小部件不刷新新数据

Question

在我的iOS 14应用中，我正在解析一个RSS feed，并且该Widget应该在数组中显示最新的条目[0]。这是可行的，但是，当添加任何新条目时，它不会更新。我已经尝试过.atEnd并设置了一定的分钟数，但它没有改变。为了确认解析器不是问题，我将构建安装在其他设备上，该设备显示了最新条目，而具有第一个构建的原始设备仍仅显示安装时是最新版本的设备。

struct Provider: TimelineProvider {
    @State private var rssItems:[RSSItem]?
    let feedParser = FeedParser()
    func placeholder(in context: Context) -> SimpleEntry {
        SimpleEntry(date: Date(), title:"News", description: "News article here", link: "Http://link", pubDate: "The day it posted")
    }

    func getSnapshot(in context: Context, completion: @escaping (SimpleEntry) -> ()) {
        let entry = SimpleEntry(date: Date(), title:"News", description: "News Article Here", link: "Http://link", pubDate: "The day it posted")
        completion(entry)
    }

    func getTimeline(in context: Context, completion: @escaping (Timeline<SimpleEntry>) -> ()) {

        var entries: [SimpleEntry] = []
        
        
        feedParser.parseFeed(url: "https://fritchcoc.wordpress.com/feed") {(rssItems) in
            self.rssItems = rssItems
            let currentDate = Date()
            let string1 = "Latest News: \n\n"
            let string2 = rssItems[0].title
               
            
            
            
            
            
            
            
                var appendString1 = string1+string2
                let entry = SimpleEntry(date: currentDate, title:appendString1, description: rssItems[0].description, link: rssItems[0].link, pubDate: rssItems[0].pubDate)
                entries.append(entry)
            
            let timeline = Timeline(entries: entries, policy: .atEnd)
            completion(timeline)

        }
       
    }
}

struct SimpleEntry: TimelineEntry {
    let date: Date
    let title: String
    let description: String
    let link: String
    let pubDate: String

struct FritchNewsEntryView : View {
    var entry: SimpleEntry
    var body: some View {
           
        VStack(alignment: .leading, spacing: 4) {
            Text(entry.title)
                                .font(.system(.title3))
                                .foregroundColor(.black)
                            Text(entry.pubDate)
                                .font(.system(.callout))
                                .foregroundColor(.black)
                                .bold()

                                .font(.system(.caption))
                                .foregroundColor(.black)
                           
              
            }
       
        
        .frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity, alignment: .leading)
                .padding()
                .background(LinearGradient(gradient: Gradient(colors: [.orange, .yellow]), startPoint: .top, endPoint: .bottom))
