使用watchOS 3时出现CloudKit错误(CloudKit error using watchOS 3)

 我相信我已经设置好一切，并且一切都适用于iOS模拟器中的CloudKit ，但我无法让CloudKit在Watch Simulator中工作：“无法发送有效的签名” 
 
 有谁知道为什么会这样？ 
 
 
 
 我知道CloudKit适用于每个Apple“iCloud交互的watchOS 3。从watchOS 3开始， WatchKit扩展可以直接与CloudKit和其他iCloud技术进行通信。” 
 
 
 我已经设置了> iCloud，然后使用您的Apple ID登录 
 在iOS模拟器上每次输入链接描述 
 
 
 在Watch Extension中，我在这里输入链接描述时使用CKContainer(identifier:"iCloud.com.xx.xx")调用CloudKit 
 
 
 我仔细检查了Apple的文档，以确保我没有错过任何东西： 
 在此输入链接描述 
 
 
 我正在Watch上访问同一个CloudKit容器 
 iOS，因此CloudKit数据的可访问性没有任何问题 
 
 
 具有容器标识符的CloudKit功能在Watch Target中正确设置 
 

I believe I have everything set up right, and everything works for CloudKit in the iOS Simulator, but I can't get CloudKit to work in the Watch Simulator: "Couldn't send a valid signature"
 
Does anyone know why this would be?
 
 
 
I know CloudKit works in watchOS 3 per Apple "iCloud interactions. Starting with watchOS 3, the WatchKit extension can communicate directly with CloudKit and other iCloud technologies."
 
 
I already did Settings > iCloud and then log in using your Apple ID
 on the iOS simulator per enter link description here
 
 
In the Watch Extension, I'm calling CloudKit using CKContainer(identifier:"iCloud.com.xx.xx") per enter link description here
 
 
I double-checked Apple's doc to make sure I didn't miss something:
 enter link description here
 
 
I'm accessing the same CloudKit container on the Watch that I am on
 iOS, so nothing is wrong with accessibility to the data in CloudKit
 
 
The CloudKit capability with the container identifier is set correctly in the Watch Target
