Dynamic Button with loop in SwiftUI

I'm using SwiftUI with Xcode-beta 4.

I want to create dynamic button with ForEach. I'm using these lines of code:

struct Result {
    var id = UUID()
    var score: Int
}

struct ContentView : View {
    let results = [Result(score: 8), Result(score: 5), Result(score: 10)]

    var body: some View {
        VStack {
            ForEach(results.identified(by: \.id)) { result in
                Button(action: {
                    print(result.score)
                }){
                    Text(result.score)
                }
            }
        }
    }
}

but Xcode can't compile this.

when I change Text(result.score) to Text("test") in button style, now Xcode can compile it

Since result.score is Int, you must convert it to String to show in Text(). Change your text button code to this one:

Text("\(result.score)")

To print an Int: Text("\(result.score)")

Also keep in mind that the ForEach syntax changed a little bit (Beta 5).
Now it should be: results.identified(by: \.id)

let results = [Result(score: 8), Result(score: 5), Result(score: 10)]

var body: some View {
    VStack {
        ForEach(results.identified(by: \.id)) { result in
            Button(action: {
                print(result.score)
            }){
                Text("\(result.score)")
            }
        }
    }
}

result
