My computer system is Windows so I cannot run your application properly. So my suggestions are purely based on reading the files in your github repository.

• The instructions on your README file could be more detailed from how to install the application to how to use the functions properly.
• There could be more explanation on how each algorithm works together as a whole. Since your code were mainly written in swift, I personally find it difficult to understand each algorithm even though many of your swift functions are well-commented.
• Your directory structure and file organization could be more concise, like if there suppose to be a new version of your application under Versions/current directory. Also it would be nice if you include some reference sites in your description file.
• Your project looks fancy and interesting and I am looking forward for an user-friendly app.
