Can you install both Xcode 3 and Xcode 4 preview 6?

Question

Is it possible to have both Xcode 3 and Xcode 4 on the same OS instance? Is it possible to write production code in Xcode 4 and then compile it for app store in Xcode 3 ? (From practical point of view)

Answer 1

You can install XCode into any folder, you don't have to use the default. Mark is right, don't upgrade the Unix package. I make a Beta folder and install the betas into that folder.

Answer 2

Well yes and no. :)

As of today with Xcode 4 GM seed, IF YOU USE THE DEFAULT LOCATION, it looks like Xcode 4 will now overwrite your /Developer and replace your Xcode 3.x. I think this is fairly new, as I have installed several of the earlier betas and have not had this happen.

So, as of now, I am a happy Xcode 4 user! <:/

Answer 3

You can install both Xcode 3 and 4 at the same time: Xcode 4 is installed into /Xcode4 while Xcode 3 is installed into the usual /Developer .

However, be advised that if you upgrade the UNIX development package, it will replace the Xcode 3 and stock Mac OS X versions of certain command line tools with the Xcode 4 versions.

For the most part, you'll need to use Xcode 3 for any code heading to the app store.
