Autodoc

A test assignment for Autodoc: an iOS app that displays a news feed with paginated loading.

Requirements

Paginated loading and display of news
All requests use async/await
Optimized for iPad
No third-party libraries
Minimum iOS version — 16.0, Swift — 5.10
UIKit, layout in code
Use DiffableDataSource instead of the legacy UICollectionViewDataSource
Use a state in the ViewModel instead of boolean flags
Cache must not be reset when the app goes to background
Data source: https://webapi.autodoc.ru/api/news/1/15 (the first number is the page, the second is the number of items per page)

UIKit — layout entirely in code, no Storyboard/XIB
MVVM — separation of UI and business logic
Combine — reactive bindings between the ViewModel and the ViewController
State — a single screen state instead of a set of boolean flags in the ViewModel
UICollectionView + CompositionalLayout — flexible and adaptive feed layout
DiffableDataSource — safe animated updates without manual index calculations
Background URLSession — background loading of images and data without third-party libraries
Caching — the cache persists when the app goes to background (disk + memory)
Pagination — paginated loading of news as the user scrolls
Dark Mode — support for light and dark themes
Localizable — string localization via Localizable.strings
Tinted icon — icon with tint color support
async / await — all network requests use structured concurrency
WKWebView — opening the full news article on cell tap
