This proof of concept app which consumes a REST service and displays photos with headings and descriptions to demonstrate some aspect of clean architecture using MVVM pattern, loose coupling, unit testing and some of the best practices used in modern iOS programming using Swift.
- This project was intended as proof of concept app which consumes a REST service and displays photos with headings and descriptions.
- The demo uses the Feeds API which returns information in a JSON format.
- Implemented Unit test for business logic.
- The feed contains a title and a list of rows.
- Restrict the image to go to outside of the device width if image is having a larger width then your device.
- Loads the images lazily and Don’t download them all at once, but only as needed.
- Refresh function
- Each image having title at the bottom of the image.
- Note - Should not block UI when loading the data from the json feed.
- Xcode 11.0(required)
- Clean

No Third Party Librariies used in the Project
- MVVM - My preferred architecture.
- MVVM stands for “Model View ViewModel”
- It’s a software architecture often used by Apple developers to replace MVC. Model-View-ViewModel (MVVM) is a structural design pattern that separates objects into three distinct groups:
- Models hold application data. They’re usually structs or simple classes.
- Views display visual elements and controls on the screen. They’re typically - subclasses of UIView.
- View models transform model information into values that can be displayed on a view. They’re usually classes, so they can be passed around as references.
