iOS

Native iOS applications, engineered for App Store review and the ten-year arc.

Start a build
The argument

An iOS app is just a promise, kept with the platform.

Each view · a contract. Each modifier · a decision. Each release · a promise kept.
02 — Ecosystem

iOS,
and the right neighbours.

UI framework/01
SwiftUI

Declarative views, state-driven layout, and native platform behaviour out of the box. Our default for new screens.

DeclarativeState-drivenMultiplatformiOS 17+
Interop/02
UIKit

Legacy screens, custom transitions, and fine-grained control when SwiftUI isn't enough yet.

LegacyBridging
Concurrency/03
Swift Concurrency

async/await, actors, and structured task trees replace callback pyramids.

async/awaitActors
Reactive/04
Combine

Publisher/subscriber pipelines for streams, bridging legacy delegates into SwiftUI state.

PublishersBindings
Persistence/05
SwiftData / Core Data

Type-safe local models, migrations, and offline-first storage.

Local storeMigrations
Sync/06
CloudKit

Cross-device sync backed by iCloud, no custom backend required for simple state.

iCloudSync
Payments/07
StoreKit 2

Subscriptions, one-time purchases, and receipt validation without server round-trips.

IAPSubscriptions
Messaging/08
Push · APNs

Silent pushes, rich notifications, and background refresh done right.

PushBackground
Widgets/09
WidgetKit

Home screen widgets and Live Activities that keep the app present without being open.

WidgetsLive Activities
On-device ML/10
Core ML

On-device inference for classification, vision, and personalization — private by default, no network round-trip.

CI/CD/11
TestFlight + Xcode Cloud

Automated builds, beta distribution, and crash-free release gates.

09 — Questions

Things people
actually ask.

SwiftUI by default: less code, native platform behaviour, and it's where Apple is investing. We drop into UIKit for legacy screens, custom transitions, or fine-grained control SwiftUI still can't reach — usually bridged via UIViewRepresentable, not a full rewrite.
We build against current App Review Guidelines from day one — privacy manifests, tracking disclosures, IAP compliance — and submit a TestFlight build early to catch rejections before they're expensive. Most of our clients' first submissions pass without a resubmission cycle.
Yes, when it's in scope. SwiftUI's adaptive layout gets iPad mostly free if the app is built with size classes in mind from the start; Mac Catalyst is a deliberate decision we scope separately, since desktop interaction patterns need real design attention, not just a bigger canvas.
SwiftData or Core Data as the local source of truth, with a sync layer that reconciles against the backend — optimistic writes, conflict resolution, and background refresh. The UI reads from the local store first; the network is an implementation detail, not a dependency for basic use.
Figma for flows and visual direction, but the source of truth is a token set mapped to SF Symbols, Dynamic Type, and our SwiftUI design system — not a static export. Designers and engineers review the same Xcode Previews; there is no "design version" of the truth.
You do. The repo, the App Store Connect account, the signing certificates — all under your organization from day one. Work is delivered under a work-for-hire clause; we keep no embedded SDKs or licensing strings attached.

something worth shipping.

Two-week diagnostic, four-week MVP, twelve-week ground-up. Bring the brief — we'll send a plan, not a pitch deck.
