ExperiencesiOS App: Queen's game
We published an native iOS game application to the App store. This app provides a multi-payer game to play between your friends and neighbors. Since this game includes great random factors and customization, each time a player will be provided with variable joys. This app has a lot of UI factors and data models with a reactive relationship. Thus, we adopted RxSwift and MVVM design patterns to completely separate views, models, and logic.
iOS App: Hang out Planner
We created a native iOS application with Swift. This app suggests optimized root which includes locations that the user prefers. This app uses modern collection views with diffable data source, async API-fetch with dispatch group.
