swift3 - In Swift, what's the difference between calling UINavigationController() vs UINavigationController.init()?

Question

In Swift, what's the difference between calling UINavigation() vs UINavigation.init()? They both seem to return valid instance of UINavigationController.

Answer 1

UINavigationController() and UINavigationController.init() are the exact same thing. You can verify this by typing both into a Playground and then option-clicking on them. Both bring up the documentation for the same initializer.

The Swift convention is to use just the type name (without .init).
