UnityEngine.Touch error

I have this script that is suppose to handle mobile touch input I found on forum but I keep getting the error message

error CS0030: Cannot convert type UnityEngine.Touch' to Touch’

  using UnityEngine;
    using System.Collections;
    using System.Collections.Generic;
    
    public class TouchInput : MonoBehaviour {
    
    	public LayerMask TouchInputMask;
    
    	private List<GameObject> touchList = new List<GameObject>();
    	private GameObject[] touchesOld;
    
    	public RaycastHit hit;
    
    
    	void Update () {        
    
    
    			if (Input.touchCount > 0){
    
    				touchesOld = new GameObject[touchList.Count];
    				touchList.CopyTo(touchesOld);
    				touchList.Clear();
    
    
    
    				foreach (Touch touch in Input.touches) {  //This is where the error is coming from.
    
    				Ray ray = camera.ScreenPointToRay(touch.position);
    				RaycastHit hit;
    
    			if(Physics.Raycast(ray,out hit,TouchInputMask)){
    
    				GameObject recipient = hit.transform.gameobject;
    				touchList.add(recipient);
    
    				if(touch.phase == TouchPhase.Began){
    					recipient.SendMessage("OnTouchDown",hit.point,SendMessageOptions.DontRequireReceiver);
    				}
    
    				if(touch.phase == TouchPhase.Ended){
    					recipient.SendMessage("OnTouchUp",hit.point,SendMessageOptions.DontRequireReceiver);
    				}
    
    				if(touch.phase == TouchPhase.Stationary){
    					recipient.SendMessage("OnTouchStay",hit.point,SendMessageOptions.DontRequireReceiver);
    				}
    
    				if(touch.phase == TouchPhase.Canceled){
    					recipient.SendMessage("OnTouchExit",hit.point,SendMessageOptions.DontRequireReceiver);
    				}
    
    			}
    		}
    
    		foreach (GameObject g in touchesOld){
    			if (!touchList.Contains(g)){
    				g.SendMessage("OnTouchExit",hit.point,SendMessageOptions.DontRequireReceiver);
    			}
    		}
    
    	}
    			}
    
    		
    }

try this

foreach (UnityEngine.Touch touch in Input.touches)

You must built that on android device
