Please assist me interpret stacktrace of a crashlog.
My iOS app crashes on coming into foreground whereas being in background for a while. Crashlogs say that the watchdog terminated the app for being lively for too lengthy. Thats okay. My query is, how do I decide what precisely my app was doing in background for therefore lengthy? Stacktrace seems to be like a very regular clear launch with app being killed on the finish.
