Currently, my opinion is changed to the Xcode project is not completely able to deal with multiple platforms. Though it can display multiple platforms but only one platform can be chosen at one time to screen display by the SDKROOT setting. If you select iOS, it will use something like Debug-iphoneos for build product path. So all Mac OS X targets will be missing. If you choose Mac OS X, it will use something like Debug. So all iOS targets' products will be missing.

I think Xcode still have internal bug related this. It's long time to go to make Xcode to be stabilized.
