Swift Learning provides lessons learned from building an iOS SDK for Supportify, a help center automation service. The document outlines Supportify's goals of providing a smart help center across devices including iOS apps. It then details the process of learning iOS development through online courses and communities before using Swagger code generation to create an initial Objective-C SDK, which proved challenging. Further breakthroughs incorporating the Assistant Editor and constraints helped complete a second attempt using Swift to build a fully functional SDK.
