I want to detect if the user presses either just "return" key or "shift+return" key on the external keyboard to perform two different actions when the UITextView is the responder.

It works when UITextView is not responding by using UIKeyCommands

override var keyCommands: [UIKeyCommand]? {
        return [
            UIKeyCommand(input: "\r", modifierFlags: [], action: #selector(taskOne)),
            UIKeyCommand(input: "\r", modifierFlags: .shift, action: #selector(taskTwo)),
        ]
}

But when UITextView is being edited, it just adds a new line and doesn't detect these UIKeyCommands.

How can I solve this issue?

override press began function

override func pressesBegan(_ presses: Set<UIPress>, with event:  UIPressesEvent?) {
    guard let key = presses.first?.key else { return }
    
    switch key.keyCode {
    case .keyboardReturn:
        if key.modifierFlags == .shift {
            taskTwo()
        } else {
            // not the state for plus you want, pass it
            taskOne()
        }
        super.pressesBegan(presses, with: event)
        break
    default:
        super.pressesBegan(presses, with: event)
    }
}

and override func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool

for UITextViewDelegate
