A cleaner way to hire Swift developers

Hire Swift developers through Krapton to build and maintain native iOS apps that feel at home on Apple platforms and are built with App Store review rules in mind. A senior Swift developer today works mostly in SwiftUI with the Observation...

  • Concurrency without data races

    Swift 6 strict concurrency checking flags shared mutable state at compile time. Your developer migrates modules incrementally, isolates UI work to the main actor, uses actors for shared caches, and resolves Sendable warnings properly instead of silencing them with unchecked conformances.

  • SwiftUI with UIKit fallback

    SwiftUI covers most screens now, but complex text editing, some collection layouts and legacy screens still benefit from UIKit. A Krapton developer mixes the two with UIViewRepresentable and hosting controllers, keeping navigation and state ownership clear across the boundary.

  • Release pipeline ownership

    Code signing, provisioning profiles, build numbers, privacy manifests and App Store Connect metadata are where releases stall. Your developer automates them with fastlane or Xcode Cloud, runs tests on every pull request, and ships TestFlight builds your team can review.

  • Performance measured in Instruments

    Hitches, launch time and memory are profiled with Instruments and tracked with MetricKit in the field. The developer fixes expensive SwiftUI body recomputation, main-thread image decoding and retain cycles, then checks the improvement on older supported devices, not just the newest iPhone.

Why Swift?

What makes Swift the right choice for modern engineering teams.

  • Versatile and interpreted language

    Swift is a versatile, compiled programming language developed by Apple for building iOS, macOS, watchOS, and tvOS applications.

  • Safety and performance

    Swift prioritizes safety and performance, incorporating modern features like optionals, type inference, and memory management enhancements.

  • Interactive playground

    Swift includes interactive playgrounds that enable developers to experiment, visualize code execution, and learn Swift concepts interactively.

  • Swift Package Manager

    Swift Package Manager simplifies the management of dependencies and facilitates the creation, sharing, and distribution of Swift packages.

  • Syntax clarity and readability

    Swift emphasizes clear and expressive syntax, making code easy to read, write, and maintain.

What you can build with Swift

  • Subscription apps

    StoreKit 2 purchase flows with transaction verification, App Store Server Notifications handled by your backend, introductory offers, and paywalls tested in Xcode’s StoreKit testing environment before review.

  • Health and fitness apps

    HealthKit reads and writes with granular permissions, background delivery for new samples, workout sessions on Apple Watch, and charts built with Swift Charts that stay readable on small screens.

  • Widgets and Live Activities

    Home Screen and Lock Screen widgets with WidgetKit timelines, interactive buttons through App Intents, and Live Activities updated by push for deliveries, rides or match scores.

  • Offline-first data apps

    Local persistence with SwiftData or Core Data, sync through CloudKit or your own API with conflict rules defined up front, and background tasks that refresh data without draining the battery.

  • Camera and on-device ML

    AVFoundation capture pipelines, Vision for text and barcode recognition, and Core ML models running on the Neural Engine, keeping sensitive images on the device instead of uploading them.

  • Modular app architecture

    Feature modules as local Swift packages, dependency injection that keeps views previewable, and an architecture such as MVVM or The Composable Architecture chosen for your team’s size and testing needs.

What separates solid Swift apps from fragile ones

Most fragile iOS apps share a few root causes. State lives in too many places, so a SwiftUI view reads a stale copy and the UI disagrees with the server. Networking code runs on whatever thread happened to call it, which Swift 6 now surfaces as concurrency errors that teams are tempted to silence with @unchecked Sendable or nonisolated(unsafe). Images decode on the main thread and lists stutter on older devices. Release builds behave differently from debug builds because timing changes under optimization expose race conditions. A Krapton Swift developer addresses these at the architecture level: one source of truth per feature, a networking layer built on URLSession async APIs with typed errors and cancellation, image loading that downsamples off the main actor, and release-configuration test runs in CI so optimization surprises appear before TestFlight rather than after.

Choosing native Swift is a business decision as much as a technical one. It is the right call when the product depends on Apple-specific capabilities such as widgets, Apple Watch, HealthKit, CarPlay, App Intents for Siri and Shortcuts, or demanding camera and graphics work, and when iOS users are the revenue core. It is harder to justify for a content or forms app that must ship to Android at the same time on a tight budget, where React Native, Flutter or Kotlin Multiplatform with shared business logic may serve better. Apple’s annual cycle also shapes the work: each June brings new APIs and each fall a new iOS release with deprecations and changed review requirements, so the developer tests against beta SDKs over the summer and keeps the minimum deployment target under deliberate review.

Swift in action

import Foundation

// Define a 'Person' struct
struct Person {
    var name: String
    var age: Int

    // Function to display info about the person
    func displayInfo() {
        print("Name: (name), Age: (age)")
    }

    // Function to check if the person is an adult
    func isAdult() -> Bool {
        return age >= 18
    }
}

// Creating instances of 'Person'
let person1 = Person(name: "Alice", age: 24)
let person2 = Person(name: "Bob", age: 17)

// Using the struct's methods
person1.displayInfo() // Output: Name: Alice, Age: 24
person2.displayInfo() // Output: Name: Bob, Age: 17

// Checking if the person is an adult
if person1.isAdult() {
    print("(person1.name) is an adult.")
} else {
    print("(person1.name) is not an adult.")
}

if person2.isAdult() {
    print("(person2.name) is an adult.")
} else {
    print("(person2.name) is not an adult.")
}

What our Swift developers know

Every Krapton developer is vetted with real production experience in Swift across multiple industry domains.

Hire a developerSchedule a call
  • Swift programmingProficient in Swift programming, including syntax, data types, functions, and control flow.
  • Playground usageExpertise in using Swift Playgrounds for interactive development, experimentation, and learning.
  • Swift Package ManagerMastery of Swift Package Manager for dependency management and package creation.
  • Xcode proficiencyProficient in using Xcode, the official IDE for Swift development, for coding, debugging, and interface design.
  • Cocoa touch integrationExperience in integrating Swift code with the Cocoa Touch framework for iOS app development.

What our Swift developers go deep on

  • SwiftUI state and navigation

    @Observable models, @State and @Environment ownership, NavigationStack with typed paths for deep links, and avoiding view identity mistakes that reset state or trigger needless re-renders.

  • Swift concurrency and actors

    Structured concurrency with task groups, cancellation that actually propagates, MainActor isolation, custom actors for shared state, and AsyncSequence streams replacing much of what Combine handled before.

  • Testing Swift code

    Swift Testing with @Test and #expect for new suites, XCTest where existing, XCUITest for critical flows, snapshot tests for SwiftUI views, and protocol-based fakes for networking and persistence.

  • Security and privacy on iOS

    Keychain for secrets, CryptoKit for encryption, App Transport Security kept strict, privacy manifests and required-reason APIs declared accurately, and App Tracking Transparency prompts only where tracking genuinely occurs.

  • Dependencies and modularization

    Swift Package Manager for third-party and internal packages, a plan for leaving CocoaPods now that the project has announced a read-only trunk, and build-time tuning so incremental builds stay fast.

  • Accessibility and localization

    Dynamic Type that does not break layouts, VoiceOver labels and actions, sufficient contrast in light and dark modes, String Catalogs for localization, and right-to-left layout checks.

Common Swift projects we deliver

  • Migrating an Objective-C app to Swift

    Mixed-language targets let the work proceed screen by screen. The developer sets up bridging headers, rewrites leaf modules first, adds nullability annotations so Swift sees accurate optionals, and retires Objective-C code only once tests cover the behavior.

  • Moving a UIKit codebase to SwiftUI

    Rather than a rewrite, new features land in SwiftUI hosted inside the existing navigation, shared state moves to @Observable models, and UIKit screens are converted when they next need significant changes, so releases continue throughout.

  • Adopting Swift 6 strict concurrency

    Turning on complete checking in a large app produces many warnings. The developer enables it module by module, annotates main-actor UI code, converts callback APIs to async/await, and replaces ad hoc DispatchQueue locking with actors where it simplifies ownership.

  • Fixing crashes and poor App Store ratings

    Crash clusters in Xcode Organizer or Crashlytics are triaged by impact, symbolicated, reproduced with sanitizers enabled, and fixed with regression tests; the developer also reviews hang reports and adds rating prompts at sensible moments.

Swift solutions by industry

  • Health and wellness

    Apps built on HealthKit and Apple Watch data, where permission handling, on-device processing and App Store health data rules shape the architecture.

  • Fintech

    Banking and payment apps that need Keychain storage, Face ID with LocalAuthentication, certificate pinning where justified, and Apple Pay integration through PassKit.

  • Retail and commerce

    Shopping apps with fast product browsing, Apple Pay checkout, push campaigns, App Clips for in-store moments and Live Activities for order tracking.

  • Media and audio

    Streaming and podcast apps using AVKit, background audio, AirPlay, offline downloads and Now Playing controls that behave correctly on the Lock Screen and CarPlay.

Swift vs React Native

Native Swift and React Native solve different problems. Swift gives the best access to Apple frameworks, the most predictable performance and day-one support for new iOS features, at the cost of a separate Android codebase. React Native shares most code across platforms and suits teams with React skills. Products leaning on widgets, watch apps, camera or on-device ML usually justify native Swift.

Hiring Swift developers — answered

Practical answers to the questions CTOs and founders ask us most often before they hire.

How quickly can I hire a Swift developer from Krapton?

Within 24 hours of the initial call. We keep a bench of pre-vetted Swift engineers, so once you confirm the brief we line up two or three shortlisted CVs within a business day and can onboard the selected developer within two.

How much does it cost to hire a dedicated Swift developer from India?

Blended hourly rates for senior Swift engineers typically fall in the $22–$45 USD range depending on seniority and engagement length. Dedicated developers are billed monthly with no lock-in.

Are your Swift developers full-time employees or freelancers?

Every Swift developer you hire through Krapton is a full-time, in-house engineer — we never subcontract to freelancers or agencies. That means consistent code quality, signed NDAs, and a single point of accountability for your project.

Who owns the code and IP my Swift developers write?

You do — 100%. IP assignment and confidentiality are covered by the contract and a free NDA on request. All code lives in your repositories, on your infrastructure, under your accounts from day one.

What should I expect from a senior developer when I hire Swift developers?

Expect fluency across SwiftUI, Swift concurrency and the release process, not just syntax. A senior Swift developer can explain view identity and state ownership, migrate code to Swift 6 strict concurrency, profile with Instruments, write tests in Swift Testing or XCTest, and handle signing, privacy manifests and App Store review feedback. They should also know when UIKit is still the better tool for a specific screen.

Should we build natively in Swift or use React Native?

Build in Swift when the app depends on deep Apple platform features or top-tier performance, and consider React Native when shipping iOS and Android together from one team matters more. Many products start cross-platform and add native Swift modules for widgets, extensions or performance-sensitive screens. The developer reviews your roadmap for platform-specific features before recommending either, because changing direction after launch is expensive.

Can you migrate our Objective-C or UIKit app to Swift and SwiftUI?

Yes, and it is done incrementally so the app keeps shipping. Objective-C and Swift coexist in one target, as do UIKit and SwiftUI, so the developer converts leaf modules and new features first, adds tests around the screens being replaced, and leaves stable legacy code alone until it needs changes. A full rewrite is recommended only when the existing architecture blocks nearly every new feature.

How do you test and secure a Swift iOS app?

Both are built into the pipeline rather than saved for a final pass. Unit tests in Swift Testing or XCTest cover business logic, XCUITest covers sign-in, purchase and other critical flows, and snapshot tests catch visual regressions. For security, secrets live in the Keychain, network traffic stays on TLS under App Transport Security, sensitive screens hide content in the app switcher, and dependencies are reviewed before each release.

How do you handle new Swift and iOS versions each year?

New versions are tracked from the June betas, so the app is ready when the fall release ships. The developer builds against beta SDKs, fixes deprecations and new warnings, tests on beta devices, and adopts new APIs behind availability checks so older supported iOS versions keep working. Swift language upgrades follow the same pattern, with strict concurrency and new language modes enabled module by module rather than across the whole app at once.
