You can also show/hide the status bar in an animation block, by putting animation code inside didSet property of variable that describes whether it should be shown or hidden. When you set a new value for the statusBarHidden Bool, this automatically triggers the animated updating of the status bar over the duration you have chosen.

/// Swift 3 syntax: 

var statusBarHidden: Bool = true {
    didSet {
        UIView.animate(withDuration: 0.5) { () -> Void in
            self.setNeedsStatusBarAppearanceUpdate()
        }
    }
}

override var prefersStatusBarHidden: Bool {
    return statusBarHidden
}

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)        
    statusBarHidden = false // show statusBar, animated, by triggering didSet block
}
