OK, after lots of desperate attempts to make Connection Kit work, I've finally made it to create a project get to compile - yay!. Oh, wait, I didn't say it actually runs. It just compiled without any error - yay, again.
But now I guess I have to deal with linking issues.

Any idea what this means guys? What am I supposed to do?
The accepted answer here (Codesign of Dropbox API fails in Xcode 4.6.3: "code object is not signed at all") basically suggests using the --deep signing flag. But neither this seems to be supported in Xcode6+, nor does it work for me (the exact same errors are being produced).
