Dragging Planes doesn't work with iOs?

Hello community

I have series of planes facing my FPS Camera

when I click and drag the plane away the FPS Camera Lerps forward and I am faced with the next which I drag away etc...

My script (below) works in unity, but Not in iOs... The Loading Screen freezes (& I only have a few photo textures on a few planes)

Any ideas?

Thanks!

 var myFPS: Transform;
 var camPos: Vector3; 
 var endPos: Vector3;
 var time : float;
 
 var someBoolean : boolean = false;
 var dragBoolean : boolean = false;
 var drag: float = 0.01; // drag factor
  
  
  
 function Start () {
 
 }
 
 function Update () { // FOR CAMERA
   //  Debug.Log ("nope");
 if(someBoolean == true) {
     myFPS.transform.position.z = Mathf.Lerp(camera.main.transform.position.z, endPos.z, .5f * Time.deltaTime);
     //Debug.Log ("true");
     }
 }
 
 
 function FixedUpdate(){// FOR DRAG
     var vel = rigidbody.velocity;
     rigidbody.constraints = RigidbodyConstraints.FreezeRotationX | RigidbodyConstraints.FreezeRotationY | RigidbodyConstraints.FreezeRotationZ;
     vel.x *= 2.0-drag; // reduce x component...
     vel.y *= .0-drag; // and z component each cycle
     vel.z *= .0-drag;
     rigidbody.velocity = vel;
   }
   
   
   
       function OnMouseUp () {
  dragBoolean = true;
 //    Debug.Log ("Drag");
  someBoolean = true;
 //    Debug.Log ("Move");
     yield WaitForSeconds(1);
     someBoolean = false;
     
     }
