Hi. I am having this issue in our app. It happens only in IOS 14. And I am unable to catch this crash in debug mode because app is crashing only in when we download the app from TestFlight..

About this problem I write a post in stack overflow you can also take a look for details:
https://stackoverflow.com/questions/64045660/app-crashes-after-keyboard-shows-only-in-testflight-release-and-ios-14

We are trying to login we write informations to textfields keyboard is open and then we pressing the login button screen seems like freezing and some seconds after keyboard field become black and then app is crashing. When we press login app request to api and shows loading after response received loading closing and going to next screen with rootViewController.

Code:
self.resignTextField(item: self.view)
self.loginButton.isUserInteractionEnabled = false
DispatchQueue.main.asyncAfter(deadline: .now() + 0.2) { [weak self] in
self?.loginButton.isUserInteractionEnabled = true
self?.viewModel.login(username: username, password: password)
}

What is the problem. Any body faced with this error before? Please help.

It happens every time.. Now I catch this problem in debug. When this happens?: "When keyboard is shows and then Loading popup show called which works with adding a view to ViewController's View.. Only happens in ios14
Issue Running 'AppName' popup show up and this message was inside:

Code Block DetailsThe app “AppName” on iPhone’u quit unexpectedly.
Domain: IDEDebugSessionErrorDomain
Code: 4
Failure Reason: Message from debugger: Terminated due to memory issue

Xcode 12.0 (17219)

And last log was:
