2D raycast not working

Hello everyone!

So I have this piece of code:

     void MoveUp ()
     {
         Vector3 direction = Vector3.up;
         RaycastHit2D hit = Physics2D.Raycast(transform.position, Vector2.up, distance, 8);
         if (hit)
         {
             if (hit.transform.tag == "Wall")
             {
                 WallInFront();
             }
             else if (hit.transform.tag == "Enemy")
             {
                 Attack();
             }
         }
         else
         {
             if(move == false)
             {
                 // set position to move
                 desiredPosition += direction;
                 move = true;
             }
         }
     }

basically this piece of code gets executed when I swipe (this code is for swipe up, there's code for down left and right that are the same except for "Vector2/3.up"

what I want is to raycast and see what the raycast hitted, if it was a wall, do soemthing, if theres nothing in front, move

I cant seem to make this work.
