There's another restriction for keyboard extension. You should set RequestsOpenAccess to YES in Info.plist then it can access the files.

To get access to containing app bundle is sandboxed and not alloew to access from outside app. Call [[NSFileManager defaultManager] containerURLForSecurityApplicationGroupIdentifier:YOUR_APP_GROUP_ID] to obtain App Group Shared container's URL.

Note that using NSFileCoordinator inside extension to access containing app shared container may cause the deadlock. See this documentation
