Does reinstalling a new version of Xcode automatically overwrite the old?

Does reinstalling a new version of Xcode automatically overwrite the old?

e.g. I had xcode 3.2.5 and I downloaded and installed Xcode 3.2.6 (including ios). Does the install overwrite and get rid of all the xcode 3.2.5 data (assuming it doesn't use any of it)? Thanks!

Solution

  • Yes and no. It will overwrite files in /Developer/usr, /Developer/Tools, /Developer/Library, etc, but if a file already exists that the new Xcode install does not have an upgrade for, the installer wont touch it if it doesn't have to. Personally, I have found that the best way to upgrade Xcode is the following:

    1. Backup the working /Developer directory (where the "old" Xcode is installed)

      [ 15:30 jon@MacBookPro / ]$ sudo mv /Developer /Developer-3.2.5

    2. Run the "new" Xcode installer using the default install location (/Developer).

    This way you have everything from both and can merge the files you need.
