ImageSearch

This project displays the list of images in scrollable view fetched from the flickr api.

Architecture

The project is based upon MVVM architecture and is written in Swift 4.

• Model - PhotosModel
• View - View in Main.storyboard
• View Model - PhotosViewModel
• Controller - ViewController

Folder Structure

• Data Factory - This is responsible for providing data either fetching remotely thorough the API or from the cache (local DB).
• Extension - This contains swift extensions.
• Constants - This contains all the constants required in the app.
• Custom Views - This contains the custom views created like custom buttons, views, labels, etc.
• Utils - This contains the helper classes.

Configuration

If you want to change the API key used for fetching data through the flickr api, then edit it at Constants -> APIConstants.swift -> APIKey

Unit Tests & Code Coverage

Since the project is based upon MVVM architecture, we can do maximum code coverage by writing unit tests for models, view models, extensions, utils.
