    I have one book I am reading that uses Xcode 3 and I have looking at some Lynda.com videos that are explain things well but it is done in Xcode 4.

    Can I install 4 without erasing 3?

    If you install XCode 4 via the Mac App Store, you'll end up with XCode 4 in /Developer and XCode 3 in /Developer.old (I think it's called that, if not it's something similar anyway).

    Mutliple Versions

    You can also install any new version of Xcode into whatever folder you want. That way you can have as many versions of Xcode as you want. Just be sure to start the version that you want to use.

    To install into a unique folder, simply specify that folder during the install process.

    For example, I have about five or six versions of Xcode installed in these folders:
    Developer 2010_07_15 Xcode 3.2.3 SDK 4.0.1
    Developer 2010_11_22 Xcode 3.2.5 SDK 4.2
    Developer 2011_03_03 Xcode 4 GM 2 SDK 4.3
    Developer 2011_03_09 Xcode 4.0.0 SDK 4.3
    Developer 2011_03_24 Xcode 4.0.1 SDK 4.3
    Developer 2011_05_01 Xcode 4.0.2 SDK 4.3
