Configuring a custom navigation bar class in the UINavigationController

I have a custom navigationBar:

class Name_UINavigationBar: UINavigationBar {
    // code
}

and I want to programmatically configure it on a navigation controller. So I tried:

var navController : UINavigationController = UINavigationController(
            navigationBarClass: object_getClass(Name_UINavigationBar),
            toolbarClass: nil)
// code

But he collapsed, saying:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', 
    reason: 'MyProject.Name_UINavigationBar is not a subclass of UINavigationBar'

Try it.

let navController = UINavigationController(navigationBarClass: YourNavigationBar.self, toolbarClass: nil)

I ran into the same error and was able to get it working again.

There is no supported way in Swift to get an object class. Your problem is almost certainly related to a method object_getClassthat I believe is no longer supported with Beta 5.
