Learn Swift: Build iOS Apps

Learn Swift and build real iOS apps — no experience needed.
Bite-sized Swift and SwiftUI lessons, a real code editor on your phone, and an AI mentor that answers your questions in seconds.
Made for complete beginners and for developers coming to iOS from another language.

WHY LEARN SWIFT?
• Swift is the language of the Apple ecosystem — iPhone, iPad, Mac, Watch and Vision Pro apps are built with it
• iOS developers are among the best-paid mobile engineers — Swift is a career skill, not just a hobby
• SwiftUI makes modern app UIs dramatically simpler — learn the current way, not the legacy way
• Swift is friendly to beginners: readable syntax, safe by design

WHAT YOU'LL LEARN
• Swift fundamentals — variables, types, functions, optionals and closures
• Object-oriented and protocol-oriented programming
• Structs, classes, enums and error handling
• SwiftUI — views, state, layout and navigation
• Working with data: collections, JSON and app logic
• Concurrency basics — async/await explained simply
• Interview-style practice problems to test your skills

EVERYTHING YOU NEED TO LEARN SWIFT
✔ AI Mentor — stuck on optionals or a compiler error? Ask anything and get a clear answer in seconds
✔ 100+ bite-sized lessons (5–10 minutes each) — built for commutes and coffee breaks
✔ Real code editor — write and run Swift code right on your phone, no Mac required to start learning
✔ Quizzes and coding challenges after every topic to lock in what you learn
✔ Weekly Code Challenge — compete with learners around the world
✔ Certificate of completion — pass the final exam and prove your skills
✔ Streaks, progress tracking and smart reminders to keep you consistent
✔ Learn on the go — lessons load fast and keep working on flaky connections

WHO IT'S FOR
• Total beginners who dream of shipping an app to the App Store
• Web or Android developers adding iOS to their toolkit
• Students preparing for mobile developer roles and interviews

YOUR PATH TO THE APP STORE
Start with syntax, graduate to SwiftUI screens, then put it all together with app-logic lessons and interview-style challenges. By the end you'll read real Swift codebases with confidence — and know exactly what to build first in Xcode.
