A new App named WorldOfPAYBACK is planned to be released. One of its first features involves displaying a list of transactions, and a corresponding detail screen for each.
Please create a SwiftUI App based on the following User-Stories:
- As a user of the App, I want to see a list of (mocked) transactions. Each item in the list displays
bookingDate,partnerDisplayName,transactionDetail.description,value.amountandvalue.currency. (see attached JSON File) - As a user of the App, I want to have the list of transactions sorted by
bookingDatefrom newest (top) to oldest (bottom). - As a user of the App, I want to get feedback when loading of the transactions is ongoing or an Error occurs. (Just delay the mocked server response for 1-2 seconds and randomly fail it)
- As a user of the App, I want to see an error if the device is offline.
- As a user of the App, I want to filter the list of transactions by
category. - As a user of the App, I want to see the sum of filtered transactions somewhere on the Transaction-list view. (Sum of
value.amount) - As a user of the App, I want to select a transaction and navigate to its details. The details-view should just display
partnerDisplayNameandtransactionDetail.description. - As a user of the App, I like to see nice UI in general. However, for this coding challenge fancy UI is not required.

Attached you will find a JSON File (
PBTransactions.json) which contains a list of transactions. Just assume that the Backend is not ready yet and the App needs to work with mocked data meanwhile. For now, the Backend-Team has just provided the name of the endpoints for the new Service:- Production Environment: "GET https://api.payback.com/transactions"
- Test Environment: "GET https://api-test.payback.com/transactions"
-
The App is planned to be maintained over a long period of time. New Features will be added by a growing Team in the near future.
-
The App is planned to be available worldwide supporting many different languages and region related formatting (e.g. Date and Number formatting).
-
The Feature you are currently working on is the first out of many. Multiple Teams will add more features in the near future (overall Team size is about 8 Developers and growing). The following list of Features (which are not part of this coding challenge) will give you an idea of what's planned for the upcoming releases.
- "Feed"-Feature: Displays different, user-targeted content (displayed via webviews, images, ads etc.). Note: It is also planned to display the sum of all Transactions from the "Transaction"-Feature.
- "Online Shopping"-Feature: Lists PAYBACK Partners and gives the possibility to jump to their App/Website.
- "Settings"-Feature: Gives the possibility to adjust general Settings.
- We are currently in a transition phase of moving from UIKit to SwiftUI.
- We use Reactive programming and are currently moving from a self built Reactive-Library to Combine. For asynchronous code we are moving to Swift Concurrency.
- We try to keep to as few external dependencies as possible. However, we use Swift Package Manager when we need to add a dependency.
- We are using Jenkins to build, test and deploy our Apps.
