XCode 4.6 keeps on downloading Doc Set

Question

Since I installed XCode 4.6, it keeps on downloading the Doc Set each and every time I open it. I've seen a lot of threads talking about this topic, so I tried to manually install the doc set in the Developper/Shared/Documenation/Docsets folder. But even with that, I opened XCode this morning and.... it started downloading the thing again. What can I do to make it stop ?

Answer 1

Click the link under Xcode->Preferences Click on Xcode 4.6 doc set you will see an installed location. click on that link and delete the file. In my case there was another Xcode 4.6 file I think it was called Xcode 4.6 Documentation set I deleted that as well.

I closed XCode and opened up again the told it to download it again and it took.

You should only have one Xcode 4.6 file in your list I had two and I don't know why. Might be something left over from the 4.6 beta.

Hope it help

Answer 2

Go to the "Xcode->Preferences->Downoloads" and unselect the check mark under "Check for and install updates automatically" in the "Documlentation" tab.

Answer 3

Downloading Fresh Doc

As the other answers suggest, Xcode is merely detecting, downloading, and installing new versions of the documentation available on the Apple servers.

Disable Auto-Download

As pablok said, if you don't like this behavior, disable the behavior by unchecking Xcode > Preferences > Downloads > Documentation > Check for and install updates automatically.

Fresh Doc Stored Outside App

One interesting twist is that the old versions are stored inside Xcode.app while the fresh downloaded versions are stored outside the app.

For example, in Xcode 4.6.3 on Mountain Lion obtained from the developer.apple.com iOS Dev Center, the Xcode 4.6 doc set is bundled with the Xcode app. That bundled doc set, according to the Finder, is:

• Version: 509.12
• Size: 268.4 MB
• Location: …/Xcode.app/Contents/Developer/Documentation/DocSets

The newly downloaded doc set is:

• Version: 511.5
• Size: 286.8 MB
• Location: ~/Library/Developer/Shared/Documentation/DocSets

So, two mysteries:

• Why does Apple bundle doc inside the app but download new doc somewhere else?
• After doing so, why does Apple leave the old doc in place? Why not delete it?

As an experiment, someday I will delete the original ones inside the app. I'm not suggesting any benefit (other than recovering storage space) nor am I saying there is no adverse effect.
