Only uppercased UITextField Swift

I want to force UITextField input to uppercased text. This is what I did:

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
    let nsString = textField.text as NSString?
    let newString = nsString?.replacingCharacters(in: range, with: string)
    textField.text = newString?.uppercased()
    return false
}

Is there any way to force uppercase UITextField without using replacingCharacterInRange of NSString?

I found it!

I just added a target to my TextField of type UIControlEvents.editingChanged And in the selector I did: textField.text = textField.text?.uppercased() Here is the code:

myTextField.addTarget(self, action: #selector(myTextFieldTextChanged), for: UIControlEvents.editingChanged)

func myTextFieldTextChanged (textField: UITextField) {
    textField.text =  textField.text?.uppercased()
}

This is exactly what I was looking for. Thanks every one!

It's very easy, just do this

self.yourTexField.autocapitalizationType = UITextAutocapitalizationType.AllCharacters;
