Swift engineering for polished native iOS apps
Codersarts builds and maintains native iOS apps in Swift for startups, product companies and enterprises. Our iOS engineers design SwiftUI interfaces, connect apps to your APIs, add payments, notifications and offline support, modernize older UIKit and Objective-C code, and take apps through App Store review to release, so your iPhone and iPad experience feels fast and native.
What Is Swift Development?
Swift development is the building of apps for Apple platforms with Swift, Apple's modern programming language. It covers SwiftUI and UIKit interfaces, Swift concurrency, networking, local storage with SwiftData or Core Data, push notifications, in-app purchases, widgets, testing, App Store submission and the migration of older Objective-C code.
Native Swift apps get the best performance, the newest Apple features on day one and the platform look users expect. They suit products where the iPhone experience is central to the business.

Frequently Asked Questions
What Swift services does Codersarts provide?
We provide native iOS app development, SwiftUI interfaces, app modernization, API integration, in-app purchases, Apple platform features, App Store release and maintenance.
Should we build native Swift or cross-platform?
Choose Swift when the iOS experience, performance or newest Apple features are central. Choose Flutter or React Native when one codebase for iOS and Android matters more.
Can you convert our Objective-C app to Swift?
Yes. We migrate screen by screen, so the app keeps working and shipping during the move.
Do you handle App Store submission?
Yes. We prepare the listing, privacy details and builds, and fix any review issues.
Can you add subscriptions to our iOS app?
Yes. We implement StoreKit subscriptions with receipt validation on your server.
Can you fix crashes in our existing iOS app?
Yes. We review crash reports, find root causes and release fixes quickly.
Can you build the back end too?
Yes. We build APIs, push notifications and admin tools to support the app.
