 Before embarking on a large amount of work to implement missing functionality, please double-check with the community on the [swift-corelibs-dev](https://lists.swift.org/mailman/listinfo/swift-corelibs-dev) mailing list. Someone may already be working in this area, and we want to avoid duplication of work.

 ## Portability
 
-This version of Foundation is designed to support the same API as the Foundation that ships with Apple operating systems. A key difference is that the distribution of Swift open source does not include the Objective-C runtime. This means that the source code of Foundation from OS X and iOS could not be simply reused on other platforms. However, we believe that the vast majority of the core API concepts presented in Foundation are themselves portable and are useful on all platforms.

 It is not a goal of this project to create new API that extends beyond the API provided on Apple operating systems, as that would hamper the goal of portability.
