title: Issue in displaying name of CBService and CBCharacteristic on central in Core Bluetooth
body: <p>I have created an application that act as a CBPeripheral.I am trying to display the name of Service and Characteristic on the connected Central but i am not able to find the way to do it. I have read the class reference of CBCharacteristic their is no variable like name in it. Their are some descriptors variable but they are for showing the characteristic value in human readable format. So I want to know, how to create a CBMutable characteristic so that its name is displayed on Central device. Can anyone help.</p>
  
  <p>This is my code for creating the characteristic</p>
  
  <pre><code>var characteristic = CBMutableCharacteristic(type: charId, properties: charProperties, value: nil, permissions: CBAttributePermissions.Readable|CBAttributePermissions.Writeable)
  </code></pre>
