Getting and Setting Cursor Position of UITextField and UITextView in Swift

Question

I\'ve been experimenting with UITextField and how to work with it\'s cursor position. I\'ve found a number of relation Objective-C answers, as in

Answer 1

in my case I had to use DispatchQueue:

func textViewDidBeginEditing(_ textView: UITextView) {

   DispatchQueue.main.async{
      textField.selectedTextRange = ...
   }
}

nothing else from this and other threads worked.

PS: I double checked which thread did textViewDidBeginEditing was running on, and it was main thread, as all UI should run on, so not sure why that little delay using main.asynch worked.
