Raycast Ignores all layers instead of specified layer

Its certainly the raycast because when I remove the Layer Mask. the problem is fixed…

Layer 8 is to be ignored.

public RaycastHit2D hitInfo;                  
public float reachDistence = 3.5f;          
private Vector2 movingDirection;
int playerLayer = 1 << 4;  

    void Update () {
        if (Input.anyKey)
        {
            movingDirection = new Vector2 (Input.GetAxis("Horizontal"), Input.GetAxis("Vertical"));
      
            Debug.DrawRay(transform.position, movingDirection, Color.red);

            hitInfo = Physics2D.Raycast(transform.position, movingDirection, reachDistence, playerLayer);
            if (hitInfo)    //If raycast has hit a object
            {
                Debug.Log("Physical Hit!");
                Debug.Log(hitInfo.collider.name);
            }
        }
    }

int mask = Physics.DefaultRaycastLayers & ~(0x1 << 8); //Player layer is layer 8
hitInfo = Physics2D.Raycast(transform.position, movingDirection, reachDistence, mask);
