EtherWorld iOS
Designed the application architecture and modular structure for the EtherWorld iOS app — scalable navigation, API integration, and maintainable app structure.
Overview
A native iOS application developed for the EtherWorld platform that extends the website experience to mobile devices through seamless backend API integration and native application workflows.
Delivered a production-ready architecture for the EtherWorld mobile platform.
The Problem
EtherWorld users primarily accessed content through web browsers, limiting the overall mobile experience and discoverability within Apple's ecosystem. A native app was needed to reach a broader mobile audience.
Why I Built It
To deliver a native iOS experience while maintaining consistency with the existing platform and successfully publishing through Apple's deployment process.
Objectives
- Build a native iOS app consistent with the EtherWorld brand
- Integrate backend REST APIs for content delivery
- Architect for scalability and future feature additions
- Successfully deploy through App Store Connect
My Role
Developed the full iOS application, integrated backend REST APIs, built native user interfaces in Swift, managed App Store Connect deployment, and prepared TestFlight builds for review.
Architecture
SwiftUI handles declarative UI construction. A dedicated networking layer abstracts all API communication. Navigation uses a coordinator pattern for clean separation between routing and view logic. The data layer uses Combine for reactive state management.

Engineering Challenges
API Consistency
Ensuring the mobile app presented the same data as the web platform required careful API contract definition and response normalization.
App Store Review
Navigating Apple's review process required attention to metadata, content policies, and privacy disclosure requirements.
Navigation Architecture
Designing a navigation system that could scale to future features without refactoring required upfront architectural decisions.
Development Process
- 01Defined app information architecture and navigation flows
- 02Set up Xcode project with modular target structure
- 03Built networking layer with URLSession and Combine
- 04Developed core content views in SwiftUI
- 05Integrated backend APIs and tested data flows
- 06Prepared App Store metadata, screenshots, and privacy policy
- 07Submitted TestFlight builds and iterated on feedback
- 08Released through App Store Connect
Key Features
Native Content Browser
Native SwiftUI views for browsing EtherWorld articles and research content.
API Integration
Full backend integration delivering the same content as the web platform to mobile users.
Offline Reading
Cached content available for offline reading of previously loaded articles.
App Store Presence
Available on the Apple App Store with full iOS native experience.
Implementation Details
The app uses a coordinator pattern for navigation, separating routing logic from view controllers. API responses are decoded into typed Swift models using Codable. Combine publishers handle async state updates throughout the UI layer. The modular architecture allows independent development of new features.
Future Improvements
- Push notifications for new content and protocol updates
- Offline-first architecture with local caching database
- Widgets for home screen Ethereum news
- iPad-optimized layout
Lessons Learned
Apple's review process requires careful preparation — metadata and privacy policy are as important as the code
SwiftUI's declarative model makes complex UI significantly faster to build than UIKit
Architecture decisions made on day one are much harder to change once features accumulate
