Help with Building an Executable

Using Swift
1

When I follow the instructions in PackageManager - Building an Executable

$ mkdir Hello
$ cd Hello
$ swift package init --type executable
$ swift run Hello
Compile Swift Module 'Hello' (1 sources)
Linking ./.build/x86_64-apple-macosx10.10/debug/Hello
Hello, world!

I get an Invalid manifest error.

> swift run Hello
error: 'hello': Invalid manifest
/Users/ibex/tmp/Hello/Package.swift:4:8: error: no such module 'PackageDescription'
import PackageDescription
       ^

What am I doing wrong?

I have Xcode Version 14.0 (14A309).
