I removed library lstdc++6.0.9.dylib from the project because it is not required and Xcode 10.1 won't let me compile.
Likewise, I leave Valid Architectures to be blank. When I try to run with the simulator, I get the permission error.
I have no executable prefix or extension, so my EXECUTABLE_NAME is the same as the PRODUCT_NAME. The code base has remained the same and I have no issue compiling, running in simulator, and creating a release with Xcode 8 or 9.
It would be very helpful if Xcode 10 can offer some hints as to what may be some causes for the permission message.
Please advise. Than you.
