iPhone和Apple Watch应用之间的核心数据共享

Question

I need to share data stored using Core Data between my Apple Watch app and iPhone app. I found that I need to create a framework for the same from the follwing repo Apple Watch and Core Data

Also I've found the following code from Raywenderlich to share Core Data:

let kMyAppGroupName = "com.raywenderlich.mywatchapp.container"
var sharedContainerURL: NSURL? = NSFileManager.defaultManager().
 containerURLForSecurityApplicationGroupIdentifier(kMyAppGroupName)
 if let sharedContainerURL = sharedContainerURL {
 let storeURL = sharedContainerURL.URLByAppendingPathComponent("MyCoreData.sqlite")
 var coordinator: NSPersistentStoreCoordinator? = 
NSPersistentStoreCoordinator(managedObjectModel:self.managedObjectModel) coordinator?.addPersistentStoreWithType(NSSQLiteStoreType, 
configuration: nil,
URL: storeURL,
options: nil,
error: nil)
}

I've already done the iPhone part of the app using Core Data but I fail to share it with Apple Watch app. Can anyone suggest a way so that I can extend my current Core Data store to the apple watch app?

You could use the method openParentApplication:reply: to retrieve that information:
