The take-home project requires us to begin with a UIKit skeleton project, and it is designed to be compatible with iOS 14 and above. However, the majority of its implementation, approximately 90%, is built using SwiftUI. I have also worked with UIKit for six years, but I believe that declarative programming, such as SwiftUI, offers Simplicity and Readability.

Implemented Requirements

The following requirements have been implemented:

• Save/Load City: The project supports saving and loading city data.
• Location Permission Handling: The app handles location permission requests and interactions.
• Background Location Toggle: The app handles toggling location updates while it is running in the background.
• Image Cache with URLCache: Image caching is implemented using URLCache for improved performance.
• UI Support for Portrait and Landscape: The user interface adapts and supports both portrait and landscape orientations.
• Preview Support in Xcode: All views in the project are designed to support previewing in Xcode.

Additional Features

In addition to the implemented requirements, the project includes some noteworthy features:

• Generic Endpoint Response Handling: The project leverages Swift Generics to handle fetching different response types from endpoints, allowing for flexibility and reusability.
• Async/Await for Concurrent and Asynchronous Tasks: Async/await functionality is utilized to manage concurrent and asynchronous tasks effectively.
• Using Combine to Buffer User's Search Typing for Sending query request: Utilizing Combine's debounce operator to delay query requests based on the user's search typing.

Potential Improvements (With More Time)

Given more time, the following improvements and additions would be made to the project:

• Additional Testing and Error Handling: Enhanced testing and error handling would be implemented to ensure robustness and reliability.
• Unit Testing: Unit tests would be developed to validate the behavior and functionality of the codebase.
• Improved Preview Mocks: Enhancements to preview mocks would be made to provide more accurate representations of the app's appearance and behavior.
