Bootcamp
A two-week sprint to be productive in Swift and SwiftUI on Apple platforms.
Bootcamp plan
EXAMPLE
# Swift bootcamp - 10 working days Day 1 - Tooling: Xcode, swift package manager, swift CLI. Day 2 - Language: optionals, value vs reference, protocols, generics. Day 3 - SwiftUI basics: View protocol, modifiers, state, binding. Day 4 - Layout: stacks, grids, geometry reader, alignment guides. Day 5 - Navigation: NavigationStack, sheets, fullScreenCover, deep links. Weekend project: a small list-detail app with mock data. Day 6 - State + data flow: @State, @Binding, @Observable (Swift 5.9+), @Environment. Day 7 - Concurrency: async/await, Task, MainActor, structured concurrency. Day 8 - Persistence: SwiftData (or CoreData if you target older OS). Day 9 - Networking: URLSession async APIs, Codable, error handling. Day 10 - Testing + release: XCTest, snapshot tests, TestFlight upload. Capstone: ship a SwiftUI app to TestFlight. ## Tips - Use @Observable over ObservableObject if you target iOS 17+ - SwiftUI previews are your tightest feedback loop - keep them green - Read Apple sample code, especially the WWDC sessions, before reaching for blog posts
Why it matters
Swift evolves quickly. Stay on the latest tools, use @Observable when you can, and lean on the new structured concurrency model rather than completion handlers.
Tip: Tweak the snippet with Try it Yourself », then sit the quiz at the bottom of the page.
