iOS app development is the process of creating mobile software for Apple’s iPhone, iPad, Apple Watch, and Apple TV. iOS runs on over 1.2 billion active Apple devices globally, with the United States consistently showing iPhone market share above 55 percent. iOS apps are built in Swift, Apple’s modern type-safe language, and use SwiftUI for declarative UI design. The distribution platform is the Apple App Store, which hosts over 1.8 million apps reviewed against Apple’s strict Human Interface Guidelines (HIG). Native iOS apps can access powerful hardware and platform features unavailable to web or cross-platform apps, including Face ID biometrics, HealthKit health data, ARKit augmented reality, Core ML on-device machine learning, Apple Pay payments, WidgetKit home screen widgets, and Live Activities on the Dynamic Island.
At Maze Digital, our iOS development service is end-to-end: product strategy, UX wireframes following Apple HIG, Figma UI design with SF Symbols and Dark Mode, Swift and SwiftUI engineering in Agile sprints, QA on real iPhones and iPads, and full App Store submission with ASO optimization.
Our iOS Services
We cover the complete iOS development spectrum. One team handles strategy, design, engineering, and launch.
We build high-performance native iPhone apps using Swift and SwiftUI. Every app follows Apple's Human Interface Guidelines precisely, uses the latest iOS APIs, and delivers the fluid, premium experience that iPhone users expect. We ship clean, well-documented Swift code that any iOS developer can read, maintain, and build on for years.
We build universal iOS apps that scale beautifully from iPhone SE to iPad Pro 13-inch. Using SwiftUI's adaptive layouts, split-view containers, sidebar navigation, and Apple Pencil support, your app becomes a genuinely powerful productivity tool on iPad without feeling like a stretched phone app.
We extend iOS apps to Apple Watch with WatchKit and SwiftUI for watchOS. Complications, health metric tracking, workout sessions, and quick-glance notifications designed for the wrist.
Secure field service tools, mobile CRMs, inspection apps, and B2B platforms. MDM compatible, SSO integration, enterprise-grade security built from the first sprint.
HIPAA-compliant iPhone apps for clinics, hospitals, and health startups. AES-256 encryption, Face ID, HealthKit, and BAA included.
Your iOS app deserves to look and perform like it was built this year. We migrate legacy iOS apps from Objective-C to Swift, UIKit to SwiftUI, and outdated UI patterns to modern equivalents for iOS. We fix App Store Review rejections, improve performance using Instruments, and add new Apple platform features without breaking existing functionality.

The Apple platform extends far beyond iPhone. We build apps that feel native on every Apple device your users own.
Universal apps with adaptive SwiftUI layouts, split-view navigation, Stage Manager support, and Apple Pencil integration across every iOS device from iPhone SE to iPad Pro 13-inch.
Platform Integrations
Native iOS apps can do things no cross-platform app can match. These Apple framework integrations give your product a genuine competitive advantage over apps built with React Native or Flutter.
We run a structured discovery sprint to define your target users, core features, your industry competition, and tech stack. You receive a detailed PRD and project roadmap before a single wireframe is drawn.
Our design team creates user flows, wireframes, and full Figma UI designs with interactive prototypes. We design specifically for mobile, thumb zones, gestures, platform conventions, and accessibility.
We craft pixel-perfect UI designs in Figma across all breakpoints. Interactive prototypes let you review and approve the experience before a single line of code is written.
Stripe payments, Twilio SMS/voice, push notifications (Firebase FCM / APNs), Google Maps, social logins, analytics SDKs, wearables, and any other API your app needs, fully integrated and tested.
We test on real iOS and Android devices across OS versions, screen sizes, and network conditions. We integrate Firebase Crashlytics, Sentry, and automated test suites before every release.
We handle the full submission process metadata, screenshots, compliance review, category optimization, and App Store Optimization (ASO) basics, so your app gets approved and discovered.
We have shipped over 50 iOS apps to the App Store. Here is what separates our work from the agencies that will give you a cheaper quote.

A structured 6-step process with full transparency at every stage. You always know what is being built, what is next, and when you will see it on your iPhone.
2-3 Days
We open every engagement with a structured discovery sprint. We define your target iPhone users, the minimum iOS version to support, which device classes to cover (iPhone only, iPad universal, Apple Watch), the core feature set, and the right backend architecture. The output is a full Product Requirements Document with a clear tech stack recommendation including Swift version, Jetpack equivalents, architecture pattern (MVVM or TCA), API contract design, and a timeline with milestones. Both teams are fully aligned before a single wireframe is drawn.
3 to 5 Days
Our UX team maps every user journey and produces low-fidelity wireframes following Apple's Human Interface Guidelines. We design for iOS-specific patterns: tab bar navigation, navigation stacks, sheets and modals, gesture navigation for iOS 16 and later, pull-to-refresh, swipe actions, and contextual menus. We wireframe for iPhone and iPad from the start rather than retrofitting adaptive layouts afterward. Every wireframe screen is reviewed and signed off by you before visual design begins.
7 to 14 Days
We design your complete iOS app UI in Figma. Every screen, every state (empty, loading, error, success, and partial data), every transition, and every platform-specific detail. We use SF Symbols for all iconography, Dynamic Type across all text sizes from Extra Small to Accessibility Extra Extra Extra Large, semantic system colors so Dark Mode works automatically, and the iOS 8-point spatial grid for precise spacing. We build an interactive Figma prototype with real iOS transitions for your approval before Swift development begins.
4 to 16 Weeks
Engineers build your iOS app in 2-week Agile sprints. The stack is Swift with SwiftUI, MVVM architecture with Combine for reactive state, URLSession and Codable for networking, SwiftData or Core Data for local persistence, Keychain for secure credential storage, and the specific Apple frameworks your features require. After every sprint, a new TestFlight build is deployed to your iPhone. You test real functionality on your actual device, report feedback, and we adjust the next sprint backlog based on what you find. No surprises at launch because you have been testing the app for weeks already.
5 to 7 Days
We test on real Apple hardware across the current device lineup: iPhone SE 3rd gen, iPhone 15 standard, iPhone 15 Pro, iPhone 15 Pro Max, iPad Air, and iPad Pro. We cover iOS 16, 17, and 18. We run unit tests with XCTest, UI automation with XCUITest, memory leak detection with Instruments, and performance profiling. We verify Dynamic Type at all accessibility sizes, VoiceOver screen reader compatibility, Dark Mode rendering, and every App Store Review Guideline checklist item before submission. We also test App Tracking Transparency flows, App Privacy nutrition labels accuracy, and data safety section declarations.
2 to 3 Days, Then Ongoing
We handle the complete App Store submission. App signing with a distribution certificate, optimized App Store Connect listing with keyword research for ASO, screenshots and App Preview videos for all required device sizes, App Privacy labels, Data Safety disclosure, Content Rating questionnaire, and an initial phased release starting at 10 percent of users to catch any issues before full rollout. Firebase Crashlytics is live before launch day. We review the first 48 hours of crash reports personally. Every project includes a 30-day post-launch warranty covering critical bug fixes at no additional charge.
