Question

我有一个称为SearchResults的视图。每当传递给它的ObservedObject更改时，它都应该更新，但是View不会使用新值更新，我不确定为什么。

import SwiftUI

struct SearchResults: View {
    @ObservedObject var VModel: ViewModel
    var body: some view {
        List {
            ForEach(self.VModel.searchResults, id: \.self) { result in 
                Text(result)
            }
        }
    }
}


class ViewModel: ObservableObject {
    @Published var searchResults: [String] = []

    func findResults() {
        //Do the update to 'searchResults' here
        //This function is called at another point in the code in a pretty big file...I think it might make it more confusing to have like a couple hundred more lines of code in here
    }
}

侧面注意：VModel有一个[string]类型的数组，称为searchResults，我认为只要更新searchResults数组，此视图就应该更新。

很抱歉给大家带来的困惑，显然我真的很傻。我正在创建一个新的ViewModel（）实例，而不是传入ContentView中声明的实例

当传递给视图的ObservedObject更新时，SwiftUI是否不会更新？
