Reskin our iOS app, add new api and upload to App Store

Pickup project from current developer who will provide guidance via skype

We have already developed an IOS app and we have new design (Sketch). Total screens to be reskinned will be 8-9 screens. Also, there is a new API that will be needed to be added to save documents in the app (we already caching documents in the app when open them) but this new API got new structure for the documents.

Code is clean and all functionalities in the current app are working properly.

Old dev will supply the new developer with the complete source code of the project. New dev will makes the new design and changing from dev to live servers (is just changing the base url )( Old dev will be online here anytime new dev wants something just message.) Once changed from dev to live, then upload to the app store and supply files and source code.
