Native iOS App Development —
Swift. SwiftUI. Apple-First.
Native iOS apps in Swift and SwiftUI — for iPhone, iPad, and Apple Watch. Deep Apple framework access: ARKit, Core ML, HealthKit, Apple Pay, and App Clips. Full App Store submission included.
iOS App Development Services
iPhone App Development
Native Swift iOS apps for iPhone — SwiftUI or UIKit, MVVM architecture, Combine/async-await for data flow, and deep integration with iOS frameworks. Full App Store submission handled by us.
iPad App Development
iPad-optimised apps with split-view support, keyboard and Apple Pencil input, and iPadOS-specific multitasking. We design separate iPad layouts in Figma — not just enlarged iPhone screens.
Apple Watch Apps
watchOS apps for health tracking, notifications, quick interactions, and Siri Shortcuts. Standalone watchOS apps that work without the paired iPhone — built with SwiftUI and HealthKit.
ARKit & Augmented Reality
Augmented reality features using ARKit — product try-on (furniture, eyewear, clothing), AR navigation, measurement tools, and marker-based AR. We combine ARKit with RealityKit for 3D rendering.
Core ML & On-Device AI
On-device machine learning with Core ML — image recognition, object detection, natural language processing, and custom model integration. Runs entirely on-device with no server roundtrip.
HealthKit & Fitness Apps
iOS health and fitness apps with HealthKit integration — read and write health data (heart rate, steps, sleep, nutrition), Apple Watch synchronisation, and HealthKit data visualisation.

What Our iOS Clients Say
"Sigill built our iOS fitness app with HealthKit integration, Apple Watch support, and a beautiful SwiftUI interface. It hit 4.9 stars on the App Store in the first month. The attention to iOS design detail is exceptional."
"We needed ARKit product try-on for our eyewear brand. Sigill delivered a flawless AR experience — frames track perfectly to the face even when the user moves. Our iOS conversion rate improved by 22%."
"Complex app — multi-role (doctor, patient, admin), HealthKit, video consultations, and Apple Pay. Sigill navigated Apple's review process on the first submission. The architecture is clean and our internal team can maintain it."
Frequently Asked Questions
Build native iOS (Swift) when: (1) your users are iOS-first and you want the best possible iOS experience, (2) your app needs deep Apple framework access — ARKit, Core ML, HealthKit, Apple Pay, Apple Watch, App Clips, (3) you're targeting the premium App Store audience where iOS-first users convert better. Choose React Native or Flutter when: budget is limited, you need both iOS and Android simultaneously, or your app is primarily CRUD functionality without deep platform integration.
SwiftUI is Apple's modern declarative UI framework — introduced in 2019 and now mature enough for production use. We build all new iOS apps with SwiftUI. SwiftUI is faster to write than UIKit, handles dark mode and accessibility automatically, and enables live previews in Xcode. For apps targeting iOS 15+ (which covers 98%+ of active devices), SwiftUI is the right choice.
A simple iOS app with 6–8 screens and an API backend typically costs ₹3,50,000–₹7,50,000. A mid-complexity app with HealthKit, in-app purchases, or real-time features costs ₹8,00,000–₹16,00,000. A complex app with ARKit, Core ML, or multi-role architecture costs ₹16,00,000+. All projects are fixed-price.
Yes — App Store submission is included in every iOS project. We handle the Xcode archive, TestFlight beta, App Privacy details, screenshots for all required device sizes, and the App Store Connect submission. Apple's review typically takes 1–3 days. We manage any review feedback and resubmission.
Yes — we build ARKit product try-on for fashion (eyewear, hats, jewellery), furniture placement (using LiDAR for room scanning), and cosmetics (lipstick, eyeshadow try-on via face tracking). We use ARKit's face tracking and plane detection APIs, combined with RealityKit for 3D model rendering.
Yes — Apple Pay integration via PassKit is standard in our ecommerce and fintech iOS projects. We implement the full payment flow: Apple Pay button, payment request, authorisation, backend verification, and order confirmation. Apple Pay supports one-tap checkout for users with a payment method already in their Apple Wallet.
Yes — we use StoreKit 2 (the modern API) for in-app purchases and subscriptions. StoreKit 2 has a clean async/await API and handles receipt validation natively — no server-side receipt validation required. We implement consumable purchases, non-consumable purchases, auto-renewable subscriptions, and promotional offers.
An App Clip is a small, instant-load version of your iOS app — accessible via NFC tag, QR code, URL, or App Store search — without requiring the user to install the full app. App Clips are limited to 15MB and specific use cases (payments, rentals, ordering). They're excellent for physical retail (scan to order), hospitality (scan to pay), and event check-in. We build App Clips as a companion to the full app.
A basic SwiftUI app with 6–8 screens and an API backend takes 8–12 weeks. A medium-complexity app with HealthKit, payments, or notifications takes 12–18 weeks. A complex app with ARKit, Core ML, or multi-role takes 18–28 weeks. Sprint builds every two weeks mean you see working iOS builds throughout.
Yes — iOS requires ongoing maintenance because Apple releases major iOS updates annually, each of which may deprecate APIs or change system behaviour. We offer monthly retainer support covering iOS compatibility updates, Xcode and Swift version upgrades, Sentry crash monitoring, App Store review compliance updates, and feature additions.
