We have some crash which we cannot reproduce in our builds. I can see the one of this crashes in TestFlight and want to research it. I click "open in Xcode" in TestFlight. The crash is supposed to be opened in Xcode's organizer. But the crash opened by Xcode has another build number. I know I can list crashes by the small control on the bottom of the organizer. There is no one crash with the same build number that noted in TestFlight. So it's look like crash never downloaded to the Xcode. It looks like for some reason Xcode does not see crashes listed in TestFlight. I've also check all crashes Xcode knows about. It looks like Xcode does not see the big part of crashes listed in TestFlight. What could it be?

I have a VoIP-call app, and when the user answers call, sends app to the background and then taps "Touch to return to call" green bar on the top – I want to take additional steps after he returns to the app (show him the in-app call screen instead of the screen presented before the user sends app to the background). Is there any way to detect/handle these events? Like app delegate's application(continue userActivity:)? I can't use applicationWillEnterForeground because this event occurred not only when the user taps "Touch to return to call" but even if he just taps the app's icon or returns to the app using the application manager.
