Photo-Flickr

Photo-Flickr application written in Swift. This project searches for images using Flickr API and displays in a list and provides endless scrolling. Also, pressing on a image will take you to details page. You can share, save and zoom in/out images. NetworkManager takes care of fetching data from Flickr service. The application uses MVVM architecture.

Technology:

Swift, MVVM, Cocoapods, Kingfisher, Xcode 14.3

Flickr API:

Images are retrieved by hitting the Flickr API.

Features:

1. Home screen: shows a list of searched pictures based on keywords
2. Details screen: shows a selected picture from results screens
3. Searches persisted between launches
4. Save picture in Photos
5. Share picture
6. Zoom in, zoom out
7. Unit tests
8. UI tests

Decisions

• Used MVVM for better testability and separation of concern.
• Used Kingfisher for caching images. So that i don't have to retrieve same images again.
• Used Timer for debounce. So that it reduce repetitive network calls.
• Used UserDefault for persisted between launches. As the app is simple that's why i choose UserDefault instead of CoreData.
