当其他类中的ObservedObject发生更改时如何在ContentView中运行方法[Swift 5 iOS 13.4]

import SwiftUI

class MyModel: ObservableObject {
    @Published var someProperty: String = ""
}

import SwiftUI

struct ContentView: View {
    @ObservedObject var myModel = MyModel()
    
    var body: some View {
        VStack {
            Text(myModel.someProperty)
                .padding()
            
            Button(action: {
                // 在这里运行你的方法
                self.myModel.someProperty = "新值"
            }) {
                Text("更改属性")
            }
        }
    }
}
