Project description:
"I need to bring my cab-hailing app up to date on both iOS and Android. Every third-party library, native framework, and in-house feature has to be migrated to the latest stable versions so the builds compile cleanly in Xcode 15 / iOS 17 and Android Studio Giraffe / Android 14, without breaking any existing functionality.

Your work will start with a dependency audit: identify outdated Swift, Kotlin/Java, and cross-platform libraries, note deprecations, and map out the required migration steps. After the libraries and core frameworks are upgraded, you’ll modernise the app-side features that rely on them—push notifications (APNs + FCM), real-time driver tracking with maps, in-app payments, and the background location service.

Because the app is live, stability is critical. Unit tests and basic UI tests already exist; they need to pass on the updated codebase. Any new breaking changes introduced by Apple or Google must be handled with graceful fall-backs so riders and drivers on older OS versions can still use the service.

Deliverables
• Updated iOS and Android source code compiling without warnings on latest IDEs
• A change-log summarising all library, framework and feature updates
• Test report showing 100 % pass rate of existing tests plus any new tests you add for migrated code
• Two signed release builds (IPA & AAB) ready for App Store / Play Console submission

I am happy to answer architecture questions and will provide full repo access once we agree on milestones." (client-provided description)
