Swipe controls work on Android but not on iOS?

Hi Everyone,

So I got a program which move a player to three places and the user can change places by swiping left or right. The issue is that it works on Android phones but on iOS phones? Why is this?

Here is the code:

//---------------------Touch Inputs------------------------- private void touch_controls() { tap = swipe_left = swipe_right = false;

     //---------------mouse inputs-------------------
     if (Input.GetMouseButtonDown(0))
     {
         tap = true;
         is_dragging = true;
         start_touch = Input.mousePosition;
     }
     else if (Input.GetMouseButtonUp(0))
     {
         is_dragging = false;
         reset_movements();
     }


     //-------------mobile inputs--------------
     //get touch information
     if (Input.touches.Length > 0)
     {
         if(Input.touches[0].phase == TouchPhase.Began)
         {
             tap = true;
             is_dragging = true;
             start_touch = Input.touches[0].position;
         }
         else if(Input.touches[0].phase == TouchPhase.Ended || Input.touches[0].phase == TouchPhase.Canceled)
         {
             is_dragging = false;
             reset_movements();
         }
     }

     //Calculate the distance
     swipe_delta = Vector2.zero;
     if(is_dragging)
     {
         if(Input.touches.Length > 0)
         {
             swipe_delta = Input.touches[0].position - start_touch;
         }
         else if (Input.GetMouseButton(0))
         {
             swipe_delta = (Vector2)Input.mousePosition - start_touch;
         }
     }

     //the length of how long the swipe must be for player movement
     float swipe_length = 75;

     if(swipe_delta.magnitude > swipe_length)
     {
         //get direction
         float x = swipe_delta.x;
         float y = swipe_delta.y;

         //horizontal swipes
         if(Mathf.Abs(x) > Mathf.Abs(y))
         {
             // left or right swipe
             if(x < 0)
             {
                 //swipe left
                 swipe_left = true;
             }
             else
             {
                 //swipe right
                 swipe_right = true;
             }
         }

         //reset values
         reset_movements();
     }
 }

 private void reset_movements()
 {
     //reset position after swipe
     start_touch = swipe_delta = Vector2.zero;
     is_dragging = false;
 }

 public Vector2 get_swipe_delta()
 {
     return swipe_delta;
 }

 public bool get_swipe_left()
 {
     return swipe_left;
 }

 public bool get_swipe_right()
 {
     return swipe_right;
 }

 private void touch_movements()
 {
     //position for player
     float left_side = -game_controller.get_camera_width() / 2 + 1;
     float middle = 0;
     float right_side = game_controller.get_camera_width() / 2 - 1;

     //speed for movement
     float player_speed = 8f;

     //swipe left function
     if (get_swipe_left())
     {
         if (player.transform.position.x == right_side)
         {
             target_position = new Vector3(middle, player.transform.position.y, player.transform.position.z);
         }
         else if (player.transform.position.x == middle)
         {
             target_position = new Vector3(left_side, player.transform.position.y, player.transform.position.z);
         }
     }

     //swipe right function
     if (get_swipe_right())
     {
         if (player.transform.position.x == left_side)
         {
             target_position = new Vector3(middle, player.transform.position.y, player.transform.position.z);
         }
         else if (player.transform.position.x == middle)
         {
             target_position = new Vector3(right_side, player.transform.position.y, player.transform.position.z);
         }
     }

     player.transform.position = Vector3.MoveTowards(player.transform.position, target_position, player_speed * Time.deltaTime);
 }

Kind regards
