There is a new XCode update that ships Swift 5.1.3, which isn't available on swift.org yet.
This has happened before, (e.g. Swift 4.2.1, Swift 5.1.2). Every time this happens, it causes confusion and issues on my team because this breaks things like swiftenv and in general we would like everyone to run the same version as our docker images to minimise "works on my machine" issues.
Is it possible that Swift releases could be coordinated a bit more in the future?
