macOS 13/Xcode 14 requiring code signing of all apps even on x86

Hi all,
It’s probably too early to talk about this but I would like to share something 
I found playing with the newest beta OS.
When trying to get iTerm2 port to build on macOS 13, Xcode spits out error "An 
empty identity is not valid when signing a binary for the product type [type]”. 
Previously to avoid signing problems, I or someone else had the identity 
removed, effectively disabling code signing. This apparently no longer works, 
and I had to use the adhoc signing identity “-“ for it to build.
This could affect a number of ports that are using Xcode to build apps, so I 
figured people here should know.
