Hello!
My name is Georg.
I am new on freelancer.com but not new in iPhone development. You can examine my portfolio – a have done big projects with in-app purchase, geo location, push notifications, etc.
This project can be done in short if you accept it will be developed with Swift.
The [login to view URL] team provide good library with soket.io-client implementation.
I have already build and test example and look in the source code. As i say this should not cause problems.
So last two questions are:
the Ads. There are several providers with different level of complexity for integration.
the AppStore publication. If you want Apple native ads integration, store account required in development period for testing.
