Erro "Espera-se que as janelas do aplicativo tenham um controlador de exibição raiz no final do lançamento do aplicativo" ao executar um projeto com o Xcode 7, iOS 9
Depois de executar a função
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
há um acidente:
Assertion failure in
-[UIApplication _runWithMainScene:transitionContext:completion:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit_Sim/UIKit-
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', `enter code here`reason: 'Application windows are expected to have a root view controller at the end of application launch'

Este projeto é um projeto antigo, o que devo fazer para criar e executar o Xcode 7 e o iOS 9?
