Bluetooth modernized

The article introduces BLESwift and BLESwiftCLI, two open-source projects that leverage Swift 6.2's async/await features to simplify Bluetooth Low Energy (BLE) programming on Apple platforms. Unlike the traditional CoreBluetooth delegate-based approach that scattered logic across many callbacks and was error-prone, BLESwift offers a clean, linear, async/await interface that reads naturally and handles errors seamlessly. BLESwift also improves on earlier wrappers like Bluejay by fully embracing Swift's modern concurrency model with actor isolation, eliminating common threading and callback nesting issues. This results in more readable, maintainable, and robust BLE code aligned with current Swift best practices.
