# removeObject(at:)

Removes a the object at the specified index from the mutable ordered set.

```
func removeObject(at idx: Int)
```

## Parameters

`idx`

The index of the object to remove from the mutable ordered set. The value must not exceed the bounds of the set.
  
  > Important:
  > Raises an ``doc://com.apple.foundation/documentation/Foundation/NSExceptionName/rangeException`` if index is beyond the end of the mutable ordered set.

## Discussion

To fill the gap, all elements beyond index are moved by subtracting 1 from their index.
