iOS App Development
Native iOS in Swift and SwiftUI, scoped and shipped. We handle architecture, development, and App Store submission as a single engagement, not three separate handoffs.
If you're on this page, you already know you want iOS. The question is whether the team you hire understands the platform well enough to make the right calls before writing a single line of code, and to talk you out of native when native isn't the right answer.
when native iOS is the right call#
Native development costs more and takes longer than cross-platform alternatives. For many products, that premium is worth it. For others, it isn't. Here's how we think about it.
deep device API access: camera, ARKit, HealthKit, CoreML#
When your app depends on first-class access to Apple's hardware, live camera processing, AR, on-device ML, or health sensor data, native is not optional. Cross-platform frameworks either don't expose these APIs or route through bridge code that introduces latency you'll notice and maintenance overhead you'll regret.
performance-sensitive apps: live graphics, on-device AI inference#
Apps running live graphics or on-device inference need direct access to Metal and the Neural Engine. Native Swift gives you the full performance envelope. For most informational apps, cross-platform overhead is invisible. For performance-critical products, it isn't.
App Store compliance and review edge cases#
App Store review has gotten stricter. Apps with complex purchase flows, subscriptions, or content moderation requirements face rejections that need rapid, precise fixes. Native development gives you direct control over every component the review process examines. No third-party runtime versions failing review on someone else's release cycle.
when cross-platform genuinely covers your requirements#
If your app is content-driven or form-heavy and you need Android parity on a constrained budget, cross-platform is a legitimate choice. We'll tell you when that's the right call. See our cross-platform development service.
what we build in Swift and SwiftUI#
consumer and B2C iOS apps#
Marketplace apps, fitness products, on-demand services. Apple App Store consumer spending reached $117.6 billion in 2025, up 13.6% year-over-year and the highest on record (Business of Apps, 2026).
enterprise and internal tools for iPhone and iPad#
Field service apps, inspection tools, logistics dashboards, iPad CRMs. These usually need offline-first architecture, Bluetooth or NFC integration, and MDM compatibility. Enterprise clients routinely underestimate App Store compliance complexity for internal distribution. We handle it, including Apple Business Manager setup when direct App Store distribution isn't appropriate.
AI-integrated mobile experiences with on-device inference#
Apple's CoreML and the Neural Engine on A17 Pro and M-series chips run inference locally, no API call, no latency, no data leaving the device. We build apps that use on-device models for live image classification, natural language processing, and anomaly detection. Our work in agentic AI systems shapes how we design mobile AI features that do something real rather than just appearing in the feature list.
SaaS companion apps and mobile-first products#
If you're running a SaaS product and need an iOS companion, the hard part isn't the UI. It's authentication state across sessions, background sync behavior, and API design that works for mobile consumption patterns. We've done the integration work enough times to know where it gets messy.
our iOS tech stack#
Swift: language and architecture#
We write idiomatic Swift using async/await throughout. Architecture choices depend on the product: MVVM with Combine for reactive data flows, TCA for complex state management, Clean Architecture for enterprise apps. SwiftUI adoption has grown to approximately 70% of new iOS apps in 2025, up from around 40% in 2023, while UIKit still powers roughly 80% of enterprise and legacy apps (rentamac.io iOS Development Statistics, 2025).
SwiftUI: modern declarative UI#
SwiftUI is our default for new projects. Declarative layout, live previews in Xcode, and tight integration with Apple's design language make it faster to build and easier to maintain. We write custom components where Apple's defaults don't meet spec and handle iOS version compatibility explicitly rather than hoping it works.
UIKit: legacy support and advanced layout#
UIKit is still necessary for apps targeting iOS 14 or earlier, for layout requirements SwiftUI doesn't handle cleanly, and for SDKs that only expose UIKit interfaces. We know both frameworks and manage SwiftUI/UIKit interop in mixed codebases without the usual mess.
Xcode, TestFlight, and App Store Connect#
Instruments for profiling, XCTest for unit and UI tests, TestFlight for QA and beta distribution throughout the project. App Store Connect management, including provisioning profiles, metadata, and screenshot sets for every required device size, is part of every engagement. It's not a separate line item.
how we scope and deliver iOS projects#
step 1: requirements, architecture, and platform decision#
Before design or development begins, we map your requirements against platform capabilities. The output is a written architecture brief: what we'll build, what we won't, and why. We don't produce a timeline or quote before that brief exists. Skipping this step is the most common reason iOS projects go over budget.
step 2: UI/UX design and prototyping#
High-fidelity Figma prototypes before a single line of code is written. Every screen, every state, every edge case is designed first. Our UX/UI design team works in Apple's HIG and hands off in a format that maps directly to SwiftUI components, so the gap between design and implementation is as small as it can be.
step 3: development sprints and TestFlight QA#
Two-week sprints with a working TestFlight build at the end of each. You test on real hardware throughout the project. Bugs get caught in the sprint they're introduced, not at launch when the cost to fix them is higher.
step 4: App Store submission and launch#
We prepare app metadata, privacy nutrition labels, screenshot sets, and App Privacy disclosures. We submit, manage the review process, and respond to reviewer questions directly. This is part of the engagement.
step 5: post-launch support and iteration#
Most iOS products need a second sprint cycle 60-90 days after launch: tuning under real load, incorporating user feedback, fixing iOS version compatibility issues that only surface in production. We offer post-launch retainers and are available for discrete scope additions.
pricing and timelines#
MVP and simple apps ($40K-$80K, 10-16 weeks)#
Single-purpose apps: one or two core user flows, a backend integration, authentication, push notifications, and App Store submission. Typically early-stage products, internal tools, or companion apps for existing platforms.
mid-complexity products ($80K-$150K, 16-24 weeks)#
Multiple user roles, complex custom UI, deeper device API integration, offline-first architecture, or significant backend work. Enterprise field tools, consumer apps with social features, and AI-integrated products land here. For context: native iOS at this complexity level typically runs $50,000-$150,000; cross-platform alternatives cost 20-30% less but require native code for anything involving advanced device APIs (TekRevol, 2025).
complex platforms and integrations ($150K+, 5+ months)#
Multi-sided platforms, significant on-device ML, or iOS apps built as part of a larger system alongside web, API, or agentic AI backend work. Pricing reflects engineering hours.
To get an accurate scope, the fastest path is the audit and scoping engagement: a structured session that produces a written brief you can take to any development team.
FAQ#
How much does native iOS app development cost in 2026?
An MVP runs $40,000-$80,000. Mid-complexity products run $80,000-$150,000. Complex platforms with on-device ML or multi-system integration start at $150,000. These ranges cover a single iOS app. Projects that include Android, web, or backend work are scoped separately.
When should I choose native iOS over React Native or Flutter?
Choose native when your product depends on deep device API access (ARKit, CoreML, HealthKit, Metal), when performance is a core requirement, or when App Store compliance complexity requires precise control over every component. Choose cross-platform when you need Android parity on a limited budget and no device-native feature is central to the experience. See the cross-platform development page for the full breakdown.
What is the difference between Swift and SwiftUI?
Swift is the programming language. SwiftUI is a UI framework written in Swift. SwiftUI is declarative: you describe what the UI should look like in a given state and the framework handles the rest. UIKit is imperative: you manage view lifecycle and layout manually. SwiftUI is the default for new projects; UIKit is still necessary for legacy codebases and some advanced layout work.
How long does it take to develop an iOS app?
An MVP takes 10-16 weeks from scoping to App Store submission. Mid-complexity products take 16-24 weeks. The most common reason projects run long is undefined scope at the start. If requirements aren't locked before development begins, they expand during development.
What tools and integrations does an iOS development agency use?
Development: Swift, SwiftUI, UIKit, Xcode, Instruments, XCTest. Design: Figma with iOS component libraries. QA and distribution: TestFlight, App Store Connect. Backend integration: REST and GraphQL APIs, Firebase, AWS Amplify, custom backend services. CI/CD: Xcode Cloud or Fastlane depending on existing infrastructure.
Do you also build Android versions of iOS apps?
Yes. If you need both platforms, we scope them together. See the Android development service. If cross-platform is a fit for your requirements, we'll say so upfront.
