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 Your work will start with a dependency audit: identify outdated Swift, Kotlin/Java, and cross-platform libraries, note deprecations, and map out the required migration steps.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.

Hi there, I am confident in my ability to bring your cab-hailing app up to date across both iOS and Android platforms. With extensive experience in mobile app development, including a strong background in upgrading dependencies and frameworks, I will conduct a thorough dependency audit to identify and address outdated libraries, ensuring a smooth upgrade to the latest stable versions of Swift, Kotlin, and cross-platform libraries. I understand the critical importance of maintaining the stability of a live app, and I will ensure that all existing functionality remains intact while implementing graceful fallbacks for any breaking changes introduced by Apple or Google. I will provide updated source code that compiles without warnings, alongside a detailed change log and test reports demonstrating full pass rates. Let’s discuss your specific requirements in more detail and agree on milestones. What specific features or functionalities do you want to prioritize during the updates?

Greetings, I understand you need your cab-hailing apps fully migrated to compile cleanly on Xcode 15 / iOS 17 and Android Studio Giraffe / Android 14, with a dependency audit, safe library upgrades, feature modernisation (push, maps, payments, background location), tests passing, and signed release builds. A few quick questions to scope precisely, 1. Is there an existing CI pipeline that currently runs the unit and UI tests, and do they pass on the current branches? 2. What minimum iOS and Android OS versions must we continue to support for graceful fall-backs? 3. Any third-party SDKs with enforced contracts or vendor support windows we should prioritise (payments, maps, analytics)? Our team includes senior iOS and Android engineers, QA engineers, and DevOps, experienced in large migration projects, dependency audits, and Play/App Store releases, we deliver clean commits, a migration changelog, and release-ready IPA and AAB files. Please chat so I can review repo access, propose a short milestone plan, and provide an exact quote quickly, current bid is a placeholder to submit the proposal. Regards, Yasir LEADconcept PS, I can share migration case studies and before/after test reports on request.

Hello, I have read your requirement to bring your cab-hailing app fully up to date for both iOS and Android. I can do that, and I have over 8 years of experience in mobile app designing and development with backend integration. I’ve worked on several live apps that required major version migrations, ensuring zero downtime and clean builds on the latest IDEs — Xcode 15 / iOS 17 and Android Studio Giraffe / Android 14. My approach will start with a complete dependency and framework audit across Swift, Kotlin/Java, and any cross-platform modules. I’ll identify deprecated APIs, plan the migration path, and then upgrade each library systematically without breaking existing functionality. Once the app compiles cleanly, I’ll modernize your push notifications (APNs + FCM), maps and real-time tracking, in-app payments, and background location features to align with the latest OS standards. Since the app is already live, I’ll maintain stability as the top priority. Your existing unit and UI tests will be preserved and updated as needed to ensure 100% pass rates. You’ll receive fully updated source code, a detailed changelog of all upgrades, and signed IPA & AAB builds ready for submission to the App Store and Play Console.

Hi — Elias from Miami. I’ve read your brief and I can take this to production: full dependency audit → library & native framework migrations → feature modernisations (APNs + FCM, real-time tracking, in-app payments, background location) → test validation → signed IPA & AAB. I’ll keep all existing behaviour intact, add graceful fallbacks for older OS builds, and deliver a clear change-log + test report showing passing unit/UI tests (plus any small tests added for migrated paths). I’ll need repo access and provisioning/keystore to produce the signed builds. Planned approach (high level) • Audit: list Swift/Kotlin/JS libs, deprecations, potential breakages. • Migration plan: per-library migration steps and risk level. Q1: Which map + realtime SDKs and payment provider are currently used (Google Maps / Mapbox / Mapkit, Socket/Realtime lib, Stripe/Adyen/Braintree)? Q2: Do you have CI/CD (Fastlane, GitHub Actions, Bitrise) and existing app store / play console credentials & provisioning/team access? Q3: Any custom native modules (private CocoaPods/AARs or internal SDKs) or server changes required for token/auth flows? Q4: Can you confirm the minimum supported iOS/Android OS versions and whether you require maintaining official support for those older OS builds (so I can scope fallbacks)? If that lines up I’ll prepare a scoped proposal and milestone breakdown once I can peek at the repo. Looking forward — Elias

Hello, I can help you bring your cab-hailing app fully up to date so it compiles cleanly on the latest versions of iOS and Android. I’ll start with a careful review of your codebase to list outdated libraries, frameworks, and APIs, then upgrade everything step by step while keeping existing features stable. I think handling the migration in small chunks and testing after each phase will make the process smoother and reduce the risk of breaking live features like maps, push notifications, payments, and background tracking. Once everything builds without warnings, I’ll run your existing tests and add new ones if needed to confirm nothing was affected. You’ll get clean iOS and Android builds, a full changelog, and a report showing every test passed before we prepare the release versions for submission. Let me know if you’d like me to start with an audit of the current dependencies. Best regards, Kamran
