ios - How do you check current view controller class in Swift?

As far as I know, this would work in Objective-C:

self.window.rootViewController.class == myViewController

How can I check if the current view controller is a specific one?

To check the class in Swift, use "is" (as explained under "checking Type" in the chapter called Type Casting in the Swift Programming Guide)

if self.window.rootViewController is MyViewController {
    //do something if it's an instance of that class
}
