The doc at the following link specifies using the textFieldShouldReturn

Answer 1

In Swift 4.2 and Xcode 10.1

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

    if textField == TF1 {
        textField.resignFirstResponder()//
        TF2.becomeFirstResponder()//TF2 will respond immediately after TF1 resign.
    } else if textField == TF2  {
        textField.resignFirstResponder()
        TF3.becomeFirstResponder()//TF3 will respond first
    } else if textField == TF3 {
        textField.resignFirstResponder()
    }
    return true
}
