The Core Bluetooth framework provides the classes needed for your apps to communicate with Bluetooth-equipped low energy (LE) and Basic Rate / Enhanced Data Rate (BR/EDR) wireless technology.
Don’t subclass any of the classes of the Core Bluetooth framework. Overriding these classes isn’t supported and results in undefined behavior.
Core Bluetooth background execution modes aren’t supported in iPad apps running on macOS.
