Swipe controls error "Cannot implicitly convert type 'UnityEngine.Touch' to 'Touch' "

I'm trying to make my character move up and down when the player swipes up and down on their mobile scree but I get the error in the title. Here's the code:`using UnityEngine; using System.Collections;

public class Touch : MonoBehaviour {

 public float minSwipeDistY;

 public float minSwipeDistX;

 private Vector2 startPos;

 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 swipeDistVertical = (new Vector3(0, touch.position.y, 0) - new Vector3(0, startPos.y, 0)).magnitude;

                 if (swipeDistVertical > minSwipeDistY) 
                     
                 {
                     
                     float swipeValue = Mathf.Sign(touch.position.y - startPos.y);
                     
                     if (swipeValue > 0)//up swipe

                         //Jump ();
                     
                     else if (swipeValue < 0)//down swipe

                         //Shrink ();
                     
                 }
                 
                     break;
         }
     }
 }

} `
