Xcode v3 - Xcode v4

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 c开发者_JAVA技巧ompatability faults with my projects.

As far as I have tried, there are no compatibility issues.. there is a chance that you might find a lot of memory issues/ warnings when u run/ analyze your code in xcode 4.. I dont know why that happens though... but other than that, your projects would run just fine with xcode 4.. and also, it is said that you can have both xcode 4 and xcode 3 installed at the same time without any problems...

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.
