Master_Detail

iOS App that displays a list of users where we can tap and go to user profile.The list of users is cached incase there is no internet.

How to install :

• Make sure you have Xcode 14.3 or above
• Open GeoMobileTask.xcodeproj
• Run project to simulator or real device using cmd + R

Requirement:

• First start of the app: With an existing internet connection the data is displayed in a list. The images are displayed and you can open a detail view. The detail view shows the same data as in the cell with a different layout.
• Second start of the app with a switched off internet connection: The app displays the saved data. The images are not displayed.

App Architecture :

I applied clean architecture in all my modules. you can see that the app is including the following modules:

• API module
• Cache module
• Feature/Domain module
• UI and Presentation module

For the API module I used URLSession to handle the HTTP calls, Of course, the app has been implemented in a way that we can use any framework or third parties like Alamofire.

For the Cache module I used FileManager to cache content, Of course, the app has been implemented in a way that we can use any framework or third parties like Realm or CoreData.

For the Presentation module I used MVVM Design pattern, and I've tried to decouple all my modules using protocols, so you can find that I hide the implementation details by using protocols.

For the Feature/Domain module here the business logic or model for the feature is written which is completely agnostic of the presentation layer and the data layers(api/cache) .

Finally, I composed all the module inside the RootView.

Improvements and feedback:

• Unit Testing for entire app
• add snapshot tests to test ui layout
• add dark mode (✓)
• improve UI for landscape(✓)
• adding refresh control for reloading(✓)
• adding retry incase of failure(✓)
• adding timestamp for user to know when the data was last updated.(✓)
