Xcode unofficial (and undocumented) theme support

Most people is familiar with Xcode theme support for the text editor. You simply open Preferences, Fonts & Colors and duplicate an existing theme (or create a new one from scratch). Xcode editor themes have the .dvtcolortheme extension.

However, there's some support for themeing Xcode itself (fonts, gradients, colors). Xcode loads the default theme from /Applications/Xcode.app/Contents/SharedFrameworks/DVTKit.framework/Versions/A/Resources/Default.dvttheme.

.dvttheme files are simply XML files that conform to an undocumented schema. If you want to modify any of the settings in Default.dvttheme, instead of modifying the bundle resource file you can instruct Xcode to load your custom .dvttheme from wherever you want:

This file generates a flowchart in PNG format from two Markdown tables: The first one specifies the different states and the second one specifies the transitions between states.

Requires Graphviz (https://www.graphviz.org)
