Apply max length to UITextField in swift.swift

extension MyViewController: UITextFieldDelegate {
    func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
        guard let text = textField.text else { return true }
        let newLength = text.characters.count + string.characters.count - range.length
        return newLength <= 30 // replace 30 for your max length value
    }
}

awesome! thanks!

thanks men

Thank you very much

Hi, if the maximum length I want to give it only to 2 textfields out of 5?

you need to check which textField is in the guard statement:

 func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
        guard textField == textFieldWithMaxLength, let text = textField.text else { return true }
        let newLength = text.characters.count + string.characters.count - range.length
        return newLength <= 30 // replace 30 for your max length value
   }
