We found your app crashed on launch so we were unable to review it.

Please revise your app and test it on a device to ensure it will launch without crashing, and that it runs as expected, before resubmitting.

Thank you for your resubmission. However, we were still unable to review your app, as it crashed on launch. We have attached detailed crash logs to help troubleshoot this issue.

Answer 1

I found the solution. We can just directly drag and drop the crash-report on the device log. Then it will convert the crash report into readable format.

STEPS:

1. Attach your device to mac.
2. Open Xcode
3. Goto window from menu bar
4. Click on devices like this

5. Now, drag and drop your crash report you received from apple. It will symbolicate it and show you in readable format. If the file extension is .txt, change it to ".crash".
