Native iOS Apps Built to Perform & Convert
We build iPhone and iPad apps in Swift and SwiftUI, clean architecture, smooth performance, and App Store approval handled. From MVP to enterprise-scale iOS products.
What We Build for iOS
Native iOS development gives your app full access to Apple's ecosystem. ARKit, HealthKit, CoreML, Siri, Apple Pay, and every hardware sensor the iPhone offers. Swift and SwiftUI let us build apps that feel genuinely native, not cross-platform compromises.
We handle the full lifecycle: architecture design, UI implementation, backend integration, App Store submission, and post-launch updates. Every iOS app we build is reviewed for App Store compliance before submission to maximise first-pass approval.
Production Swift since 2015. SwiftUI for modern declarative UIs with smooth animations and accessibility built in from the start.
We know Apple's review guidelines. Every submission is checked against current requirements before upload, minimising rejection risk.
Performance-tested using Xcode Instruments. Memory leaks, battery drain, and scroll performance addressed before release.
REST, GraphQL, WebSocket, and Apple's native services (CloudKit, Push Notifications, Sign in with Apple) integrated cleanly.
Full iOS Development Coverage
Everything your iOS app needs, end to end.
Modern declarative UI with SwiftUI or UIKit for legacy compatibility. Responsive layouts, dark mode, Dynamic Type, and accessibility from the first sprint.
Sign in with Apple, Face ID / Touch ID, Keychain storage, App Transport Security, and certificate pinning for security-sensitive apps.
StoreKit 2 integration for one-time purchases, subscriptions, consumables, and family sharing. Sandbox-to-production testing included.
APNs integration via Firebase or direct, rich push notifications with media attachments, notification extensions, and background refresh.
Firebase, Amplitude, or Mixpanel event tracking. Crashlytics or Sentry for real-time crash monitoring. Custom funnels and retention dashboards.
Native Apple backend integration for sync across devices. CloudKit for structured data, iCloud for document and preference sync.
How We Build Your iOS App
A structured process from brief to App Store.
Requirements gathering, user journey mapping, tech stack decision, and wireframe review before any code is written.
High-fidelity Figma designs following Apple's HIG. Interactive prototypes for stakeholder review before development starts.
Two-week agile sprints. TestFlight build at the end of every sprint for client review and QA.
Functional, performance, and device compatibility testing. App Store compliance sweep before submission.
App Store submission, release management, post-launch monitoring, and update cycles.

Why Studios Choose Us for iOS
Swift experience that goes beyond basic app delivery.
We adopted Swift when it launched and have never looked back. Our codebase quality reflects years of real production Swift, not migrated Objective-C.
Beyond basic Swift. ARKit, HealthKit, Core ML, StoreKit 2, CloudKit, and every Apple framework your app might need. We know which tools to reach for.
We review every submission against current App Store guidelines before upload. Our first-pass approval rate is significantly above the industry average.
Apps that scroll at 60fps, launch in under 2 seconds, and pass Instruments profiling before they ship. Performance is tested, not assumed.
