Andreas,

The error you get about the wrong platform is due to the fact that by  
default the Debug build configuration just builds for the architecture  
on which you are compiling, whereas Release will build a universal  
binary.  If you haven't built all of the frameworks against which your  
application links as universal binaries, then you'll get this error.

You have two options:
1) Change your build settings so your Release build configuration does  
not build a universal binary.
2) Re-build all of your frameworks as universal binaries so your  
application can be built as a universal binary.

For option 1, you need to go to your Project's build settings  
(Project ... Edit Project Settings) and switch to the Release  
configuration.  Update the Architectures setting (it's the first one)  
so that it only lists your architecture.

Let me know if any issues come up.
