# xpc_array_set_value(_:_:_:)

Inserts the specified object into the array at the specified index.

```
func xpc_array_set_value(_ xarray: xpc_object_t, _ index: Int, _ value: xpc_object_t)
```

## Parameters

`xarray`

The array object which is to be manipulated.

`index`

The index at which to insert the value. This value must lie within the index space of the array (0 to N-1 inclusive, where N is the count of the array). If the index is outside that range, the behavior is undefined.

`value`

The object to insert. This value is retained by the array and cannot be NULL. If there is already a value at the specified index, it is released, and the new value is inserted in its place.
