Level 1 · Entry Foundations

Goal: get comfortable reading and writing Swift, understand its core building blocks, and ship a small working program.

Modules

1. Setup & First Program
2. Variables & Types
3. Control Flow
4. Functions
5. Optionals Basics
6. Collections
7. Structs & Classes Basics
8. Enums
9. Closures Intro
10. Project — CLI To-Do App

By the end of this level you'll be able to write programs that take input, make decisions, store and process data with arrays/dictionaries/sets, handle absence of a value safely with optionals, and organize related data and behavior with structs, classes, and enums.
