I am trying to install the iOS 5.1 Library Documentation. But the scariest thing is that after the entire download is complete (not at the start of the download) it gives me the following error message.
How to solve this problem.
I don't know if this is the best solution, but ....
follow these two steps:
$ cd /Users/youruser/Library/Developer/Shared/Documentation/DocSets $ sudo chmod -R 777 .
I think it will work.
