This is great news.

However, I wish the mac release was available as independent binaries without having to come along with Xcode.

The Command Line Tools include the Swift compiler without needing Xcode installed. Open up a terminal and type “swift” to enter the REPL or “swiftc” to compile a Swift File. SPM is included too.

If they’re not already installed, running one of those commands will prompt you to install them.

If I already have swift-3 and Xcode 8, how do I install only swift-4?

You can download a toolchain snapshot from here. There's a swift-4.0-branch download if you scroll a bit.

Keep in mind that binaries built with the toolchain snapshots cannot be submitted to the App Store. You need an Xcode release for that.

I received a CLT update today, it brought swift 4 with it.

Do you have homebrew installed? If so...

    brew install swiftenv
