So, I opened a xib file from an older project and it caused a crash. That’s not the issue. The issue is that now when I restart Xcode, it tries to open all previously opened projects (and files) and the crash re-occurs. Where does Xcode store the list of previously open files, and how can I get it to start ‘clean’ without any open projects?
Update: As a note – this is the latest version of Xcode 4.2 on Lion.
Press option+Shift when clicking on the Xcode icon in the dock. Xcode then starts without opening previously used projects. This is related to version Version 4.5.2 (4G2008a) but I am almost sure that I used it in older versions as well.
