Start debugging with XCode


 Sorry for this, maybe, begginer level post!

I am trying to set my XCode to debug (for a school project) and it took me a ridicously amount a time to figure out how, but with no result.

I have found the tutorial which explains this : .

However,  after setting up Xcode, attaching to PluginHost and opening UI of my plug-in, an error appear saying :  "Choose a destination with a supported architecture in order to run on this system" (I have attached some screenshots).

I am running XCode 5.0.1, OSX 10.8.5 and JUCE 3.2.1.

The only way I could debug in XCode by now, was to attach to PluginHost and open UI (with no other customisations of Xcode build scheme). 

But, all I could see was the constructor values of myPlugin and that was not such a great help for me.

Maybe I miss something or don't know something yet, but any answer or documentation will be helpful (already searched on a few forums, including this one).

Thank you!
