The Swift Mailing Lists are a fantastic resource. However, accessing the information in a convenient way is difficult: The web archive is not easy to navigate, and when you subscribe to a list you're bound to the UI of a mailing list. Even worse, you can't see any messages posted before you subscribed.
Hirundo (Latin for 'Swift') is a convenient way to browse and follow the discussions in the Swift mailing lists like Swift-Evolution or Swift-Dev. You can even bookmark messages of threads because they contain important information
Hirundo integrates upcoming and accepted proposals. This makes it easy to identify things like SE-055 right away.
Browse and search everything posted to the lists
If you are subscribed to a list, Hirundo will open Mail.app with reply headers set
Messages are threaded, you can fold them or collapse them
The dashboard will show you interesting facts about the current state of the Swift ecosystem
