[swift-evolution] Dropping NS Prefix in Foundation

> It’s not a goal to rewrite Foundation from scratch in Swift. All Swift apps that are running out there today are in fact using a combination of Swift, Objective-C, C, C++, various flavors of assembly, and more. The goal is to present the existing API of Foundation in a way that fits in with the language today while allowing us to iteratively improve it over time.

Perhaps my concern is a higher level - I don’t understand where Foundation is envisioned going.

From my perspective, Foundation is highly coupled to Apple platforms and Objective-C on one side, and part of the Swift standard library on the other. Perhaps long-term Foundation should be split into two new things - a core library for cross-platform swift development, and the infrastructure for Objective-C interoperability on apple platforms only.
