Is it possible to get the iOS 5.1 SDK for Xcode 4.2 on Snow Leopard?

xcode xcode4.2 osx-snow-leopard ios5.1

Solution 1

To get Xcode 4.2 on Snow Leopard to run code on a device running iOS 5.1 you can do this:

If you have another Mac running Lion and Xcode 4.3.1 you can copy the files from:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/5.1 (9B176)
Place the copied files in the equivalent place on your Snow Leopard Mac: probably

/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Similarly copy the iOS 5.1 SDK files found in this directory:

/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk
Also copy 'version.plist' from the Lion machine in the iPhoneOS.platform folder to the Snow Leopard machine.
Re-start Xcode on the Snow Leopard machine and re-connect the devices and it seems happy enough.

If you don't have access to a machine with Lion and Xcode 4.3.1:

You can get the files out of the 4.3.1 DMG which can be downloaded from Apple here: Downloads for Apple Developers.
Mount the DMG, Show Package Contents on the Xcode icon and drill down to

/Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Follow the steps above.

You might find it more convenient to use Apple's proprietary ditto method (sudo ditto src dest) in the terminal window to copy the folders.

Note,this hack will also work for latest iOS 6 SDK.

Solution 2

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

Solution 3

I'm working on this now. I have the same issue.

The MAJOR PROBLEMS here are that:

1) Apple never provided a warning dialog that this might disable people developing under Snow Leopard.

2) There is no easy way to undo this.

3) This should not happen on a point release update.

I've tried to install the previous ipsw from 5.0.1 for my Gen 4 IPod Touch from here: where to download ipod touch firmware restore links It will not install.

I've downloaded the Lion Xcode 4.3.1 from here (sign in as a developer first) Lion Xcode 4.3.1

And run some scripts from the Dev Forums here:

sudo cp -R /Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/
sudo cp -R /Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.1.sdk /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/

sudo cp -R /Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/5.1\ \(9B176\) /Developer/Platforms/iPhoneOS.platform/DeviceSupport/
cd /Developer/Platforms/iPhoneOS.platform/DeviceSupport/

sudo rm -f ./Latest

sudo ln -s ./5.1\ \(9B176\) ./Latest

Unmounted the Lion DMG and restarted Xcode. This allowed me to test 5.1 in the simulator but broke every build to every device with a SIGABRT or link error.

I'm off to the Apple store to have them restore my device. If I get any more information, I'll let you all know. This has been a VERY EXPENSIVE and VERY UNPLEASANT surprise.

Solution 4

Adding to Richards solution above, I found that if you also copy, from XCode 4.3.1 dmg...

edit: updated to correct path within dmg

/Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Develope‌r/SDKs/iPhoneOS5.1.sdk ~~ (entire directory tree)

/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/

XCode debugger will startup correctly (without all the error log and dumps)

Solution 5

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.

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?

As Mountain lion will be released in couple of months, i dont want to upgrade to Lion now, Assuming that i should be able to upgrade to Mountain Lion from Snow Leopard. I guess i need to find a way to restore iOS 5.0.1 to my device. Thanks
Pochi about 12 years

you are welcome. It shouldnt be that hard to restore, Like i told you before, xCode provides the restore feature (found in the organizer menu window->organizer->devices->RestoreIphone). Btw dunno if you can go straight to mountain lion, as an example you have to pass trough snowleopard to get to lion from leopard.

Today i have upgraded my system to Lion. Thanks for the Hack.

Thanks very much :) Worked perfect for me. At least I'll be able to develop with sl for some more time.
Dan Dyer about 12 years

Thanks, this is almost working for me but when I try to debug an app on the device from XCode it hangs on the launch image. This may or may not be related to the fact that I downloaded the .dmg twice and both times the checksum verification failed, so I skipped it and carried on regardless.
Dan Dyer about 12 years

I fixed the above problem by also copying across the files in /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhone‌OS5.1.sdk. Thanks for this, I can now defer replacing my ancient Mac for at least a couple more months.

I think the path you mean is: /Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhone‌OS.platform/Develope‌r/SDKs (which is a bit deeper than your post suggests - complicated hierarchy Apple's ended up with isn't it?)
dklt about 12 years

indeed, you are correct. updating post to reflect your correct path. cheers ~

can someone explain this step here: then mount the DMG, Show Package Contents on the XCode icon and drill down to?

Thanks a lot. Dan Dyer's comment also helped. I'm now using iOS SDK 5.1 from Xcode 4.2

Thanks a ton! I had the same problem as Dan Dyer, but copying the file from Dan's comment fixed it.
natbro about 12 years

be sure to also follow the advice to copy the /Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/iPhone‌OS.platform/Develop‌‌e‌r/SDKs/iPhoneOS5‌.1.sdk files from the DMG into your /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/ (and the .plist mentioned in this answer), otherwise debug is fairly broken. You will also want to do a clean build of your project or breakpoints won't work
EdH about 12 years

I entirely agree with you. Apple's behavior on this is beyond irresponsible. It tells you: they just don't care.
SubG about 12 years

Richard Groves' method worked great for me - thanks. Plus with the debug issue posted by Dan Dyer, turns out that after waiting for 15 minutes (!) after app launch from Xcode, the debugger finally catches up and the app starts working... Not very practical, but keeps me working while waiting for the .dmg download...
SubG about 12 years

@natbro - I still see the 4.3.1 dmg fine at developer.apple.com/downloads/index.action# and am currently downloading it.

Thanks Substance G, the other download links listed here were failing in various ways, but that page worked fine.

I followed both Richard Groves and @dklt's set of instructions. It did not work. But I fired the scripts given in this link and it worked like a charm
natbro about 12 years

thanks @SubstanceG -- it does seem to be back, but seriously, it was not there for me then, though now it is :) still, other info still applies.
Lavamantis about 12 years

None of those DMG files at any of the links above would open for me on Snow Leopard - they all said invalid checksum. Luckily, I had an old USB harddrive and installed Lion on it. It doesn't recognize my Bootcamp partition (bad!), but at least I was able to grab the SDK and finish up my app. Thanks.

Apparently it will not be necessary to upgrade to Lion first and you can go straight from Snow Leopard to Mountain Lion

@Richard Groves: is there any way to upgrade IOS 6 simulator for in xcode 4.2 snow leopard as like device SDK?

This seems to work initially, but I get the following error when I attempt to switch between viewControllers when I test with my device: Error Starting Executable “AppName" Error launching remote program: failed to get the task for process 453. @Richard do you know why?
JRoss over 11 years

I also installed the iOS 6.0.1 files from XCode 4.5.2.dmg @HenrikErlandsson, but I get the above error when I attempt to test on my device (iOS 6.0.1). Do you experience any problems?

I get the following errors when I do this @hchouhan02: Interface Builder XIB Compiler Error: "Command /Developer/usr/bin/ibtool failed with exit code 255" and Uncategorized: "Build task failed without generating error messages."
Henrik Erlandsson over 11 years

We tested this before the holidays. I can build fine for an Iphone 4S with latest 6.0.1 (10A523), but not with an Iphone 5 with latest 6.0.1 (10A525). We think the reason XCode can't green-light the device in Organizer has to do with the change in upgrading method (over-the-air, no files to download on developer.apple.com), but if someone succeeds we'd like to hear about it.
