Arduino on Xcode Project — Official Thread

ScottG:
Could the space between "Arduino" and "Sketches" be causing a problem?

Yes, I think so, as the tools used in the makefiles doesn't like spaces in folders and files names.

ScottG:
Can you make the uncompressed version available somewhere else, like slideshare.net?

Thank you for pointing me at slideshare.net. See http://us.slideshare.net/rei_vilo/embed-xcode-usermanual

I'm also considering another solution, publishing an ebook.
