In my main UIViewController I am adding a homescreen view controller as subviews:
UINavigationController *controller = [[UINavigationController alloc] ini
When updating my code to 13.0, I lost my viewDidAppear calls.
In Objective-c, my solution was to add the following override all to the parent master view controller.
This allowed the ViewDidAppear call to get called once again...as it did in previous IOS (12 and earlier) version.
@implementation MasterViewController
//....some methods
