[swift-users] experimental conditional conformances flag

[Matt Whiteside]

Hello Swift Users,

[This is a resend with smaller attachment]  Has anyone had luck passing the new '-enable-experimental-conditional-conformances' flag to Xcode?  It works when I run swift from the command line, with the Dec. 5th snapshot toolchain, but not Xcode.  I have tried whats in the screenshot below as well as adding -Xfrontend, but I’m still getting the usual ‘extension of protocol cannot have an inheritance clause’ error:

Thanks for any suggestions on this,

Matt
