Swift Playgrounds Compatibility

@Cay-Zhang
Adding this to Swift Playgrounds on iPadOS results in an error message: “package doesn't have version tags”. I fixed that in my fork by adding a new tag removing the “v“ prefix.

You can also have a look at this:

It should work in the latest version of Swift Playgrounds now.
