+1. The auto yellow box clashes with our app’s password input styling that’s confusing to users.

iOS 12 recognise password textFields by isSecureTextEntry property and not just by textContentType property.

Way Around to bypass Auto-fill Strong Password Suggestion.

set isSecureTextEntry property to false.

self.passwordTextField.secureTextEntry = NO;

Add a UITextField Delegate Method and enable the isSecureTextEntry property.

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    if (textField == self.passwordTextField && !self.passwordTextField.secureTextEntry) {
        self.passwordTextField.secureTextEntry = YES;
    }
    
    return YES;
}

NOTE: - Do NOT Use shouldBeginEditing UITextField delegate method it Will Still show Auto-filling Suggestion. Do NOT Use textFieldDidChange UITextField delegate method it Will Auto-delete the first charachter as the it Will happen after the first charachter is displayed. And ‘secureTextEntry’ will empty the field.
