SwiftAudioFoundation (SAF) is an open-source Swift-native SDK for creating professional audio applications on Apple platforms. It provides a comprehensive set of real-time audio processing, MIDI, OSC, and UI components, enabling developers to build DAWs, synthesizers, effects, and other audio software entirely in Swift.
SAF is modular and highly performant, with a focus on Swift-style APIs and seamless integration with existing projects. The SDK can be integrated via Swift Package Manager (SPM), or used as a standalone framework for rapid prototyping and development.

Version 0.1.0 is the first official release of SwiftAudioFoundation. Earlier
versions have no source stability guarantees.
Because the SwiftAudioFoundation SDK is under active development, source
stability is only guaranteed within minor versions (for example, between 0.1.1
and 0.1.2). If you don't want potentially source-breaking package updates, you can
specify your package dependency using .upToNextMinorVersion(from: "0.1.0") instead.
Future minor versions of the package may introduce changes to these rules as needed.
