What services does A Major offer?

A Major offers web design, web app development, mobile app development (React Native, Swift, Flutter), SaaS product development, enterprise systems, UI/UX design, DevOps, performance optimization, MCP server development, AI agent infrastructure, MVP scoping, digital transformation, and engineering consultancy.

Where is A Major based?

A Major is based in Singapore and works with clients worldwide.

Do you work with international clients?

Yes. While headquartered in Singapore, A Major works with founders and businesses across Southeast Asia, Europe, and North America.

Ryu is an AI agent orchestration layer built by A Major. It enables teams to run, coordinate, and monitor AI agents at scale — connecting LLMs, tools, and workflows into reliable production systems.

Do you build MCP servers?

Yes. A Major builds Model Context Protocol (MCP) servers that connect AI agents to databases, APIs, and internal tools, enabling reliable LLM-powered workflows in production environments.

How much does iOS development cost?

Apple Developer Program costs $99/year. Xcode is free. Development costs depend on complexity — a simple app takes 4-8 weeks, a feature-rich app with backend integration takes 12-24 weeks. Universal apps (iOS + macOS) add 20-40% to the timeline.

Swift vs Flutter for iOS — which should I choose?

Swift gives you native performance, the latest Apple APIs (WidgetKit, App Clips, SharePlay), and the best possible iOS user experience. Flutter provides cross-platform from one codebase but may lag behind on platform-specific features. Choose Swift for iOS-focused apps.

Do I need a Mac for iOS development?

Yes. Xcode — Apple's IDE and the only way to compile, sign, and submit iOS apps — runs exclusively on macOS. A Mac is required for development, testing, and App Store submission.

Swift / iOS MobileNative iOS and macOS experiences

We develop iOS and macOS applications using Swift and SwiftUI — fully native apps that feel at home on Apple platforms, with deep system integration and App Store ready builds.

Swift is Apple's modern programming language for iOS, macOS, watchOS, and tvOS development. Combined with SwiftUI's declarative UI framework, it provides a powerful, type-safe development experience with deep integration into Apple's ecosystem — from WidgetKit and App Clips to CloudKit sync and StoreKit purchases. Swift's async/await concurrency model, Combine framework for reactive data binding, and the Xcode toolchain provide everything needed to build polished Apple platform apps. TestFlight distribution and App Store submission are built into the development workflow.

Quick start

bash

# Install Xcode from the Mac App Store
# Or via command line:
xcode-select --install

# Create a new SwiftUI project
# Open Xcode > File > New > Project > App
# Select SwiftUI for interface

SwiftUI with async/await

Declarative UI with structured concurrency — reactive state, custom view modifiers, and smooth animations.

Combine framework

Reactive data binding with Combine publishers — async pipelines that transform and deliver data to views.

Core Data + CloudKit

Local persistence with CloudKit sync — your users' data available across all their Apple devices.

WidgetKit

Home screen and lock screen widgets that surface your app's key information at a glance.

App Clips

Lightweight instant-launch experiences — users access core functionality without installing the full app.

TestFlight distribution

Beta testing with TestFlight and App Store submission — code signing, provisioning, and release management handled.

Why it's hard

SwiftUI version fragmentation

SwiftUI APIs differ between iOS versions. Supporting older iOS versions means conditional code or falling back to UIKit for features only available in newer releases.

App Store review process

Apple's review process can delay releases by days and reject apps for subjective reasons. Understanding App Store guidelines and having contingency plans is essential.

Code signing and provisioning

Apple's code signing, provisioning profiles, and certificate management is notoriously complex. Xcode manages much of this automatically, but CI/CD setups require careful configuration.

Best practices

Use SwiftUI for new projects

SwiftUI is Apple's recommended UI framework. Start new apps in SwiftUI and use UIKit only for features not yet available in SwiftUI.

Adopt async/await for concurrency

Swift's structured concurrency with async/await is safer and more readable than GCD or completion handlers — use it for all new async code.

Test with TestFlight early

Set up TestFlight distribution from day one — get beta feedback early and ensure your release pipeline works before launch.
