Xcode built problem

I am having building Codea projects exported to Codea.

I create a brand new single view project in Xcode and it builds fine.
It builds, comes up in the simulator and all is good.

I create a new project in Codea, add no code to it, export it to Codea and the build just hangs.
It stops at:
Running 1 of 1 custom shell scripts

No matter how long I wait, it just stays at that point.
Anyone have any ideas or suggestions?
Thanks

OK, problem solved, … sort of.

It literally took over 15 minutes to build the first time.
The second time, it was less than 15 seconds.

Not sure what my Mac is up to,
Thanks
