iOS App Development Company for Native Swift Apps

Native iOS is the right call when performance, platform features, or App Store trust genuinely matter — not by default. We build with Swift and SwiftUI, ship through App Store review without the usual back-and-forth, and stay on for the updates that come after launch.

Why teams choose a dedicated iOS team over a generalist agency

A native app is a bigger investment than a cross-platform build — it only pays off when the engineering and the App Store process are both handled correctly.

Swift and SwiftUI by default

Modern, type-safe iOS development — no legacy Objective-C bridging unless your existing codebase requires it.

Honest native vs cross-platform guidance

We'll tell you when React Native or Flutter is genuinely the better fit — native isn't the answer for every app.

App Store submission handled end to end

Provisioning, review guidelines, metadata, and rejections managed by people who've shipped through review before.

Built for Apple's platform, not just the phone

Widgets, App Clips, Apple Watch companions, and iPad layouts scoped in when they add real value.

Legacy iOS app rescue

We take over apps built by other vendors — outdated UIKit, missing source control, or code nobody in-house understands.

Senior engineers, not a junior bench

The people writing your app are the people who scoped the architecture — no handoff gap between sales and delivery.

What an iOS engagement typically includes

Scoped to what your product needs — not a fixed package of features you'll pay for and never use.

Native app builds

Consumer and enterprise iOS apps built in Swift and SwiftUI from scoping through App Store launch.

UIKit-to-SwiftUI migration

Modernizing existing UIKit codebases incrementally, screen by screen, without a risky full rewrite.

App Store submission & review

Handling provisioning profiles, metadata, and review rejections so launches don't stall.

Backend & API integration

Connecting your iOS app to REST/GraphQL APIs, push notifications, and third-party SDKs.

Performance and crash audits

Diagnosing slow launches, memory leaks, and crash reports on apps that are already live.

Ongoing maintenance

iOS version updates, new device support, and feature work after the initial release.

FAQ

When you need deep platform integration (widgets, ARKit, background processing), the best possible performance, or a UI that has to feel exactly like Apple's own apps. If you're validating an idea across iOS and Android with a limited budget, cross-platform is often the more sensible starting point.

It depends on scope — a focused single-purpose app costs far less than a product with backend integrations, real-time features, or Apple Watch/iPad companions. We give a fixed estimate after a short scoping call rather than a generic range.

Yes, SwiftUI is our default for new builds. We still work in UIKit for existing codebases or where a specific feature isn't yet well supported by SwiftUI, and we migrate incrementally rather than forcing a rewrite.

Yes. We regularly take over existing iOS apps — auditing the codebase first, then handling updates, bug fixes, and new features without a full rewrite unless the existing code genuinely requires one.

We prepare submissions against Apple's current guidelines to avoid predictable rejections, and if a rejection does happen, we handle the resubmission and the back-and-forth with App Review directly so it doesn't sit on your plate.
