2d swipe control not working.

Hey, I've been making a game and the last thing I needed to do was the swipe controls, I thought it was going to be easy because unity will have something implemented for us, but no, It is way harder than I thought so I had to follow a tutorial. what ended up happening is that my code isn't working, but I know the tutorial is good just that there is a problem in the code I wrote from the video (the video didn't have a copy of the code linked). What my code looks like now:

 private bool tap, swipeLeft, swipeRight, swipeUp, swipeDown, isDraging;
     private Vector2 startTouch, swipeDelta;
     private float moveSpeed = 1.5f;
 
     private void Update()
     {
         tap = swipeLeft = swipeRight = swipeUp = swipeDown = isDraging = false;
 
         
 
 
         #region Standalone Input 
         //click
         if (Input.GetMouseButtonDown(0))
         {
             tap = true;
             isDraging = true;
             startTouch = Input.mousePosition;
         }
         //release
         else if (Input.GetMouseButtonUp(0))
         {
             isDraging = false;
             Reset();
         }
 
 
 
         #endregion
 
         #region Moblie Inputs
         if(Input.touches.Length > 0)
         {
             if(Input.touches[0].phase == TouchPhase.Began)
             {
                 isDraging = true;
                 tap = true;
                 startTouch = Input.touches[0].position;
             }
             else if(Input.touches[0].phase == TouchPhase.Ended || Input.touches[0].phase == TouchPhase.Canceled)
             {
                 isDraging = false;
                 Reset();
             }
 
         }
 
 
         #endregion
 
         #region Swipe Check
         swipeDelta = Vector2.zero;
         if (isDraging)
         {
             if (Input.touches.Length > 0)
             {
                 swipeDelta = Input.touches[0].position - startTouch;
             }
             else if (Input.GetMouseButton(0))
             {
                 swipeDelta = new Vector2(Input.mousePosition.x, Input.mousePosition.y) - startTouch;
             }
         }
         Debug.Log(swipeDelta);
         if (swipeDelta.magnitude > 125)
         {
             //which direction are we swiping in
             float x = swipeDelta.x;
             float y = swipeDelta.y;
             if(Mathf.Abs(x) > Mathf.Abs(y))
             {
                 //left or right
                 if(x < 0)
                 {
                     swipeLeft = true;
                 }
                 else
                 {
                     swipeRight = true;
                 }
 
             }
             else
             {
                 //up or down
                 if(y < 0)
                 {
                     swipeDown = true;
                 }
                 else
                 {
                     swipeUp = true;
                 }
             }
 
 
             Reset();
         }
         #endregion

the swipeDelta is always 0.0, 0.0. The startTouch is working fine and showing the position of the click. I have no idea what could be wrong here, I've checked the code a few times now, haven't found anything suspicious yet.
