Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

While you are correct about the stdlib, check out swift-algorithms (https://github.com/apple/swift-algorithms). It's written by Apple and has several interesting methods.

Do you use algorithms in Swift?
We used Swift Algorithms once or twice. It just depends on the app. I suggest starting with the WWDC video.

Swift. Algorithms contains chunks(ofCount: 3) but I had to write chunks(totalCount:) myself.

Understanding algorithms
There is also a swift algorithm package that’s a precursor to the standard library if you want to examine legit implementation built into Swift.

I used Algorithms and took inspiration from Kotlin with it's zipWithNext function.
