SwiftGraph is a pure Swift (no Cocoa) implementation of a graph data structure, appropriate for use on both iOS and OS X projects. It includes support for weighted, unweighted, directed, and undirected graphs. It uses generics to abstract away both the type of the vertices, and the type of the weights. It includes copious in-source documentation, some unit tests, as well as utility functions for doing things like breadth-first search, depth-first search, and djikstra's algorithm.
A multi-tabs control first designed to look and behave like the tab control in Apple's Numbers spreadsheet, with enhanced capabilities, but now with new tab styles, such as Chrome & Safari, as well as custom ones. KPCTabsControl provides the following features: Custom styles and themes! Default (Numbers.app-like), Chrome and Safari are provided. But you can easily write your own! Styles & themes comprise title styles, title editor style, (un)selected/unselectable backgrounds, borders, colors, fonts etc. Common dataSource/delegate Cocoa APIs Tabs can span the whole view width, or be flexible inside min&max. Tabs can be reordered, and renamed in place. When provided, the title can be replaced by an alternative icon when the width is too narrow for the title to be drawn.
