UPDATE: SUBMIT BUG REPORTS AND REFERENCE THIS NUMBER: #18882445
I keep having this error come up randomly through various compile times (even if nothing seems wrong with the app)
[PLLogging] ***** Error: logging directory does not exist /var/mobile/Library/Logs/CrashReporter/DiagnosticLogs/
I can't find anything online.
I have tried cleaning the project, multiple devices, and re-installing Xcode. If you have any advice on this issue I'd love to hear it!
I am running Xcode 6.1 on Yosemite and all the devices tested were running OSX 8.1
Just go to, iOS Simulator -> Reset Content and Settings. It will restore the default settings for iOS Simulator. Remember it will also removes all apps installed in Simulator.
It's a bug in iOS. Restarting the device fixed my issue. Also check the default camera app. In my case default camera was also not working.
I was doing some programming with the file manager so it's probably related.
Exit Xcode, delete all of the DerivedData and restarted iPad, now works.
Xcode 6.2, iOS 8.2
I faced a similar issue when I was tried to use parse with a swift project. I tried to delete all the libraries that I was using and add them again but didn't work so I restored my project from the last git version and I manually adding the new versions of the files. It is not fancy solution but Is quicker than fight with xcode to solve the issue.
