Hire Swift Developers — iOS & macOS Experts

Swift and React Native serve different needs. Native Swift development is the right choice when you need maximum performance, direct access to the latest Apple APIs (often available months or years before React Native community libraries), the deepest integration with the Apple ecosystem (HealthKit, ARKit, StoreKit 2, Shortcuts), or when the app has complex animations and custom UI that benefits from SwiftUI's declarative rendering model. Kultrix will help you choose the right approach during the scoping call.

Standard start time is 48 hours from contract signing. For developers with specific framework expertise — ARKit, HealthKit, or Core Bluetooth — one week is typical. We maintain bench capacity for standard iOS development at all times.

SwiftUI is our default for all new Apple platform development. It produces substantially less code, integrates naturally with Swift Concurrency and Combine, and Apple is clearly investing in its future. Our developers maintain strong UIKit competency for existing UIKit codebases and for scenarios where UIKit still outperforms SwiftUI — complex custom collection views, certain UIKit presentation styles, and minimum deployment targets below iOS 15.

Yes. We join existing Swift projects regularly — adding features, refactoring to SwiftUI from UIKit, modernising to Swift Concurrency from Combine or completion handlers, upgrading Swift versions, and improving test coverage. We start with a code review to understand the architecture and conventions before proposing any changes.

For SwiftUI projects, we use MVVM — it maps naturally to SwiftUI's data-driven update model and is the pattern Apple uses in their own sample code. For complex apps with intricate state machines or navigation logic, we apply The Composable Architecture (TCA) for predictable, testable, and composable state management. We document the architecture choice explicitly and avoid mixing patterns within the same codebase.

Swift Concurrency (async/await, actors, and structured concurrency) is our standard approach for all async work on Swift projects targeting iOS 15+. Actors eliminate data races at compile time, async/await produces linear, readable code compared to completion handlers, and Task groups enable safe parallel execution. We migrate legacy callback-based code to Swift Concurrency as part of any codebase modernisation engagement.

Yes. StoreKit 2 is a significant improvement over the original StoreKit and is our default for all new in-app purchase implementations. We configure products in App Store Connect, implement the purchase flow with proper loading and error states, validate transactions using the signed transaction model, manage entitlements, implement subscription status handling, and build a robust restore purchases flow. We keep up with the annual WWDC updates to StoreKit.

Yes. iPadOS support is increasingly important and requires deliberate layout decisions. Our developers use SwiftUI's adaptive layout system with NavigationSplitView for two-column layouts, size classes for responsive content, and multitasking support (Split View, Slide Over). We test on both simulated and real iPad devices to ensure the experience matches the larger screen's potential.

We write unit tests with XCTest for business logic and view model behaviour, using Swift's structured concurrency testing support for async code. UI tests with XCUITest cover critical user flows. Snapshot testing with swift-snapshot-testing prevents unintentional visual regressions. All tests run in CI via Xcode Cloud or Fastlane scan on every pull request.

Yes. Core ML allows on-device inference without network calls — important for privacy-sensitive applications and for features that must work offline. We integrate Core ML models for image classification, natural language processing, and custom model inference, handle model conversion from PyTorch or TensorFlow using coremltools, and implement Create ML workflows for on-device training where appropriate.

Yes. We build native macOS applications in SwiftUI, using AppKit when SwiftUI's macOS support is insufficient for a specific requirement. macOS development requires different considerations from iOS — menu bar architecture, keyboard shortcut management, window management, document-based app patterns, and Notification Center integration. We also build Mac Catalyst ports of iOS apps when a shared codebase approach makes sense.

We offer monthly retainer engagements (fixed hours per month, guaranteed availability, fixed monthly fee) and time-and-materials engagements (billed weekly against tracked hours). Both include weekly progress reports, transparent timesheets, and a dedicated account manager. Minimum engagement is one month. Full iOS app builds typically run two to six months; ongoing feature development often continues beyond the initial build.
