What is iOS app development?
iOS app development is building applications for iPhone and iPad, in Swift and SwiftUI natively or cross-platform, and publishing them through Apple's App Store. iOS users notice when an app ignores platform conventions. We build to Apple's Human Interface Guidelines and prepare for App Store review as part of the plan, not after a rejection.
iOS users notice when an app does not follow platform conventions. Navigation that behaves subtly wrong, type that ignores Dynamic Type, gestures that fight the system — none of it is fatal individually, and together it makes an app feel foreign.
We build to Apple's Human Interface Guidelines rather than porting an Android layout across, and we prepare for App Store review as part of the plan. Review rejections are common, usually predictable, and much cheaper to avoid than to appeal.
What this includes
- 01
Swift and SwiftUI
Native iOS built with current Apple frameworks where platform depth matters.
- 02
Cross-platform iOS
React Native or Flutter when iOS and Android should share a codebase.
- 03
iPad and adaptive layouts
Interfaces that work across iPhone and iPad sizes rather than stretching.
- 04
App Store preparation
Listing, privacy declarations, and guideline compliance handled before submission.
- 05
Apple platform integration
Sign in with Apple, biometrics, push notifications, and in-app purchase where relevant.
- 06
Accessibility
VoiceOver and Dynamic Type support, which Apple reviews and users depend on.
Situations we see most often
Reaching a premium or international audience
In several markets and segments, iOS carries disproportionate spending and engagement.
Bringing an existing Android app to iOS
Extending to a second platform, either natively or by moving to a shared cross-platform codebase.
Apps that depend on Apple capabilities
Products relying on biometrics, in-app purchase, or deep hardware integration.
Enterprise iOS distribution
Internal apps distributed to staff devices rather than through the public store.
What to know before you start
Native Swift or cross-platform for iOS?
Native Swift and SwiftUI give the closest fit to Apple's platform and immediate access to new iOS features. Cross-platform with React Native or Flutter serves iOS and Android from one codebase, which is the right call for most business applications.
Native iOS earns its extra cost when the app depends on Apple-specific capability early, such as new frameworks, widgets or deep hardware integration, or when performance needs exceed what cross-platform comfortably delivers.
What does App Store review check, and why are apps rejected?
Apple reviews every release against its guidelines. Common reasons for rejection are predictable: missing or inaccurate privacy declarations, no in-app account deletion for apps with sign-up, incomplete metadata or screenshots, login required without a demo account for the reviewer, and payments for digital goods outside Apple's in-app purchase.
Review itself usually takes a day or two. We plan for these requirements from the start and test through TestFlight, so the first submission is prepared rather than discovering them in a rejection.
What does building to Apple's conventions mean in practice?
iOS users notice when an app behaves like a ported Android app. Navigation should use the platform's patterns, back gestures should work everywhere, type should respect Dynamic Type so people who enlarge text can still use the app, and controls should look and respond the way the rest of the system does.
We design and build to Apple's Human Interface Guidelines, support VoiceOver and Dark Mode, and test on a range of iPhone and iPad sizes, so the app feels at home rather than translated.
How is an iOS app tested before release?
On a range of real iPhone and iPad sizes and the iOS versions your users run, plus automated tests for the core flows. Builds go to TestFlight, where your team and selected users can try each release before it reaches the App Store.
Crash reporting and analytics are in place from the first build, so issues that only appear on particular devices or OS versions are visible quickly rather than through store reviews.
How do push notifications work on iOS?
Through Apple's Push Notification service. The app asks permission at a moment when the value is obvious, rather than on first launch, and your backend sends notifications through APNs when something relevant happens.
Notification categories and quiet delivery let users control what they receive, which keeps them from switching notifications off entirely.
What drives the cost of an iOS app?
iOS cost depends on what the app does and how closely it uses Apple's platform. These factors move it most.
| Factor | Effect | Why it matters |
|---|---|---|
| Backend and integrations | High | The API, admin panel and connections to your systems are often more work than the app itself. |
| Native or cross-platform | High | Native Swift serves iOS only; cross-platform covers Android too from one codebase. |
| Apple platform features | Medium | Sign in with Apple, push notifications, StoreKit and HealthKit-style integrations each add work and review requirements. |
| iPad and adaptive layouts | Medium | Supporting iPad properly, with layouts that use the larger screen, is extra design and testing. |
| Accessibility | Medium | Dynamic Type, VoiceOver and contrast support are expected by iOS users and need deliberate work. |
| App Store preparation | Low | Privacy declarations, account deletion and metadata are predictable work when planned rather than discovered. |

Questions we get asked
01Do you have apps published on the App Store?
Our published mobile work to date is on Google Play, and our first App Store releases are in progress. We build iOS with the same stack and conventions either way — we would rather tell you exactly where we stand than imply a longer store history than we have.
02How long does App Store review take?
Usually a day or two, though rejections add cycles. Most rejections come from predictable causes — privacy declarations, account deletion requirements, incomplete metadata — so we address those before submitting rather than discovering them in review.
03Can one codebase serve both iOS and Android?
Yes, with React Native or Flutter, and for most business applications that is the right call. Native iOS earns its extra cost when you need platform capability early or performance at a level cross-platform cannot reach.
04Do you publish under our Apple developer account?
Yes, and we recommend it, so the listing, reviews and customer relationship belong to you. We work within your account and handle TestFlight, submission and release.
05Can you bring our Android app to iOS?
Yes. If the Android app is native, we assess whether a native iOS build or a move to a shared cross-platform codebase makes more sense long term, and recommend one before starting.
