Tech Stack
Our tech stack is Swift and SwiftUI on a modular Swift Package architecture, using MVVM with @Observable and protocol witnesses for dependency injection. We're actively moving towards Swift 6 and strict concurrency, with async/await replacing our remaining reactive code. We use GraphQL with Apollo, Swift Testing, and ship through GitHub and Xcode Cloud, with Sentry, Rudderstack and Amplitude for monitoring, analytics and experimentation. AI-assisted development is part of how we work day to day, and we continuously evolve our stack to stay up to date and effective.
