen. I have tried this: guard let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene, let sceneDelegate = windowScene.delegate as? SceneDelegate else { return } let storyboard = UIStoryboard(name: "Main", bundle: nil) let controller = storyboard.instantiateViewController(withIdentifier: "MainTabBarController") as! TabBarController controller.selectedIndex = PlayerDetailController.selectedIndex ?? 0 sceneDelegate.window?.rootViewController = controller controller.maximizePlayerDetails() While it works, it is not as fluid and smooth as your minimize and maximize functions. I have downloaded your source code and it still shows that it is utilizing keyWindow but when I try to use that code in my dismissal button, it does nothing and the view doesn't minimize. I'm not sure if anyone else has had this problem but it has left me stuck for quite a while.

Also the above function for some reason refreshes all my viewcontrollers which leaves them changing to a weird lay out

Thank you , it helped . Good luck
