Using master branch of [swift-format](https://github.com/apple/swift-format) requires you to also use the `swift-DEVELOPMENT-SNAPSHOT-2019-09-26-a` toolchain. Where can I acquire it? I cannot seem to find it, and [trying to guess the url](https://swift.org/builds/development/xcode/swift-DEVELOPMENT-SNAPSHOT-2019-09-26-a/swift-DEVELOPMENT-SNAPSHOT-2019-09-26-osx.pkg) gives me a "Not Found" page

edit:  
🤦‍♂️ I forgot a second `-a-` when guessing the url

Hi @cukr, the snapshots are usually found at [this page](https://swift.org/download/#snapshots).

I couldn't find the mentioned snapshot in that page, however, I looked at the url signature of the other snapshots and guessed the url for the specific snapshot you're looking for, here it is:  
[https://swift.org/builds/development/xcode/swift-DEVELOPMENT-SNAPSHOT-2019-09-26-a/swift-DEVELOPMENT-SNAPSHOT-2019-09-26-a-osx.pkg](https://swift.org/builds/development/xcode/swift-DEVELOPMENT-SNAPSHOT-2019-09-26-a/swift-DEVELOPMENT-SNAPSHOT-2019-09-26-a-osx.pkg).

Hope this helps!

PS  
Just noticed your edit, well I hope it helps someone that might stumble upon this discussion 😊

We just merged a much needed update today that migrates swift-format to newer SwiftSyntax APIs that were refactored a while back. This also syncs the master branch up to a much more recent development snapshot, [swift-DEVELOPMENT-SNAPSHOT-2020-01-29-a](https://swift.org/builds/development/xcode/swift-DEVELOPMENT-SNAPSHOT-2020-01-29-a/swift-DEVELOPMENT-SNAPSHOT-2020-01-29-a-osx.pkg).
