iOSApp crash when shared via testflight with "COSMCtrl _foregroundAppActivity incoming bundle has nil supplied UUID, finds existing " error symptomsd in devicelog App works fine if distributed via AppCenter that uses AdHoc profile.

  • App only crashing when distributed via testflight but it works fine when shared with appcenter or in debug mode.
  • App is not crashing at launch time, it crashes after one screen so I think it may not be related to app signing certificate Dev
  • CPU spike is there on that event but its not that much its only 12 to 20% when checked in debug mode.
  • Yes I am doning some API hit at that point and parsing response JSON.

Any clue or suggestion will be appreciated.
