IOS Developer - professional and experienced to build a simple app

General information for the app: the app displays listings for restaurants and bars
Kind of development: New app from scratch
Num. of web pages/modules: 8 templates
Description of every page/module: The back-end service (API) is already written and we have documented each operation with example code for requests and expected responses from the API. There are eight possible endpoints within the API.
Description of requirements/features: We have already completed a version of the APP in Android which has tested all of the API requirements and endpoints so we now just need the exact same treatment in IOS. This is only for iPhone not for iPad.
