-- Use `example-app` scheme to build and test the example app package with all contained libraries.
-- Use `ExampleAppIcon` scheme with macOS target to build and preview the example app icon.
-- Use `example-app-icon-export` scheme with macOS target to build and update the example app icon.
-- Use other schemes, like `XXClient`, for building and testing individual libraries in isolation.
