I imported two existing projects that were mostly recently built with XCode 5. However all I can do is Build them (And release only.) Run/Debug/Profile/Edit Configurations etc... are greyed out of the Run menu, and Project Settings is greyed out of the File menu. Command-; doesn't respond either. The activity strip at the bottom is still Scanning files to index as it has been for the past 3 hours, and in Activity monitor it's using 113-178% of CPU across 70 threads.
Any idea what to do?
