iOS Development Services

What is iOS development at TPC?

iOS development means writing Swift against Apple's first-party frameworks, targeting iPhone, iPad, Mac (via Mac Catalyst or native AppKit/SwiftUI), and where it makes sense, watchOS and visionOS. We design for the human interface guidelines, use system controls by default, and only build custom components when there is a real reason. The result is an app that respects the platform — dynamic type, dark mode, accessibility, on-device privacy, and handoff between devices all work without bolt-on effort.

We treat the App Store listing, the privacy manifest, the App Store Connect metadata, and the support URL as part of the engineering surface, not an afterthought handed to marketing.

When you need this

Hire us for iOS work if you have a product idea that genuinely benefits from being on the device — offline-first capture, sensors, widgets, Shortcuts, Live Activities, focus filters, or App Intents — or if you have a web product that needs a real iOS companion. We are also a good fit for indie founders who want a single team that can take a SwiftUI prototype to a paid app on the Store without handing off four times.

We are not the right team if you want a thin webview wrapper or a cross-platform Flutter app — those are different jobs and other firms do them well.

Our approach

We start with a working build in TestFlight inside the first two weeks, even if it does very little. From there every week produces a new build, a written changelog, and a short loop of real-device testing. We use Xcode's built-in scheme management, archive and upload from CI, and treat provisioning profiles and signing certificates as code — checked, automated, and reproducible.

We bias toward SwiftUI for new work, drop into UIKit when a screen demands it, and write tests against the parts of the app that actually have logic (state machines, sync, payments) rather than chasing coverage on view code.

Tech stack we use

Language & UI: Swift 6, SwiftUI, UIKit where needed, AppKit for Mac-native surfaces.
Concurrency: async/await, structured concurrency, Combine for legacy reactive code.
Persistence: Core Data, SwiftData, CloudKit sync, GRDB for SQLite-heavy needs.
Commerce: StoreKit 2 for IAP and subscriptions, App Store Server Notifications v2 for server-side receipt verification.
Distribution: TestFlight, Xcode Cloud or GitHub Actions + Fastlane, App Store Connect API for automated metadata.

Typical engagement

A first-version iOS engagement usually runs eight to sixteen weeks. The first two weeks produce a TestFlight build with the spine of the product. The next six to twelve add real features, settle the data model, wire up payments if the product needs them, and harden for App Review. We submit to the App Store ourselves, respond to reviewer feedback, and stay on through the first point-release.

Examples of work

Focus: Forge is our own SwiftUI app for iOS and macOS — a focused task and project tool built around a small set of opinionated primitives, with CloudKit sync, Shortcuts and App Intents support, and a Mac menu bar companion. The same codebase powers both platforms with platform-specific affordances where they matter.

What we don't do: React Native apps, Flutter apps, Cordova/Ionic projects, jailbreak tweaks, or anything that asks us to maintain a Swift codebase still stuck on Xcode 12.
