NXDrawKit is an open source Swift based framework providing common components for creating drawing apps from Nicejinux.
Included within the framework are 3 different types of views, a Canvas view for drawing with redo, undo, clear, save and load, a pallet view that allows you to choose color, and alpha, and a toolbar for showing current canvas status.
