# replaceObjects(at:with:)

Replaces the objects in the receiving array at locations specified with the objects from a given array.

```
func replaceObjects(at indexes: IndexSet, with objects: [Any])
```

## Parameters

`indexes`

The indexes of the objects to be replaced.

`objects`

The objects with which to replace the objects in the receiving array at the indexes specified by `indexes`. The count of locations in `indexes` must equal the count of `objects`.

## Discussion

The indexes in `indexes` are used in the same order as the objects in `objects`.

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

## See Also

[`removeObject(at:)`](/documentation/Foundation/NSMutableArray/removeObject(at:))

[`insert(_:at:)`](/documentation/Foundation/NSMutableArray/insert(_:at:)-5dbx5)

Inserts a given object into the array’s contents at a given index.
