Task summary

The application is written using Xcode 14 and Swift 5.

The application architecture is MVVM.
Combine framework is used for data bindings between ViewModel and View and for Repositories.
Realm is used for caching albums data.
URLSession is used for loading albums feed and async image loading.
Used dependency manager is CocoaPods.
UI is built completely from code using UIKit and view anchors for layout.
Simple Coordinator is added for application navigation and dependency injections, no storyboards or nibs are used.
Albums list screen is built using CollectionView with Compositional layout and Diffable data source. Refresh control was added to allow the user to reload the data. In case of no internet connection alert is shown.
I’ve decided not to add ViewModel for the album details screen because there is no business logic on that screen.
For data gathering, Local and Remote repositories are used.
To simplify work with the layout I’ve added the extension to UIView that have common methods for layout that were used in the development.
Date helper class was added to handle work with Date.
