iOS app development services from first build to long-term support

Six service lines for companies that need iOS apps their customers rely on. Each one is delivered by the team that owns it.

New iOS app development

New iOS apps in Swift and SwiftUI, from a first release to a full product with backend integration. You get TestFlight builds every sprint and the source code in your own repository.

iPhone and iPad apps

Layouts that adapt to iPhone, iPad, Split View and Stage Manager, with widgets, Apple Pay and push notifications scoped per device.

Modernization to Swift and SwiftUI

Legacy Objective-C, UIKit or hybrid code moved to Swift and SwiftUI one module at a time, so the app keeps shipping during the move.

iOS app design

Interfaces that follow the Apple Human Interface Guidelines, with Dynamic Type, Dark Mode and VoiceOver designed in before the build starts.

Cross-platform when native is the wrong call

When you need iOS and Android on one budget, we build with React Native or Kotlin Multiplatform and share logic between the two apps.

Maintenance and support

Yearly iOS and Xcode SDK updates, crash monitoring, deprecation fixes and dependency upgrades, with support terms agreed before launch.

UBS: a mobile banking app moved onto native iOS foundations

UBS wanted its personal mobile banking app to put clients first, and it was still running on a hybrid Cordova framework.

Netguru designers worked inside a UBS feature team. Payments and login were rebuilt natively and shipped, and we supported the move onto native iOS and Android.

When looking for design support, you’re looking for quality and speed that match your standards.

How iOS delivery runs from discovery to the App Store

Each phase ends with something you review and approve.

  1. Discovery

    Workshops map user roles, integrations, data flows and technical risks. You receive a scoped backlog, a technical approach and an estimate to sign off.
  2. Design

    Wireframes and a clickable Figma prototype that follows the Human Interface Guidelines. You receive the prototype and a design system to approve.
  3. Build

    Swift and SwiftUI in two-week sprints, with Xcode Cloud running builds and tests on every pull request. You receive a working build and a demo after each sprint.
  4. QA and TestFlight

    XCTest, XCUITest and a device matrix, then TestFlight beta testing with your stakeholders. You receive a release candidate and a test report.
  5. App Store submission

    Metadata, screenshots and privacy labels, checked against the App Store Review Guidelines before submission. Apple decides the review, so we plan buffer for it.
  6. Handover and support

    The app ships under your own Apple Developer Program and App Store Connect accounts. You receive the repository, CI configuration, documentation and agreed support terms.

How we build iOS apps that pass review and stay fast

The engineering standards behind every iOS app we ship.

SwiftUI and UIKit judgment

SwiftUI is our default for new screens. We pick UIKit for complex collection layouts, custom camera flows or fine gesture control, and keep Objective-C interop only for legacy modules.

Testing and CI/CD

XCTest, XCUITest and Instruments profiling cover logic, interface and performance. Xcode Cloud or Fastlane ships TestFlight builds without manual steps.

Accessibility

Dynamic Type, Dark Mode and VoiceOver support, reviewed by our IAAP-certified accessibility specialist before release.

Security: ISO 27001 and OWASP

Keychain storage, certificate pinning and Face ID authentication under Netguru's ISO 27001-certified processes, with OWASP mobile risks checked before launch.

AI features where they fit

On-device models with Core ML and Vision keep user data on the phone, and larger models run through a backend API, added only when they solve a user problem.

What our clients say

How you can work with us

Three ways to start. Each one comes with the same delivery standards and a named delivery lead.

Fixed-scope project

A defined scope, timeline and budget, agreed after a paid discovery phase. It suits a first release or a well-specified module.

Dedicated team

A cross-functional team of iOS engineers, a designer, QA and a delivery lead that owns a roadmap with you sprint by sprint, under time and materials.

Team extension

Senior iOS engineers who join your in-house team, follow your process and tools, and are matched to the skills your roadmap needs.

iOS app development services: your questions answered

What are iOS app development services?

iOS app development services cover the design, build, testing, release and upkeep of apps for iPhone and iPad, written in Swift and built in Xcode. They differ from general mobile app development, which also covers Android, and run from new builds and modernization to maintenance.

How much does it cost to develop an iOS app?

Cost depends on scope and the number of user roles, integrations with payment, CRM or health systems, design depth, compliance and security needs, and team shape. We don't quote before a discovery phase, which turns these drivers into a scoped backlog and an estimate you can compare across vendors.

Which engagement model fits an iOS project?

Fixed price suits a well-defined scope, time and materials suits a product that changes as users respond, and a dedicated team suits a long roadmap. We usually recommend a fixed-scope discovery followed by time and materials for the build. Team extension adds our iOS engineers to your in-house team.

How long does an iOS app take to build?

Timeline depends on the number of screens and user roles, backend readiness, third-party integrations and how fast designs are signed off. Discovery produces a delivery plan with milestones, and Apple's review time sits outside anyone's control, so we plan buffer for submission.

How do you choose an iOS app development company?

Check the evidence before the pitch:

  • live App Store apps and case studies in your sector;
  • a security certification such as ISO 27001;
  • code ownership, IP assignment and your own Apple Developer Program account;
  • a statement of work with scope and deliverables per phase;
  • written support terms for after launch.

Ask who will work on your app, and when you will get TestFlight builds.

Swift or Objective-C, native or cross-platform?

We default to Swift with SwiftUI for new apps and use UIKit where a screen needs finer control. We recommend native when the app relies on the camera, Bluetooth, widgets or heavy animation, and React Native or Kotlin Multiplatform when you need iOS and Android on one budget. See our mobile app development services.

How long does App Store approval take?

Apple decides review time and does not guarantee a turnaround, so we plan buffer into every launch. Common causes of rejection are missing privacy disclosures, crashes, incomplete metadata and broken sign-in flows, and our pre-submission check against the App Store Review Guidelines catches them.

SwiftUI or UIKit: which should we choose?

SwiftUI ships screens faster and needs less code, so it is our default for new apps that target recent iOS versions. UIKit still wins for complex collection layouts, custom camera flows, fine gesture control and apps that must support older iOS releases. Most long-lived apps mix both, with UIKit views wrapped for SwiftUI where it pays off.

Can I develop my own iOS app?

Yes. You need a Mac with Xcode, Swift skills and a paid Apple Developer Program membership to publish on the App Store. Companies usually bring in an iOS development company when the app handles payments, personal data or integrations, or when the business needs a release date it can plan around.

What does post-launch support cover?

Yearly iOS and Xcode SDK updates, crash monitoring, deprecation work and dependency upgrades, plus bug fixes and small improvements. SLA scope, such as severity levels and hours of cover, is agreed in the contract before launch.

Who is on an iOS project team?

A typical team has senior and mid-level iOS engineers led by a tech lead, a product designer, a QA engineer and a delivery lead, sized to the scope and growing or shrinking with the roadmap. Our guide to the iOS app development team explains the roles and skills in detail.
