So I saw this post: http://mobiledevelopertips.com/xcode/download-and-install-older-versions-of-xcode-xcode-previous-releases.html

(new location: at iosdevelopertips.com)

about downloading older versions of Xcode. Up to now, I have always just downloaded the newest version of Xcode from the App Store and let it do its thing. Recently on one computer that has Xcode 4.5 installed on it, I noticed that if I create a new project, I only get the iOS 6.0 simulators, not the 5.0 or 5.1.

  1. My first question is, do I need older versions of Xcode to build apps for older OS (e.g. iOS 4, iOS 5.0, 5.1, etc)?

  2. If so, what’s the best way of installing these older versions of Xcode. I see that they have the command line tools to download as well. I’m not sure how all that stuff works.

  3. What’s the best way to update to the latest Xcode but keeping the old Xcode around? On a different machine that had Xcode 4.4.1 installed, I thought I could download Xcode 4.5 from the ADC website and install it. I downloaded it, double-clicked on the .dmg, then double-clicked on the Xcode file. This then installed Xcode 4.5 without asking me where I wanted it installed so I could keep the older version of Xcode (assuming that I need it as stated in my 1st question).

Thanks!

    I noticed that if I create a new project, I only get the iOS 6.0 simulators, not the 5.0 or 5.1.

    Choose your project target and in Summary tab, set the lowest Deployment Target for your app (I think the default value is 6.0 in Xcode 4.5).

    My first question is, do I need older versions of Xcode to build apps for older OS (e.g. iOS 4, iOS 5.0, 5.1, etc)?

    If you’ve updated from old version of Xcode, you can use the old SDK & simulator in new version.

    If so, what’s the best way of installing these older versions of Xcode. I see that they have the command line tools to download as well. I’m not sure how all that stuff works.

    Actually, different versions of Xcode can stay happily with each other. It is a App Bundle right now.

    third question

    Just drag the new version of Xcode to Application folder. That’s done. 🙂
