Two other ways I can think of doing this are:

1. Make the new init a designated initializer, and make the old init (that always passesNavigationBar.self to super) a convenience init.
2. Give the navigationbarClass parameter a default value ofNavigationBar.self

If you prefer either of those, I'll update my PR.

Hey@phlippieb , thank you for your contribution. I would go with your first option. Which I guess what you meant should look like this, but with 2-spaced indention just like other parts of the file:

publicoverrideconvenienceinit(rootViewController:UIViewController){self.init(rootViewController: rootViewController, navigationBarClass:NavigationBar.self)}publicinit(rootViewController:UIViewController, navigationBarClass:AnyClass?){  super.init(navigationBarClass: navigationBarClass, toolbarClass:nil)setViewControllers([rootViewController], animated:false)}

If@DanielDahan approves either option, You may remove the commit rebase development branch again and reapply changes and do one clean commit. To be honest, I am not sure about the second option.
