First letter in UiTextField lowercase

Question

How do you make it so that when you start typing on the keyboard after youve clicked on a UITextfield the first letter isn\'t a capital automatically?

Answer 1

this code will lowercase all the text field input when you type any thing in your targeted text Field

func textField(_ textFieldToChange: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
         //just change this charectar username  it's a text field
        if textFieldToChange == username {
            let characterSetNotAllowed = CharacterSet.whitespaces
            if let _ = string.rangeOfCharacter(from:NSCharacterSet.uppercaseLetters) {
                return false
            }
            if let _ = string.rangeOfCharacter(from: characterSetNotAllowed, options: .caseInsensitive) {
                return false
            } else {
                return true
            }
        }
        return true
    }
