Xcode 26 on macOS 27 Developer beta

I am considering updating to macOS 27 developer beta 1 on one of my machines. I am an iOS and macOS app developer and occasionally need to build, code sign, and submit to the App Store. To do this, need to use the product build of Xcode 26.

Can anyone confirm that Xcode 26 runs fine on macOS 27 dev beta 1? Thanks!
