Making it Generic
summary
Shows how generics cut a linear explosion of types in a Swift iOS app for a Glowforge 3D laser printer by replacing repeated code with one polymorphic implementation. Demonstrates concrete examples: a custom map implementation, a generic Stack<Element>, JSON parsing using Codable and a generic APIRequest that decodes network responses, and handling socket updates via resource identifier specialization. Result: fewer duplicated types, single unified code paths, and working runtime decoding from generic descriptors into concrete models.
