No, there is no way to have a different image depending on orientation at launch. And that is not really the purpose of launch screen. It is intended to have something on screen, just to show app is launching. But not really done to convey information.

I have a UIView that i create with a XIB. I then want to add it on top of a parent, take up the whole screen but use the safe area i have set up constraints for in the xib.  I'm not sure I fully understand. Did you set constraint inside the UIView xib relative to safe area ? How did you do it ? I would do differently: don't have constraints inside the xib relative to Safe area Set constraints in code for UIView relative to Safe area by creating constraints programmatically.

First try to do an option-clean build folder. And restart Xcode after if that's not enough.

however if the size class changes during presentation Why would this happen ? Because user rotates the device ?

There are many other issues with the simulators ; In addition to the yellow background, I have alerts which frame is incompletely drawn, with fuzzy borders or whose texts is illisible… I filed 2 bug reports : Dec 15, 2020 at 6:01 PM – FB8941139. Xcode 12.3 display incomplete alerts In a view, I have an alert. The top left and right corners are now fuzzy: on about 30 pixels wide and 80 pixels high (but not uniformly on this whole rectangle), we don't see the alert background but the view that is behind; just as if those parts had ben snacked by some rodent… Dec 15, 2020 at 6:10 PM – FB8941145 Xcode simulator does not display alert correctly when removing App Xcode 12.3 (12C33) simulator iPhone 12 Pro Max - 14.3 iMac Catalina 10.15.7 When I delete the app from the iPhone, the top button "Edit home screen" is no more lisible (text black on black or transparent on black) I see you did the same (could you post FB reference, in case ?)

A code for what ? If I tell you, yes you can, just get it… Your question is absolutely meaningless. So please, avoid spamming the forum in the future. have a good day though.

Xcode 10.1 is not used a lot anymore… Maybe you should move to Xcode 11.3 at least, if you have enough RAM and disk space. Is it a recent Xcode installation ? How did you install Xcode ? Did you restart the Mac after installing ? You should try. Does it happen when you create a new project ? How much RAM have you ?

Hope that can help somehow: https ://www.hackingwithswift. com/example-code/media/how-to-record-user-videos-using-replaykit But it is not fully automatic, as you need to ask permission. And I don't think you can avoid this step.

You closed the thread by marking your answer as correct. So we all assume you are satisfied with it. Otherwise, the answer is : find the bug in your code… Have a good day.

I don't understand why you need it. You could do it programmatically. In the destination controllers, test for self.navigationController in viewDidload:         print(self.navigationController == nil ? "not nav" : "nav") If the destination is in a navigation stack, it is not nil. If it comes from a "pure" segue, it will be nil. However, if the originating VC is in a navigation stack, it will not be nil. To differentiate in that case, you would need to add a property in the destination var comesFromSegue : Bool = false and set it true in the prepare for segue. Note: you could encapsulate all this into a UIViewController subclass, overriding viewDidLoad var comesFromSegue : Bool? // Must be set in prepare; we assume here that there are only 2 cases: segue of nav override func viewDidLoad() {         super.viewDidLoad() if comesFromSegue == nil { // Then it was NOT set in a prepare, but segue we could be in a navigation stack anyway comesFromSegue = self.navigationController == nil	// Do we really come from a navigation ? Otherwise, we assume it is segue } // else { comesFromSegue = true } as set in prepare }

Did you test (at least on simulator) with 14.3 ? Have you an image in the launchScreen ? If so, check it is not too large (should be less than 1MB). I experienced problems with heavy images of serial MB. Have you a way to test in TestFlight ?

If you have plenty of space and BigSur, I recommend to download Xcode 12. But don't use 12.3 it is really buggy. Stay with 12.2 that you will find here: https://developer.apple.com/download/more/ Don't forget to close the thread once you're done and flying. Good luck.

Could you show the complete code with trim ? There was another thread with the same issue for trim. But I did the test and everything works OK here, both with 12.3 and 12.2 (on simulator).

I would first try 2 things : option clean build folder check in the Issue Navigator if you have some update to perform restart XCode possibly restart the Mac

Check the connection of the button to its IBOutlet and IBAction. Best would be to remove the connection anbd recreate. If not enough, please show the code where crash occurs ? If OK, don't forget to close the thread.
