Your assignment is to implement an app displaying exchange rates for iOS devices.
You won a lot of money by betting on the outcome of the European Football Championship, and now you are thinking about how you can increase long-term revenue (after spending quite a bit on a big party, of course). After diving into different investment strategies, you decide that you are going to try currency trading. And because you're a software developer, after all, creating an app that helps with that is a no-brainer - so you come up with XRate, the exchange rate helper on iOS.
This assignment aims to build an app that shows a list of exchange rates using the exchange rates API and allows to view historical data by clicking on any of the exchange rates.
- Allow entering a base currency on the home screen from a list of currencies by searching
- Show live exchange rates using the exchange rates API (the order of the currencies does not matter) based on the selected base currency
- Implement a detail-view for each exchange rate displaying historical data of the last 52 weeks
- Allow marking a currency as favorite in the details view and show the favorites on the very top of the list
- Persist the entered base currency and favorites
- If you have time left: Surprise us! Add a feature that you think would work well here (for instance, allow selecting a different timespan in the details view)
- Make sure to include all source code in this repository.
For iOS, include a assignment.zip file containing your compressed .app bundle in the root of the repository. Your .app bundle must represent a simulator build of your app. After running in iOS Simulator via Xcode, look in ~/Library/Developer/Xcode/DerivedData//Build/Products/Debug-iphonesimulator/. Alternatively, you may run xcodebuild -sdk iphonesimulator (if you use .xcodeproj) or xcodebuild -sdk iphonesimulator -workspace Sample.xcworkspace/ -scheme -configuration Debug (if you use .xcworkspace) in your project directory, then zip the .app bundle in build/Debug-iphonesimulator/.
- iOS + SwiftUI best practices
- Architecture and Scalability: is it laid out in a scalable way and uses common patterns in mobile development?
- Correctness: does the functionality act in sensible, thought-out ways?
- Maintainability: is it written in a clean, maintainable way?
- Testing: is the system adequately tested?
- We're looking for you to produce working code, with enough room to demonstrate how to structure components in a small program
It is not important to aim for 100% completeness. We prefer well-built, tested, and scalable features over half-baked solutions.
Please organize, design, test and document your code as if it were going into production - then push your changes to the master branch. After you have pushed your code, you may submit the assignment on the assignment page.
All the best and happy coding,
The VitraCash Team
