The application consists of two screens:

• a list of all products
• product details view after clicking on the chosen product with a collection view for all pictures.

• Tools:
  • Xcode 14.3.1
  • minimum supported iOS version - iOS 14

1. Open Flowery.xcodeproj file.
2. Paste your API key generated on the Plant API website in a file AppConstants.swift
3. Run the project.

• Image Caching - using NSCache, so that images wouldn’t be downloaded each time but cached and reused if possible.
• Image Downloading Logic - each cell downloads an image separately and cancels a task if it’s not needed. In the details view the logic is similar - the images are being downloaded one by one instead of all at once.
• Pull to refresh - on the main screen there is a possibility to refresh the content by pulling a table view.
• Logging functionality
• Universal API logic & flow ones

Disclaimer: lots of things inside the code and features could be improved! Some are mentioned in the comments in code for the sample application purposes. Others could be: pagination, more data, etc.
