Thank you for the quick response, I could never had found that on my own!

This problem is solved, but now i've a bunch of errors that are too long to describe, so here is a print screen

 (mainly on semantic issues):

Thank you, it's working now!

I tried to compare with the Tutorials settings but they are so numerous that i certainly missed this part!

Again, thank you to answer question so quickly, even to XCode noobs ;-)
