Appcast Workflow

Reusable workflow to generate Sparkle appcast.xml for my apps

Fork and use this for your own apps if you'd like. I'm happy to accept improvements, but I won't be accepting additional configuration. This workflow is tailored to my needs.

Setup

• Create a new repo.
• Enable GitHub Pages in the repo settings, then go to “Environments”, and in “Deployment branches and tags”, select “No restriction”.
• Export the EdDSA private key from Sparkle (./generate_keys -x private-key-file) and add it as a repo secret called SPARKLE_PRIVATE_KEY.
• Add this workflow file to the repo.
• Add the GitHub Pages URL to your app's Info.plist with the key SUFeedURL. For example, https://sindresorhus.com/quickgpt-meta/appcast.xml.

Publish update

• Create a new release on the repo and add the zipped app bundle as a binary to the release.
  • To mark an update as criticial, include <!-- CRITICAL_UPDATE --> in the release notes.
