Unity 5 Movement swipe to left and right and up and down

Hello can someone make a t$$anonymous$$s script work with swipe like when you swipe to the side you move to the side and when you swipe up it jumps here is my script PlayerControl

 using UnityEngine;
 using System.Collections;
 
 public class PlayerControl : MonoBehaviour {
 
     CharacterController controller;
     bool isGrounded= false;
     public float speed = 6.0f;
     public float jumpSpeed = 8.0f;
     public float gravity = 20.0f;
     private Vector3 moveDirection = Vector3.zero;
 
     //start 
     void Start () {
         controller = GetComponent<CharacterController>();
     }
 
     // Update is called once per frame
     void Update (){
         if (controller.isGrounded) {
             GetComponent<Animation>().Play("run");            //play "run" animation if spacebar is not pressed
             moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, 0);  //get keyboard input to move in the horizontal direction
             moveDirection = transform.TransformDirection(moveDirection);  //apply t$$anonymous$$s direction to the character
             moveDirection *= speed;            //increase the speed of the movement by the factor "speed" 
 
             if (Input.GetButton ("Jump")) {          //play "Jump" animation if character is grounded and spacebar is pressed
                 GetComponent<Animation>().Stop("run");
                 GetComponent<Animation>().Play("jump_pose");
                 moveDirection.y = jumpSpeed;         //add the jump height to the character
             }
             if(controller.isGrounded)           //set the flag isGrounded to true if character is grounded
                 isGrounded = true;
         }
 
         moveDirection.y -= gravity * Time.deltaTime;       //Apply gravity  
         controller.Move(moveDirection * Time.deltaTime);      //Move the controller
     }
 
     //check if the character collects the powerups or the snags
     void OnTriggerEnter(Collider other)
     {
         if(other.gameObject.name == "Powerup(Clone)")
         {
             //do somet$$anonymous$$ng
         }
         else if(other.gameObject.name == "Obstacle(Clone)")
         {
             //do somet$$anonymous$$ng
         } 
         Destroy(other.gameObject);            //destroy the snag or powerup if colllected by the player
 
     }
 }
