Frequently Asked Questions
What services do iPhone app development companies offer?
Core services: native iOS development (Swift, SwiftUI), cross-platform development (Flutter for iOS + Android simultaneously), UI/UX design for iOS (following Apple Human Interface Guidelines), App Store submission and optimization (ASO), backend and API development, app maintenance and updates, iOS app testing and QA, Apple Watch and iPad app development, app migration and modernization, and push notification and analytics integration. Specialized: AR/VR apps using ARKit, HealthKit integration for health apps, Apple Pay and in-app purchase integration, and Core ML for on-device AI features.
How much does iPhone app development cost?
Cost ranges: simple app (informational, basic features): $15,000-40,000. Medium complexity (social features, API integrations): $40,000-100,000. Complex app (marketplace, fintech, AI features): $100,000-300,000. Enterprise (multi-platform, complex backend): $300,000-1,000,000+. Cross-platform with Flutter: 30-40% less than native. Factors: feature complexity, design requirements, third-party integrations, backend infrastructure, and ongoing maintenance (15-20% of development cost annually). Apple developer account: $99/year required for App Store publishing.
Should I build native iOS or cross-platform?
Native iOS (Swift/SwiftUI) advantages: best performance and animations, full access to latest iOS features (first day), seamless Apple ecosystem integration (Watch, iPad, Mac), best user experience following Apple guidelines, and better for performance-intensive apps (gaming, AR, video). Cross-platform (Flutter) advantages: one codebase for iOS + Android (30-40% savings), faster development, easier maintenance, near-native performance for 90%+ of apps. Recommendation: Flutter for most business apps. Native Swift for: gaming, AR/VR, apps requiring deep Apple ecosystem integration, or when iOS is the only target platform.
How long does it take to develop an iPhone app?
Development timeline: simple app: 2-3 months. Medium complexity: 3-6 months. Complex app: 6-12 months. Enterprise: 12-18+ months. Phases: discovery and planning (2-4 weeks), UI/UX design (3-6 weeks), development (8-32 weeks depending on complexity), testing and QA (2-4 weeks), App Store submission and review (1-2 weeks). Apple App Store review: typically 24-48 hours, but can take up to 7 days. Factor in 1-2 revision cycles if Apple requests changes. Total from concept to launch: add 20% buffer to estimates.
How do I get my app approved on the App Store?
App Store approval checklist: follow Apple Human Interface Guidelines, provide accurate app description and screenshots, include privacy policy (mandatory), implement App Tracking Transparency if collecting data, ensure no crashes or major bugs, no placeholder or test content, complete metadata (description, keywords, category), proper content rating, working sign-in credentials for review team, and comply with in-app purchase rules (30% Apple commission). Common rejection reasons: bugs and crashes (34%), design issues (12%), insufficient information (10%), and privacy violations (8%). Tip: use TestFlight for thorough beta testing before submission.
