Experience

  • Mobile Banking App for 12 Danish Banks

    A native Objective-C and Swift app for iOS and iPadOS. It was an app with 12 different looks but the same code. I developed features, optimized the architecture, and created a fully-automated UI testing setup for the app, which tested both features and the UI. The app is now replaced with a cross-platform app.

  • AppDab | Native macOS App for App Store Connect
    https://appdab.app

    A native macOS app for App Store Connect and the Apple Developer portal that was released in November 2022. The app is written with SwiftUI and uses my open-source library, Bagbutik, to interact with the App Store Connect API.

  • LightTable App for iPad/iPhone
    https://apps.apple.com/us/app/lighttable-by-mogee/id739396908

    An app I created for an illustrator who needed an easy way to draw on a blank paper on top of another drawing. The app lights up the iPad's screen so the underlying drawing can be seen through the top paper.

    Since then, people from other industries have also used the app, e.g., for taking high-resolution photos of negatives.

    The app was originally written in Objective-C but was later converted to Swift.

  • Bagbutik | Swift Client Library for the App Store Connect API
    https://bagbutik.dev

    A generated Swift client library for the App Store Connect API based on the official OpenAPI specification. Bagbutik is two things – a command line tool for generating Swift code, and a library with the generated code for the App Store Connect API. The command line tool decodes the official OpenAPI specification for Apple's App Store Connect API.

  • Fluxor | Unidirectional Data Flow in Swift
    https://fluxor.dev

    When developing apps, keeping track of data flow can quickly become challenging. Data flows in multiple directions and can quickly become inconsistent with multiple sources of truth.

    With Fluxor, data flows in only one direction. There is only a single source of truth, updates to the state are done with pure functions, the flow in the app can easily be followed, and all the individual parts can be unit-tested separately.
