iOS App Development Outsourcing Company

What we build

Our iOS developers build everything from consumer mobile apps to enterprise applications, from e-commerce platforms to productivity tools. They work with native iOS development using Swift or Objective-C, modern UI with SwiftUI or UIKit, and integrate with backend APIs, databases, and cloud services.

We've built everything from high-traffic social media apps to complex financial applications, from on-demand delivery platforms to healthcare management systems. Our developers understand that iOS isn't just a platform—it's an ecosystem with powerful tools, frameworks, and best practices, and they know how to use them effectively.

Technologies and frameworks

Our developers are proficient across the iOS ecosystem. They work with Swift as the primary language, understand modern iOS architecture patterns like MVVM, MVC, and VIPER. They build UIs with SwiftUI for modern apps or UIKit for traditional interfaces. They integrate with Combine for reactive programming, Core Data or Realm for local storage, and Alamofire or URLSession for networking.

On the backend integration side, they work with RESTful APIs, GraphQL endpoints, Firebase services, and cloud storage. They understand how to handle authentication, push notifications, offline storage, and background processing. They know how to optimize for performance, handle memory efficiently, and ensure apps work smoothly across different iOS versions and device capabilities.

Swift and modern iOS

Native iOS apps built with Swift, leveraging modern language features and best practices. Our developers write clean, maintainable code using Swift's features like optionals, protocols, generics, and async/await. They understand how to structure iOS projects, manage dependencies with Swift Package Manager or CocoaPods, and ensure code quality throughout the development lifecycle.

SwiftUI

Modern UI development with SwiftUI, Apple's declarative UI framework. Our developers build beautiful, responsive UIs with SwiftUI, understand state management, navigation, and theming. They know how to migrate from UIKit to SwiftUI, optimize for performance, and create reusable UI components. They understand how to work with Combine for reactive programming and build apps that feel native.

iOS Architecture Patterns

MVVM, MVC, or VIPER architecture patterns depending on app complexity. Our developers structure apps following iOS best practices, understand lifecycle management, and build apps that are testable, maintainable, and scalable. They know how to handle memory management with ARC, work with delegates and closures, and ensure apps perform well on different iOS versions.

Testing and quality

Unit tests with XCTest, UI tests with XCUITest, and end-to-end tests. Our developers write tests alongside features and maintain high code coverage. They understand how to test ViewModels, repositories, and UI components effectively. They know how to write integration tests and ensure apps work correctly across different scenarios and iOS versions.

Performance optimization

Apps that load fast and stay responsive. Our developers optimize app startup time, reduce memory usage, and ensure smooth animations. They profile regularly with Instruments, identify bottlenecks, and optimize for performance. They understand how to handle large datasets efficiently, optimize images, and ensure apps work well on older devices and different network conditions.

1. Discovery: We align on goals, app requirements, target audience, tech stack, and team size. We define success metrics, delivery cadence, and communication protocols. We understand your business requirements, design preferences, and performance goals.
2. Team assembly: We handpick iOS engineers matched to your requirements. You interview final candidates (typically 3–5 per role) and choose who fits best. We ensure the team has the right mix of iOS, Swift, and mobile development experience.
3. Onboarding: Developers ramp up on your codebase, iOS architecture, tools (Xcode, GitHub, CI/CD), and Definition of Done. They understand your coding standards, development processes, and business domain.
4. Integration: Developers join your standups, PR reviews, sprint planning, and design reviews. They function as embedded engineers, not a black box. They communicate regularly and transparently about progress and blockers.
5. Delivery: Sprint-based execution with clear goals, measurable outcomes, and regular demos to stakeholders. Developers deliver working features incrementally and iteratively, ensuring features are production-ready.
6. Scaling: Flex team size up or down based on priorities, roadmap changes, and budget constraints. We adjust the team as your needs evolve, whether you need more iOS developers or specialized skills like UI/UX design.

Native iOS expertise

Our developers understand iOS architecture, lifecycle, and best practices. They know how to build apps that work well across different iOS versions, screen sizes, and device capabilities. They understand iOS's permission system, background processing limitations, and how to optimize for battery life and performance. They're familiar with App Store guidelines and submission processes.

Swift and modern practices

Swift is the preferred language for iOS development, and our developers are Swift experts. They leverage Swift's features like optionals, protocols, generics, async/await, and concurrency effectively.
