Let me explain you.

When you call .isModel() function from any class it will check and return you bool value according.

First condition which means of presentingview controller is initialized then it will return true.

The code is only to check if any class is presented or not

Check if view controller is presented modally or pushed, ( using swift), but i dont know what for?
