First letter in UiTextField lowercase

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?

In Objective-C:

textField.autocapitalizationType = UITextAutocapitalizationTypeNone;

In Swift:

textField.autocapitalizationType = .none

You can turn off auto-capitalization with the .autocapitalizationType property in the UITextInputTraits protocol.

textfield.autocapitalizationType = UITextAutocapitalizationTypeNone;

For SwiftUI,

TextField("I want entered text to be all lowercase", text:$myText)
     .autocapitalization(.none)

You can set capitalization for TextField in the Text Input Traits of Text Field Attributes in XIB(interface Builder).

set setAutocapitalizationType:UITextAutocapitalizationTypeNone for UITextField.

In Swift:

textField.autocapitalizationType = UITextAutocapitalizationType.None

In Swift you can use the autocapitalizationType property:

yourTextField.autocapitalizationType = .none

To avoid completely there are three properties that we can set

textField.autocapitalizationType = .none;

and

textfield.autocorrectionType = .no;

and

textField.spellCheckingType = .no

Only setting .autocapitalizationType = .none; works but better we set other both the properties to avoid capitalising from autocorrection and spell checking.

Try this code:

textfieldname.autocapitalizationType = UITextAutocapitalizationTypeNone;

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
    }
