IOS 8 App Group Access Container Application File in Keyboard Extension

I want to access the container application file in my custom keyboard extension through the application group function. For this purpose, I created a group identifier on my Apple portal, and also added it to both of my targets (keyboard and application). I successfully access the data through NSUserDefaultsmy work, I can access the data. But I'm stuck in getting a file from a container application. I have an access url

NSURL *containerURL = [[NSFileManager defaultManager] 
           containerURLForSecurityApplicationGroupIdentifier:@"group.com.company.app"];

NSURL Returns the URL as follows.

/Users/AxisCyberTech1/Library/Developer/CoreSimulator/Devices/1649BBF4-6615-4E53-BFC9-A3D07F3CA70A/data/Containers/Shared/AppGroup/49A4F24B-30A8-474E-8FFA-072E0DF61CBD/

but this path does not have access to any file from the container source package. How can I access the container container file

There is another limitation for keyboard expansion. You must set RequestsOpenAccess to YES in Info.plist, after which it will be able to access the files.

To access the containing application package, the sandbox is isolated, not alloew for access from outside the application. Call [[NSFileManager defaultManager] containerURLForSecurityApplicationGroupIdentifier:YOUR_APP_GROUP_ID]to get the container url for the application group.
