Ideally, the crash report should be available to developers via the iTunes connect channel.
However, there sometimes the crash reports are not reported there.

Below you can find a simple procedure of recovering the crash report from your device:

Sending Crash Reports from Macs
To send crash logs to developers:

1. In the Finder, open a new window.
2. Choose Go > Go to Folder.
3. Enter ~/Library/Logs/CrashReporter/MobileDevice.
4. Open the folder named after your device’s name.
5. Select the crash logs named after the application you’re testing.
6. Choose Finder > Services > Mail > Send File.
7. In the New Message window, enter the developer’s email address in the To field and <application_name> crash logs from <your_name> (for example, MyTestApp crash logs from Anna Haro) in the Subject field.
8. Choose Message > Send.
9. In the Finder, you may delete the crash logs you sent to avoid sending duplicate reports later.

Sending Crash Reports from Windows
To send crash logs to developers, enter the crash log directory (Listing 9-1 and Listing 9-2) in the Windows search field, replacing <user_name> with your Windows user name.

Listing 9-2 Crash log storage on Windows XP

Open the folder named after your device’s name and send the crash logs for the application you’re testing in an email message using the subject-text format <application_name> crash logs from <your_name> (for example, MyTestApp crash logs from Anna Haro) to the application’s developer.

You can then send the crash report to email: forum@ this domain (wdtvremote.com)
