viewDidAppear not getting called

Question

In my main UIViewController I am adding a homescreen view controller as subviews:

   UINavigationController *controller = [[UINavigationController alloc] ini         


        

Answer 1

@Rob answer in Swift 4 (which helped me on my case which I was adding a childViewController to a UITabBarController)

override var shouldAutomaticallyForwardAppearanceMethods: Bool {
    return true
}
