A workaround - open your browser and go to:
file:///Users/userName/Library/Developer/Shared/Documentation/DocSets/com.apple.adc.documentation.AppleiOS7.0.iOSLibrary.docset/Contents/Resources/Documents/navigation/index.html
(replace userName)
Exactly so. I've bookmarked that in my browser. But it would be nice to make that page appear in the doc window. You can *sort* of do it with this link:
xcdoc://ios/navigation/index.html
Copy that and paste it into the search field in the doc window. The page does try to appear but mostly it sort of wedges Xcode; it just doesn't have the browser cojones for this page, I think.
