Swift syntax, SwiftUI declarative views, @State and @ObservableObject data flow, URLSession networking, CoreData persistence, and submitting to the App Store. The Swift course for developers building their first iOS app.
This is a text-first course that links out to the best supporting material on the internet instead of trying to replace it. The goal is to make this the best course on swift you can find — even without producing a single minute of custom video.
This course is built by engineers who ship swift systems in production. It reflects how these tools actually behave at scale.
Every day includes working code examples you can copy, run, and modify right now. Understanding comes through doing.
Instead of re-explaining existing documentation, this course links to the definitive open-source implementations and the best reference material on swift available.
Each day is designed for about an hour of focused reading plus hands-on work. Do the whole course over a week of lunch breaks. No live classes, no quizzes.
Each day stands alone. Read them in order for the full picture, or jump straight to the day that answers the question you have today.
Variables and constants, type system, optionals and optional chaining, structs vs classes, closures, and the Swift patterns (guard, if let, switch exhaustiveness) that appear constantly in iOS code.
View protocol, VStack/HStack/ZStack, Spacer, padding/frame modifiers, List and ForEach, NavigationStack, and the declarative layout model that makes SwiftUI significantly different from UIKit.
@State for local view state, @Binding for two-way parent-child data flow, @Observable for shared model objects (Swift 5.9+), @Environment for injected values, and the data flow patterns Apple recommends.
URLSession with async/await, Codable for JSON decoding, error handling in async contexts, loading states in SwiftUI, and the networking patterns for REST APIs in iOS apps.
CoreData stack setup, @FetchRequest in SwiftUI, NSPredicate for filtering, Core Data migrations, Xcode archiving, TestFlight distribution, and the App Store Connect submission checklist.
Instead of shooting our own videos, we link to the best deep-dives already on YouTube. Watch them alongside the course. All external, all free, all from builders who ship this stuff.
Complete SwiftUI courses — views, layout, state management, and navigation for developers building their first iOS app.
Concurrency with async/await in Swift — URLSession, Task, and the modern Swift concurrency model that replaced completion handlers.
@State, @Binding, @Observable, and @Environment — Apple's recommended patterns for managing state in SwiftUI apps.
Setting up CoreData, CRUD operations, @FetchRequest in SwiftUI views, and data migration strategies.
Xcode archiving, TestFlight, App Store Connect, and the screenshots and metadata required for App Store review.
The best way to deepen understanding is to read the canonical open-source implementations. Clone them, trace the code, understand how the concepts in this course get applied in production.
Curated list of SwiftUI tutorials, components, and open-source apps — the best reference for SwiftUI patterns in real projects.
Community SwiftUI code examples covering common UI patterns — lists, forms, navigation, and animations.
The Swift compiler source. The /stdlib directory shows how Swift's core types (Optional, Array, Dictionary) are implemented.
A clean CoreData stack implementation with async context support and the migration patterns needed for production iOS apps.
SwiftUI makes iOS development accessible for the first time. This course gives you the fundamentals to go from Xcode setup to a submitted App Store app.
SwiftUI's declarative model is closer to React than UIKit was. This course helps web developers understand SwiftUI through concepts they already know.
Some iOS features require native Swift. This course gives React Native developers the Swift knowledge to drop to native when it matters.
