Xcode 5: how to enable "reopen last projects/windows"?

Question

I'm stumped. Xcode 5 - the final and public release only - will no longer automatically re-open the previously open projects when restarting Xcode. This feature always used to work, up to and including the Xcode 5 GM seed.

I can't find anything regarding "open last windows" or similar in System Preferences. It used to be on the General page. This is all there is in my version:

Does anyone know how to re-enable this feature, and can you confirm that it is gone? Or do I have a broken Xcode?

Answer 1

This is actually an os x feature. Under "System Preferences" and then "General", there is a checkbox that says "Close windows when quitting an application". This needs to be unchecked to reopen windows. This is what I had to do to get the opposite effect of what you want and can confirm this works.

In previous os x 10.7- it's ""Restore windows when quitting and re-opening apps", and needs to be checked to work.
