I want to learn iOS development. I have a jailbroken first gen iPod touch with iOS 3.1.3, that I was hoping to use for testing and running my app. I am running Mountain Lion with XCode 4.6 which allows me to only deploy down to as low as iOS 4.3.

I was wondering if it would be possible for me to develop iOS 3.1 apps with my XCode? or would I have to download older versions of XCode and iOS SDKs to do so?

    You will have to use older versions - Xcode 4.6 supports iOS4.3 and higher only. – Till Mar 09 '13 at 19:45

    Learning on such an older device is just going to hinder your efforts. There are so many new features in iOS and Objective-C that you won't be able to use with iOS 3.1.3. Find a used device you can buy that runs iOS 6. Or just use the simulator. – rmaddy Mar 09 '13 at 19:55

    Even though @rmaddy is certainly right, I personally feel that knowing how to do proper memory management using MRC (as opposed to ARC) has given me much better insights - those are some of the differences that he is talking about. However the time you have to invest in understanding those dated things will never be payed back in full. – Till Mar 09 '13 at 20:10

    @Till I agree that learning MRC before ARC is good. But I was actually thinking about things like all of the modern Objective-C syntax for properties, array and dictionary literals, and array indexes. And then there is GCD and multitasking. And there are so many API changes since 3.1.3. – rmaddy Mar 09 '13 at 20:13

    @Till I agree entirely, but you don't need to go all the way back 3.x to learn MRC, that is just a compiler flag. – Mike D Mar 09 '13 at 23:04
  • Yah yah yah, you convinced me... NOT :D ... cheers mates @MikeD & rmaddy – Till Mar 09 '13 at 23:07
  • @Till I strongly suspect it's possible, but you'll need to re-enable `armv6` in a plist somewhere and use `lipo` to add armv6 to `crt1.o` (`lipo`ed out of an old SDK), and for any debugging to work you'll need to grab `DeviceSupport/3.1.3` from an old SDK too (and even then I don't know if it'll work with recent Xcode). – tc.

  • @tc you wont get a deployment target below 4.3 to compile though... – Till Mar 10 '13 at 01:02
  • @Till I'm fairly sure you can if you know what files to edit. – tc. Mar 10 '13 at 01:16

No, you'll have to update to a newer version of iOS, or use bootcamp to boot to Lion with an older XCode.
