# sort(_:context:)

Sorts the receiver in ascending order as defined by the comparison function `compare`.

```
func sort(_ compare: (Any, Any, UnsafeMutableRawPointer?) -> Int, context: UnsafeMutableRawPointer?)
```

## Parameters

`compare`

The comparison function to use to compare two elements at a time.

    The function’s parameters are two objects to compare and the context parameter,     `context`    . The function should return     `NSOrderedAscending`     if the first element is smaller than the second,     `NSOrderedDescending`     if the first element is larger than the second, and     `NSOrderedSame`     if the elements are equal.

`context`

The context argument to be passed to the compare function.

## Discussion

This approach allows the comparison to be based on some outside parameter, such as whether character sorting is case sensitive or case insensitive.

## See Also

[`-  sortedArrayUsingFunction:context:`](/documentation/Foundation/NSArray/sortedArray(_:context:))

Returns a new array that lists the receiving array’s elements in ascending order as defined by the comparison function `comparator`.
