AddComponent(MeshCollider) not working on Android/iOS

I have a map where I have to add collider data on the fly for visible objects in the renderer. Here's my function that does this:

   function optimize(){
 
    var i : int;
     var objects : GameObject[] = FindObjectsOfType(GameObject) as GameObject[];
 
     for(i = 0; i<objects.Length; i++){
 
         if(objects[i].renderer && objects[i].name != "MagicObj"){
 
             if(objects[i].renderer.isVisible == true)
             {
                 Debug.Log(objects[i].name);
                 objects[i].AddComponent.<MeshCollider>();
                 //objects[i].renderer.material.color = Color.red;
                 objects[i].collider.enabled = true;
             }
         }
     }
 }

When building on PC/Web, this works flawlessly, and as expected. On Android, it doesn't seem to add the MeshCollider correctly. I confirmed this when attempting to Raycast against an object that was supposed to have its collider added on the fly. I get a NullReferenceException (basically no hit).

I know Android Typecasting is a bit more strict than for the PC/Web, but I'm at a loss as to why the above isn't working.

p.s - I tested the above code on android/iOS with basic cubes created in the editor, and the code works with those primitives.
