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
}
