Answer 1

Try this code. Hope you will get what to do.

func updateSaveButtonState() {
    let text = titleTextField.text ?? ""
    saveButton.isEnabled = !text.isEmpty
}


@IBAction func textEditingChanged(_ sender: UITextField) {
    updateSaveButtonState()
}

@IBAction func returnPressed(_ sender: UITextField) {
    titleTextField.resignFirstResponder()
}
