Develop iOS in swift

I'm seeking a skilled developer to build an iOS app with the same features as our existing Android food delivery app, focusing on catering and bulk order delivery. The app should achieve feature parity with the Android version, excluding user reviews and ratings, to meet the project deadline. The developer will need to refer to the Yumzy app on the Playstore to understand the flow, as no Figma file will be provided. The Product Manager will supply user stories as needed.

Key Requirements:
- Develop the app for iOS 14+ using Swift (native), with the option to use Flutter or React Native if preferred.
- Omit user reviews and ratings from the iOS version.
- Support catering options for corporate events, private parties, and weddings.
- Integrate payment methods including Credit/Debit card and Paytm SDK.
- Deliverables include the iOS code and a TestFlight build for testing.

Ideal Skills and Experience:
- Proficiency in iOS development using Swift, with experience in Flutter or React Native as a plus.
- Experience in converting Android apps (Kotlin) to iOS.
- Familiarity with integrating various payment gateways.
- Ability to work with minimal design documentation and develop based on user stories.

The Kotlin source code of the Android app can be provided for reference. Post-development, a maintenance charge can be discussed based on hourly rates or project scope.
