Today Extension deleting data in sqlite

I have added Today extension in my existing app and setup a separate core data stack(reusing the same code which is used to setup core data for main app).
My app data gets deleted when I run the Today extension as if setting up of Today core data stack deletes the existing data.Refer below code for returning persistentCoordinator:

 let options = [NSMigratePersistentStoresAutomaticallyOption:true,
                      NSInferMappingModelAutomaticallyOption:true,
                                       NSSQLitePragmasOption:["journal_mode":"MEMORY"]]

var coordinator: NSPersistentStoreCoordinator? = NSPersistentStoreCoordinator(managedObjectModel: self.managedObjectModel)
            if coordinator!.addPersistentStoreWithType(NSSQLiteStoreType, configuration: nil, URL: storeURL, options: options, error: &error) == nil {

    NSLog("Unresolved error \(error)")
            }
            return coordinator

Any solution?
