What does your Swift staff augmentation service include?

We provide senior Swift engineers, Vapor backend specialists, QA automation analysts, and delivery managers who embed into your processes. They join your sprint ceremonies, follow your coding standards, and deliver features alongside your in-house team.

How fast can you ramp up Swift developers?

Our average ramp-up time is 10 business days from discovery to first commit. We shortlist vetted profiles with interview recordings, align time zones, and prepare an onboarding plan so engineers are productive in the first sprint.

Do your Swift teams cover multiple time zones?

Yes. We deliver overlapping coverage for North American and European teams. Daily standups typically overlap EST mornings and CET afternoons, and we coordinate pair programming sessions to keep collaboration fluid.

Can you support server-side Swift and integrations?

Our specialists build and maintain Vapor-powered APIs, integrate with payment and identity providers, and connect Swift services to AWS, Azure, and Google Cloud infrastructures. We also handle observability, CI/CD, and performance monitoring.

Do you have experience migrating UIKit apps to SwiftUI?

We have led multiple SwiftUI migrations, including a recent fintech wallet refresh that moved 62 UIKit screens to SwiftUI across 12 sprints. We manage the roadmap, modularization, and knowledge transfer so your team can continue iterating confidently.

Hire Swift Developers - Experienced Swift Developers

Swift Staff Augmentation

Developers who live and breathe the Apple ecosystem.

Our Swift guild was built to help product teams deliver native experiences without losing momentum. We combine senior Swift engineers, QA analysts, and delivery managers into augmentation pods that plug into your ceremonies and tooling. Whether you need to extend an existing squad or spin up a parallel track, we align with your sprint cadence and report the same KPIs as your internal engineers.

Because we run our own Swift initiatives—including internal R&D apps and contributions to the community—we stay current with Apple's Swift roadmap and the best practices shared across the Swift.org documentation. That context shows up in every delivery, from code quality to adoption of the latest SDK releases.

Embedded Delivery

We slot into your Jira boards, GitHub or GitLab repos, and CI/CD pipelines on day one. Expect clear weekly velocity reports, pair programming, and shared documentation.

Product Centric

Every Swift developer we assign has shipped customer-facing experiences—onboarding flows, monetization, accessibility, and App Store compliance are second nature.

Flexible Engagements

Scale from a fractional Swift architect to a dedicated squad with QA and DevOps support. Switch between models without renegotiating your agreement.

Why Swift? Why Now?

Fast, safe, and expressive—Swift is the modern iOS language.

Swift isn't just another programming language—it's the foundation Apple continues to invest in for every new framework and device. Adopting Swift means you inherit type safety, async/await, SwiftUI, SwiftData, and seamless interoperability with existing Objective-C or Kotlin Multiplatform code. We help you modernize without risking delivery deadlines or App Store stability.

Our augmented teams frequently support clients through critical milestones: introducing subscription monetization, preparing for major iOS releases, or rebuilding legacy UIKit screens with SwiftUI. We bring a tested playbook for feature flagging, phased rollouts, and analytics instrumentation that keeps leadership informed while we iterate.

Performance

Swift is fast—often faster than Objective-C. With structured concurrency, value types, and compiler optimizations, you get faster launch times and improved battery life. We monitor these metrics with Instruments and share performance dashboards as part of each release train.

Type Safety

Swift's type system prevents errors at compile time. The compiler catches type mismatches, null pointer errors, and other common bugs before they reach production. Combined with our emphasis on snapshot tests and crash analytics, you'll see fewer incidents and shorter MTTR.

SwiftUI

SwiftUI is Apple's modern framework for building user interfaces. You describe the UI declaratively and gain adaptive layouts, accessibility support, and animation primitives out of the box. We coach teams on integrating SwiftUI modules gradually alongside UIKit and Storyboards.

Modern Syntax

Swift's syntax is clean, expressive, and easy to read. Features like type inference, result builders, property wrappers, and generics make code concise and maintainable. Our teams document these patterns so your internal engineers can reuse them across modules.

What You Can Build with Swift

Swift developers can build:

iOS apps: Native iPhone and iPad apps with SwiftUI, UIKit, or hybrid stacks
macOS apps: Native Mac applications leveraging Catalyst or AppKit
watchOS apps: Apple Watch companions and complications with HealthKit integrations

tvOS apps: Apple TV experiences with casting, content feeds, and analytics
Server-side apps: Backend services, REST APIs, and dashboards powered by Vapor or Kitura
Enterprise apps: Regulated apps with MDM support, offline sync, and complex workflows

When Staff Augmentation Makes the Difference

Teams typically bring us in when they:

Need to accelerate a SwiftUI migration while maintaining legacy UIKit screens
Require extra capacity for security audits, HIPAA compliance, or in-app purchases
Want to stand up a Vapor API that mirrors existing Node.js or .NET functionality
Need reliable coverage during parental leave, product launches, or WWDC-related spikes

OUR STANDARDS

Swift apps that are fast, safe, and maintainable.

Clean, idiomatic Swift is the baseline. Our engineers follow shared coding guidelines, run SwiftLint and static analysis on every PR, and leave behind documentation so future teammates understand architectural decisions.

You also get proactive communication: release notes tailored for stakeholders, Loom walkthroughs for complex pull requests, and office-hours sessions with our practice leads whenever Apple ships something new. It's how we make sure engagements stay collaborative, not transactional.
