BlueCap

Replaces CoreBluetooth's delegate and block patterns with a chainable futures interface using SimpleFutures, reducing nested callbacks and scattered state management, as demonstrated in the CentralManager example with flatMap chains.

Provides built-in timeouts for peripheral connections, service/characteristic discovery, and read/write operations—a feature CoreBluetooth lacks—helping prevent hanging operations.

Includes a domain-specific language for defining reusable GATT service and characteristic profiles, simplifying profile management and reuse across projects.

Offers ready-made types for encoding and decoding characteristic data, handling data conversion seamlessly without manual parsing.

Comes with full example apps for CentralManager and PeripheralManager, plus a scanner/simulator app on the App Store, accelerating development and testing.
