Hi @tomsean! I love that AllowsBackForwardNavigationGestures preference, nice addition!

Can you tell me what the remote url bug was precisely? Cheers!

yes,you can just replace with .and then this will not work.
the reason is
after run
MyMainViewController *myMainViewController = [[MyMainViewController alloc] init];
self.viewController = myMainViewController;
self.window.rootViewController = myMainViewController;
code MyMainViewController viewDidLoad is runed
and then this time
"_startURL" is nil inMyMainViewController viewDidLoad method 277 line
so bug is come.
