using UnityEngine;
using System.Collections;

public class Bomb : MonoBehaviour {
	
	// Update is called once per frame
	void Update () {

		void OnTriggerEnter2D (Collider2D other)
		{
			Destroy(other.gameObject);
		}
	
	}
}

This is my code. What’s causing the error listed in the title?

You put the whole OnTriggerEnter2D method inside Update. It’s supposed to look like this:

using System.Collections;

public class Bomb : MonoBehaviour
{
   void Update ()
   {
   }

   void OnTriggerEnter2D (Collider2D other)
   {
       Destroy(other.gameObject);
   }
}

You don’t have to put the void OnTriggerEnter2D inside the update function.
See documentation for example Unity - Scripting API: MonoBehaviour.OnTriggerEnter2D(Collider2D)
