How easily does Xcode 4 open up and control Xcode 3 projects?
Has anyone had compatability trouble with this yet, I don't want to install a new version to then find compatability faults with my projects.
I have had no problems opening Xcode 3 projects in Xcode 4 (and I no longer have Xcode 3 installed). The actual project control files in Xcode 4 are 3.2 formatted, and Xcode 4 adds new files for its information. I used to go back to Xcode 3 for deployments until the GM was released without issues.
