从日历中检索带有标识符的事件时应用程序崩溃

Question

当用户从日历中手动删除事件并且应用程序尝试从 EKEventStore 中检索带有标识符的 EKEvent 时，应用程序会崩溃并出现以下错误。

Error getting event with identifier AB78AC19-BD17-4290-8A21-4BF948089C12:66F6F5BC-BF61-401A-B808-44A555F7E63E: Error Domain=EKCADErrorDomain Code=1010 "The operation couldn’t be completed. (EKCADErrorDomain error 1010.)" fatal error: unexpectedly found nil while unwrapping an Optional value

这是用于获取标识符为

的事件的代码

let eventStore = EKEventStore()
let event = eventStore.event(withIdentifier: identifier as String)!

请帮我解决这个问题。

检查事件是否存在：

let eventStore = EKEventStore()
if let event = eventStore.event(withIdentifier: identifier as String) {
    //do what you need with the event
}
