Learn Swift vs DailySec

Learn Swift by writing it. This Swift programming course pairs every short lesson with code you edit and run in the built-in editor, so the language sticks instead of staying theory. Start from zero or pick up where you are: the path goes from your first let and var to protocols, generics, SwiftUI and the tools real iOS apps are built with. SWIFT PROGRAMMING, STEP BY STEP • 122 courses and 409 short lessons, from beginner (A1) to advanced (C2) • Basics: variables, types, strings, operators, loops, switch and pattern matching • Optionals done right: optional binding, guard, optional chaining and nil coalescing • Structs, classes and enums, value vs reference types, protocols and extensions • Closures, higher-order functions, generics, property wrappers and result builders • Error handling, Codable and JSON, dates, file I/O and the Swift Package Manager • Concurrency explained: async/await, structured concurrency, task groups, actors and Sendable • Memory management and ARC, unsafe pointers, macros and performance SWIFTUI AND IOS APP DEVELOPMENT • SwiftUI tutorial: views, modifiers, state, stacks, grids, bindings, environment, animations and custom layouts • iOS topics: UIKit in SwiftUI, Core Data and SwiftData, URLSession networking, Core Location and MapKit, push notifications, widgets and app extensions, Keychain, localization • Architecture: MVVM, coordinators, dependency injection, clean architecture and TCA • Testing and shipping: XCTest, Instruments profiling, distribution and CI • Server-side Swift with Vapor, plus Combine fundamentals SWIFTUI PLAYGROUND • Write a view and see a live preview on your phone, no Mac needed to experiment • Stacks, text, buttons, images, lists and @State are rendered on the device • Unsupported syntax is reported with the line number, so you always know why CODE EDITOR AND SWIFT COMPILER • Write code in the editor and run it on a Swift compiler in the cloud (internet required) • The editor runs command-line Swift; screens are previewed in the SwiftUI Playground • Tap a compiler error to jump to the line and get a plain explanation of how to fix it • Save your code and come back to any lesson later PRACTICE, PROJECTS AND INTERVIEW PREP • 60 coding missions, from easy to hard • 20 guided projects and 6 multi-step build-along projects • 50 quiz questions with an explanation for every answer • 50 Swift interview questions for iOS developer job prep, plus a daily interview question • A 77-entry cheat sheet to look up syntax fast • Swift Recall: the questions you miss become flashcards, reviewed with spaced repetition • World Coding Challenge: three global coding rounds every day AI MENTOR • Stuck on optionals or a compiler error? Ask the AI Mentor and get a clear answer in seconds • Free users get one AI Mentor question a day; Pro removes the limit CERTIFICATE • Pro members can take the final exam and earn a certificate of completion WHO IT'S FOR • Beginners learning their first programming language • Web or mobile developers moving to iOS development • Students and developers preparing for iOS developer interviews • Anyone who wants hands-on coding practice on the phone The app is available in 22 languages. FREE AND PRO Free to start: the first course, the first guided project, two missions, the playground basics, daily Recall practice and one AI Mentor question a day are free. The free version shows ads. Pro unlocks every course, project and mission, the full playground, the certificate exam and unlimited AI Mentor, and removes ads.
