Hello,

The NS prefix from NSRegularExpression seems to have been dropped only in open source Foundation. On Darwin the class is still called NSRegularExpression.

https://github.com/apple/swift-corelibs-foundation/blob/master/Foundation/NSRegularExpression.swift#L30

I went through the Drop NS prefix proposal but couldn't relate this to any of the rules mentioned there (except for a possibility that we will have a RegularExpression value type in future only on Darwin!)

Is there any particular reason for this difference?

Thanks in advance!

Hi Pushkar,

We decided to keep the NS on NSRegularExpression because we know that a strong goal for the Swift language is to have built-in support for regex. We wanted to be cautious about taking the name without knowing more about how that feature would shake out.

We should get a JIRA filed or a PR up to put the NS back for the class name in swift-corelibs-foundation.

Thanks,
- Tony

Thanks for the clarification, Tony. I've created a PR.
