Project Overview:

GitHub Followers lets you see who you're following and who's following you.

What I’ve done in Swift

• Built API connections for pulling data like images, usernames, number of account followers, & more
• Cached images from API calls to eliminate unnecessary network calls with NSCache
• Custom Error message displays based on individual network errors
• Maintained professional internal organization with proper folder structures
• Managed updates to Collection View’s dataSource and UI in a simple, efficient way with the UICollectionViewDiffableDataSource class
• Handled error messages using the efficient switch / case .success, .failure method
• Designed UI layouts with NSLayoutConstraint that are considerate of view.safeAreaLayoutGuide
• Used mathematical procedures for designing NSLayoutConstraint
• Implemented Pagination using UIScrollView and UIRefreshControl within the UICollectionViewDelegate extension for infinite scrolling, but only when content exceeds threshold to avoid unnecessary network calls for app efficiency
• Generated loading screen when making network calls using activityIndicator.startAnimating()
• Designed and created Empty State View Controller
• Created search functionality using the UISearchController() protocol
• Eliminated undesired native design options, such as the tinted x  when activating search: .obscuresBackgroundDuringPresentation = false
• Used the W?T:F method for checking which array to search
• Used Child View Controllers to take advantage of Lifecycle Methods, Self Contained, Flexible Context, and for Reusability

Objectives:

Allow user to quickly see who their GitHub followers are with an intuitive UI.

Learn API calls, custom design error messages, and appropriate handling

Scope of Work:

• API integration for user data (images, usernames, follower counts).
• Caching with NSCache.
• UI design using NSLayoutConstraint.
• Loading screens and Empty State View Controller.
• Search functionality with UISearchController.
• Data management with UICollectionViewDiffableDataSource.
• Pagination and infinite scrolling.
• Custom error messages and structured error handling.
• Clean project structure and use of Child View Controllers.

Timeline: 2 weeks total (1 week development, 1 week testing and launch).

Success Criteria: Smooth navigation, efficient network usage, and positive user feedback.
