Is it possible to get the iOS 5.1 SDK for Xcode 4.

Question

I still have Snow Leopard. I have Xcode 4.2 for iOS development. This morning I upgraded my iPhone and iPad to iOS 5.1.

But Xcode 4.2 is not detecting my device for testing. I could not find the iOS 5.1 SDK image on Apple's developer site, for Xcode 4.2.

I don't want to do upgrade to Lion to get XCode 4.3 at this time.

Will I able to use Xcode 4.2 (on Snow Leopard) for iOS development now?

Answer 1

I am using Mac OS X 10.6.8 and Xcode 4.2 and also upgraded my iPhone to iOS 5.1. I needed to get a test version onto the device in a hurry yesterday but did't have the time to install Lion and Xcode 4.3.

I've been using TestFlight (www.testflightapp.com) for beta testing. I created an .ipa archive from Xcode 4.2 and was able to install it on my iOS 5.1 upgraded iPhone via TestFlight.

I know it's not an ideal solution but it helped me get out of a tight spot yesterday without resorting to hacks.

p.s. I'm not affiliated with TestFlight in any way.

Answer 2

As of the date of this writing 3/20,2012, Apple is not letting people install previous ipsw files from 5.0.1. If you upgraded your device to iOS 5.1, like I did with my gen 4 Touch, then you either have to get iOS 5.1 running in Xcode 4.2, or you have to revert your device to 4.x, or you replace your device.

I brought my touch to the Apple Store and they replaced it.

If you install the ipsw for 5.0.1, Apple's servers will state that this is not allowed for your device and you will be unable to revert. You'll have to try 4.x to your device or make sure that the iOS 5.1 SDK is running in Xcode 4.2.

Answer 3

You have to get Lion, iOS 5.1 SDK is only for Xcode 4.3.1 which is only available for Lion.

... and your Xcode will not be able to build to your device if you have already updated it to 5.1 because it won't be on that version of Xcode's approved SDKs

Answer 4

There is an answer here that also provides the copy of the simulator v 5.1. No manual operations. Just open the Terminal, copy and paste the provided commands.

Answer 5

I think you can test ios 5.1 device in Snow Leopard as explained in above posts. But it is always safe to upgrade to Lion and use the official sdk release. Because we cant predict what issue could happen if we do some "Tricks" on our machine to make it happen and it may happen when in your most unwanted time (like when submitting to appstore). :)

Answer 6

Download the iOS 5.0.1 firmware of your device on this link : http://www.iphonefirmware.com/firmwares-download.

And do a manual restore on iTunes.

I did it today (March 8) on my iPad 2 and it works, Apple still seems to sign this iOS version.I guess not for a long time, so do it quickly.
