Over three months, Chang Lang built the foundational architecture for a Starbucks-themed iOS app in the HIUMC/UMC-8th-iOS-Study repository, focusing on scalable project scaffolding, authentication flows, and location-based store discovery. He established a modular SwiftUI codebase, integrating an API service layer with Moya and Alamofire, and structured data models for authentication, orders, and stores. By incorporating GeoJSON for store locations and implementing Kakao social login, he enabled realistic testing and streamlined onboarding. His work emphasized clean project setup, asset management, and UI/UX design, resulting in a maintainable codebase that supports rapid feature development and efficient team collaboration.

Jun 1, 2025June 2025 — Delivered initial project scaffolding for the Starbucks-themed iOS app (HIUMC/UMC-8th-iOS-Study). Established core architecture with an API service layer (Moya/Alamofire), data models for authentication, orders, and stores, and a UI skeleton (ContentView). Seed data integrated via GeoJSON to enable realistic development and testing of location-based features. This foundation enables rapid feature delivery (auth, orders, stores) and improves testability and onboarding for new contributors. Two commits completed to seal the scaffolding: week7 (db4667802d3c0b4ec6e785c9a0d6093d47caaff5) and week8 (14fa462821dccf1f466eb2d2c5d753b31d998ed4). Major bugs fixed: none documented this month; focus was on scaffolding.
