Upgrading Xcode issue

Question

I am currently working with Xcode 4.5.2 and I'd like to upgrade it to version 4.6. Will installing the new version completely replace the previous one? If so, is it possible to just "extend" your current version and keep the SDKs you already have? I wouldn't like to lose the compatibility with my current projects...

Thanks!

Answer 1

If you download from the developer web site rather than the app store you can have multiple versions of Xcode installed at the same time. At one point I had 4 or 5 versions.

"Will installing the new version completely replace the previous one? If so, is it possible to just "extend" your current version and keep the SDKs you already have?"

It is possible to install them side by side which allows you to start picking up newer versions as early as preview while being able to fallback to the stable version you've been working with. I roll between versions in parallel. Remember that developer tools have bugs too :)

Go to Applications and rename Xcode to Xcode45. Login to your developer account at apple, look under it for download older versions (which actually has newest version) and download the Xcode dmg for 4.6. Run it and drag to Applications.

Xcode 4.6.x supports iOS 4.3 through 6.1. Xcode 4.5.x supports iOS 4.3 through 6.0. Upgrading to 4.6 is not going to result in you losing any compatibility.
