Hi, I've been running https://swiftpack.co for quite some time, but never posted it here. It crawled GitHub, searching for swift packages, and it's still the largest collection to my package. I'll be posting updates here and any feedback is obviously welcome. And the whole website is written in Swift using Vapor.
I’ve found it very useful myself.
I've added easy access to release notes of packages straight from the main page https://swiftpack.co
The website seems to be down right now, unfortunately.
Are you using GitHub releases or tag annotations as release notes? I prefer the latter (particularly since they are part of the repository itself), but Xcode seems to only use the former.
