Newbie question I know... But can I build apps for Snow Leopard using the Mountain Lion Version of Xcode 4.4?
Yes, you can. You can always build programs with an intended target version of less than the current version (as long as that older version is still supported).

Is it possible to run MacRuby with XCode 3?
It is not possible for me to upgrade to XCode 4.2 because I am running Snow Leopard and have a machine that will not upgrade to Mountain Lion and Apple has pulled Lion from the App Store. I know you can download XCode 4.2 with a Apple Dev Account ($100 per year) but I am looking for a free solution.
Maybe there is an older version on MacRuby that can be installed with XCode 3? If you know which version, I would be interested if the installation instructions differ from that of XCode 4.2
Try looking here for previous versions of MacRuby.
I want to say that version 0.10 was compatible with Snow Leopard, but I'm not certain.
I need to develop a GUI for my MonoMac application. Which Xcode shall I use for cocoa development?
I am using Mono 3.0 and MAC OX Lion 10.8 in VMware on Windows 7 PC.
I'm guessing that you mean MonoDevelop 3.0.x and not Mono 3.0 (they are different things).
If that is the case, any Xcode from 4.2 or newer should work (older versions might work, but have not been tested).
I would suggest that you go with 4.4 or 4.5 as you'll need those if you plan to submit to the AppStore for Mountain Lion.
What version of Xcode should I use?
I tried installing 4.2 but got this cryptic error message
If i wasn't so annoyed I'd find this funny
Is there any reason you're still on OS X 10.7.2? If you can, update your Mac to 10.7.4. As for Xcode, the current version is 4.3.2. You can download it from the Mac App Store.
The latest stable Xcode release is 4.3.2 as of May 31st, 2012. I believe there was a version for Snow Leopard (10.6) that would not work with Lion (10.7). You'll need to be a member of the developer program (free, I believe) to get the free download here.
I have osx 10.7.X and need to install Xcode. The late xcode 5.X versions which is available in app store is not compatible with the 10.7. Xcode4.5.1 cltools is compatible.
Older versions are difficult to locate and after quite a lot of search inside developer.apple.com located the Older versions of Xcode here
Currently I am developing a Mac OS X app with XCode 3.2.5 on Mac OS X 10.6.8, the target is Release i-386. Will my app run normally on Lion?
Do I need to use XCode 4.0+?
Thanks
Every app built under the 10.6 SDK should, theoretically, work just as well under 10.7.
And you can use Xcode 3.X too, if you want. But yes, I'd recommend using the latest and greatest versions of Xcode (version 4) for development.
should you only download XCode 4.1 from the app store if you move to Lion?
i.e I am staying on Leopard for a few more weeks, so do I have to stay with XCode 4.0.2 until I move to Lion?
Yes. Xcode 4.1 Requires Lion. This has been well documented, but 4.2 is apparently available for Snow Leopard as well.
Xcode 4.2 is available for both Lion and Snow Leopard, if you download it from the iOS Developer Centre while logged in as a registered developer. The Mac App Store will only upgrade you to Xcode 4.2 if you upgrade to Lion, but you can manually install it on Snow Leopard by manually downloading it as described here, and it runs just fine on Snow Leopard.
Yes moving to Lion is a requirement. 4.1 brings all of the Lion features into the Xcode environment. I would say if you aren't ready to move to Lion yet, then just stick with 4.0.2 unless you need to develop for Lion.
UPDATE: As of Xcode 4.2, it is now for both Lion and Snow Leopard.
Yes, it seems:
This is a pre-release version of Xcode 4.1 for both Mac and iOS development. This release requires Mac OS X Lion and includes iOS SDK 4.2. Continue to use Xcode 3.2.5 on a Snow Leopard partition if you plan to submit Mac or iOS apps to the App Store

UPDATE: This question was asked in Jul 2011. As of now, Nov 2011, Xcode 4.2 is already released and made available on the Mac App store.
