I am a learner about swift compiler.
I usually use $ utils/build-script --xcode --debug to build compiler.
And I use 2 ways to trace compiler internal execution.
First is open Xcode and set Launch = automatically in scheme for Run, and input Cmd + R to start compiler.
Second is set Launch = Wait for executable to be launched, input Cmd + R to wait starting compiler process, and type $ swift in terminal with $PATH including build product location.
It works good until now.
After I upgraded macOS to Mojave, second style does not work at all.
For example when I type $ swift --version, compiler immediately prints
$ swift --version
Swift version 5.0-dev (LLVM cbe8d5e28f, Clang 3452631569, Swift 2ef35ac80e)
Target: x86_64-apple-darwin18.2.0
xcode prints Message from debugger: unable to attach, and finish debugging.
I have gotten no information about fight to this from 3 weeks ago.
Please help me.
It's also possible that upgrading to Mojave reset the "developer mode" setting on the machine, which you can check by running DevToolsSecurity -status.
$ DevToolsSecurity -status -verbose
Getting rights definition for: system.privilege.taskport.debug
Current rights definition dictionary:
"(null)" : 1
"(null)" : "(null)"

"(null)" : 0
"(null)" : 541783963
"(null)" : "(null)"
"(null)" : { "(null)", "(null)", "(null)" }
Developer mode is currently enabled.
I have two mac and both have this issue.
One is private machine at home.
Another is work machine at office.
System management is independent.
OS and Xcode versions are same.
I tried to completely reinstall Xcode and all packages from homebrew.
I removed all sources of swift compiler.
And checkout and build from clean state.
But issue happened.
Is anyone who face same issue?
I think it is common problem in Mojave.
Today suddenly issue is resolved.
I used latest master.

[CSFix] Call a function/member which is incorrectly used as a property
One need to do is set Debug Process as to root.
I tested root setting already before.
So some changes about xcodeproj made by cmake in recent may resolve issue.
