I was recently playing with an app and it suddenly crashed (it's happened to all of us). But, when I re-launched the app I got an alert that said, "Our app quit unexpectedly, would you like to send an error report so we can fix this?" This made me curious for two reasons: 1.) How was their app able to detect that it had crashed? 2.) What information did their app send that would help them fix the crash? Thank you for any help!
