Project ideas

  • Build a SwiftData-backed task manager with NavigationStack, swipe actions, and @Observable view models.
  • Create an animated onboarding flow using matchedGeometryEffect, custom transitions, and TabView paging.
  • Make a movie-search app that hits a REST API with async/await URLSession, decodes via Codable, and renders a LazyVGrid.
