NavigationController and Data Fetching
AppStore JSON APIs
Let's go ahead and wrap up the entire screen by fetching data and also transitioning into the AppDetailController upon tapping. Setting up this is much easier with a CompositionalLayout as we no longer have to deal with nested collection views.

Hey Brian, super genius man! Downloaded your code, was wondering if there's a difference between these two for dispatchGroup order Thanks man! Your code: dispatchGroup.enter() Service.shared.fetchGames { (appGroup, err) in self.games = appGroup dispatchGroup.leave() } My code : dispatchGroup.enter() Service.shared.fetchGames { (apps, err) in dispatchGroup.leave() self.games = apps }

Not sure if you have noticed the same issue but when I scroll up, I'm unable to scroll back down. There is no crash and I can move between screens. Thoughts?
