    Native iOS is the right call when the app's quality bar is "feels like it was made by Apple" — smooth gesture handling, correct Human Interface Guidelines behaviour, and same-day access to whatever API Apple ships at WWDC. Cross-platform frameworks close that gap for most product categories, but for apps competing on polish or leaning on cutting-edge Apple frameworks, the native build is worth the dedicated codebase.

    Swift and SwiftUI, with UIKit where it earns its place

    We build new iOS apps in Swift with SwiftUI as the default UI layer — Apple's own direction since 2019, and the fastest path to shipping adaptive layouts across iPhone, iPad, and beyond. UIKit still shows up where SwiftUI's component library has gaps or where a client's existing codebase is UIKit-based and a full rewrite isn't warranted; we mix the two deliberately rather than forcing one paradigm where it doesn't fit.

    Architecture and testing

    We build with MVVM for most projects and TCA (The Composable Architecture) for apps with complex, highly stateful flows where TCA's unidirectional data flow pays for its extra ceremony. Either way, business logic is kept independent of the view layer so it can be unit tested without booting a simulator. UI and integration tests then run against real device configurations in CI, catching layout and gesture regressions before they reach TestFlight.

    Why native

    Why Choose Native iOS Development?

    Native Swift & SwiftUI

    Modern iOS development with Swift and SwiftUI. Clean architecture, async/await concurrency, and Human Interface Guidelines — apps that feel at home on Apple hardware.

    Apple Ecosystem Integration

    ARKit, Core ML, HealthKit, Sign in with Apple, Apple Pay, Face ID — we integrate the full Apple platform API surface, not just the basics.

    iPhone, iPad & Beyond

    Universal apps with adaptive layouts for every screen size, plus watchOS, tvOS, and Mac Catalyst. One codebase built to scale across the Apple ecosystem.

    App Store Ready

    We handle App Store submission, review guideline compliance, TestFlight beta testing, and ongoing updates — including Apple OS version compatibility every September.

    How we work

    Our iOS Delivery Process

    1. 01

      Discovery & Technical Scoping

      We map your feature set against the iOS APIs it needs, agree on minimum supported iOS version, and produce a binding project charter with fixed timeline and milestones.

    2. 02

      Architecture & UI Build

      MVVM or TCA depending on complexity, with SwiftUI as the default UI layer and UIKit where its component library still leads — built out screen by screen against your design system.

    3. 03

      Apple Framework Integration

      ARKit, Core ML, HealthKit, Sign in with Apple, Apple Pay, and Face ID are wired in and tested across a device lab spanning current and prior-generation hardware.

    4. 04

      QA, TestFlight & App Store Submission

      Automated tests run in CI on every PR; TestFlight beta builds go to your stakeholders before submission. We handle App Store review, then hand over the repo and CI access.

    FAQ

    iOS Development FAQ

    A native iOS MVP covering core features typically takes 8–12 weeks from design kickoff to App Store submission. A more complex iPhone or iPad app with custom integrations, real-time data, and payment flows takes 14–20 weeks. We work in two-week sprints so you see a working build throughout development, not just at the end.

    We build for iPhone, iPad (universal apps with adaptive layouts), and the full Apple ecosystem including Apple Watch (watchOS), Apple TV (tvOS), and Mac (macOS via Mac Catalyst or native SwiftUI). Most of our clients start with iPhone and we expand to iPad and other platforms in later phases.

    We build with Swift as the primary language and SwiftUI for modern declarative UI, with UIKit for components that require it. Architecture-wise we follow MVVM or TCA depending on project complexity. For networking we use URLSession/Combine or Swift Concurrency, for persistence SwiftData/Core Data, and for backend connectivity REST APIs, GraphQL, WebSockets, and Firebase.

    Native iOS (Swift/SwiftUI) gives you the best performance on Apple hardware, full access to the latest iOS APIs (ARKit, Core ML, HealthKit, Vision), and the tightest integration with the Apple ecosystem. If you need iOS and Android simultaneously on a tighter budget, Flutter or React Native are strong alternatives. We build all three and help you choose based on your product requirements.

    A native iOS MVP typically runs $25,000–$45,000 over 8–12 weeks. A growth-stage app with payments, real-time features, and custom integrations runs $45,000–$90,000 over 14–20 weeks. Enterprise builds with watchOS, ARKit, or complex system integrations start at $90,000. Every quote is fixed-scope after a free discovery call, itemised by feature.

    We build against Apple's current App Store Review Guidelines from the first sprint — privacy manifests, tracking transparency prompts, and in-app purchase rules are handled up front rather than retrofitted at submission time. TestFlight beta builds go out to your stakeholders before we submit, so the version Apple reviews has already been used by real people.

    Yes. We typically migrate screen by screen behind a feature flag rather than a full rewrite, so the app stays shippable throughout. We start with an audit to flag which screens have SwiftUI-incompatible dependencies (custom UIKit gesture recognizers, older third-party SDKs) and sequence the migration to touch those last.

    Need both platforms?

    Need Android Too?

    If you need iOS and Android simultaneously, Flutter lets us share 90%+ of the codebase without sacrificing quality. We also build native Android separately. We'll help you choose the right approach for your timeline and budget.
