Button inside another button in SwiftUI

It works, just give enough space for internal button, so hit testing could designate which button to activate, like in below example. (Tested with Xcode 11.4 / iOS 13.4)

struct Foo: View {
    var body: some View {
        Button(action: { print("alloha") }) {
            HStack {
                Button(action: { print("hello") }) {
                    Image(systemName: "circle.fill").padding() // << more space !!
                        .border(Color.red) // << for testing
                }
                Text("world")
                Spacer()
            }
        }
    }
}

I am curious why you are adding button inside a button? I could use Two Buttons within a HStack like below. It will be obvious to user when tapping each buttons.

HStack {
    Button(action: { print("hello") }) {
        Image(systemName: "circle.fill")
    }

    Button(action: {
        print("World")
    }) {
        Text("World")
    }
}
