The stack:

• Programming Language: The vast majority of our code is written in Swift

• Concurrency: We have a large, old, but modular codebase. We use modern Swift Concurrency as much as possible as we gradually move away from RxSwift

• UI code: As much new UI code as possible is in SwiftUI. We fall back to UIKit when needed and re-use the majority of it on macOS using Catalyst

• Cross-platform: We re-use our core packages on cross-platform using SwiftWasm, UI for other platforms is written using React or their respective native APIs

• Dependencies: We exclusively use Swift Package Manager and frequently make new local packages

• Source control and builds: We have a mono-repo and use GitHub and Pull Requests. We kick off builds using a Slack bot

• Continuous Integration: We use CircleCI which means our configuration is checked in with our code. We have unit tests for all of our modules which run on every branch. UI tests are run daily and before release

• Release cadence: We QA and release on a weekly schedule
