What does this code mean?

I had a long code using if statements to return based on if something was left empty. Then, my friend gave me this code:

func hasFilledPassword(text: String = "") -> Bool {
    let text = text
    return !(text == "")
}

what does the last part mean, please explain

Let me make parts of it

Part-1: text == "" means it will compare text with empty string. If it is empty then it will return true else false.

Part-2: ! will make true to false and vice versa.

so lets consider below scenario

  1. if your text has empty string then !(text == "") will become !(true) and it will return false.

  2. if your text has some string then !(text == "") will become !(false) and it will return true.
