Consume Rest Service API with SAP Cloud SDK for iOS Application (SAP iOS SDK)

I have REST service APIs of Python/Java. I want to configure the same in SAP Cloud SDK and create application for iOS platform.

I followed below link, but its configuration details are for old SAP cloud structure.

If any one can help me in configuring REST API service with new SAP cloud cockpit structure and also explain the steps to consume the same in iOS Application.

As per my analysis with REST API we don't have any metadata service, so iOS Assistance wont be able to create iOS Application for the same. So it would be helpful if any one can explain how to consume the cloud configured REST API in iOS Application for Authentication as well as fetching data.
