我已经设法让 CoreData 与 CloudKit 一起使用我的应用程序的 iOS 版本上的新 NSPersistentCloudKitContainer 并让它在应用程序运行时自动同步。但是，当我在 watchOS 应用程序上进行设置时，我注意到只有在我强制关闭并重新打开手表应用程序时才会发生同步。

import Foundation

        let cloudStoreUrl = applicationDocumentDirectory()!.appendingPathComponent("product.sqlite")

        let cloudStoreDescription = NSPersistentStoreDescription(url: cloudStoreUrl)
        cloudStoreDescription.shouldInferMappingModelAutomatically = true
        cloudStoreDescription.shouldMigrateStoreAutomatically = true
        cloudStoreDescription.cloudKitContainerOptions = NSPersistentCloudKitContainerOptions(containerIdentifier:"iCloud.com.company.product")

        container.persistentStoreDescriptions = [cloudStoreDescription]

        container.loadPersistentStores(completionHandler: { storeDescription, error in …
