What we build

End-to-end iOS capabilities

Native Swift, built to Apple standards

Swift and SwiftUI for iOS apps integrated with the platform. When an Android app is also needed, we compare native implementations with Flutter based on requirements, integrations and maintenance.

Native Swift modules

HealthKit integrations, ARKit scenes, home screen widgets, watchOS complications and Siri shortcuts — when a feature genuinely requires Swift, we write a clean module through a platform channel and connect it to the Flutter layer without exposing the complexity.

App Store submission and review management

We prepare builds, metadata, presentation materials and privacy information within the agreed scope. We assess store feedback; fixes and resubmission follow the established responsibilities. Approval rests with Apple.

UI aligned with Apple HIG

Apple’s Human Interface Guidelines are not a checklist for the end — they shape component choices from day one. SF Symbols, Dynamic Type, safe-area awareness and faithful dark mode support are built in, not added later.

TestFlight beta pipelines

We prepare beta distribution through TestFlight and feedback scenarios. Release frequency, test groups and publication approval are established within the project.

Performance and battery profiling

Instruments sessions before every release — catching frame drops, memory pressure and excessive wake-lock usage before the App Store reviewer sees them. We optimize for the mid-range iPhone in your target market, not the latest Pro.

Native Swift or Flutter?

The honest answer depends on your situation

We choose between Swift and Flutter based on platform features, integrations, devices and the team that will maintain the product. Shared code does not remove the need for separate testing on each platform.

You also need Android
Flutter

Flutter allows code sharing between iOS and Android. We check native modules, interface differences and testing before estimating cost and timeline.

Advanced ARKit or visionOS features
Native Swift

Scene reconstruction, Reality Composer Pro assets and visionOS spatial APIs have no straightforward Flutter equivalent. We build natively.

An existing Swift codebase to extend
Native Swift

Rewriting a working Swift app in Flutter to add features introduces risk without a gain. We extend what you already have.

Limited budget, both stores
Flutter

We compare the cost of the whole project: apps, backend, integrations, testing and maintenance. Savings depend on requirements; we do not use a universal percentage.

Technology stack

The iOS toolchain we actually use

Swift and SwiftUI are our native iOS layer. Flutter and Dart when a shared iOS and Android codebase is a good fit. Xcode and TestFlight in the CI pipeline, App Store Connect for delivery.

We do not use Xamarin, Ionic or Cordova. If a project is better served by cross-platform Flutter than native Swift, we say so before you commit — not six months later.

FAQ

Frequently asked questions

Can we start without technical specifications?

Yes. We start with your business objectives and existing systems. We define requirements and architecture with your team, then deliver in stages. If the scope is already clear, we can start directly with implementation.

Native Swift or Flutter for our iOS app?

Swift is suitable when integration with iOS features or existing code justifies it. Flutter may suit a shared iOS and Android product. We evaluate devices, native modules, performance and maintenance before making a recommendation.

How do you handle App Store review and rejections?

We prepare the app and materials for review. If a rejection occurs, we analyze the reason and identify the explanations or changes required. The timeline, cost and resubmission depend on the project scope or support agreement; approval rests with the store.

We only need iOS — native Swift or Flutter?

For iOS-only products, native Swift is often the best choice — the deepest platform integration and no cross-platform layer to maintain — and it is our specialty. Flutter makes sense if you may expand to Android later, want a faster build loop or have a tighter budget. We recommend native development when the product relies on OS-level features or an existing Swift codebase, and Flutter when reach and speed matter more. The right tool for your project wins, not our personal preference.

Can you take over an existing Swift app?

Yes. We start with a codebase audit — architectural health, dependency freshness, test coverage and any App Store compliance issues. From there, we can take on maintenance, add features in place or, where it makes sense, plan a gradual migration to Flutter. We give you an honest assessment of what the codebase needs before committing to a scope.

How long does it take to deliver an iOS app?

For a first production release, the benchmark is two to four months, depending on scope and dependencies. Integrations, backend, data access and checks can change the plan. The schedule accounts separately for beta distribution and store review; approval time is not guaranteed.

Looking for an iOS app development company?

We start with a free 30-minute discussion about objectives and constraints. Detailed analysis, solution design and estimates are agreed separately.
