Shortest!

I think this is the shortest solution for secure entry as well as updating the picture of the button.

@IBAction func toggleSecureEntry(_ sender: UIButton) {

    textfieldPassword.isSecureTextEntry = !sender.isSelected
}

Assign the show/hide picture of the button according to the state selected /default , no need to create any variable or outlet.
