macOS App written in Swift to find the shortest path

Implementation of different pathfinding algorithms by using a bidirectional and weighted graph data structure WeightedGraph. You can find a generic implementation of such a graph struct in WeightedGraph.swift and its related protocols.
This was my first macOS App and it uses only cocoa bindings in the RouteSummaryViewController.
I wrote this App for the Code Competition "Der Handlungsreisende" from IT-Talents.de.
