Question Issue with looping over list with foreach

I'm trying to create a grapple sort of system and when I'm trying to find the nearest object, it returns this error:

Code (CSharp):

1. NullReferenceException: Object reference not set to an instance of an object
2. Grappler.<Update>g__FindClosestObject|5_0 (System.Single range) (at Assets/Scripts/Grappler.cs:80)
3. Grappler.Update () (at Assets/Scripts/Grappler.cs:27)
4.  

This is the code in question

Code (CSharp):

1.             GameObject FindClosestObject(float range)
2.             {
3.                 GameObject[] objects = GameObject.FindGameObjectsWithTag("Object");
4.  
5.                 GameObject closest = null;
6.                
7.  
8.                 foreach(GameObject i in objects)
9.                 {
10.                     float distance = Vector3.Distance(transform.position, i.transform.position);
11.  
12.                     float closestDistance = Vector3.Distance(transform.position, closest.transform.position);
13.  
14.                     if (distance <= closestDistance)
15.                     {
16.                         closest = i;
17.                     }
18.  
19.                 }
20.                 return closest;
21.             }

 

closest is null the first iteration.

 

Sorry, I thought this was a general 2D forum, my bad.

 

Thanks, fixed it
