Complete solution for iOS 11 and Swift 4, giving you full control from your program.

var statusBarHidden : Bool?

override var prefersStatusBarHidden: Bool {
    get {
        if let status = statusBarHidden { return status } else { return false }
    }
    set(status) {
        statusBarHidden = status
        setNeedsStatusBarAppearanceUpdate()
    }
}

Now you can simply show or hide the status bar by setting the property from your code. I tested it like this:

@IBAction func Show(_ sender: Any) {
    prefersStatusBarHidden = false
}

@IBAction func Hide(_ sender: Any) {
    prefersStatusBarHidden = true
}

Works like a charm.
