Siri Intent捐赠报错：无有效快捷方式类型问题排查求助

我在Intent Handler的日志中发现了无法理解的问题，调用INInteraction.donate()时抛出错误，提示**"Cannot donate interaction with intent that has no valid shortcut types"**。

相关代码（添加参会者函数） #

func addAttendee(numberToAdd: Int) -> Int {
    self.numberOfAttendees += numberToAdd
    let intent = AddAttendeeIntent()
    intent.suggestedInvocationPhrase = "Add People"
    intent.people = NSNumber(value: numberToAdd)

    let interaction = INInteraction(intent: intent, response: nil)

    interaction.donate { (error) in
        if error != nil {
            if let error = error as NSError? {
                self.logger.log("error occurred: \(error, privacy: .public)")
            }
        } else {
            self.logger.log("Add people Intent success")
        }
    }
    return (self.numberOfAttendees)
}

Intent定义检查 #

我确认过Intent的定义配置（截图显示配置项完整），没有发现问题。

Intent Handler代码 #

override func handler(for intent: INIntent) -> Any {
    // This is the default implementation.  If you want different objects to handle different intents,
    // you can override this and return the handler you want for that particular intent.
    logger.log("\(intent)")

    switch intent {
    case is AddAttendeeIntent:
        return AddAttendeeIntentHandler()
    case is RemoveAttendeeIntent:
        return RemoveAttendeeIntentHandler()
    case is StartMeetingIntent:
        return StartMeetingIntentHandler()
    case is EndMeetingIntent:
        return EndMeetingIntent()
    case is ResetMeetingIntent:
        return ResetMeetingIntent()
    case is QuorumReachedIntent:
        return QuorumReachedIntent()
    default:
        fatalError("Shortcut - No handler for this intent")
    }
}

疑问 #

我不清楚"无有效快捷方式类型"具体指什么。另外尝试修改Intent Handler的AddAttendee分支时，系统提示该类型不存在。请问我忽略了什么细节？
