I've developed a number of XCode plugins to aid me in development. The catch is that XCode don't have a public plugin API, and with it's transition towards Swift some of its parts are very hard to reverse-engineer.

• XCConsoleColorizedOutput highlighted lines in the console based on predefined conditions:

• XCodeAutocompleteFilterPlugin provided filters to autocomplete suggestions, which you can enable or disable by holding the predefined button. During that time autocomplete items were notoriously bloated in XCode, so with this plugin, by default, it hides enums, types and accessibility API, only showing those by hotkeys.

• XVim2 is a vim emulation XCode plugin, for which I've fixed a few bugs and added some features.
