How to theme the ENTIRE Xcode IDE to light-on-dark?

Question

On OSX, MacVim and Terminal can both be themed to be light-on-dark. Xcode 3.2 allow the same customization for its editor using color schemes.

However, is there a way to do the same to its UI panels ("Groups and Files" left pane and the list view top pane for example)? If not, is there a quick way to toggle both panels on/off?

Answer 1

While you can't adjust the IDE color scheme, you can quickly toggle the navigator, debug area, and utility views with the following commands:

Navigator : ⌘0

Debug Area : ⇧⌘Y

Utility : ⌥⌘0

So, if you set your theme to one with a dark background, you can quickly close/open the lighter portions of the IDE as needed.

You can also change the debug console to have a different background by going into preferences ⌘., then go to Fonts & Colors, then select the Console. Now you can edit its background:

Just be sure to edit the font colors of the various input and outputs texts if you choose black. By default all of the input/output fonts are black, only the console prompt is not.

Answer 2

One possibility for now: System Preferences => Accessibility => Display => Invert Colors.

Note that Apple recently announced at WWDC that Xcode 10 will support "dark mode" as of some time in late 2018.
