An app that passes App Store review the first time
Build to Apple's Human Interface Guidelines and App Store Review Guidelines from day one, so submission doesn't turn into a two-week back-and-forth with Apple.

Quick answer
What is iOS app development?
iOS app development is the process of designing, building and releasing native apps for iPhone, iPad and other Apple devices, typically using Swift and SwiftUI. Integr8e delivers iOS app development end to end—strategy, UX, native engineering, Apple ecosystem integration, App Store submission and ongoing support.
- Native Swift & SwiftUI engineering
- Built to Apple's Human Interface Guidelines
- App Store Connect submission handled
- Tested across iPhone, iPad & iOS versions
Business outcomes
Built for App Store review, not just a demo.
Integr8e approaches ios app development as a business capability—not an isolated technical task. Priorities stay connected to the users, operations and results behind the work.
Native performance users notice
Use Swift, SwiftUI and UIKit directly instead of a cross-platform wrapper, so scrolling, animation, camera and location access feel instant on real hardware.
An app that fits the Apple ecosystem
Support the iPhone and iPad sizes, iOS versions and native frameworks—Face ID, Apple Pay, push notifications, widgets—your users already expect.
Full ownership of the code and Apple accounts
Receive maintainable Swift source code, App Store Connect access and documentation for a product you control, not one locked to a single agency or contractor.
What we deliver
iOS app development services from strategy to App Store.
One connected team covers the decisions and delivery work needed to move from uncertainty to a dependable outcome.
Discovery & platform strategy
Clarify the core user journey, target devices, iOS version range and whether native—rather than cross-platform—is the right call before design starts.
UX & Apple Human Interface Guidelines
Design navigation, interaction and accessibility that follow Apple's HIG so the app feels native, not adapted from another platform.
Native Swift & SwiftUI engineering
Build the app in Swift, SwiftUI and UIKit with Combine and Core Data, connected to secure backend services and APIs.
Apple ecosystem integration
Connect Face ID and Touch ID, Apple Pay, push notifications, HealthKit, widgets and other native frameworks your product needs.
Device & App Store quality assurance
Test across iPhone and iPad models, iOS versions and network conditions, then validate against Apple's Review Guidelines before submission.
App Store release & growth
Manage App Store Connect, versioning, phased rollouts, crash monitoring and post-launch iteration using real usage data.
Is this the right fit?
Best suited for founders and product teams launching a new iPhone or iPad app, or rebuilding an existing iOS app that needs to be faster, more stable, or ready to scale.
Not every challenge needs the same team or solution. We start by testing the business case, current constraints and fastest credible route to value—then recommend a scope that fits the evidence.
Delivery architecture
A controlled path from concept to a live App Store release.
The plan adapts to your context, while short feedback loops and visible milestones keep the engagement controlled.
- 01
Discover
Define users, core journeys, target devices, iOS version range and the business case for a native build.
- 02
Design
Prototype navigation, interaction and visual design against Apple's Human Interface Guidelines before engineering starts.
- 03
Build
Develop the app in Swift and SwiftUI in short iterations, with a working build on real devices at every milestone.
- 04
Assure
Test devices, iOS versions, accessibility, performance and Apple's App Store Review Guidelines ahead of submission.
- 05
Launch & grow
Submit to the App Store, monitor crashes and adoption, and prioritise updates using production evidence.
Technology context
Tools chosen around the problem—not the trend.
We select platforms against security, scale, team fit, integration needs and the full cost of ownership.

What is iOS app development?
iOS app development is the process of designing, building and releasing native apps for iPhone, iPad and other Apple devices, typically using Swift and SwiftUI. Integr8e delivers iOS app development end to end—strategy, UX, native engineering, Apple ecosystem integration, App Store submission and ongoing support.
What iOS app development services does Integr8e provide?
Integr8e designs and builds native iPhone and iPad apps, including UX design against Apple's Human Interface Guidelines, Swift and SwiftUI engineering, backend and API integration, Apple ecosystem features such as Apple Pay and push notifications, quality assurance, and App Store submission and support.
Should I build a native iOS app or use a cross-platform framework like React Native or Flutter?
Native Swift and SwiftUI development gives the best performance, App Store compatibility and same-day access to new Apple frameworks, which matters for apps with heavy animation, camera, AR or hardware use. Cross-platform tools can lower cost when you also need Android from one codebase and performance needs are moderate. Integr8e reviews your requirements and audience before recommending either path.
How much does iOS app development cost?
Cost depends on scope—a focused MVP with a handful of core screens costs less than a full-featured app with backend integrations, Apple Pay, offline support and complex business logic. Integr8e scopes the requirement first and provides a phased estimate with clear assumptions rather than a generic day rate.
How long does it take to build an iOS app?
A focused iOS MVP typically takes eight to twelve weeks, while a fuller app with integrations, multiple user roles and Apple ecosystem features takes longer. Integr8e defines milestones after discovery instead of giving an unreliable one-size-fits-all timeline.
Will you sign an NDA, and who owns the app and code afterwards?
Yes. Integr8e signs an NDA before discovery begins if you need one. Ownership and licensing are set out in the engagement agreement, and you receive the Swift source code, App Store Connect access and documentation—no hidden dependency on our team to operate or extend the app.
Can you modernise or rebuild an existing iOS app, including migrating Objective-C to Swift?
Yes. Integr8e audits the existing codebase, architecture, crash and performance data, and App Store rating before planning an incremental rebuild or a phased Objective-C to Swift migration that avoids a risky rewrite from scratch.
How do you handle App Store submission and rejections?
Integr8e validates the app against Apple's App Store Review Guidelines before submission, prepares screenshots, privacy details and metadata, and manages the App Store Connect submission. If Apple raises a rejection, we diagnose the specific guideline and resubmit rather than guessing at a fix.
Can an iOS app integrate with our existing systems and APIs?
Yes. iOS apps can connect to CRM, ERP, payment, identity and analytics systems through REST or GraphQL APIs, webhooks, or a dedicated integration layer, with secure authentication built around your existing infrastructure.
What support is available after the iOS app launches?
Integr8e can provide crash monitoring, iOS version compatibility updates, App Store metadata and review management, performance improvement and feature development after launch, matched to how actively the app is used.
