“发生未知错误”尝试启动我的 Siri 快捷方式时

Question

我正在向我现有的应用程序添加 siri 快捷方式。共有三种快捷方式，一种以特定值启动应用程序，一种用于将值增加一个量，另一种用于将值减少一个量。快捷方式代码，用于启动应用程序附在此处：

//
//  StartMeetingIntentHandler.swift
//


import Intents
import SwiftUI

class StartMeetingIntentHandler: NSObject, StartMeetingIntentHandling {


    @ObservedObject var meeting = Meeting()

    func handle(intent: StartMeetingIntent, completion: @escaping (StartMeetingIntentResponse) -> Void) {
        if let attendees = intent.attendees {
            meeting.meetingStarted()
            meeting.addAttendee(numberToAdd: Int(truncating: attendees))
            completion(StartMeetingIntentResponse.success(result: attendees))
        } else {
            print("failure")
        }
    }

    func resolveAttendees(for intent: StartMeetingIntent, with completion: @escaping (StartMeetingAttendeesResolutionResult) -> Void) {
        let people = Int(truncating: intent.attendees ?? 0)
        if people < 0 {
            completion(StartMeetingAttendeesResolutionResult.unsupported(forReason: StartMeetingAttendeesUnsupportedReason.negativeNumbersNotSupported))
        } else if people > 1000 {
            completion(StartMeetingAttendeesResolutionResult.unsupported(forReason: StartMeetingAttendeesUnsupportedReason.greaterThanMaximumValue))
        } else {
            completion(StartMeetingAttendeesResolutionResult.success(with: people))
        }
    }
}

当我从快捷方式应用程序运行快捷方式时，我收到消息“发生未知错误”。如何进行调试？

查看模拟器的控制台后，我发现了两个错误： 1)

[INCExtensionRequest _extensionContextHost] Unexpected extension context class (null)

和 2)

-[WFAction runWithInput:userInterface:parameterInputProvider:variableSource:completionHandler:]_block_invoke Action <WFHandleCustomIntentAction: 0x7ffe845b1a10, identifier: com.theapapp.wastedtime.AddAttendeeIntent, parameters: 2> finished with error {domain: WFIntentExecutorErrorDomain, code: 103}.

}, WFIntentExecutorIntentErrorKey=<INIntent: 0x6000018f0630> {
    people = 1;
}, NSLocalizedFailureReason=Could Not Run Add Attendee}

Answer 1

我遇到了同样的错误，因为我不小心在 IntentHandler.swift 文件中返回了我的 CustomIntent 而不是我的 CustomIntentHandler

之前：

class IntentHandler: INExtension {
    override func handler(for intent: INIntent) -> Any {
        if intent is CustomIntent {
          return CustomIntent()
        }
        return self
    }
}

之后：

class IntentHandler: INExtension {
    override func handler(for intent: INIntent) -> Any {
        if intent is CustomIntent {
          return CustomIntentHandler()
        }
        return self
    }
}
