FlickerApp

Overview

This is a Demo app that utlize Flicker API to search free images and download them. The goal for this app is to practice several iOS topics like :

Tech Stack

1. Rxswift for the business and UI layer.
2. Callbacks for Networking layer.
3. Kingfisher for Image Operations .
4. UIKit for Interface .

Screens :

Search Screen while Loading	Search Screen	Photo Details Screen

Architecture Design Patter

MVVM Design Pattern

Project Structure

Networking Group

This contain the network layer for the App , in which I tried to follow clean Architecture Principles , so fora each module there is Data and Domain layers. Data Layer : is responsible for defining the Models , Endpoints and Service for the feature
Domain Layer : is responsible for exposing the use cases for the feature into protocols.

Callbacks is used for implementing the API Service and URLSession requests .

Modules Group

This contain the Business and Presentation layer for the App (i.e Screen) , each scree is contained Separately into a Module and decency injection is being used to inject any thing this module would need to work.

• when navigating pass any thing the. module PhotoGallery might need

• when initiating the module , asking it's dependencies

Data Flow :

• MVVM + Rxswift used to mange Data flow

example :

1 . bind UI Component in View Controller

2. In View Model , Do the Logic to get the Data needed , when get it Emit to the Observable to reflect on the collection View

Image Processing :

• Kingfisher is being used for Handling image Downloading and Caching
