Functional Requirements

• Display a list of products showing at least the title, price and an image for each one
• Customers should be able to search for products by their name
• Selecting a product from the product’s list should display a details page, where customers can find out more information about the product
• Products should be persisted​, meaning that if the app is relaunched when the device has no internet connection, the last downloaded list of products are displayed

Non Functional Requirements

• The app should be built with good UX and use iOS native UI elements where possible, with a design of your choosing
• Critical aspects of the app should be covered by Unit Tests
• A core user journey should be covered with a UI Automation Test
• Document in the README anything that is worth noting
• If used, justify the use of any third party libraries in the README

Dependencies used

AlamofireImage - I used this because its a solid image fetching implementation that handles caching and is well supported by the community for new iOS versions. I believe where possible we shouldn't reinvent the wheel and we should contribute commonly used features like image fetching to the open source community.

Reachability - This handles reachability well and I used it for similar reasons as above.
