Output of swift format --version is confusing

[jkmathew]

I am using Xcode 16 which comes with a bundled swift format. When I run swift format --version, it prints main.
Does this mean the swift format bundled with Xcode will always be updated with the latest main branch? Or the bundled version is the latest from the main branch at the time of Xcode release is created?

I tried installing swift-format with homebrew and swift-format --version prints the version correctly.

Unfortunately we've had to manually update the version number when cutting a release, and that can get overlooked easily. I know I've done it in the past.

IIRC, a recent change in SwiftPM has added a package API to query Git repository information and generate constants that we could reference from the --version handler instead. I would need to look further into it to see if that works as intended when a release is tagged and built.

I see there is already an automation implemented here
Tags containing proper versions like

swift-format/Sources/swift-format/PrintVersion.swift

Line 15 in 93ebb77

print("601.0.0-prerelease-2024-10-01")

I hope Xcode 16.1 release will have the proper version 🙂
