# CFArraySortValues(_:_:_:_:) Sorts the values in an array using a given comparison function. ``` func CFArraySortValues(_ theArray: CFMutableArray!, _ range: CFRange, _ comparator: CFComparatorFunction!, _ context: UnsafeMutableRawPointer!) ``` ## Parameters `theArray` The array whose values are sorted. `range` The range of values within `theArray` to sort. The range location or end point (defined by the location plus length minus 1) must not lie outside the index space of `theArray` (`0` to `N-1` inclusive, where `N` is the count of `theArray`). The range length must not be negative. The range may be empty (length 0). `comparator` The function with the comparator function type signature that is used in the sort operation to compare the values in `theArray`. If this parameter is not a pointer to a function of the correct prototype, the behavior is undefined. If there are values in `theArray` that the `comparator` function does not expect or cannot properly compare, the behavior is undefined. The values in the range are sorted from least to greatest according to this function. `context` A pointer-sized program-defined value, which is passed as the third parameter to the `comparator` function, but is otherwise unused by this function. If the context is not what is expected by the `comparator` function, the behavior is undefined. --- Copyright © 2026 Apple Inc.
