Yangys worked on the HIUMC/UMC-8th-iOS-Study repository, building the foundational architecture and core features for a Starbucks-themed iOS application. Over three months, Yangys established scalable project scaffolding, implemented login and signup flows, and developed location-based store discovery using Swift, SwiftUI, and MVVM. The work included integrating assets, designing reusable UI components, and modeling data for coffee and store information, while maintaining repository hygiene and refactoring for long-term maintainability. Yangys also introduced backend integration readiness with Spring Boot and Gradle, creating an API testing playground that improved testability and enabled faster, safer feature delivery across both mobile and backend services.

May 1, 2025Monthly summary for 2025-05: - Focus: Deliver end-to-end feature capabilities for HIUMC/UMC-8th-iOS-Study and strengthen backend integration readiness. The month delivered three major work streams: core Starbucks app features, location-based store discovery UI, and a foundational backend/API testing playground. Key features delivered: - Starbucks App Core Features and UI Scaffolding: Introduced a substantial set of Swift files and assets for the Starbucks app, including models for coffee and bread assets, login and signup flows, and store information, paired with view models and UI components to enable core functionality and a cohesive UI. Commits: c49ce100375e6c01120d5afe3f441f57b794a7a1. - Location-based Store Mapping and UI Enhancements: Restructured data models (MapListModel, Marker) and updated MapView and OrderSheetView; added MapTopSegmentView and refactored related views to improve the location-based service UI. Commits: 9fb611f12dd12a91ba1004ca282f6293c0683180; 13a93592c2aee0fc29c9a547b6ff3970460a3505. - Internal Refactor and Backend/API Testing Playground: Cleaned up project structure and main application view; introduced an API testing playground and backend scaffolding (Swift Playgrounds, Spring Boot web app, Gradle config, dependencies) to support development work. Commits: 4d0b437bd834d6d3b88fbf70b2184b3d05aab9fe; 3120be1027629d0f5ed3113e3eb306f2f559cdfd. Major bugs fixed: - No discrete bug fixes were tracked this month. Focus was on feature delivery and architectural improvements to reduce defect risk and improve maintainability and testability for upcoming QA cycles. Overall impact and accomplishments: - Accelerated feature delivery for the Starbucks app with a solid core feature base and improved onboarding of new UI components. - Enhanced user experience and reliability of location-based store discovery through data-model and UI refactor. - Established a scalable testing and backend integration pathway, enabling faster iteration and safer deployments across mobile and backend services. Technologies/skills demonstrated: - Swift, SwiftUI, and MVVM architecture; Map-based UI and data modeling. - Architectural refactoring for maintainability and testability. - API testing tooling with Swift Playgrounds, plus backend scaffolding using Spring Boot and Gradle; dependency management and project structuring for cross-team collaboration.
