I'm displaying a translucent UIToolbar as a subview of a UIViewController which is a child of a UINavigationController (I don't use the UINavigationController toolbar as I want to subclass it). Everything works fine but one thing: when I push another UIViewController on the UINavigationController stack, the next UIViewController edges are not extended behind the NavigationBar until the animation is over. The same issue occurs when the pop animation of the next UIViewController starts. Side notes: The NavigationBar is translucent (by default) Both UIViewControllers are set to extend edges under top and bottom bars The issue is not reproducible if the UIToolbar is not translucent (of if a tint is set). The same issue occurs if the UINavigationController is inside a UITabBarController: the next UIViewController edges are not extended under the tabBar. It's easily reproducible on iOS 12, iOS 13 and iOS 14 devices/simulators, with no code, just storyboard editing. Here's a link to the StackOverflow post I've created a month ago with no feedback from the community: https://stackoverflow.com/questions/63424459/uiviewcontroller-edges-not-extended-behind-top-bottom-bars-during-a-uinavigation

Hi, We develop an app that sends multicast requests on the local network in order to look for our proprietary hardware (using sockets) and I understand that it now requires the Multicast Networking entitlement (for which I've applied and received no response from Apple yet). However, I'm concerned about the app currently in production on the App Store, and how it behaves on various versions of iOS. Especially, it seems our app (built with Xcode 11) is still able to send multicast requests even if run on an iOS 14 device. However the app built with Xcode 12 systematically fails to send requests on the local network (through CFSocketSendData) on the same iOS 14 device, the local network access being properly granted by the user. Hence my questions: Is the Multicast Networking entitlement only required for apps built since iOS 14 is available (so with Xcode 12)? If so, how long do we have before an update is required with the proper entitlement? Or have I missed something?! Thanks for your time.
