iOS App Development

iOS App Development in Baku, Azerbaijan – Native iPhone & iPad Apps | ONE Studio

iOS users represent the highest-value mobile audience: higher purchasing power, better engagement, more willingness to pay for apps and in-app purchases. ONE Studio develops iOS apps for clients across Azerbaijan and internationally — native Swift apps, SwiftUI interfaces, deep iOS integrations, optimised for performance and App Store success.

iOS development services we offer

• Native iOS apps — Swift and SwiftUI apps for iPhone, iPad and Apple Watch.
• iOS app modernisation — migrating older Objective-C apps or hybrid apps to modern Swift/SwiftUI.
• Apple Watch and iPadOS apps — leveraging Apple's ecosystem of devices.
• SDK integrations — Apple Pay, Sign in with Apple, ARKit, CoreML, HealthKit, MapKit, MusicKit, CarPlay.
• App Store submission and approval — preparing for Apple's strict review process; maximising approval likelihood first time.
• iOS performance optimisation — startup time, frame rate, battery, memory.
• iOS security — keychain, biometric authentication, secure data storage, App Transport Security.
• Push notifications and rich content — APNs, notification extensions, content extensions.
• Subscriptions and in-app purchases — StoreKit, subscription management, server validation.
• Offline-first architectures — Core Data, sync, conflict resolution.
• Universal apps — single codebase for iPhone, iPad, and Mac (Catalyst).

Native iOS or cross-platform?

Both have merits depending on the project:

• Native iOS (Swift / SwiftUI) — best performance, full platform features, fastest access to new iOS APIs, easiest to maintain long-term, best chance of App Store Featured.
• React Native — faster development for cross-platform; ~80–90% of native performance for most apps; limited access to specific iOS-only features without native code.
• Flutter — Google's cross-platform framework; near-native performance; growing ecosystem; less seamless on iOS than Android.
• Hybrid (Cordova, Ionic) — generally not recommended for new iOS apps; legacy apps may need migration.

For most consumer-facing iOS apps where quality matters, native is the right choice. For internal tools, B2B apps, and apps that must launch on both platforms with limited budget, React Native or Flutter is pragmatic.

Our iOS development process

1. Discovery and product strategy. What problem does the app solve? Who uses it? Apple's Human Interface Guidelines compliance from day one.
2. iOS-specific UI/UX design. Wireframes, prototypes, high-fidelity designs in Figma. Following Apple HIG: navigation patterns, typography, spacing, gestures.
3. Architecture. Swift / SwiftUI, MVVM or composable architecture, dependency injection, modularisation for maintainability.
4. Backend. If needed, custom backend (Laravel, Node, Python) or backend-as-a-service (Firebase, Supabase). API design, real-time features, push notifications.
5. Implementation. 2-week sprints, code reviews, automated testing where appropriate.
6. QA testing. Real iPhone and iPad devices, multiple iOS versions, edge cases, performance.
7. App Store submission. Screenshots, descriptions, keywords, age rating, App Tracking Transparency compliance, privacy nutrition labels. We handle Apple's review process.
8. Launch and iteration. Crash monitoring (Crashlytics), analytics, user feedback, regular updates.

Common questions about iOS development

How long does iOS app development take? Simple: 3–4 months. Mid-complexity: 5–8 months. Complex: 9–18 months.

Can the iOS app share code with Android? Yes if built with React Native, Flutter or Kotlin Multiplatform. Native Swift cannot directly share with Android.

Apple's 30% commission — can it be avoided? Apple charges 30% (15% for some categories) on in-app purchases. Physical goods sold through app pay 0% to Apple. We help structure monetisation appropriately.

What about App Tracking Transparency? iOS 14+ requires explicit user permission for tracking. We implement properly and follow privacy best practices.

How long does Apple's review take? Typically 1–3 days. Updates often faster. Rejections are usually clearly explained and fixable.

Should I support older iOS versions? Standard: iOS 15+ (covers ~95%+ of devices). Older support possible but adds development time and limits available features.
