How are reports created?

Apple provides a report service that collects logs from users for apps that you distribute using TestFlight or distribute through the App Store. The service organizes the logs for the past two weeks into downloadable crash, energy, and metric reports. The service does the following:

• Collects logs from apps and app extensions running on user devices

• Symbolicates the logs (replaces memory addresses with human-readable names)

• Compares stack traces to identify and group similar logs into reports

• Removes all personal user data from logs

• Provides the total number of unique devices where the event occurred

• Provides a sample set of logs for each report

• Updates reports daily

You view crash reports in the Crashes organizer, energy reports in the Energy organizer, and metrics in the Metrics organizer. To open the organizer, choose Window > Organizer, then click either Crashes, Energy, or Metrics.
