Real-Time Seat Booking App for iOS

I'm looking to develop a seat booking app for iOS and Android.. The app's primary focus is on providing real-time availability of seats. The app should also integrate payment options specifically for Credit/Debit Cards.

Ideal candidates should have:
- Proven experience in iOS app development
- Familiarity with real-time data handling
- Expertise in secure payment integration
- Understanding of UI/UX best practices for booking apps
