During a two-month period, Litt22 focused on stabilizing the HIUMC/UMC-8th-iOS-Study repository by addressing issues introduced through prior structural and feature changes. Working primarily with Swift and SwiftUI, Litt22 reverted problematic commits that had caused instability in the iOS project, restoring the codebase to a previously reliable state. This included rolling back experimental map, search, and Kakao API integrations, as well as OSRM routing components, to ensure consistent build reliability and reduce maintenance risk. The work emphasized risk mitigation and codebase cleanliness, supporting ongoing development and onboarding by maintaining a stable foundation without introducing new features during this period.
