Graduation Day

Look how far you've come

Twelve modules ago, let versus var was news. Now look at what you can read — and write:

• Swift itself — constants, optionals, structs, closures, enums, guard, defer (Modules 1–2)
• Codable models — the entire Models.swift, snake_case JSON and all (Module 3)
• SwiftUI — views, stacks, modifiers, @State, @Observable view models (Modules 4–5)
• A design system — the Brand tokens and fonts on every screen (Module 6)
• Networking & auth — APIClient, async/await, bearer tokens in the Keychain (Modules 7–8)
• Real screens — lists, navigation, booking flows, a live map (Modules 9–11)
• And today — an AI assistant that was, honestly, just all of the above again

That last point is the real graduation gift: the 'hardest' feature in the app introduced zero new concepts. That's what knowing a stack feels like — new features stop being new, and start being combinations.
