how can i draw a sprite between 2 touch points with the direction of the sprite facing the direction of the swipe?

ie: draw an arrow sprite between touch began and touch move end with the arrow direction facing touch move end?

Something like this might do the trick:

using UnityEngine;
using System.Collections;

public class PointArrow : MonoBehaviour
{
    public GameObject arrow;

    private Vector2 start;

    void Update()
    {
        foreach (Touch t in Input.touches)
        {
            Vector2 pos = Camera.main.ScreenToWorldPoint(t.position);

            if (t.phase == TouchPhase.Began)
            {
                arrow.transform.position = start = pos;
            }

            if (t.phase == TouchPhase.Ended)
            {
                Vector2 dir = pos - start;

                arrow.transform.rotation =
                    Quaternion.Euler(0, 0, Mathf.Rad2Deg * Mathf.Atan2(dir.y, dir.x));
            }
        }
    }
}
