This period focused on migrating the codebase to Kotlin Multiplatform (KMP) and establishing a unified architecture for Android and iOS. Key developments included implementing local caching with Room, creating shared charting and authentication UI components, and restructuring the Android and iOS app modules. The work also involved centralizing dependency management and fixing compilation issues related to the Kotlin 2.0.0 upgrade.

The features/common area now includes the shared UI components and internal implementations for rendering bar, stacked bar, line, and pie charts. This includes the public composables (BarChartView, StackedBarChartView, LineChartView, PieChartView) that accept data sets and styles, along with internal helpers for data validation, animation specifications, and layout logic. Users can now display interactive charts with touch feedback, error states, and customizable styling across iOS and Android via the common module.

The application now includes new UI components for user authentication flows. Specifically, a 'BasicForgotPasswordScreen' has been added to handle password reset requests via email, and a 'BasicSignUpScreen' has been introduced to allow new users to register with a username, email, and password. These screens provide the frontend interfaces for account recovery and new user registration.

auth/forgot-password, auth/signup · high confidence

Introduced a new \core-network\ module providing a shared API client for retrieving cryptocurrency details, charts, and news. The implementation uses Ktor with platform-specific HTTP engines (OkHttp for Android, Darwin for iOS) and Koin for dependency injection, including error handling and JSON serialization.

core-network · high confidence

Introduced new UI screens and components for the Favorite Coins, News, and Profile features. The Favorite Coins feature now includes a main screen with user-state-specific views (authed, ghost, and premium users) and a pull-to-refresh list of favorite coins. The News feature adds a market news screen with a filter picker (Trending, Latest, Bullish, Bearish) and news cards. The Profile feature adds a drawer layout with a header displaying user info and a footer with social media links and sign-out functionality.

features/favorite-coins, features/news, features/profile · high confidence

The repository now includes a comprehensive README.md file that introduces the Dash Coin application, detailing its features, installation methods, technical stack (including Retrofit, Jetpack Compose, and Clean Architecture), and links to external resources. Additionally, an Apache License 2.0 file has been added to the project root, and the .gitignore file has been updated to exclude a specific network API file.

The core-infrastructure module now includes platform-specific implementations for background task scheduling, real-time internet state monitoring, and device motion detection. On Android, this introduces a WorkManager-based periodic worker (DashCoinWorker) that triggers background syncs at intervals determined by the user's subscription status (e.g., every 10 minutes for premium users, daily for others), alongside Android-specific connectivity and accelerometer services. On iOS, the module provides the corresponding implementations for internet connectivity and phone shaking detection. These changes enable the app to maintain data synchronization and react to device movement in a platform-appropriate manner.

core-infrastructure · high confidence

The core module now includes shared utility functions for formatting numbers, validating emails and passwords, and generating unique identifiers, alongside a constants file defining app strings and API endpoints. Platform-specific implementations for Android and iOS provide the actual logic for generating UUIDs and setting up the Koin dependency injection module, enabling the application to run on both mobile platforms.

core · high confidence

A new auto-generated BuildConfig class has been added to the shared module, exposing build-time constants such as the debug flag, library package name, and build type. This provides a centralized, compile-time accessible configuration for the shared codebase.

shared/build/generated · high confidence

The core-cache module now implements a local data layer using Room for both Android and iOS platforms. This adds a new local cache for favorite coins and user information, replacing previous remote-only or different local storage approaches. The change includes database entities (FavoriteCoinEntity, UserEntity), data access objects (FavoriteCoinsDao, UserDao), type converters, and platform-specific Koin modules to initialize the Room database on each OS.

core-cache · high confidence

The iOS application structure has been established, introducing the main entry point (iosAppApp) that initializes Firebase and Koin, and a ContentView that wraps the shared Compose UI. The project includes standard Xcode project files, configuration settings (bundle ID, app name), asset catalogs, and default unit and UI test suites.

core/build/generated, iosApp · medium confidence

The app's legacy data layer and presentation components have been removed. This includes the \DashCoinApi\ interface and associated DTOs (ChartDto, Coin, CoinDto, News, NewsDto, ReactionsCount), the \DashCoinRepository\ interface and its implementation, domain models (Charts, CoinDetail), use cases (GetChartUseCase, GetCoinUseCase, GetCoinsUseCase, GetNewsUseCase), and the \CoinsViewModel\ and \MainActivity\ that relied on them. Additionally, the Hilt dependency injection configuration in \AppModule\ and the \DashCoinApplication\ class have been deleted, along with example unit and instrumented tests.

app/src · high confidence

The core-datasource module now includes essential build configuration files: a .gitignore to exclude build artifacts and sensitive files, a consumer-rules.pro file, and a proguard-rules.pro file containing default ProGuard rules for code obfuscation and optimization.

Added .gitignore, consumer-rules.pro, and proguard-rules.pro files to the forgot-password, signin, and signup modules within the auth directory. These files configure build-time exclusions and ProGuard rules for each module.

auth · high confidence

The core-domain module now includes new Kotlin enum classes for chart time spans (1 day, 1 week, 1 month, 1 year, and all) and news types (handpicked, trending, latest, bullish, and bearish). These domain models are now available for use across the application's common code.

core-domain · high confidence

The Android application module has been reorganized from the root 'app' directory to 'androidApp', with all source files, resources, and configuration files moved accordingly. The app's visual identity has been updated: the splash screen now uses a custom 'DashCoin' icon and a blue background, the app icon has been renamed to 'ic\_dashcoin', and the status bar color has changed to dark gray. Additionally, the app now supports deep links via a new intent filter and initializes Koin for dependency injection.

androidApp · high confidence

The buildSrc module now centralizes all dependency versions and library coordinates in Kotlin files (Configuration.kt, Deps.kt, Version.kt). This update introduces support for KMP libraries, including the Konnectivity library for internet state updates, the Charts library for cross-platform graphing, and the Voyager navigation library for KMP. It also updates core AndroidX Compose, Koin, and Ktor dependencies, reflecting a shift towards a unified dependency management structure for both Android and iOS targets.

buildSrc · high confidence

The project's Gradle wrapper has been updated from version 7.3.3 to 8.8, ensuring that builds use the latest Gradle release for improved performance and compatibility.

gradle · high confidence

The \ProfileViewModel\ in the \feat-profile\ module fails to compile with a \BackendException\ from the Kotlin 2.0.0 compiler. The error occurs during IR lowering and code generation for the \updateProfilePicture\ function, specifically when handling the \updateUserProfilePicture\ flow from \FirebaseRepository\. This prevents the application from building successfully.

.kotlin · high confidence

The data and domain modules have been migrated to KMM libraries, introducing new view models for authentication flows (sign-in, sign-up, and password reset) and implementing platform-specific Google authentication providers for Android and iOS. The repository layer now utilizes a unified \DashCoinRepository\ that coordinates between local caching (DataStore, Room) and remote sources (Firebase, API), while use cases manage favorite coins and user states.

core-datasource/src, shared · high confidence

The project's build system has been refactored from Groovy scripts to Kotlin DSL (build.gradle.kts). This change introduces a centralized build configuration in the root build.gradle.kts, defining plugin versions for Android (8.5.2), Kotlin (2.0.20), and Compose (1.7.0-beta02). The migration also updates the Gradle JVM memory allocation to 4096m and configures KSP for Room database schema generation.
