In RSS 2 the description may contain the full text and the content can be omitted when there is not a short version available: https://cyber.harvard.edu/rss/rss.html#hrelementsOfLtitemgt

However a JSON feed will not contain a content_html field when the content is not provided.

This makes it hard to create both a JSON feed and an RSS 2 feed because providing content without a description will create a content:encoded field but not a description field in the RSS 2 feed.

My solution to this is to fallback to the item.description when item.content is not provided and generating a JSON feed.

This PR is to add support for running on watchOS. Since Xcode 12.5 watchOS has been supported but Nimble doesn't currently compile for watchOS.

A new target has been added to the project, along with explicit support in the Package.swift.

I don't believe anything here is a breaking change.

I have a fork of Quick that also supports watchOS. I'll create a PR for that if this PR gets approved and merged.

The package(s) being submitted are:

• VaporDocC
