Erroneous fix for NSIntersectionRect

[J-rg]

New Issue Checklist

• Updated SwiftLint to the latest version

Describe the bug

When using the legacy_nsgeometry_functions rule, SwiftLint replaces NSIntersectionRect(rect1, rect2) with rect1.intersect(rect2). CGRect does not have an intersect(_:) method, the correct method name would be intersection(_:), however, if two rectangles don’t intersect, the intersection(_:) method produces CGRect.null, while NSIntersectionRect(_:_:) produces CGRect.zero, so replacing it might silently break the code.

Environment

• SwiftLint version? 0.43.1
• Installation method used? Homebrew
• Which Xcode version are you using? Xcode 12.5.1 (12E507)
• Do you have a sample that shows the issue? echo "NSIntersectionRect(rect1, rect2)" | swiftlint lint --no-cache --use-stdin --enable-all-rules
