Apple's CoreBluetooth + Combine
CCBluetooth is a library that puts Apple's CoreBluetooth framework on Apple's reactive Combine framework. If you tired of managing CoreBluetooth delegates, states this library is for you. In addition this library has no third-party dependecies.
Inspired by RxBluetoothKit for RxSwift.
