TwitterPlayground

This app utilizes the Twitter Public API to search Tweets, and display trending topics in the users area.

Although this app only has one server it interacts with, by utilizing Endpoint, Router and Interceptor objects, the logic behind reauthenticating and handlind server specific logic is possible, yet still using the same Networking class that performs the network requests via URLSession.

Technologies Used in this app:

1. SwiftUI/Combine
2. PromiseKit
3. CoreLocation

Things to Improve:

1. Networking With the Twitter Interceptor object, it re-authenticates after getting a 401, then retries the request. Right now there is no check to see if it has already gone through this flow when making a request. This means that if a server for whatever reason fails to authenticate, or continues to throw a 401, the app will recursively keep making these network requests. This is not shippable, it needs to be resolved.

2. UI The UI for this app was done while keeping on eye on my kids in the bath, so naturally there is room for improvement. Fortunately this app was never intended to showcase my SwiftUI skills so I let that slide.

3. Error Handling Currently if there is an error returned from any of the requests it is not displayed to the user. On the Trends screen if the user does not give consent to share location data it will not prompt again.

4. Unit Tests Again, wasn't the priority but would be good to have.
