IOS App - Travel Industry

General information for the business: We are building an online ordering app
Kind of development: Customization of existing program
Description of requirements/functionality: Users have access to multiple restaurants but can order only from one at a time. We have part of the app built, but need help building piece with Menu Listing and Ordering workflow. We have a small tech team building the app and the backend. Our APIs and specs are built out and well documented with clear screen workflows built.

What needs to be built:
• Restaurant Menus:
o Showcasing a menu (connected to an API)
• Cart:
o Standard cart operations, e.g. Add, update, remove items to/from cart (with modifiers, see below)
o Items can have add-on options and products, e.g. ordering Pizza can have 3 topping options
• Order processing:
o Order review and order submission
o Tracking and Status view
• Payment Processing:
o We are using Braintree

What will be made available to you:
• Our APIs
o Retailer Information (e.g. menus)
o Cart operations
o Ordering and Status tracking
• Sketch Mockups for all needed screens
• Well-documented (and access to author) APIs
• Braintree iOS Sample codebase
Specific technologies required: Swift, iOS
