Personal finances app using Starling bank's API with RxSwift + MVVM architecture

Requirements

• iOS 13+
• Xcode 14

Highlights and benefits

• Reactive programming - Declarative programming paradigm concerned with data streams and the propagation of change.
• MVVM architecture - Better application of SOLID principles and encapsulation of components. Offering better testability and flexibility.

Summary

This app currently shows all accounts and will eventually show the balance, overdraft, pending transactions. Atm, it shows one demo account and transitions into a UITabViewController where you can switch between transactions and savings goals.

All network requests and errors are handled by the ViewModel through bindings.

You can create a new savings goal in the savings section.

Changes in the UI and UX will be made along with writing unit tests.
