"An Unknown error occurred" 尝试启动我的 Siri 快捷方式时

Question

我正在将 siri 快捷方式添加到我现有的应用程序中。 有三个快捷方式，一个用于使用特定值启动应用，一个用于按量增加值，另一个用于将值减少一定量。用于启动应用程序的快捷方式代码附在此处：

//
//  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"快捷指令"应用运行快捷方式时，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}.

Answer 1

我遇到了完全相同的错误，因为我不小心在 IntentHandler.swift 文件中返回了我的 CustomIntent 而不是我的 CustomIntentHandler

以前：

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

后：

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