SwiftUI asynchronous operation example

About

This SwiftUI application demonstrates how to schedule synchronous and asynchronous work when a Button is tapped.

Refer to the four Buttons in the ContentView struct. Each Button calls into a function of a MainActor view model either directly or via a Task. Each of the functions in the view model is declared as nonisolated or async or neither or both.
