I'm kind of new to this, and I downloaded Xcode today, so I have 6.3.2. I can edit my preferences and leave it open on the "Welcome to Xcode" page for as long as I want, but if I try to open a new project, it tells me that "Xcode quit unexpectedly. Click Reopen to open the application again. Click Report to see more detailed information and send a report to Apple." I can open a playground or workspace and it's fine, but not a project. I am running OS X 10.10.3. Please help me fix this!
