An open-source Swift package library designed to help other devs make apps that interact with the fediverse (like Mastodon, Pleroma, Pixelfed etc). We call it TootSDK ✨!

The main purpose of TootSDK is to take care of the “boring” and complicated parts of the Mastodon API, so you can focus on crafting the actual app experience.

I make apps and app tools!
