Rotating camera on swipe

I have a simple script that detects mobile swiping gestures.

 #pragma strict
 
 var minSwipeDistY : float;
 
 var minSwipeDistX : float;
 
 var Swipe: GUIText;
 
 private var startPos :Vector2; 
 
     function Update () 
     {
 
         if (Input.touchCount > 0) 
         {
 
         var touch : Touch = Input.touches[0];
 
         switch (touch.phase) 
 
             {
 
             case TouchPhase.Began:
 
             startPos = touch.position;
 
             break;
 
 
             case TouchPhase.Ended:
             var swipeDistVertical : float;
             swipeDistVertical = (new Vector3(0, touch.position.y, 0) - new Vector3(0, startPos.y, 0)).magnitude;
 
                 if (swipeDistVertical > minSwipeDistY) 
                 {
                     var swipeValue : float;
                     swipeValue = Mathf.Sign(touch.position.y - startPos.y);
 
                     if (swipeValue > 0)//up
                     {    
                         //Jump ();
                         print("You Swiped up");
                         //Swipe.text = "Up Swipe";
                     }
                     else if (swipeValue < 0)//down
                     {    
                         //Shrink ();
                         print("You Swiped down");
                         //Swipe.text = "Down Swipe";
                     }
                 }
                 var swipeDistHorizontal : float;
 
                 swipeDistHorizontal = (new Vector3(touch.position.x,0, 0) - new Vector3(startPos.x, 0, 0)).magnitude;
 
                 if (swipeDistHorizontal > minSwipeDistX) 
                 {
                     swipeValue = Mathf.Sign(touch.position.x - startPos.x);
 
                     if (swipeValue > 0)//right
                     {
                         //MoveRight ();
                         print("You Swiped right");
                         //Swipe.text = "Right Swipe";
                     }
                     else if (swipeValue < 0)//left
                     {    
                         //MoveLeft ();
                             print("You Swiped left");
                         //Swipe.text = "Left Swipe";
                     }
                 }
                 break;
             }
         }    
 
     }

But how do I make the camera its attached to rotate left or right depending on which way your swiping.
