Update: I tried the app on my phone through Test Flight and Splash Screen worked 100%. So must be problem with the OS Simulator program. Annoying, but sending straight to Test Flight seems to be a workaround if you're having this problem.

Once again Claude, you're awesome. That worked. Thanks a ton.

Thanks for the suggestion Claude. I tried the below, did not resolve the issue (error made me include "self" to start the "isEnabled" line): @objc func keyboardWillShow(notification: Notification) { print("keyboard is here") DispatchQueue.main.async { () -> Void in self.backButton.isEnabled = false } }I click the keyboards, "keyboard is here" prints to the console, but nothing happens to the back button. I'm using both default (qwerty) and decimal pads on keyboards.Without the "self" in there, the error is: Reference to property 'backButton' in closure requires explicit 'self.' to make capture semantics explicit
