iOS users spend more, engage longer, and convert at higher rates than any other mobile platform. Unicrats builds native iOS apps in Swift and SwiftUI — not React Native or Flutter shims — delivering the fluid 120Hz animations, instant biometric authentication, and seamless iCloud sync that Apple users expect. Every app we ship meets Apple's strict Human Interface Guidelines and passes App Store review first time, every time.

Why It Matters

Key benefits for your business

⚡

Swift Performance

Swift is compiled to native machine code with zero overhead. Apps launch faster, consume less battery, and handle complex computations that would stutter on interpreted runtimes.

🎨

SwiftUI Declarative UI

Modern SwiftUI development with live previews, adaptive layouts, and built-in dark mode, Dynamic Type, and accessibility support baked in from day one.

🔗

Apple Ecosystem Integration

Native iCloud sync, Apple Pay, Face ID/Touch ID, Sign in with Apple, HealthKit, HomeKit, and ARKit — all integrated natively without third-party libraries.

💎

Premium User Demographic

iOS users have 2× the purchasing power of Android users globally. A polished iOS app positions your brand in front of the highest-value mobile audience.

🏪

App Store Trust & Distribution

The App Store's curation model means users trust apps more. We help you leverage App Store Connect, subscriptions, in-app purchases, and TestFlight beta testing.

🧠

CoreML & ARKit Access

Integrate on-device machine learning with CoreML, build immersive AR experiences with ARKit, and use Vision framework for real-time image analysis — no external AI services needed.

Our Process

How we deliver results

01

Discovery & Architecture

We define the target iOS version (typically iOS 16+), device matrix (iPhone only vs Universal), and architecture pattern. Data flow, offline sync strategy, and API contracts are agreed before design.

02

UI/UX Design (HIG-Aligned)

Figma screens aligned to Apple's Human Interface Guidelines — navigation patterns, typography, spacing, and interaction models that feel native on iOS, not ported from Android.

03

Swift Development

Development in Xcode with Swift, SwiftUI/UIKit, Combine, and async/await. Unit tests with XCTest, UI tests with XCUITest, and continuous integration via Fastlane + GitHub Actions.

04

TestFlight Beta & App Store Launch

Beta distribution via TestFlight, App Store Connect submission with complete metadata, privacy nutrition labels, and App Store screenshots. We handle the entire review process.

FAQ

Frequently asked questions

Should I use Swift or Objective-C for my iOS app?
Swift for all new projects, without exception. Objective-C is legacy — Apple's own frameworks are being rewritten in Swift, and SwiftUI is Swift-only. The only case for Objective-C is maintaining an existing Objective-C codebase, which we can also gradually migrate to Swift.
How long does App Store review take?
Apple's review typically takes 24–48 hours for standard submissions. Apps with in-app purchases, subscriptions, or sensitive categories (health, finance, kids) may take 5–7 days. Expedited review is available for critical bug fixes. Our first-submission acceptance record means you never lose time to back-and-forth with reviewers.
Should I build iOS first or Android first?
iOS first if your primary market is USA, Canada, UK, Australia, Japan, or Western Europe — these markets have higher iOS adoption and higher user spending. Android first for India, Southeast Asia, Latin America, and Africa. If budget allows, we can develop both simultaneously with a shared backend API.
How much does an iOS app cost to develop?
A straightforward informational or utility app starts around $15,000–$25,000 USD. A marketplace or social app with backend runs $40,000–$80,000. An enterprise app with complex workflows and integrations typically ranges $80,000–$200,000+. We provide a detailed SOW and fixed-price quote after the discovery phase.
SwiftUI vs UIKit — which should I choose?
SwiftUI for all new apps targeting iOS 16+. It's faster to develop, easier to maintain, and where Apple is investing. UIKit is still used for complex custom UI components, performance-critical rendering (like games), or when supporting iOS 14/15. Most of our apps use SwiftUI with UIKit bridges for specific components.
What are the most common App Store rejection reasons?
The top rejection reasons are: missing privacy policy, inaccurate app description (app does more/less than described), broken links or placeholder content, requesting unnecessary permissions, guideline 4.3 (duplicate app), and in-app purchase implementations that bypass Apple's payment system. We screen for all of these in our pre-submission review.
