iOS App Development Services

Polished apps for iPhone, built to Apple's standards.

iOS app development services cover designing, building and releasing apps for iPhone, and often iPad, through the App Store. NetOfficials builds native iOS apps in Swift, from a written scope you approve to a build that is ready for Apple's review. The native language used for iOS is covered by our Swift app development services.

What We Build

What Is Included in Our iOS App Development Services

The parts of an iOS project that decide how the app feels and whether Apple approves it.

  • Native iPhone Build

    An app written in Swift that follows Apple's Human Interface Guidelines.

  • Interface for Apple Devices

    Layouts that adapt to iPhone sizes, Dynamic Type, dark mode and, where needed, iPad.

  • Privacy and Permissions

    Clear permission prompts, Face ID and Touch ID sign-in, and secure storage in the Keychain.

  • Apple Pay and In-App Purchases

    Payments and subscriptions built to Apple's rules for digital goods.

  • Testing with TestFlight

    Builds shared with your testers early, so feedback arrives before review.

  • App Store Submission

    Metadata, screenshots, privacy details and the review process handled with you.

Technology Choice

SwiftUI or UIKit for Your iOS App?

Apple supports two ways to build the interface. The right one depends on how new your app is and which iOS versions you must support. We recommend one in discovery.

SwiftUI is usually the better choice when

  • You are starting a new app
  • You can set a recent minimum iOS version
  • You want to reuse screens on iPad and Mac
  • You want faster interface changes

  3. Build

    Features built in Swift in sprints, with a demo build to react to each time.

    Installable build
  4. TestFlight Beta

    Your testers use the app on real iPhones and send feedback through TestFlight.

Cost

What Affects the Cost of iOS App Development

We do not quote from a price list, because two iOS apps rarely share a scope. Cost follows a handful of decisions, which we settle with you in discovery.

  • Design depth

    Custom animation and a highly branded interface take more design and build effort than standard components.

  • Device range

    Adding iPad, Apple Watch or widgets expands layouts and testing.

  • Purchases and subscriptions

    In-app purchases follow Apple's rules, which affects design, build and testing.

  • Privacy requirements

    Sensitive data, Face ID and tracking consent add decisions and App Store disclosures.

  • Apple services

    Push notifications, Sign in with Apple, HealthKit or CloudKit each add integration work.

  • Review readiness

    Apps with accounts, payments or user content need extra preparation for Apple's review.

FAQ

iOS App Development FAQs

What is iOS app development?

It is designing, building and releasing apps for iPhone and other Apple devices. Native iOS apps are written in Swift and are distributed through the App Store.

Do I need a Mac and an Apple developer account?

You do not need a Mac yourself. You do need an Apple Developer account in your own name to publish, and we help you set it up.

Will Apple approve my app?

We cannot promise approval, because Apple makes that decision. We build to its guidelines and prepare the submission carefully to reduce the chance of rejection.

Can the iPhone app also run on iPad?

It can. We agree in discovery whether iPad gets its own layouts or simply runs the iPhone app, since that changes the design and testing work.

Who owns the code and IP?

You do. The contract settles IP assignment before the build starts, and the iOS source code and documentation are handed over in full.

Can you update an app that is already on the App Store?

Yes. We review the code and release history first, then agree the changes in a written scope you approve before work starts.
