Our application is in the top chart of finance apps in the UK, with over 300K ratings and an average rating of 4.9. Our iOS application is entirely written in Swift. It is highly modular and we use MVVM-C architecture to maximise code reusability and testing. We also value simplicity over complexity, fewer moving parts means fewer faults and easier comprehension. Some of the well known frameworks and tools we use: RxSwift - as our reactive programming framework; SnapKit - as our auto layout DSL, though we have an in-house framework built on top of SnapKit which allows us to write declarative, SwiftUI like layout code for UIKit. Realm - as the application main persistence layer; Sourcery and SwiftGen - for various code generation tasks. SwiftFormat, SwiftLint and Danger - to enforce high code quality standards. Etc. We also built in-house tools and frameworks as developer productivity and automation is paramount to us. We are looking for iOS engineers to work on these apps who: Want to work on a feature rich mobile app with millions of customers; Can produce robust, well tested code that will give our customers the reliability that they need; Care about the product, the user experience and the design; Think (like us) that a small number of empowered developers is the right way to deliver software; Our application is built with UIKit, knowing its concepts and components is a must.
