This blog is normally dedicated to Swift but I wanted to create a quick post for all my friends that use Xcode and didn't know about the built-in color picker and color saver.
(Not sure if it is really called a "color saver". I just made that up! :D)
This will bring up the color selector: From here you can click on the eye dropper tool, pick a color and then you can save that color by dragging the color from the big square to one of the smaller squares.
Note: The colors in the color saver/color manager persist across all projects.
(Xcode 7.3)
