You can use

override public func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    // hide status bar
    dispatch_async(dispatch_get_main_queue(), {
        if let window = UIApplication.sharedApplication().keyWindow {
            window.windowLevel = UIWindowLevelStatusBar + 1
        }
    })

}

override public func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(animated)
    // Show status bar
    dispatch_async(dispatch_get_main_queue(), {
        if let window = UIApplication.sharedApplication().keyWindow {
            window.windowLevel = UIWindowLevelNormal
        }
    })

}
