xcode 4.5 OSX 10.8 CoreLibrary(529mb) install error like this.
"Failed to install documentation for OS X 10.8 Core Library" Installation path is /User/*/Library/Developer/Shared/Documentation/DocSets/com.apple.adc.documentation.AppleOSX10_8.Core...,points to a folder that does not look like a valid documentation set for updating
And simulator 6.0 lunching time is very slow(rather than simulator 5.0).
My mac os is "Mountain Lion".
I already try reinstalling but not working.(use AppCleaner)
I found a previous unfinished download left files to be deleted.
