What are App Store Analytics: App Store Crashes?
“App Store Analytics: App Store Crashes” is a usage metric available to iOS developers. It measures the number of times your app has crashed on devices running iOS 8 or tvOS 9, and beyond.
To access detailed crash logs for your app(s), visit Xcode and navigate to the “Crashes” organizer. Once inside, you’ll be able to view unique totals for each kind of crash, as well as the number of users who experienced them. You’ll also be able to change the names of specific reports, mark reports as resolved, view the source code for stack frames, go to the source code where crashes occurred, and more.
