Rename Encodable.CodingKeys?
The documentation on enumerations 1 clearly reads,
Give enumeration types singular rather than plural names, so that they read as self-evident:
var directionToHead = CompassPoint.west
It looks like CodingKeys is an exception to this. New adopters of Swift will encounter it and suppose that their own enumeration types should likewise have plural names.
The name CodingKey is already used as a protocol. We could rename either CodingKey or CodingKeys.

Swift 5.1.2 has been released and is available for download.
Along with an assortment of bug-fixes, Swift 5.1.2 contains an improved type-checking algorithm that has significant performance benefits on code using function builders (such as SwiftUI code).

All core libraries have been migrated to modern CMake
This is to announce that the last of the staging is now complete. All of the core libraries (libdispatch, foundation, XCTest) are now being built with CMake 3.15.1. This is largely transparent for most people (though a clean build won't hurt).
The biggest advantage that this brings is that the builds are much simpler, with largely a declaration of the sources and the libraries that they correspond to. ...

[Pre-Pitch] Runtime Type Guarantees
Motivation
There is always a tradeoff between safety and performance when writing reusable code. Low level code either has to make assumptions about the values being passed to it (e.g. a value is non-zero, or an array is non-empty) or it has to check those assumptions. When these functions call one another, but could also be called from the outside, you often find them repeatedly performing the same check.

Infer associated types as generic parameters more eagerly
Introduction
This proposal changes associated type inference behavior to short-circuit a large amount of inference work in the case where the conforming type defines a generic parameter with the same name as an associated type.This breaks source compatibility with certain valid programs; in Swift 5.1, it is possible for an associated type and a generic parameter with the same name to have different types. However, the name lookup behavior in this case was already very fragile.

Cross-Import Overlays
Say we have a pair of frameworks
NumericKitandFormatKitwhereNumericKitcovers numerical simulations andFormatKitcovers serialization and deserialization for a bunch of data formats. Ideally, a downstream project that depends on both of these frameworks would "automatically" get cross-cutting functionality. In this example, it could be something like serializing complex data using the HDF5 format (say).

[Returned for revision] SE-0272 Package Manager Binary Dependencies
The review for SE-0272 has concluded. We had a uniformly positive response to the idea of supporting binary dependencies in SwiftPM and the high-level design, but there are a number of concerns that came up during review.
