    From the below code the zoom is working with two fingers but my rotation is not working using single swipe.For testing i added a text.The text is getting updated with "One touch move" when I swipe the screen.
    Cannot understand the zoom is working but the rotation not working.Any help?

    Code (CSharp):
    1.  void FixedUpdate()
    2.      {
    3. //I Have increased to higher values no use
    4.         public float rotspeed=100f;
    5.  
    6.  
    7.         if (Input.touchCount > 0 && isLocked==true)
    8.           {
    9.               var touch = Input.GetTouch(0);
    10.              
    11.                 if ((Input.touchCount == 1 && Input.touchCount < 2 && Input.GetTouch(0).phase == TouchPhase.Moved) && !EventSystem.current.IsPointerOverGameObject(touch.fingerId) )
    12.                      {
    13.                 // Get movement of the finger since last frame
    14.  
    15.                          Debug.Log("One touch Move");
    16.                          Vector2 touchDeltaPosition = Input.GetTouch(0).deltaPosition;
    17.                 Messagetxt.text = "One touch Move";
    18.  
    19.            
    20.               this.transform.Rotate(Vector3.up, -touchDeltaPosition.x * rotspeed * Time.deltaTime, Space.World);
    21.            
    22.  
    23.  
    24.                      }
    25.  
    26.  
    27.  
    28.             if (Input.touchCount == 2 &&  !EventSystem.current.IsPointerOverGameObject(touch.fingerId))
    29.                      {
    30.  
    31.  
    32.  
    33.  
    34.  
    35.                         // Store both touches.
    36.                         Touch touchZero = Input.GetTouch(0);
    37.                         Touch touchOne = Input.GetTouch(1);
    38.  
    39.                         // Find the position in the previous frame of each touch.
    40.                         Vector2 touchZeroPrevPos = touchZero.position - touchZero.deltaPosition;
    41.                         Vector2 touchOnePrevPos = touchOne.position - touchOne.deltaPosition;
    42.  
    43.                         // Find the magnitude of the vector (the distance) between the touches in each frame.
    44.                         float prevTouchDeltaMag = (touchZeroPrevPos - touchOnePrevPos).magnitude;
    45.                         float touchDeltaMag = (touchZero.position - touchOne.position).magnitude;
    46.  
    47.                         // Find the difference in the distances between each frame.
    48.                         float deltaMagnitudeDiff = prevTouchDeltaMag - touchDeltaMag;
    49.

    61.  
    62.                         }

    I am using the later ARcore sdk with HelloARcontroller for placing the object on real world
