SwiftUI + Combine:如何使用动画将数据分配给模型

import SwiftUI
import Combine

struct ContentView: View {
    @State private var data = 0
    private let publisher = PassthroughSubject<Int, Never>()
    private var cancellables = Set<AnyCancellable>()

    var body: some View {
        VStack {
            Text("Data: \(data)")
                .animation(.spring(), value: data)
            Button("Increment") {
                data += 1
                publisher.send(data)
            }
        }
        .onReceive(publisher) { newValue in
            self.data = newValue
        }
        .padding()
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
