Easily View TestFlight Installation, Session, and Crash Totals.
The total number of installations, sessions, and crashes are now displayed next to your beta builds in the Internal Testing and External Testing sections in TestFlight.
To view crash reports, open the Crashes organizer in Xcode. Please note that your app must be set up to include symbols in order to activate crash report services. You can manage this setting in Xcode when uploading your app to iTunes Connect.
For more information on enabling and analyzing crash data, see the App Distribution Guide.
