What is the error ?I wanted to use the method?

Question

Swift

What is the error I wanted to use the method for the abundance of the statusBar It throws an error I don’t understand why?

Answer 1

The error is that method does not override any method from its superclass, obviously.
Learn to read compiler output - useful!

Answer 2

In iOS 10 preferredStatusBarStyle is a property, not a method. Should be written like this

override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
}
