Mobile Swipe Gesture to flick object in 3D space

Hi, I am using the following code in order to try and throw gameobjects based on swipe inputs on a touch screen. However, I am not sure how to make it easier to aim. In its current state, it works vaguely as expected, but the throws are seemingly random and I cannot get the aiming right. Basically I need it so that when you swipe on the screen, the object gets a force acted on it in 3D space accordingly (an example may be a game where you would flick a football into a goal)

 void Update () {
         if (Input.touchCount > 0)
     {
         Touch touch = Input.touches[0];
 
         switch (touch.phase)
         {
             case TouchPhase.Began:
                 startPos = touch.position;
                 break;
             case TouchPhase.Ended:
               
                 float swipeDistHorizontal = (new Vector3(touch.position.x, 0, 0) - new Vector3(startPos.x, 0, 0)).magnitude;
                     float swipeDistHorizontalActual = (new Vector3(touch.position.x, 0, 0).x - new Vector3(startPos.x, 0, 0).x);
                 float swipeDistVertical = (new Vector3(0, touch.position.y, 0) - new Vector3(0, startPos.y, 0)).magnitude;
                 if (swipeDistHorizontal > 2)
                 {
                     float swipeValue = Mathf.Sign(touch.position.x - startPos.x);
                     if (swipeValue > 0 && !isTouch)//to right swipe
                     {
                         isTouch = true;
                         //StartCoroutine(Right());
                         Debug.Log("RIGHT");
                     }
                     else if (swipeValue < 0 && !isTouch)//to left swipe
                     {
                         isTouch = true;
                         //(Left());
                             Debug.Log("LEFT");
                     }
                 }
 
                 //add swipe to up
                 if(swipeDistVertical > 2)
                 {
                     float swipeValue = Mathf.Sign(touch.position.y - startPos.y);
                     if(swipeValue > 0)
                     {
                         isTouch = true;
                             Debug.Log("UP");
                     }
                 }   
                 GameObject cheese = cheesePool.transform.GetChild(Random.Range(0, cheesePool.transform.childCount - 1)).gameObject;
                 cheese.transform.position = spawnPos;
                     cheese.AddComponent<Rigidbody>();
                     cheese.GetComponent<Rigidbody>().AddForce(new Vector3(swipeDistHorizontalActual, 0.45f * swipeDistVertical, swipeDistVertical) * force);
                     cheese.transform.SetParent(null);
                     isTouch = false;
                 break;
 //            case TouchPhase.Ended:
 //                //isSwipe = false;
 //                isTouch = false;
 //                break;
         }

The gameobjects I am throwing are the "cheese" objects which are loaded from a pool.

Any help is greatly appreciated, thanks.
