iOS App Development Company for Custom Apps

Three signals favor native. First, you need Apple-platform features (Live Activities, Widgets, App Clips, HealthKit, CoreML, visionOS) where cross-platform frameworks don't or barely support them. Second, native feel and pixel-perfection matter more than sharing code across platforms. Third, you're iOS-only this year but plan multi-platform later; native buys validation time before cross-platform costs hit. Otherwise, React Native or Flutter with native modules handles 80% of use cases. We build all three. The choice depends on your app, not our preference.

Senior iOS engineers run $160 to $220/hour in the US and UK, $100 to $150/hour in India. A Swift 6 MVP with 15 to 25 screens, auth, and push takes 10 to 16 weeks. A full production app with Live Activities, Widgets, Clips, HealthKit, in-app purchases, and CloudKit runs 14 to 22 weeks. An iPhone + iPad + visionOS build from one codebase runs 16 to 26 weeks. A 2-week readiness audit is refundable. Scoped quote in 48 hours.

SwiftUI for new builds, always. SwiftUI is production-ready now. It handles navigation, scaled lists, collection layouts, animations, custom shapes, and platform surfaces (Widgets, Live Activities, visionOS) that UIKit doesn't touch. UIKit still wins in a few edge cases: very complex collection views needing fine-grained reuse, legacy UIKit codebases where mixing costs more than it saves, and some framework integrations not yet updated. For new builds: SwiftUI first, UIKit only where proven necessary.

You'll need Apple Developer Program membership ($99/year) under your legal entity. App Store Connect app record. Provisioning profiles and signing certificates (we handle these). App icons in every required size. Screenshots for every device you claim to support (iPhone 15 Pro Max, iPhone SE, iPad Pro 12.9, iPad Pro 11).

App Privacy label, Data Safety disclosure, privacy policy URL, support URL, and a Review contact are required too. First submissions take 1 to 3 days. Rejection rates have climbed since 2024's stricter guidelines. We run a pre-check before submit to catch common failures: account deletion flow, subscription disclosures, privacy manifest.

StoreKit 2 is the default for any new iOS build. It's Swift-first, async/await-native, and uses JWS-signed receipts verified directly, so no third-party validation service needed. We implement subscriptions, one-time and consumable purchases, intro and promotional offers, and family sharing. Backend validation uses Apple's App Store Server Notifications V2 for real-time events. For brands shipping across platforms (Apple, Google Play, web), we abstract the purchase layer so subscription logic works everywhere.

Yes. For universal apps (iPhone + iPad + visionOS), SwiftUI lets us share most code with platform-specific adaptations via conditional modifiers. iPad gets split view, slide over, sidebar navigation, pointer interactions, and keyboard shortcuts. visionOS adds 3D volumes, spatial audio, and Look-to-Dwell. We scope visionOS as an add-on when your use case fits spatial computing.

Swift 6 strict concurrency is non-negotiable for new builds. We enable complete concurrency checking from day one, use @Sendable and @MainActor correctly, and design data layers around actors. Async/await is the default for all I/O.

The first two weeks include a concurrency architecture pass where we decide which actors own which state. Teams new to Swift 6 may find this slower at first, but the payoff is zero data races and a codebase that compiles cleanly on every future Swift version.

You do. Apple Developer Program membership under your legal entity. Signing certificates and provisioning profiles stay in your developer account; we're added team members, removable anytime. GitHub repository under your organization from day one. TestFlight and App Store Connect access under your control. On exit: credentials rotated, repo transferred, CI documented, and 30 days of support. No lock-in.
