[Accepted] SE-0270: Add Collection Operations on Noncontiguous Elements

The review of SE-0270 spanned three separate review periods, from November 11th, 2019, to January 28th, 2020. The latest round of review is here.

Community feedback was highly positive on adding this feature in some form, but many details of the design were heavily debated. Reflecting on that feedback, the authors revised the proposal several times, trimming some controversial features and renaming others. Feedback on the third review suggests that, while many community members are now satisfied with the proposal, others remain concerned with some aspects of the current design. In the opinion of the Core Team, the remaining controversies do not justify returning the proposal for further review or revision; a decision just needs to be made.

Do you plan on writing this issue, Kristaps?

@BasThomas yep as we agreed

Ah, I understood I do two, you do one. Just did one. But go for it :)

Dodged an ABI bullet here. Underscored keyword was broken... but thankfully the broken case wasn’t exercised in the standard library https://github.com/apple/swift/pull/29579

Swift Configuration Library - swiftbox-config

Swiftbox-config is type-safe configuration library for Swift projects. SwiftBox Configuration allows to pass type-safe configuration such as command line, environment variables and external providers (e.g Vault) by declaring one simple struct. Configuration can be inherited from multiple sources simultaneously.

Hei @irshadpc for your contributions :)

I think SwiftUI and DispatchQueue we will leave out from this newsletter as this is soley about Swift language and open source aspects. Both of those technologies are available only for macOS and iOS type platforms, not in Linux.

Extensions should inherit availability of thing they are extending

I'm probably being dumb here, but it seems to me that the extension clause could (and should) safely have an implicit @available(iOS 13.0, *) added to it - in the absence of an explicit one - given that the thing that it is extending has one.

Really cool WIP from a teammate Tim here: https://github.com/apple/swift/pull/29658

Swift’s runtime casting infrastructure has been… “scary and organic” I guess? For quite a while. This rewrites it to be properly structured, and cleans up a ton of edge case behavior in the process.

@gottesmang We also put a lot of work into reducing code size and memory usage. Swift 5.2 binaries ought to be noticeably smaller, and use less memory when running on macOS 10.15.4, iOS 13.4, and friends
