A service with writeable property values.
Declaration
class CBMutableServiceOverview
The CBMutableService class adds write access to all of the properties in the CBService class it inherits from. You use this class to create a service or an included service on a local peripheral device (represented by a CBPeripheralManager object). After creating a service, you can add it to the peripheral’s local database using the add(_:) method of the CBPeripheralManager class. After you add a service to the peripheral’s local database, Core Bluetooth caches the service and you can no longer make changes to it.
