Hire Swift developers to build and scale your software.

There is no single rate for Swift developers. Cost depends on the seniority you need, the engagement model you choose (adding developers to your team, a dedicated team, or a fixed-price project), how long the engagement runs and the scope of the work. For Swift work, the biggest drivers are the oldest iOS version the app must support, how many Apple frameworks and entitlements are involved, and whether an existing Objective-C or UIKit codebase needs modernizing alongside new features. Share your requirements and we will come back with a quote for your situation.

You tell us the technology, seniority, role and team structure you need. We recommend Swift developer profiles that match those requirements, and you review the profiles and speak with the engineers yourself before anyone joins your team. When you interview, the areas worth testing are swiftUI state ownership, data flow and view identity; mixing SwiftUI and UIKit in one app; async/await, actors and data-race safety; memory management, retain cycles and Instruments profiling; storeKit subscriptions and App Store review requirements; and swift Package Manager and modularizing an Xcode project.

It depends on which engineers with the right skills are available when you get in touch, so we do not publish a fixed start date. Availability is part of the conversation when we recommend profiles, and the start date is agreed with you before the engagement begins.

Because you interview the engineers before anyone joins, fit is tested before work starts. If concerns come up once the engagement is running, raise them with us directly. How changes to the team are handled is set out in the terms you agree with us at the start.

A freelancer suits small, well-defined tasks you can manage yourself. A dedicated developer joins your team under your direction. A dedicated team adds several roles around your product, and a project-based team delivers a defined outcome end to end.

Most new screens are faster to build in SwiftUI, and Apple's newest APIs increasingly arrive there first. UIKit still offers finer control for complex lists, custom transitions and older minimum iOS versions. Many production apps mix both, hosting SwiftUI views in UIKit or wrapping UIKit components for SwiftUI.

Swift and Objective-C coexist in one target through a bridging header and generated interface, so migration can happen file by file. We start with new features and well-tested modules, add nullability and generics annotations to remaining Objective-C headers, and avoid a full rewrite unless the old code blocks important work.

Frequent causes include crashes or broken links during review, missing demo credentials, selling digital content outside Apple's in-app purchase rules, vague permission prompts, and incomplete privacy details. Apps that let users create accounts must also allow account deletion in the app. Reviewing the guidelines before submission avoids most delays.

Common integrations include HealthKit for health data, MapKit and Core Location for maps, StoreKit for subscriptions and in-app purchases, Core Bluetooth for devices, and WidgetKit for home screen widgets. Each has its own entitlements, permission prompts and review expectations, which need planning early rather than at submission.

async/await replaces nested completion handlers with linear code, and actors protect shared state from data races. The main actor keeps UI updates on the main thread. Swift's strict concurrency checking catches many threading bugs at compile time, although adopting it in an older codebase is usually done module by module.

SwiftData offers a simpler, Swift-native API and integrates closely with SwiftUI, but it requires recent iOS versions. Core Data is mature, supports older devices and gives more control over migrations and performance tuning. Apps with an established Core Data model rarely gain enough from switching to justify the risk.

Yes. SwiftUI views and shared Swift packages can run across iPhone, iPad, Apple Watch and Mac, with layouts adapted for each device. A watchOS companion needs its own design for small screens and short interactions, and syncs with the phone app through WatchConnectivity or a shared backend.
