# CFArrayExchangeValuesAtIndices(_:_:_:)

Exchanges the values at two indices of an array.

## Declaration

```swift
func CFArrayExchangeValuesAtIndices(_ theArray: CFMutableArray!, _ idx1: CFIndex, _ idx2: CFIndex)
```

## Parameters

- `theArray`: The array that contains the values to be swapped.
- `idx1`: The index of the value to swap with the value at idx2. The index must not exceed the index space of theArray (0 to N-1 inclusive, where N is the count of theArray before the operation).
- `idx2`: The index of the value to swap with the value at idx1. The index must not exceed the index space of theArray (0 to N-1 inclusive, where N is the count of theArray before the operation).
