There is no defined keyboard shortcut to show/hide the document outline. But you can define new shortcuts for these actions.
Just open the preferences (cmd+,) and search for "Document Outline" in the "Key Bindings" page.
سؤال
I need to frequently hide and unhide navigators and inspectors to make room for Interface Builder and complex storyboards. I learned all show/hide shortcuts in Xcode for panes, but can't find any for showing and hiding Document Outline. Is there a way to achieve this on keyboard?

Just to demonstrate the other solution how to setup the shortcut in System Preferences->Keyboard->Shortcuts.
In one of the Xcode updates 6 or 7. ⌘9 is re-allotted for Navigators > Show Reports Navigator
so, System Preferences > Keyboard > Shortcuts > App Shortcuts > Show/ Hide Document Outline ⌘9 is invalidated by Xcode automatically.
⇧⌘9 is what I chose. in the Keybindings.
