Confusing Crashlytics reports from TestFlight distributed app

Question

I'm using TestFlight to distribute a beta app and Crashlytics for crash reporting, but some of the reports I'm getting are pretty useless. Instead of revealing the problematic line of code, the stack trace shows something like this:

-[__TFAppUpdater_Helper .cxx_destruct] + 28868

I have commented out all of the TestFlight SDK calls in my code, but I'm still distributing with TestFlight. I can install the app on my own device via Xcode, bypassing TestFlight, and then Crashlytics produces a helpful report for the same crash. I've seen lots of evidence online that TestFlight and Crashlytics should play nice, but it hasn't been my experience so far.

Solution 2

As suggested, this turned out to be a symbolication issue and changing the build settings in Xcode fixed it. Though I'm not using their platform, I found the solution in the HockeyApp documentation:

For static libraries the build settings contain the following:

Strip Debug Symbols During Copy: No
Strip Style: Debugging Symbols
Strip Linked Product: No

For application targets or OS X frameworks, the build settings should contain the following for the release (App Store) build configuration:

Strip Debug Symbols During Copy: Yes
Strip Style: All Symbols
Strip Linked Product: Yes

OTHER TIPS

I had the same issue with my project the other day and found this tutorial that fixed the issue (by disabling testflight's crash handlers)
