Hey there, recently I changed the background color of my simulator by mistake. I typed in a ViewController: ProgressBar.backgroundColor = UIColor.yellow After that the background color of my simulator was yellow 😂. This means all the menus, Control Centre etc. This is a funny issue but now I want to change it to the default. Changing it the same way like above does not work unfortunately. Can someone help me?

Hey there,I want a macOS app to use a login item. I found this here, but it's a quite old document, difficult to understand, and not executable because of some errors.So do you know a suitable way to implement a login item? Preferably it should be installed itself when the user install the application.Thanks a lot!

Hey there, I created a video player like this one: https://developer.apple.com/documentation/avfoundation/media_playback_and_selection/creating_a_basic_video_player_ios_and_tvos But if the video file can not load (because of wrong url or missing internet connection) the player is just showing this loading-circle. So there is no information whether the video file can be loaded or not. Is there a way to check if a video file from the internet is available or not? Thanks!
