November 2024 at wikimedia/wikipedia-ios delivered impactful Year-in-Review (YiR) enhancements, workflow improvements in Settings, and expanded localization, underpinned by solid data engineering and accessibility work. Key YiR enhancements included a redesigned UI/UX with a feature announcement frame, shareable view, profile and notification badges, updated intro copy, and a badge refresh flow after viewing YiR, plus a survey trigger after two slides and navigation guards to prevent overshooting slides. Region-based donation button visibility was introduced to tailor fundraising UI by country. In-app WebView improvements streamlined information access and focus. Internationalization and localization broadened reach with IT and ES additions, localization string updates, and a bug fix for Italian localization. Data-quality and architecture improvements were realized through Saved Articles data handling (Core Data persistence, per-period retrieval, and personalized saved count UI) and a Data Controller refactor moving count logic from the view model to the data controller. Accessibility and UI polish were enhanced (labels, tap targets), and stability gains came from test fixes and a release bump to version 7.6.3.
