title: Connect to iBeacon
body: <p>I can scan for iBeacons with:</p>
  
  <pre><code>func locationManager(manager: CLLocationManager!, didRangeBeacons beacons: [AnyObject]!, inRegion region: CLBeaconRegion!) {
  
    }
  }
  </code></pre>
  
  <p>let suppose I get the following beacons after scanning</p>
  
  <pre><code>Beacon 1: major:1 minor:5 uuid:xxx
  Beacon 2: major:1 minor:6 uuid:xxx
  Beacon 3: major:1 minor:7 uuid:xxx
  </code></pre>
  
  <p>After the scan I want to connect to beacon 2 and change its characteristics.</p>
  
  <p>I know I can use CoreBluetooth to scan and connect to a Bluetooth device and change its characteristics, but the problem is how can I identify which device is beacon 2 via Core Bluetooth?</p>
