Struggle with TextField delegate methods

Forums > Swift

Hello guys! I have a problem with textField delegate methods. I added two methods to my textField like below:

// MARK: - TextField Delegate extension ViewController: UITextFieldDelegate {

func textFieldDidEndEditing(_ textField: UITextField) {
    textField.text = ""
}

func textFieldShouldEndEditing(_ textField: UITextField) -> Bool {

    print("text filed should end editing")

    if textField.text?.isEmpty == true {
        textField.placeholder = "Type something"
        return false
    } else {
        return true
    }

}

func textFieldShouldReturn(_ textField: UITextField) -> Bool {

    print("should return called")
    return true
  }
}    

}

but in this code the method func textFieldShouldEndEditing(_ textField: UITextField) -> Bool doesn't called. But why ?

Hello, it is a bit late since you asked this question but I am worried isEmpty does not work because you may have defined your UITextField as optional. Please try to define text as text == "" or text.count == 0 to check if any of these work.
