如何为 discoverAllContactUserInfosWithCompletionHandler 创建优先级高于默认值的 CKOperation？
我找不到不使用 [[CKContainer defaultContainer] discoverAllContactUserInfosWithCompletionHandler: 查询所有用户信息的示例，它的优先级很低，需要很长时间才能完成。
discoverAllContactUserInfosWithCompletionHandler 的 CloudKit 文档是这样说的：
This method searches for the users asynchronously and with a low
priority. If you want the task to execute with a higher priority,
create a CKDiscoverAllContactsOperation object and configure the
desired priority.
您可以这样设置优先级：
var operation: CKDiscoverAllContactsOperation = CKDiscoverAllContactsOperation()
operation.queuePriority = NSOperationQueuePriority.High
