A Swift library providing closures-based APIs for CoreBluetooth, replacing delegate patterns with modern async callbacks.
SwiftyBluetooth is a Swift library that wraps Apple's CoreBluetooth framework, providing a closures-based API for Bluetooth Low Energy (BLE) operations. It simplifies BLE development by replacing delegate patterns with modern callback-driven methods for scanning, connecting, reading, writing, and handling notifications. The library handles automatic connections and service discovery, reducing boilerplate code and potential errors.
iOS developers building apps that interact with Bluetooth Low Energy devices, such as IoT gadgets, wearables, or smart home accessories. It's particularly useful for those who prefer modern Swift patterns over traditional delegate-based APIs.
Developers choose SwiftyBluetooth because it dramatically simplifies CoreBluetooth usage with a clean, closure-based API that reduces boilerplate and improves code readability. Its automatic connection management and precise error handling make BLE development more reliable and less error-prone compared to raw CoreBluetooth.

Replaces CoreBluetooth's verbose delegate patterns with clean closure callbacks for all operations, significantly reducing boilerplate and improving code readability, as shown in the scanning and reading examples.
Automatically handles peripheral connections and service/characteristic discovery when needed, minimizing manual setup and potential errors, as highlighted in the read/write operations.
Provides precise errors and guaranteed timeouts for every Bluetooth operation, enhancing reliability in unstable BLE environments, which is explicitly mentioned in the feature list.
Simplifies CBCentralManager state preservation and restoration setup via `setSharedCentralInstanceWith`, allowing seamless recovery of previous Bluetooth sessions, as detailed in the README.
The Central class is a Singleton, which complicates testing, dependency injection, and architectural flexibility, as it tightly couples Bluetooth management to a global instance.
Requires iOS 10.0 or higher, excluding support for older devices and potentially limiting app reach, as stated in the requirements section.
Uses NotificationCenter for events like characteristic updates, which might not integrate well with modern Swift concurrency or reactive frameworks without additional adaptation work.
