I have a UITextField in my iPhone app. I know how to make the text field select all of its text, but how can change the selection? Say I wanted to select the last 5 characters, or a specific range of characters, is that possible? if not, can I move the lines marking the beginning and end of the selection, as if the user is dragging them?

here is how I selecte file name Panda from Panda.txt

func textFieldDidBeginEditing(_ textField: UITextField) {
    // if textField.text is `Panda.txt`, offset will be 3
    let offset = String(textField.text!.split(separator: ".").last!).length
    let from = textField.position(from: textField.beginningOfDocument, offset: 0)
    let to = textField.position(from: textField.beginningOfDocument,
                                offset:textField.text!.length - (offset+1) )
    //now `Panda` will be selected
    textField.selectedTextRange = textField.textRange(from: from!, to: to!)
}
