I have a production-ready Android app and I now need an equivalent iOS version. The current Android build talks to a custom server for all data and user operations, so the new iOS app must hook into the same endpoints and follow the same request / response patterns. Key points • Re-create every screen and flow already present on Android, matching the existing UI/UX guidelines as closely as makes sense for iOS. • Integrate the custom-server REST calls exactly as they work today, including any authentication headers, error handling, and pagination. • Keep feature parity: anything the Android app can do—such as account management, data sync, and real-time updates—should work identically on iOS. • Deliver clean, well-commented Swift (or SwiftUI) code that I can open in the latest stable Xcode. • Provide a short README with build instructions and a list of any third-party libraries used. I’ll supply the Android source, API documentation, and sample credentials once we start. Final hand-off is the complete Xcode project plus a signed IPA ready for TestFlight.

I’d begin by mapping every Android screen to a SwiftUI flow while preserving the existing REST request/response behavior, especially authentication headers, pagination, error states, data sync, and real-time updates. Using the Android source, API documentation, and sample credentials, I’ll build the iOS equivalent with feature parity, account management, and native iOS UI adjustments where appropriate. Within 7 days, you’ll receive the complete Xcode project, commented Swift/SwiftUI code, README build instructions, third-party library details, and a signed IPA ready for TestFlight. SwiftKhata is a production POS and inventory product with an approved iOS app, giving me relevant experience across mobile workflows and data operations. Does the Android project currently build successfully against the documented server endpoints? Muhammad Saad

Hi, I can recreate your existing Android application as a native iOS app while keeping the same core functionality and integrating directly with your existing server APIs. I’ll use Swift/SwiftUI and work from the Android source, API documentation and existing flows to reproduce the screens and user journeys with an iOS-appropriate UI while maintaining feature parity. This includes authentication headers, REST API requests, error handling, pagination, account management, data synchronization and real-time updates. I’ll keep the code clean and well-structured for the latest stable Xcode, document the build setup and third-party dependencies, and provide the complete Xcode project at handover. The final stage will include testing against the existing backend, fixing device-specific issues and preparing a signed build for TestFlight. I can start by reviewing the Android source and API documentation to map the screens, flows and endpoints before development begins.

Hey, You already have the product working on Android, so the goal shouldn’t be to reinvent it for iOS, it should be to bring the same proven experience to iPhone users with reliable feature parity. I’d use the existing Android app as the functional reference and recreate the established flows in Swift and SwiftUI, including authentication, pagination, error handling, data synchronization, and real time updates using the same documented API endpoints. I’d keep the iOS project clean, scalable, and maintainable in the latest stable Xcode, while properly documenting any third party dependencies and making sure the final project is ready for future development. You’d receive the complete Xcode project along with a TestFlight ready build for testing and deployment. I can also show you similar mobile app examples in chat. Once I review the Android source and API documentation, I can identify any platform specific areas that need to be adapted for iOS while keeping the overall product experience consistent.

Hi, CnEL India can convert your production Android app into a feature-parity iOS application, using Swift/SwiftUI and the existing server APIs. Our approach: * Review the Android source, screens, workflows, API documentation and authentication flow. * Map all Android features and user journeys before implementation. * Recreate the UI for iOS while maintaining the existing product experience and adapting to iOS guidelines. * Integrate the existing REST APIs with matching request/response structures, headers, authentication, pagination and error handling. * Implement account management, data synchronization and real-time updates. * Handle loading, empty, error and network states consistently. * Structure clean, maintainable Swift/SwiftUI code with reusable components. * Test API integration, feature parity, navigation and edge cases against the Android version. * Test on relevant iOS devices/simulators and supported iOS versions. * Prepare the Xcode project, README and required third-party dependency details. * Build and validate the signed IPA for TestFlight handoff. We’ll first audit the Android app and API behavior, then develop screen-by-screen while continuously comparing both platforms for feature parity.

Respectfully, I understand you already have a production-ready Android app and need the same functionality recreated for iOS, with the existing custom server and REST APIs kept fully compatible. I can handle: Recreate all existing Android screens and user flows Match the current UI/UX while adapting it properly for iOS Integrate the existing REST APIs Handle authentication headers and API responses Implement pagination and error handling Maintain account management and data synchronization Implement real-time updates and existing app functionality Keep feature parity with the Android version Provide clean and organized iOS source code Prepare the complete Xcode project and TestFlight-ready build Provide README with build instructions and third-party libraries I can work from the Android source, API documentation and sample credentials you provide, and keep the existing backend unchanged. One question: does the Android app use any platform-specific features such as Firebase notifications, background services, Bluetooth, location or payment SDKs that also need to be replicated on iOS?

hello, Since the backend already works, the part that decides a clean conversion is reproducing the API layer exactly, since auth headers, token refresh, pagination, and error handling are where a port drifts from Android and users see subtle bugs. So I'd read the Android networking code alongside your API docs and build one shared SwiftUI service layer that mirrors those contracts precisely, testing each endpoint against the sample credentials before building screens on top. The real-time updates need the most care, since iOS suspends apps in the background far more aggressively than Android, so if they rely on a persistent socket or background sync, I'd adapt them to push notifications or foreground refresh so they behave identically for the user. Screens I'd rebuild following Apple conventions where Android patterns feel wrong on iOS, then deliver the Xcode project, README, and a signed IPA for TestFlight. How are real-time updates delivered on Android, WebSocket, FCM, or polling? And roughly how many screens are in the app? have a nice day.

Hello, I can develop a production-ready iOS version of your Android app using native Swift with UIKit, which will help reduce implementation time while maintaining reliable performance and compatibility with the latest stable Xcode. I’ll reuse the existing Android behavior and API contract to deliver feature parity without unnecessary backend changes. The implementation will include: Recreating all existing screens, navigation, and user flows. Integrating the custom REST APIs using the same endpoints, headers, request/response formats, authentication, pagination, and error handling. Implementing account management, data synchronization, and real-time updates. Creating reusable Swift networking, model, and UI components. Testing core functionality against the existing backend. Providing clean, well-commented Swift code. Preparing the README, dependency list, complete Xcode project, and TestFlight-ready signed IPA. Estimated effort: 100 -120 hours Per-hour rate: US$16/hr. This reduced estimate assumes the Android source is complete, the backend is stable and documented, design assets and test credentials are supplied, and no new features or backend modifications are required. The estimate includes development, API integration, basic device testing, bug fixing, documentation, and release preparation. I’m ready to review the Android project and API documentation immediately and begin with the highest-priority flows. Best,
