This repo started out as a summary of all the Mastodon iOS apps I've found (see also the Awesome Mastodon list), but now it's also the issue tracker for my fediverse app in progress (available on Testflight) and a Swift package that currently comprises the middle layer between the UI and a fork of TootSDK.
While the development of both packages is oriented toward the app, the idea is to keep the TootSDK fork generally useful while the Fedicat package is app-specific, although it is an example how you can maintain session state, handle multiple sessions, and deal with multiple platforms. Feel free to use/fork/copy, but development is active so don't expect stability.
The forked and non-forked Swift packages used by Fedicat (the app) includes AlertToast, DiasporaNodeInfo, EmojiText, Fedicat, HTML2Markdown, ImagePickerView, Nuke, SwiftCollections, SwiftNIO, SwiftSoup, SwiftKeychainWrapper SwiftUI-Flow, SwiftUIKit, SwiftSys, and TootSDK.
