Native craft for Apple’s platform
iOS users notice jank, broken accessibility, and privacy surprises—and App Review will too. NASBIX builds Swift apps with SwiftUI or UIKit, clear architecture, and release pipelines that survive review cycles and OS upgrades.
From Karachi HQ we deliver for brands and product teams who need transparent sprints and apps ops can support after launch. Named architects stay close to Apple edge cases—IAP, Sign in with Apple, background modes, and privacy manifests—so design and engineering share one release train.
- SwiftUI or UIKit—matched to your team and feature set
- Apple frameworks: push, Wallet, HealthKit, and maps where scoped
- TestFlight betas, review notes, and metadata checklists
- Handovers your iOS squad can extend without a rewrite
