How to run the application

• Download Xcode
• Clone this repository
• Navigate to Config.xcconfig and put your API key instead of <API_KEY>. More information can be found here.

Code structure

The code follows the MVVM architecture and the navigation is handled by a coordinator.

It is organized in a few folders:

• API API integration.
• Categories Categories extending existing functionality
• Coordinators Coordinators handling navigation
• Helpers Classes for supporting functinality
• Model Data models
• ViewControllers ViewControllers
• ViewModels ViewModels
• Views Custom views

CoreData is used to save downloaded images from the app as Data for faster loading when possible.

Note: The above image cashing machanisim is not suggested or optimal. Especially considering that right now it does not clear the saved data. It was implemented with the sole purpose of demonstrating the usage of CoreData. A more suitable solution could be using a framework like SDWebImage.
