Why is the UIKeyboard implementation still holding a reference to this UITextField, thus keeping it from being deallocated? The memory debugger shows: UIKeyboardImpl -> UIKBAutofillController -> NSMutableDictionary -> NSMutable...(Storage) -> UITextField Any idea what's going on there?

My app uses UDP broadcast to find out a peer on a private network (169.254..). With iOS 14 and iOS 15 everything works fine, but on the newly released iOS 16 release candidate I get a 'Socket Error 65: No Route To Host'. I don't have any special entitlements for this app. Did anything change with regards to UDP broadcast policies from iOS 15 to iOS 16?
