We've sourced engineers who test on real iPhones, not just simulators exclusively. They know Simulator performance doesn't predict actual device behavior accurately.
The Philippines has skilled iOS developers with excellent English proficiency and Apple ecosystem expertise. Developers own Apple devices and understand user expectations for quality iOS experiences. Cultural alignment ensures effective collaboration on consumer-focused applications.
Our iOS developers work hours overlapping US time zones by 6+ hours daily. Real-time collaboration happens during your core design and development hours. This proves essential during App Store submission issues requiring immediate response.
Schedule a call to discuss your iOS app requirements and design specifications. We’ll match you with developers experienced in Swift and your app’s complexity. Onboarding completes within one week typically.
Our developers build with Swift 5.x, SwiftUI for modern interfaces, and UIKit for mature applications. They integrate Core Data, CloudKit, HealthKit, and Apple Pay when needed. They implement push notifications, background tasks, and App Clips properly.
Yes, our developers build new features in SwiftUI while maintaining UIKit codebases seamlessly. They bridge between frameworks when necessary and choose the right tool for requirements. They understand SwiftUI’s limitations and when UIKit remains the better choice.
Absolutely, our developers design interactions matching iOS patterns users expect instinctively. They implement proper navigation, gestures, and animations following Apple’s standards. They understand consistency with system apps increases user comfort significantly.
Yes, our developers profile apps using Instruments, identify performance bottlenecks, and optimize rendering. They implement efficient background processing, minimize network calls, and reduce battery drain. They measure frame rates and ensure smooth 60fps scrolling.
Our developers manage the entire submission process including preparing screenshots, writing descriptions, and metadata. They handle provisioning profiles, certificates, and app signing correctly. They respond to review feedback and coordinate releases through App Store Connect.
Our developers write unit tests with XCTest, UI tests for critical user flows, and integration tests. They implement test-driven development when building complex business logic. They structure code for testability using dependency injection and protocols.
Yes, our developers implement networking with URLSession, Alamofire, or modern async/await networking. They handle authentication, parse JSON with Codable, and implement proper error handling. They optimize network calls and implement offline-first architectures when needed.
Our developers design Core Data models, implement migrations safely, and optimize fetch requests. They handle relationships, manage contexts properly, and implement background processing. They understand when Core Data fits versus when simpler persistence works better.
Yes, our developers implement StoreKit for in-app purchases, subscriptions, and receipt validation. They handle purchase restoration, subscription management, and App Store server notifications. They test purchases thoroughly using sandbox environments before production.
