Premium native iOS with Swift.

Native Swift is the choice when your app depends on Apple-exclusive APIs that Flutter doesn't yet support (advanced ARKit, deep HealthKit, App Clips, Live Activities, Dynamic Island), when design requirements are extremely precise relative to HIG, or when 90%+ of your users are on iOS and maximising that platform's experience justifies the additional cost over a cross-platform solution.

Our track record is over 95% approval on the first attempt. Apple rejections typically come from three sources: poorly documented data privacy, misuse of private APIs, or designs that violate HIG. We know these rules in detail and apply them from initial design, not as a patch at the end. If there is a rejection, we resolve it at no additional cost.

Yes, in two ways. If you need native apps on both platforms, we have iOS (Swift) and Android (Kotlin) engineers on the same team. If time-to-market or budget is a constraint, Flutter is our recommendation — a single codebase with near-native performance on both iOS and Android, managed by Spain's most knowledgeable Flutter team.

SwiftUI as the primary UI system (with UIKit for edge cases), Combine or Swift Concurrency for asynchronous state management, Swift Package Manager for dependencies, XCTest for unit tests and XCUITest for UI tests. MVVM architecture by default, with VIPER variants for enterprise apps with large teams. CI/CD with Xcode Cloud or Fastlane depending on the case.
