AsyncBluetooth is a Swift Package Manager library that brings Swift Concurrency to CoreBluetooth. It wraps the central manager and peripheral delegate APIs into async/await methods and AsyncStreams, so clients can scan, connect, discover services and characteristics, read/write values, and subscribe to notifications without nested delegate callbacks. It is not a standalone application; it is a dependency library for Apple-platform apps performing Bluetooth Low Energy central-role work. Architecturally, the code is split into CentralManager and Peripheral layers, with supporting types for scan data, services, characteristics, and events. A notable internal component is CentralManagerContext, a serialized async work queue that guarantees per-key operation ordering and supports cancellation. CoreBluetooth callbacks are translated into typed event enums such as CentralManagerEvent and exposed as AsyncStreams. The library uses os.log for diagnostics and ships a privacy manifest, indicating modern Apple platform practices. Maintenance is active: the repository has recent commits and a 6.2.2 tag. The code uses current Swift concurrency features, has no third-party dependencies, and includes tests. Technical drift is low.
