How we use Swift
Interfaces are written in SwiftUI, with UIKit brought in where a control needs precise behaviour, such as custom text editing or complex gestures. Concurrency uses async and await, so network and database work stays off the main thread and scrolling stays smooth.
For productivity apps the system extensions matter as much as the app itself: home-screen and lock-screen widgets, Siri shortcuts and notifications that open the right screen. Paid features are handled with StoreKit 2, which verifies purchases on the device and keeps subscription status up to date.
What we build with it
- Native iPhone and iPad apps with SwiftUI
- Widgets, App Intents and notification actions
- In-app purchases and subscriptions with StoreKit 2
- Local data with SwiftData or Core Data and iCloud sync
Toolkit
- SwiftUI

How we keep Swift code healthy
- SwiftLint in the build pipeline
- Unit and UI tests run in Xcode Cloud or CI
- Accessibility checked with VoiceOver and Dynamic Type
- Instruments used to profile memory and launch time
Questions about Swift
SwiftUI or UIKit?
SwiftUI for new screens. UIKit where SwiftUI still lacks control or when the app already has a large UIKit codebase.
Do you build for iPad and Apple Watch too?
iPad layouts are part of iOS projects when the brief includes them. watchOS apps are scoped separately.
