SwiftGraph

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.
