Reading Crash Logs

This post will list the steps you need to take to read a crash log after receiving the crash log file.  This assumes you are using the same Xcode (6+) that you used to Archive the app.

1. Connect your iOS device.
2. Open Xcode
3. In the menu, go to Window->Devices
4. Select your iOS device and click on the View Device Logs button.
5. Select the "All Logs" tab.
6. If you crash log file does not have the .crash extension, rename it to have a .crash extension.
7. Drag the file into the device's log window.  Specifically, the left column.
8. Wait a minute or so until the list of logs shows the log you dragged in.
9. When your log shows up, right-click on your log and select Re-Symbolicate Log.
10. Once Re-Symbolicating is done you will have a readable crash log.
