# NSIntersectionRange(_:_:)

Returns the intersection of the specified ranges.

## Declaration

```swift
func NSIntersectionRange(_ range1: NSRange, _ range2: NSRange) -> NSRange
```

## Return Value

Return Value A range describing the intersection of range1 and range2—that is, a range containing the indices that exist in both ranges.

## Discussion

Discussion If the returned range’s length field is 0, then the two ranges don’t intersect, and the value of the location field is undefined.
