This tip is for iOS developers who want to reduce the time taken while searching iOS documentation using Xcode. Documentation under the Xcode organiser window by default shows information on OS X as well. If you are not a Mac developer then you can turn off the documentation related with OS X.
Step 1: Launch Organizer window in Xcode and navigate to Documentation tab.
Step 2: In the Documentation window, navigate to the Search Documentation option and click the arrow pointing downwards under the search icon.
Step 3: Now select Show Find Options from the menu list.
Step 4: Navigate to the Find in list box then deselect “OS X 10.7 Core Library” and “OS X 10.8 doc set”.
This would exclude the OS X library while using the documentation search on Xcode.
