I love you. Helped me so much! Great tutorial dude, keep it up. I couldn't figure out how to tell the ViewController something from outside of it but this solved it.

Good explanation of the different methods to use.

@19:09: This is not correct, because `self` is not the observer, the closure is.
So you should add a reference to what's returned by addObserver(forName...), a NSObjectProtocal object, and removeObserver() this object.

Great tutorial but once When you have a tab bar controller with 2 VC's only the initial view controller is loaded into memory at beginning , So the second VC is nil until we click and load it into memory which essentially If we run the app and try to refresh before we click on the second VC it won't work .. Any suggestions on best practice to load all VC's first?
