iOS App Development Agencies: Swift & SwiftUI Experts

TL;DR

50 iOS development agencies compared. Average hourly rates: $110-166. Typical minimum project: $40K. Best for: native performance, Apple ecosystem integration, App Store optimization. Key skills to look for: Swift, SwiftUI, Core Data, CloudKit.

Why Choose Native iOS Development

Native iOS development using Swift and SwiftUI delivers performance that cross-platform frameworks can't match. Apps built specifically for Apple hardware achieve 60fps animations consistently, use 20-40% less battery than React Native equivalents, and launch 200-500ms faster. For apps where user experience directly impacts revenue, such as fintech, gaming, or health tracking, these differences translate to measurable business outcomes.

Apple's ecosystem offers technical advantages that require native development to access fully. Features like Siri Shortcuts, iCloud Keychain integration, Apple Watch connectivity, and handoff between devices only work reliably through native APIs. SwiftUI's declarative syntax now enables developers to build interfaces 30-50% faster than UIKit while maintaining full access to iOS capabilities. Agencies specializing in iOS development understand these APIs deeply and can implement features that cross-platform developers often skip due to complexity.

The App Store remains the highest-revenue mobile marketplace, generating $85 billion for developers in 2023. iOS users spend 2.3x more on in-app purchases than Android users. Apple's strict review process, while requiring more preparation, results in higher-quality app discovery. iOS agencies experienced in App Store Optimization (ASO) can significantly impact your app's visibility through proper keyword targeting, screenshot optimization, and review management strategies.

iOS Development Cost Breakdown

Typical Cost Ranges by App Type

Simple utility app (calculator, timer) $25,000 - $50,000
Content/media app (news, podcast) $50,000 - $100,000
E-commerce app with payments $75,000 - $150,000
Social networking features $100,000 - $250,000
Enterprise with offline sync $200,000 - $500,000+

iOS-specific costs include the $99/year Apple Developer Program fee, macOS hardware for development ($2,000-5,000 if agency doesn't have it), and App Store commission (15-30% of revenue). Design costs run higher for iOS due to Apple's Human Interface Guidelines requirements and the need for multiple device sizes including iPhone SE through Pro Max and iPad variants.

Factor in $10,000-25,000 annually for iOS version compatibility updates. Apple releases new iOS versions yearly, and maintaining support for iOS N-2 (current minus two versions) is standard practice. Agencies charging $150+/hour typically include proactive compatibility planning in their estimates, while lower-cost agencies may quote these updates separately.

When to Choose iOS Over Android or Cross-Platform

Choose iOS First When:

  • Your target users are primarily in US, Canada, UK, or Japan where iOS market share exceeds 50%
  • Revenue model depends on in-app purchases or subscriptions
  • App requires Apple Watch, AirPods, or HomePod integration
  • Performance-critical features like AR, video processing, or gaming
  • Brand perception matters and you want the "premium" association

Consider Alternatives When:

  • Budget under $25,000 total (consider React Native or Flutter)
  • You need both iOS and Android with identical launch dates
  • Target market is primarily in Asia, Africa, or South America
  • App functionality is primarily web-based content display
  • Rapid iteration with A/B testing is more important than polish

Starting with iOS and expanding to Android later is a common strategy. This approach lets you validate product-market fit with the higher-spending iOS audience before investing in cross-platform support. However, building Android after iOS typically costs 60-70% of the original iOS investment (not 50% as some claim) because architectural decisions often need revisiting. If you know you'll need both platforms within 12 months, cross-platform frameworks like React Native or Flutter may offer better total cost despite the performance tradeoffs.

iOS App Development FAQs

What's the average cost to develop an iOS app in 2025?

Simple iOS apps cost $25,000-50,000. Medium-complexity apps with user accounts, APIs, and basic features run $50,000-150,000. Complex apps with real-time features, AI, or extensive backend infrastructure range from $150,000-500,000+. These figures include design, development, and initial testing but exclude ongoing maintenance.

Should I hire a Swift or SwiftUI specialist?

SwiftUI is Apple's modern UI framework released in 2019. Choose SwiftUI specialists for new apps targeting iOS 15+ where you want faster development and easier maintenance. Choose UIKit/Swift specialists if you need iOS 13+ support, complex custom animations, or have specific third-party library requirements that aren't SwiftUI-compatible yet.

How long does iOS app development typically take?

MVP development takes 3-4 months for simple apps, 4-6 months for medium complexity, and 6-12 months for complex applications. These timelines include design, development, testing, and App Store submission. Add 2-4 weeks for App Store review and any required revisions.

What should I look for in an iOS development agency's portfolio?

Check for apps actually live in the App Store (not just mockups), consistent 4+ star ratings, recent releases showing ongoing maintenance, and apps in your industry or with similar technical requirements. Ask for client references and verify the agency built the core functionality, not just UI implementation.

How does Apple's App Store review process affect development?

Apple reviews take 24-48 hours on average but can extend to 7+ days during busy periods or for apps with complex features. Budget for 2-3 review cycles for initial submission. Common rejection reasons include incomplete metadata, privacy policy issues, and guideline violations. Experienced iOS agencies know these pitfalls and structure projects to avoid them.

Do iOS agencies handle both iPhone and iPad development?

Most iOS agencies build universal apps that work on both devices. However, iPad-optimized apps with split-view multitasking, Apple Pencil support, or tablet-specific layouts require additional design and development work. Expect 20-30% additional cost for comprehensive iPad optimization beyond responsive scaling.

What ongoing costs should I budget after iOS app launch?

Annual Apple Developer Program fee is $99. Server costs vary from $50-2,000+/month based on users. Plan for iOS version updates (typically $5,000-15,000 annually to maintain compatibility). Bug fixes and minor updates run $2,000-10,000/month depending on app complexity and user base size.

How do I verify an agency's iOS expertise is current?

Ask about their experience with SwiftUI, Swift Concurrency (async/await), and iOS 17/18 features. Request examples of apps using recent APIs like App Intents, WidgetKit, or VisionOS. Check if developers hold Apple certifications or speak at iOS conferences. Review their GitHub for Swift packages or open-source contributions.
