SwiftUI 小部件不刷新

Question

我有一个每天午夜更新的小部件，我的时间线代码如下所示：

func getTimeline(for configuration: ConfigurationIntent, in context: Context, completion: @escaping (Timeline<ViewModel>) -> Void) {
        
    // Generate a timeline with one entry that refreshes at midnight.
    let currentDate = Date()
    let endOfDay = calendar.date(byAdding: .day, value: 1, to: currentDate)!
        
    API.getWordOfTheDay(for: currentDate) { result in
        switch result {
        case .success(let wordOfTheDay):
            let entry = ViewModel(date: currentDate, wordOfTheDay: wordOfTheDay, configuration: configuration)
            let timeline = Timeline(entries: [entry], policy: .after(endOfDay))
            completion(timeline)
                
        case .failure:
            break
        }
    }
}

问题是当我检查它时，小部件似乎永远不会在第二天更新。我已尝试将重新加载策略更改为 .atEnd，但这也不起作用。

任何建议可能是什么或我做错了什么？
