Over three months, Bastian Bittorf enhanced deltachat/deltachat-ios by delivering 49 features and resolving 19 bugs, focusing on proxy management, widget integration, and UI reliability. He implemented robust proxy workflows, including safe deletion, QR code generation, and onboarding integration, using Swift and UIKit. Bastian refactored the widget system for multiple types, improved localization, and upgraded the codebase to Swift 5.5, ensuring compatibility and maintainability. His work included responsive layouts, CI/CD improvements, and dynamic content loading via WebView. The depth of his contributions is reflected in improved user experience, reduced technical debt, and a more stable, maintainable iOS codebase.

Jan 1, 2025January 2025 (2025-01) – deltachat-ios Key features delivered: - UI image handling: fixed image tinting to preserve original colors and added a placeholder initials/color when no image is set, improving visual fidelity in profile views. - App navigation and listing UX: implemented a refined app-picking flow, removed the legacy app-selector, and reintroduced navigation with a close button; enhanced app listing with smoother loading, visibility of most recent webxdc-apps, and a segmented control with localization support. - Web store integration: added a basic webview to display the store, enabling in-app store exploration. - Widget reliability and state management: ensured widget state is cleaned up when chats or messages are removed, preventing stale widget data. - Widget update policy: changed to update only on changes rather than auto-updating, reducing unnecessary widget churn and improving power efficiency. - App-picker enhancements and layout: enabled swipe-to-dismiss, ensured apps-tab remains visible, and added responsive layout for orientation changes (landscape constraints handling). - Localization and CI improvements: updated translations across the app and hardened CI workflows to improve consistency and reliability. Major bugs fixed: - Image tinting regression resolved; placeholder behavior and color accuracy restored. - Widget cleanup on removal fixed to avoid orphaned data. - Legacy UI cleanup and build stability improvements across multiple commits, reducing warnings and build failures. - UI input handling fixes: keyboard dismissal behavior and proper cancel button usage clarified. - Orientation and layout fixes: landscape constraint corrections and responsive grid adjustments. - API removals and housekeeping: removed obsolete DcContext.hasWebxdc usage to align with updated internal APIs. Overall impact and accomplishments: - Substantial improvement in visual fidelity, stability, and user experience with fewer UI regressions and clearer app navigation. - Reduced widget noise and improved performance through targeted policy changes and cleanup. - Enhanced developer velocity via CI improvements, code cleanup, and localization updates. Technologies/skills demonstrated: - iOS UI development (Swift/UIKit/Auto Layout), widget extensions, and SwiftUI concepts where applicable. - WebView integration and dynamic content loading. - Localization workflows, translations management, and internationalization. - CI/CD optimization, build stability, and automated quality checks. - Refactoring, legacy UI cleanup, and orientation-aware responsive design.
