-The repository contains examples of common `Algorithms` and `Data Structures` implemented using the latest stable version of `Swift`programming language. The development attempts to fully utilize `Standard Library` and `Protocol-Oriented` paradigm. The project provides interactive visualizations using `SpriteKit` and `SceneKit` frameworks (in development).
