Swift

Scale with Swift experts

We build fast, refined Swift applications across Apple's platforms, native iOS, iPadOS, and macOS apps that feel at home on the device and perform beautifully.

This is for teams shipping a Swift app, whether that's a new consumer product, an enterprise app, or an existing Swift codebase that needs to feel faster and more stable.

Custom Swift Development Services

We build Swift apps that feel genuinely native, fast, stable, and at home on the platform. Clean architecture, smooth performance, and careful data handling are what we sweat, so the app clears review, wins users over, and stays maintainable release after release.

We do enterprise-grade iOS development for products that demand strict uptime, predictable performance, and carefully guarded data. From the first sprint our developers work with your backend, security, and design people to line up APIs, auth, and accessibility, setting latency budgets, instrumenting with MetricKit, and tying release windows to business events. The result is a resilient app that fits your architecture and ships safely at any hour.

How we help

We align APIs, auth, and accessibility from the first sprint, set latency budgets, and instrument with MetricKit so the app releases safely at any hour.

Years of incremental change leave large iOS apps with layout debt, accessibility drift, and general UI churn. We modernise the codebase by introducing SwiftUI where it speeds things up while keeping the critical UIKit surfaces stable, isolating the risky bits and staging adoption behind feature flags. What emerges is a cleaner UI layer that moves faster without upsetting production.

How we help

We introduce SwiftUI where it adds velocity, keep critical UIKit surfaces stable, and stage adoption behind feature flags to protect production.

A codebase split across two languages carries maintenance overhead, security gaps, and delivery friction. We modernise it by moving legacy Objective-C modules to Swift under measurable risk controls, inventorying APIs, setting version windows, and dual-running parity tests through phased cutovers. You come out with a future-ready codebase that runs across all Apple devices, and ongoing development never stops.

How we help

We inventory APIs, set version windows, and dual-run parity tests through phased cutovers so migration lands without halting development.

A monolithic Swift app slows the team, drags out build times, and breeds brittle dependencies. We give large codebases clear module boundaries and stable interfaces, defining domains, extracting XCFrameworks, standardising dependencies with SPM, and documenting contracts in CI, so teams can ship independently while runtime behaviour stays steady.

How we help

We define domains, extract XCFrameworks, and standardise SPM dependencies so teams ship on their own with steady runtime behaviour.

Enterprise distribution demands staged rollouts, signing discipline, and telemetry you can trust. We build and run reproducible build-and-release pipelines for iOS, build steps codified, test runs automated, TestFlight cohorts managed with rollback playbooks in hand. Releases become routine while we carry the heavy lifting underneath.

How we help

We codify build and signing steps, automate test runs, and manage TestFlight cohorts with rollback playbooks so releases become routine.

Regulated industries expect audit trails, data minimisation, and controlled access at every layer. We design Swift apps to meet HIPAA, SOC 2, ISO 27001, and GDPR, least privilege, secure storage, and SSO via OAuth or OpenID Connect, with evidence captured across the lifecycle. Your products clear their audits without the last-minute scramble.

How we help

We apply least privilege, secure storage, and SSO, and capture audit evidence across the lifecycle so products clear audits cleanly.

In data-heavy apps, slow launches, janky scrolling, and memory spikes quietly erode users' trust. We tune Swift codepaths for startup speed, memory efficiency, and frame stability, profiling with Instruments to sharpen concurrency and prove the gains under load. What you get is faster launches, smoother interaction, and fewer production incidents.

How we help

We profile with Instruments, target the startup, memory, and frame hotspots that matter, and validate gains under realistic load.

Field teams routinely work where the network is patchy or simply gone. We build robust offline experiences with conflict-aware sync, persistence models, batch writes, and retry policies designed deliberately, then integrity confirmed with chaos tests. So people keep working without losing progress or data when the connection drops.

How we help

We design the persistence model and conflict-aware sync deliberately and confirm integrity with chaos tests so offline work is never lost.

Swift experts, AI-augmented

The Swift toolset

The Swift tooling we rely on, grouped by what it does, and chosen deliberately from experience. Pick an area to see what we reach for and why.

We start from a stable foundation. Swift's core language features and Apple's first-party UI frameworks, which offer the strongest guarantees for long-term support, performance, and tooling integration.

Swift
SwiftUI
UIKit
Combine

To keep large applications maintainable, we hold clear architectural boundaries, tools that standardise module definitions, manage dependencies predictably, and let independent teams ship in parallel without conflict.

Swift Package Manager
XCFrameworks
Tuist
Bazel

Our toolkit standardises on mature, well-supported package managers for deterministic builds, security vulnerability scanning, and clear versioning, a secure, reproducible supply chain.

Swift Package Manager
CocoaPods
Carthage

We choose networking and persistence tools for their ability to produce predictable, strictly-typed, testable data flows, proven to handle poor network conditions gracefully.

URLSession
Alamofire
Codable
GRDB
SQLite
Core Data
gRPC Swift

We standardise on a multi-layered testing stack, mature frameworks for unit, UI, and snapshot testing, alongside static analysis that enforces code style and catches bugs before they merge.

XCTest
XCUITest
Quick
Nimble
SwiftLint
SwiftFormat

Our CI/CD toolchain standardises on platforms that give reproducible builds, automated signing, and controlled, phased rollouts, which makes the release process predictable.

Xcode
Xcode Cloud
GitHub Actions
Fastlane

Our instrumentation stack is built on industry-standard tools for profiling, crash reporting, and real-time app-health monitoring, chosen for low overhead and actionable data under production-like load.

Instruments
MetricKit
Firebase Crashlytics
Sentry

To meet security and compliance demands we rely on battle-tested tools and protocols, first-party Apple frameworks like Keychain and Secure Enclave for hardware-backed security, tied into established identity providers.

Keychain Services
CryptoKit
Secure Enclave
DeviceCheck
App Attest

We integrate directly with your design system, using tools that act as a single source of truth for design tokens, components, and specifications.
