We found a bit of a footgun in Swift with non-escaping closures and Objective-C interoperability. It's got me worried, and I'd like to hear opinions on our options: https://forums.swift.org/t/implicit-escaping-of-closures-via-objective-c/12025

Finding it hard to keep up with all the changes in #swiftlang? I made a new site just for you: https://www.whatsnewinswift.com https://twitter.com/twostraws/status/988499714835451905/photo/1

Tensor flow docs: https://github.com/tensorflow/swift

Specifically in the Swift for TensorFlow docs, there's the "Swift for TensorFlow Design Overview" section that IMO is worth specifically calling out: https://github.com/tensorflow/swift/blob/master/docs/DesignOverview.md

Really excited about this change: https://github.com/apple/swift/pull/16249

This lays the groundwork for finally eliminating SubstitutionList, the old representation for a mapping of generic parameters to concrete types

SubstitutionList is really just a typedef I added for ArrayRef, a problematic representation that does no information hiding and leaves memory management to the user

I had no idea, but it turns out that exhausiveness checking for switch statements is a really hard problem. We’ve made huge strides in correctness recently thanks to @CodaFi_, and now a team member is working on performance: https://github.com/apple/swift/pull/16300
