Dedicated iOS Swift engineers
Hire Swift developers who ship iOS apps that survive App Review and real devices
Grape5 places pre-vetted, India-based Swift developers with US companies building iOS, iPadOS, and macOS apps. Each engineer is screened by senior Grape5 engineers on live code, system design, and communication, then dedicated to your product. Expect at least 4 hours of daily overlap with US hours and a start in 2 to 3 weeks.
In short
Grape5 places pre-vetted, India-based Swift developers with US companies building iOS, iPadOS, and macOS apps.
Each engineer is screened by senior Grape5 engineers on live code, system design, and communication, then dedicated to your product. Expect at least 4 hours of daily overlap with US hours and a start in 2 to 3 weeks.
When to hire Swift developers
- Rewriting a sluggish React Native or aging Objective-C app into native SwiftUI because crash rates and scroll jank drove users away.
- Building a new consumer iOS app from scratch with SwiftUI, StoreKit 2 subscriptions, and push notifications, then getting it through App Review.
- Adding a native iOS client to an existing web product: wiring it to your API with URLSession and async/await, and handling offline with Core Data or SwiftData.
- Cleaning up an app a freelancer abandoned: memory leaks, main-thread stalls, broken code signing, and repeated App Store rejections.
How we vet Swift developers
Every engineer we put forward is screened by a senior Grape5 engineer before you meet them. For Swift developers, we look specifically at:
- Swift concurrency under real load: candidates reason about actors, Sendable, and async/await, spot data races, and explain why blocking the main actor freezes the UI.
- Memory discipline: finding and fixing retain cycles from strong self captured in closures and delegate references, and choosing weak vs unowned correctly under ARC.
- SwiftUI and UIKit judgment: state ownership with @State, @StateObject, and @Observable, view identity and diffing, and knowing when to drop to UIKit via UIViewRepresentable.
- Profiling with Instruments: reading Time Profiler and Allocations to kill main-thread hangs and scroll hitches, keeping frame pacing smooth on older devices.
- Shipping reality: code signing, provisioning profiles, entitlements, privacy manifests, and the App Review rejection reasons that actually bite, like ATT and background modes.

Frequently asked questions
Swift and Xcode only run on macOS, so our engineers develop on Macs and test on the iOS Simulator plus physical devices. Your Apple Developer account and signing certificates stay under your ownership, and the developer works inside them rather than holding anything critical themselves.
Both, depending on your app. SwiftUI is the default for new screens and moves fast, but UIKit still wins for complex lists, custom transitions, and older iOS targets. A strong Swift developer mixes them and tells you why instead of forcing one everywhere, and we screen for that judgment during vetting.
The developer can drive the whole release: certificates, provisioning profiles, entitlements, TestFlight builds, and the submission itself. You keep ownership of the Apple Developer account and app records, so nothing lives only with one person. We check for real App Review experience when we vet.
At least 4 hours of daily overlap with US working hours, so you can run standups, review builds, and coordinate a release together in real time. The rest of the day is heads-down build time on your product.
You get a free replacement. The engineer is dedicated to your product and managed and backed by Grape5, so if the match is wrong on skill or communication we swap them. You are not left negotiating with a freelancer who went quiet. Typical start is 2 to 3 weeks.
