Select Fold from menu list. It will fold your code and shows 3 dots, folding/covering entire block. Now, to again unfold your code block, release ⌘ (command) button and click on 3 dots folding a block.
As of Xcode 4 it seems to have changed.
command-alt-shift-left arrow will do the trick...
To fold/unfold current methods or if
structures use:
Fold: command-alt-left arrow
Unfold: command-alt-right arrow
Updates in Xcode 10
