# removeObjects(at:)

Removes the objects at the specified indexes from the array.

```
func removeObjects(at indexes: IndexSet)
```

## Parameters

`indexes`

The indexes of the objects to remove from the array. The locations specified by `indexes` must lie within the bounds of the array.

## Discussion

This method is similar to [`removeObject(at:)`](/documentation/Foundation/NSMutableArray/removeObject(at:)), but allows you to efficiently remove multiple objects with a single operation. `indexes` specifies the locations of objects to be removed given the state of the array when the method is invoked, as illustrated in the following example:

```objc
NSMutableArray *array = [NSMutableArray arrayWithObjects: @"one", @"a", @"two", @"b", @"three", @"four", nil];
NSMutableIndexSet *indexes = [NSMutableIndexSet indexSetWithIndex:1];
[indexes addIndex:3];
[array removeObjectsAtIndexes:indexes];
NSLog(@"array: %@", array);
 
// Output: array: (one, two, three, four)
```

If `indexes` is `nil`, this method raises an exception.

[`-  initWithCapacity:`](/documentation/Foundation/NSMutableArray/init(capacity:))

Returns an array, initialized with enough memory to initially hold a given number of objects.
