Live Activities in iOS 16+ allow apps to display real-time information on the Lock Screen and Dynamic Island without requiring users to reopen the app. This tutorial demonstrates implementing Live Activities in SwiftUI by building a Water Tracker app that shows progress updates. The implementation involves creating a widget extension, defining ActivityAttributes for data structure, building the Live Activity view for different display contexts, and managing the activity lifecycle through a dedicated manager class. The tutorial covers the complete setup from UI design to enabling Live Activities in Info.plist.
