Project ideas

• Build a SwiftUI + Combine RSS reader that fetches via URLSession, decodes with Codable, and persists with Core Data.
• Create a UIKit photo gallery using collection views, AVFoundation capture, and Keychain-backed login.
• Ship a TestFlight beta of a tip-calculator widget using WidgetKit, StoreKit in-app purchases, and Fastlane automation.
