How to count the number of characters in a text field iOS

Question

I want to count the number of characters when User want to validate his password :

I came out so far with this code, but seems doesn't work

@IBOutlet var password: UITextField!

 if (Password!.count < 6)
        {
/// Not acceptable
        }

Answer 1

for swift 5, I used this method and it is working fine

if password.text.count > 6 {
  //add scenario for this case here
}

Answer 2

How about

if password.text?.characters.count < 6 {
    ...
}
