Explain the concept of Core Bluetooth in IOS development.

Core Bluetooth is a framework in iOS development that allows developers to integrate Bluetooth functionality into their applications. It provides a set of APIs that enable communication between iOS devices and other Bluetooth-enabled devices, such as sensors, peripherals, and accessories.

With Core Bluetooth, developers can discover nearby Bluetooth devices, establish connections, and exchange data between devices. It supports both central and peripheral roles, allowing an iOS device to act as either a central device that scans and connects to peripherals, or as a peripheral device that advertises and provides services to other devices.

The framework also handles the underlying Bluetooth protocols and manages the communication process, making it easier for developers to implement Bluetooth features in their apps. Core Bluetooth supports various Bluetooth profiles, such as the Generic Attribute Profile (GATT), which defines the structure and behavior of Bluetooth Low Energy (BLE) devices.

Overall, Core Bluetooth simplifies the integration of Bluetooth functionality into iOS apps, enabling developers to create innovative applications that can interact with a wide range of Bluetooth devices.
