WidgetKit 不适用于 Intent Handler 提供动态值

如何解决WidgetKit 不适用于 Intent Handler 提供动态值

我正在尝试实现一个小部件，用户可以在其中通过意图动态选择城市。

我按照苹果在此处提供的分步指南进行操作： https://developer.apple.com/documentation/widgetkit/making-a-configurable-widget

我认为我做的一切都是正确的，但我的结果总是这样：

我可以看到城市列表，但当我选择一个城市时，屏幕变黑，如视频所示，调试崩溃。在模拟器和设备上。

我的目标是在小部件的 getTimeline 中选择城市

这是我使用的代码：

SiriIntent 目标中的 IntentHandler.swift：

import Intents

class IntentHandler: INExtension,DynamicCitySelectionIntentHandling {
    func provideCity_paramOptionsCollection(for intent: DynamicCitySelectionIntent,with completion: @escaping (INObjectCollection<City>?,Error?) -> Void) {
        let dataSource = PersistenceController.shared.getAllForecastDataCoreData()
        
        let coreDataCities: [City] = dataSource.map { cityCoreData in
            let city = City(identifier: "\(cityCoreData.cityID ?? -1)",display: cityCoreData.cityName ?? "")
            return city
        }
        
        let collection = INObjectCollection(items: coreDataCities)

        completion(collection,nil)
    }
    
    override func handler(for intent: INIntent) -> Any {
        return self
    }
}

Widget 类中的部分代码：

import WidgetKit
import SwiftUI
import Combine
import MapKit

typealias Entry = ForecastEntry

struct Provider: IntentTimelineProvider {
    
    let snapshotEntry = Entry(date: Date(),forecastViewModel: .initForPlaceholder())
    
    func placeholder(in context: Context) -> ForecastEntry {
        snapshotEntry
    }
    
    public func getSnapshot(
      for configuration: DynamicCitySelectionIntent,in context: Context,completion: @escaping (Entry) -> Void
    ) {
        let entry = snapshotEntry
        completion(entry)
    }
    
    public func getTimeline(
      for configuration: DynamicCitySelectionIntent,completion: @escaping (Timeline<Entry>) -> Void
    ) {
        
        let currentDate = Date()
        let correctDate = Calendar.current.date(byAdding: .second,value: 150,to: currentDate)
        WidgetServiceManager.shared.fetchWeather(forCityId: configuration.city_param?.identifier ?? "") { data in
            guard let _data = data else { return }
            let entry = Entry(date: currentDate,forecastViewModel: ForecastCardViewModel(weatherModel: _data,isForUserPosition: false))
            let timeline = Timeline(entries: [entry],policy: .after(correctDate ?? Date()))
            completion(timeline)
        }
    }
}

@main
struct WeatherAppWidget: Widget {
    let kind: String = "WeatherAppWidget"
    
    init() {
    }
    
    var body: some WidgetConfiguration {
        IntentConfiguration(
          kind: kind,intent: DynamicCitySelectionIntent.self,provider: Provider()
        ) { entry in
            WeatherAppWidgetEntryView(entry: entry)
        }
        .configurationDisplayName("Weather Widget")
        .description("Forecasts in your location.")
        .supportedFamilies([.systemMedium,.systemSmall])
    }
}
