An iOS application that allows users to register, log in, and manage blogs with co-owner functionality. Built with SwiftUI using MVVM architecture, this app demonstrates clean architecture, API integration, secure authentication, and automated testing.
- Displays all blogs with Login and Register buttons.
- Any user can register and log in (no verification flow).
- JWT authentication for all secured endpoints.
- Add, edit, and delete blogs after login.
- Add a co-owner from the user list.
- Any co-owner can also edit or delete the blog.
- Built using MVVM for separation of concerns.
- Alamofire for API calls.
- Codable for parsing API responses.
- APIClient as the common gateway for all API requests.
- BlogService and UserService for domain-specific API logic.
- Login state handled with AuthManager.
- Secure token storage with KeychainHelper.
- Unit Tests for models and API response decoding.
- UI Tests for login/logout flow and navigation.

- JWT tokens are stored securely in Keychain.
- All API calls requiring authentication attach the token automatically.
- Unit Tests: Verify model decoding and authentication logic.
- UI Tests: Validate login/logout flow, navigation to Dashboard, and button accessibility identifiers.
- Backend APIs are hosted on Render Cloud:
- Blog CRUD endpoints
- User authentication & registration
- Co-owner management
- Clone the repository:
git clone https://github.com/shuvojoseph/BlogPost_iOSApp.git- Install dependencies (CocoaPods):
pod install- Open in Xcode:
open BlogPost_iOSApp.xcodeproj- Run on iOS Simulator or a real device.
- BlogService is now injected into view models (
BlogListViewModel,AddEditBlogViewModel,BlogDetailViewModel) instead of being accessed as a singleton directly. - AuthManager and APIClient remain singletons since they are globally shared managers.
- This demonstrates understanding of Dependency Injection (DI) and makes it easier to write unit tests or replace services in the future.
- The backend is hosted on Render and may go inactive after ~45 minutes of inactivity.
- If the backend is inactive, it may take ~2 minutes to start again.
- To activate the backend before using the app, open this link in a browser: https://blogpostspringboot.onrender.com/api/blogs
- Once the backend is active, you can use the mobile app to fetch or post blogs.
