# subscript(_:)

Returns the object at the specified index.

```
subscript(idx: Int) -> Any { get }
```

## Parameters

`idx`

An index within the bounds of the array.

## Return Value

The object located at `idx`.

## Discussion

This method has the same behavior as the [`object(at:)`](/documentation/Foundation/NSArray/object(at:)) method.

If `idx` is beyond the end of the array (that is, if `idx` is greater than or equal to the value returned by `count`), an [`rangeException`](/documentation/Foundation/NSExceptionName/rangeException) is raised.

You shouldn’t need to call this method directly. Instead, this method is called when accessing an object by index using subscripting.

```objc
id value = array[3]; // equivalent to [array objectAtIndex:3]
```

## See Also

[`setObject:atIndexedSubscript:`](/documentation/Foundation/NSMutableArray/setObject:atIndexedSubscript:)

Replaces the object at the index with the new object, possibly adding the object.
