Retrieving crash logs from iTunes
Sometimes we see crashes reported in the App Store that we cannot find matching crash logs for. In these situations it would help us if we can be sent log files that iPhone stores using iTunes. If you have been directed to this post, please follow the steps below to send us log files.
-Open Finder (found in the Dock)
-Click on the 'Go' menu at the top of your screen, and select 'Go to Folder'
-Type (or paste): ~/Library/Logs/CrashReporter/MobileDevice/
-Open the folder with the same 'name' as your device. Look for files starting with App_ date so like GONavigation_26-09-2019
-Open any Windows Explorer Window (My Computer, My Documents, etc.)
-Enter %appdata%, and press enter
-Navigate to Roaming > Apple computer > Logs > CrashReporter > Mobile Device > *Device Name*. (Note: your device name appears in iTunes on the left side, under 'Devices')
-Look for files starting with App_ date so like GONavigation_26-09-2019
You can send these crash logs directly to @Jürgen via private message.
