Unit Conversion

This project is a demonstration of how to securely encode/decode custom objects that have properties of types that do not conform to Codable protocol.

Project overview

A Simple unit conversion app using Apple's Units and Measurement APIs, to convert between measurement units -Dimension, using .converted(to:) to produce the required result. We have array of units (Area, Length, Mass, etc..), map of unit types -Dimension in each unit -[String, [Dimension]],  and we have list of favorite conversions, these favorites will be persisted in Document Directory folder, for easy access.
