Hello, What is your problem? And what is your box?
I am an iPhone developer using SWIFT.
I know well about developing apps such as the Taxi company app, Taxi Booking App, Delivery App, Betting App, and Social Media App…
And I can integrate the services to the app, for example, BT feature, Google Firebase Service, Google Maps, GPS, etc..
I hope to work with you.
Best Regards...
Thank you for your reading
