1. Use gomobile bind to bind the golang.org/x/mobile/example/bind/hello package.
   The following command will create an XCFramework in the current directory.

  $ gomobile bind -target=ios golang.org/x/mobile/example/bind/hello

2. Open the Xcode project by double clicking on bind.xcodeproj.
   The project will not build - ViewController.m calls a function from the hello
   package so requires the Hello.xcframework that gomobile bind command created
   in Step 1.

3. Drag-and-drop Hello.xcframework from the desktop to the project navigation window.
   This will automatically include the Hello.xcframework into the project.

4. Build.
