Touch or swipe on certain location.

Hi. I'm making a 2d game in Unity with C#. I have the code for touch and swipe, but how can I make it so that something activates only when for example I swipe on a certain object?

1. foreach (var T in Input.touches)
2. {
3. var P = T.position;
4. if (T.phase == TouchPhase.Began && SwipeID == -1)
5. {
6. SwipeID = T.fingerId;
7. StartPos = P;
8. }
9. else if (T.fingerId == SwipeID)
10. {
11. var delta = P - StartPos;
12. if (T.phase == TouchPhase.Moved && delta.magnitude > minMovement)
13. {
14. SwipeID = -1;
15. if (Mathf.Abs(delta.x) > Mathf.Abs(delta.y))
16. {
17. if (delta.x > 0){
18. //code for swipe right
19. }
20. else if (delta.x < 0){
21. //code for swipe left
22. }
23. }
24. else
25. {
26. if (delta.y > 0){
27. //code for swipe up
28. }
29. else if (delta.y < 0){
30. //code for swipe down
31. }
32. }
33. }
34. else if (T.phase == TouchPhase.Canceled || T.phase == TouchPhase.Ended)
35. {
36. SwipeID = -1;
37. //code for tap
38. }
39. }
40. 
    
41. }
