I'm planning to land the changes for <a href="https://github.com/apple/swift-evolution/blob/master/proposals/0055-optional-unsafe-pointers.md" class="">SE-0055: Making pointer nullability explicit</a> this afternoon in the Swift compiler; however, the corresponding diff for Foundation is fairly large (<a href="https://github.com/apple/swift-corelibs-foundation/pull/304" class="">PR #304</a>). Because of this, we've decided to hold off on migrating Foundation to the new model for UnsafePointer, so that it can be reviewed at leisure. This means that for a period of time, <b class="">swift-corelibs-foundation will not build against the 'master' branch of the compiler</b>. Instead, we're going to make a branch today that's passed all the CI checks, and use that for regression-testing (and building) Foundation for now.<div class=""><br class=""></div><div class="">Mishal, Jacob, or I will send a follow-up email once the compiler branch has been created, and another once CI has been updated.</div><div class=""><br class=""></div><div class="">Jordan<br class=""><div class=""><br class=""></div><div class=""><br class=""></div></div></body></html>
