The document discusses several techniques for making view controllers in iOS easier to understand, including using protocol extensions to segment protocols, reloading data using didSet when properties change, initializing views using declaration closures in viewDidLoad, and defining identifiers with static variables. The author presents these techniques as helpful ways to build view controllers that are more readable and maintainable.
