       DataAccess.shared.saveContext()
 

        let  containerPath = NSFileManager.defaultManager().containerURLForSecurityApplicationGroupIdentifier("group.weone.shareExtension")?.path
        let sqlitePath = NSString(format: "%@%@", containerPath!,"/WeOne")
        let url = NSURL(fileURLWithPath: sqlitePath as String)
         

If we have to pass some values from our app to share extension, Then we have to store those values in UserDefaults which can be done like this:

        var defaults = NSUserDefaults(suiteName: "group.weone.shareExtension")
        defaults?.setObject(textToShare, forKey: "textToShare")
        defaults?.synchronize()
 

For retreiving values in share extension we have to use follwing code :

       let defaults = NSUserDefaults(suiteName: "group.weone.shareExtension")
        defaults?.synchronize()
        let restoreTextValue = defaults!.stringForKey("textToShare")
 

restoreTextValue can be used for the value fetched.

Thanks
