iOS App Development Services

NATIVETO THELAST PIXEL

We design and build native iPhone and iPad apps in Swift and SwiftUI for companies whose product depends on Apple hardware, platform features or the feel only a native app delivers.

01Our Approach

We build iOS apps the way Apple intends them to be built, so new system features arrive as small additions rather than rewrites.

02Overview

Native iOS apps that feel at home

  • 01Swift and SwiftUI
  • 02App Store releases
  • 03Apple framework integrations

Native iOS development covers iPhone and iPad apps written in Swift, along with widgets, App Clips, Apple Watch companions and the App Store work around them. It is the right choice when your audience is mostly on Apple devices, or when the product relies on HealthKit, ARKit, Apple Pay, background processing or animation quality that cross-platform frameworks handle less well.

We follow Apple's Human Interface Guidelines and build with SwiftUI first, using UIKit where a screen needs finer control. Dynamic Type, VoiceOver and dark mode are part of the first build, since adding them later costs more. Releases go through TestFlight to real testers, and we handle signing, privacy declarations and App Review so submission is not a surprise at the end.

03What We Do

Capabilities, End to End

01
SwiftUI interfaces

Screens built in SwiftUI with UIKit where needed, supporting Dynamic Type, dark mode, iPad layouts and the navigation patterns iPhone users already know.

02
Apple framework integrations

HealthKit, ARKit, Core ML, MapKit, Core Location and Core Bluetooth connected to your product, with permission prompts timed and worded so people understand the request.

03
Payments and subscriptions

Apple Pay for physical goods and StoreKit for in-app purchases and subscriptions, including receipt validation on your server and handling of renewals and refunds.

04
Offline data and sync

Local storage with SwiftData or Core Data, background refresh and conflict handling, so the app stays useful in a tunnel and reconciles cleanly afterward.

05
Widgets and extensions

Home Screen and Lock Screen widgets, Live Activities, App Intents for Siri and Shortcuts, and share extensions that put your product where people already look.

06
App Store delivery

Certificates, provisioning, privacy manifests, TestFlight groups, phased release and App Review responses handled by us, with builds produced by an automated pipeline.

04In The App

Details Users Can Feel

Native navigation

Tab bars, sheets and gestures that behave as iPhone users expect.

Lock Screen widget

Key information from your app visible without opening it.

Face ID sign-in

Biometric authentication with credentials held in the device Keychain.

Apple Pay checkout

Payment confirmed with a double click, no card form to fill.

06How It Runs

From Kickoff to Launch

01
Define and prototype
02
Design for iOS
03
Build and beta
04
Submit and release
01
Define and prototype

We agree on the core flows, the Apple frameworks involved and the minimum iOS version, then prototype the riskiest interaction on a real device to confirm it works as designed.

02
Design for iOS

Screens are designed against the Human Interface Guidelines with system components, Dynamic Type and dark mode in mind, and reviewed as a clickable prototype before engineering starts on them.

03
Build and beta

Features ship to TestFlight in regular builds your team can install. We test on a range of iPhone and iPad sizes and iOS versions, and track crashes and feedback from testers.

04
Submit and release

We prepare the listing, privacy details and review notes, submit to App Review and answer any questions. The release rolls out in phases while we watch crash and performance data.

08Who It Is For

Built for Teams Like Yours

FLAGSHIP
Your product depends on what only iOS offers

Most of your users carry an iPhone, and the experience you have in mind leans on Apple hardware or system features such as health data, augmented reality, widgets or wallet payments. You want an app that feels native and keeps pace with each new iOS release.

09Questions

What buyers ask before they start

If yours is not here, ask us directly. The first conversation is free and useful whether or not we work together.

Choose native when the app leans heavily on Apple frameworks such as HealthKit, ARKit or Core Bluetooth, when it needs widgets, Live Activities or a Watch companion, or when animation and scrolling quality are central to the product. Choose React Native when you need iOS and Android together, the screens are mostly forms, lists and content, and one team will maintain both. We build both and will say which fits.

SwiftUI is our default for new apps, because it is where Apple is investing and it produces less code for standard screens. UIKit remains the better tool for some cases, including complex collection layouts, custom text editing and certain camera or map interactions, and the two work together in one app. For an existing UIKit codebase we add SwiftUI screen by screen instead of rewriting what already works.

We reduce the risk early by checking your concept against the App Store Review Guidelines during scoping, particularly around payments, account deletion, privacy disclosures and user-generated content. Before submission we complete the privacy details, review notes and a demo account. If Apple raises an issue, we respond, make the change and resubmit. Approval is Apple's decision, so we cannot promise an outcome or a date.

We settle this during scoping using your audience data where it exists. Supporting the current iOS release and the one before it covers most active devices and keeps newer APIs available, while going further back adds testing effort and limits what SwiftUI can do. iPad support is a separate decision, since a good iPad layout is designed for the larger screen and is never a stretched phone app.

An iOS app needs attention every year, because each new iOS version and device can change behavior and Apple updates its requirements. After launch we monitor crashes and reviews, fix issues and plan the next release with you. Ongoing work can be covered by a support arrangement set out in a proposal. If your own team takes over, they receive the full source, documentation and the release pipeline.
