进行 CKQuerySubscription 时“不明确地使用 'firesOnRecordCreation'”

Question

Xcode 抛出一个非常模棱两可的错误：

'firesOnRecordCreation' 的含糊使用

在进行 CKQuerySubscription 时。实际上，它在添加到该调用的每个选项上都这样做。那是编译器错误吗？解决方案？

let predicate = NSPredicate(value: true)
let subscriptionID = "notes-changed"
let noteSubscription = CKQuerySubscription(recordType: "Notes",
                                                   predicate: predicate,
                                                   subscriptionID: subscriptionID,
                                                   options: [.firesOnRecordCreation,
                                                             .firesOnRecordDeletion,
                                                             .firesOnRecordUpdate])

Answer 1

Which version of Xcode and Swift are you using? If you are on Swift 5, you need to use the full CKQuerySubscription.Options name like this:

let noteSubscription = CKQuerySubscription(
  recordType: "Notes", 
  predicate: NSPredicate(value: true), 
  subscriptionID: "notes-changed", 
  options: [
    CKQuerySubscription.Options.firesOnRecordCreation, 
    CKQuerySubscription.Options.firesOnRecordUpdate, 
    CKQuerySubscription.Options.firesOnRecordDeletion
  ]
)

I hope that helps.
