Some products deserve to be native. When your app needs every drop of iPhone performance — buttery scrolling, instant launch, deep hooks into the camera, HealthKit, or Apple Pay — Swift is the honest answer. Our iOS team at GTS Infosoft has been shipping to the App Store since the Objective-C days, and we've moved with the platform: SwiftUI for interface work, Swift Concurrency for clean async code, and TestFlight for every beta.
We're an ISO 9001:2015 certified studio based in India, 16 years in and 250+ apps shipped for clients across India, the USA and Australia. You get a dedicated Swift team from around USD 20/hr — senior engineers who've dealt with App Store review quirks, StoreKit subscriptions, and the occasional rejected build more times than we'd like to admit.

Frequently Asked Questions
How much does Swift iOS app development cost?
It depends on screens, integrations, and how custom the design is. A focused iOS MVP usually lands somewhere between USD 8,000 and 25,000 with our India-based rates starting around USD 20/hr; complex products cost more. Send us your idea and we'll return an itemized quote — free, no strings.
Should we use SwiftUI or UIKit?
SwiftUI for almost everything new — it's mature now, and it's where Apple is investing. We still reach for UIKit when a screen needs fine-grained control SwiftUI doesn't expose yet, or when we're extending an existing UIKit codebase. Most of our recent apps mix both, and that's normal.
When does native Swift make more sense than Flutter or React Native?
Go native when you're iOS-first, when performance and platform feel genuinely matter, or when you depend on deep Apple APIs — ARKit, HealthKit, CarPlay, widgets, live activities. If you need Android on day one with a tight budget, cross-platform is often the smarter call, and we'll tell you so.
How long does it take to build an iOS app in Swift?
A lean MVP typically takes 6-10 weeks including App Store submission. Feature-heavy products run 3-6 months. We work in two-week sprints with a demo at the end of each, so you're never guessing where things stand.
Do you handle App Store submission and updates after launch?
Yes. We manage the whole review process — provisioning, screenshots, privacy labels, and any back-and-forth with Apple's reviewers. After launch we offer maintenance retainers covering crash fixes, new iOS version support, and feature work.
