All the answers above are awesome and very indicative! Especially big thanks to meaning-matters's answer below. Here's a tested Swift 2.0 version. Remember to assign the delegate of the UITextField to your ViewController! Happy coding.

func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool {

    if (textField == self.desiredTextField) {
        var oldString = textField.text!
        let newRange = oldString.startIndex.advancedBy(range.location)..

And here is Swift 3!

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
    if (textField == self.textfield) {
        let oldString = textField.text!
        let newStart = oldString.index(oldString.startIndex, offsetBy: range.location)
        let newEnd = oldString.index(oldString.startIndex, offsetBy: range.location + range.length)
        let newString = oldString.replacingCharacters(in: newStart..
