UIWindow. В этом классе настраиваются все основные потребности вашего приложения, будь то Push Notifications или Voice Calls и так далее. Я бы сказал это Core вашего приложения.UIResponder и UIApplicationDelegateAn abstract interface for responding to and handling events.
A set of methods that are called by the singleton UIApplication object in response to important events in the lifetime of your app.
appDelegate.getApiService(...).getRequests(...) во viewDidAppear. Present view controller'a не должен вызываться во viewDidLoad.
