iOS Native App Development - Video Content and User Generated Content App

I need a Native iOS app developer to build an app for video content and user-generated content. The app will have features that provide access to videos, audio, images, text, chat and calls. This app will also need to be integrated with certain existing APIs. I'm looking for an experienced developer with a history of building quality applications who is comfortable working on this kind of project. The app also needs to be compliant with Apple standards and have clear navigation. Any suggested improvements or changes to the app are also greatly appreciated.
