Answer 1

Transformed triazotan's answer into Swift3.

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

    if (range.location == textField.text?.characters.count && string == " ") {
        let noBreakSpace: Character = "\u{00a0}"
        textField.text = textField.text?.append(noBreakSpace)
        return false
    }
    return true
}

Answer 2

Here is Swift 3 from @Jack Song's answer

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..<newEnd, with: string)
        textField.text = newString.replacingOccurrences(of: " ", with: "\u{00a0}")
        return false;
    } else {
        return true;
    }
}
