Hi @dankinsoid! Thanks for the PR. Could you take some time to update its description with what it intends to fix, i.e. what the problem you were seeing was and how to reproduce it?

[dankinsoid]

@stephencelis done

[stephencelis]

@dankinsoid Sorry, can you also provide steps to reproduce and the environment you're in (macOS, targeted OS, Xcode, etc.)? Might be easy for me to figure out when I look into this but just in case it isn't. 😅

[dankinsoid]

@stephencelis I reproduce it on two computers, iMac M1 macOS Ventura 13.0 and macbook Intel macOS 12
Xcode 14.1, swift 5.7.1, just trying to build the package branch swift-5-7

[stephencelis]

Ah gotcha, I missed this was for the unreleased 5.7 branch. Will try to take a look soon, thanks!

[dankinsoid]

@stephencelis yes, I want to use swift-url-routing in VDFlow so I'm interested in 5.7 version

[stephencelis]

@dankinsoid Sorry this lingered. Did you find the updated swift-5-8 branch? That should be building well right now.

[dankinsoid]

@stephencelis yes now it builds, thank you
