I’m running on XCode 4.2 with iOS 5 on Snow Leopard using iMac Early

  • 0

I’m running on XCode 4.2 with iOS 5 on Snow Leopard using iMac Early 2006 (Intel Core Duo 32bit). I’m waiting for iMac Late 2012 27 inch to arrive while I wanted to be ready with my app. At the same time, I wanted to move to iOS 6.xx SDK with XCode 4.5 on Snow Leopard. I have been reading some of the posts on this combination on Snow Leopard. My questions are:

  1. Is the fix to use XCode 4.5 with iOS 6.xx on Snow Leopard really working for people?

  2. I read that you can’t use the iOS 6 simulator on a 32 bit iMac. Is this true?. If it is, is my only option to test the app on the device?

  3. Can XCode 4.2 and XCode 4.5 co-exist or is it going to be a upgrade from 4.2 to 4.5?

Please advise.

    Regarding two versions of Xcode co-existing, here is a thread that addresses that (with the note that it’s an older thread so there may be some differences for App Store Xcode vs. downloaded Xcode): Can I have multiple xcode versions installed?

    In my own experience/research while I was on Snow Leopard, I did not find any positive results regarding running Xcode 4.5 or iOS6. I stuck with 4.2 and temporarily ran 4.5 on a separate Lion machine until I was able to upgrade. I also had no success using my iOS6 device for testing while connected to Xcode 4.2 (a message to the effect of “no device with compatible OS”), so I had to connect the device to the separate Lion machine as well.

    If your new iMac is already on the way, I think you’ll save a lot of headaches just holding out for that rather than trying to jury-rig the Snow Leopard machine. Once I updated to Mountain Lion, the transition from 4.2 to 4.5 for my project was very quick and easy.
