Correct? I guess that decision was made so that Swift apps in production built on Foundation don’t break when recompiled under Swift 3? Is it worth converging the names of the module so its the same on all platforms? Isn’t it bad if portable code was doomed to have #if os() for all Foundation imports? If we do rename it, do we rename it to SwiftFoundation on Linux or do we rename it to Foundation on OS X (which would require renaming the Objective-C Foundation to something else and write a migration)?<div class=""><br class=""><div class=""><blockquote type="cite" class=""><div class="">On 14 May 2016, at 00:19, David Hart via swift-corelibs-dev <<a href="mailto:swift-corelibs-dev@swift.org" class="">swift-corelibs-dev@swift.org</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta http-equiv="Content-Type" content="text/html charset=utf-8" class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><br class=""><div class=""><blockquote type="cite" class=""><div class="">On 13 May 2016, at 21:50, Tony Parker <<a href="mailto:anthony.parker@apple.com" class="">anthony.parker@apple.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><span style="font-family: Helvetica; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; float: none; display: inline !important;" class="">Technically, swift-corelibs-foundation is only part of the distribution on Linux.
