Build cross-platform Mastodon and Fediverse integrations with TootSDK, a Swift library.
About TootSDK
TootSDK is an open-source Swift library for building cross-platform Mastodon and Fediverse client applications. It supports iOS, macOS, and Linux (via the Vapor framework), and is designed to work with major Fediverse servers including Mastodon, Pleroma, and PixelFed. The library provides tools for user authorization, post interactions, and access to user timelines.
It automatically detects server type and version on connection to adapt its behavior for compatibility, uses async/await for asynchronous operations, and standardizes model property names and API handling across supported Fediverse platforms. Full Swift concurrency support is planned for the Swift 6.2 release.
Key features
