Apple Event: May 7th at 7 am PT
I have installed Xcode 4.1 in Mac OS lion 10.7, Xcode is failed to download the Mac OS X 10.7 Core Library, but Xcode4.1 download Xcode4.1 developer library successfully. who knows why it is?
I had the same problem (iOS dev account only), but I restarted XCode 4.1 this morning and it's now re-downloading all the doc sets, including the 10.7 docs. Maybe something was fixed/changed on the server side?
Yes, Apple fixed at server side.
July 22 @ 10:20 PM. Still having the same issue, no 10.7 core libraries. This is not even the library itself, it's the documentation. It really does not make sense that Apple would be restricting it to OS X developers only, when the code is still accessible to all Xcode users. Hope this gets fixed soon, it is a pain because Xcode keeps trying to download it in the background. I caused my pc to freeze several times due to it.
I only have an iOS dev account, and I'm getting the OS X 1.7 doc, so the problem isn't that Apple is restricting the docs. Sounds like a server issue (that's fixed in my case now).
I just tried right now, Apple has fixed it, we can download the library now, please try it again. and I am a iOS developer.
Same as cageface and ExBruce, my problem has been fixed and all the libraries downloaded correctly.
Thanks for your help!
A server with the specified hostname could not be found.
http://developer.apple.com/rss/com.apple.adc.documentation.AppleLion.atom contains three links:
http://pubsbuild.apple.com/com.apple.adc.documentation.AppleLion.CoreReference.xar.
The most recent was added at wedneday. I think pubsbuild.apple.com is some internal web server. And it just the matter of a broken link.
For anyone else having this problem will trying to download the newest docs,
Is the correct download link. The rssfeed contains both the good link and the bad link however the bad link is listed first and is the one xcode tries to download from. It looks like they added the good link at the bottom of the list after the olderst version, where it is ignored by xcode.
Having the same problem, and it does appear to be related to the bad hostname, pubsbuild.apple.com, that is triggering the failure.
Additionally, the feed XML itself is malformed. There's a double closing </feed> tag at the end, although I suspect that's not relevant to this issue.
That much being said though, the root URL from which all this data is loaded appears to be legit. The problem seems to be bum content in the feed. Unless you really need this documentation now, I'd suggest you give Apple some time to fix the feed rather than point your download to a URL that will become obsolete once the next documentation update comes out.
Just my two cents...
Same problem here as well😟
