I want to upgrade my Xcode 3.2.3 to Xcode 4.0 but I want to confirm one thing about my current project code. Will upgrading cause problems with my current code ? Can I still run the code made by Xcode 3.2.3 and run it and modify it with Xcode 4.0 ?
If y开发者_JAVA技巧ou have experience regarding this please let me know.
Xcode 4 uses the same project structure as Xcode 3. You can switch back and forth between them without any trouble.
