iOS 14 SwiftUI UIViewRepresentable updateUIView检测不到ObservedObject更改？

import SwiftUI

struct MyView: UIViewRepresentable {
    @ObservedObject var myObject: MyObject
    
    func makeUIView(context: Context) -> UIView {
        let view = UIView()
        // 设置视图的初始状态
        return view
    }
    
    func updateUIView(_ uiView: UIView, context: Context) {
        // 在这里更新UIView的外观
        
        // 检测ObservedObject的更改
        if myObject.someProperty {
            // 执行相应的操作
        }
    }
    
    func makeCoordinator() -> Coordinator {
        Coordinator(self)
    }
    
    class Coordinator: NSObject {
        var parent: MyView
        
        init(_ parent: MyView) {
            self.parent = parent
            super.init()
            
            // 监听ObservedObject的更改
            self.parent.myObject.objectWillChange
                .sink { _ in
                    // 更新UIView
                    self.parent.updateUIView(self.parent.uiView, context: self.parent.context)
                }
                .store(in: &cancellables)
        }
        
        var cancellables = Set<AnyCancellable>()
    }
}

class MyObject: ObservableObject {
    @Published var someProperty: Bool = false
    // 其他属性和方法...
}
