SwiftUI - Debug Preview not working in Xcode 12 beta 2?

Nothing prints to the console when I tap on a button, although the debugger will break on the print() lines. I've chosen Debug Preview rather than just Live Preview in the Canvas, and I've tried restarting Xcode. Before I file feedback, is anyone else seeing this?

Code Block struct ContentView: View {
    var body: some View {
        VStack(alignment: .leading){
            Button("One Fish"){
                print("One")
            }
            Button("Two fish"){
                print("Two")
            }
        }
    }
}
