What you will gain after the course

  • Swift's Core Syntax - Variable/Constant Declaration, Data Types, Optional Handling

  • Functional Programming Basics - Pure Functions, Closures, Higher-Order Functions (map/filter/reduce) Application

  • Advanced Functional Patterns - Copy-on-Write, Generic, Protocol/Extension

  • Xcode Debugging and iOS Memory Management (ARC) Basics

Learning Objectives

  • Understanding the overall Xcode environment (Xcode 3→16) and the iOS memory model (ARC)

  • Master the core of Swift grammar (variables, constants, data types, optional)

  • Strengthening the ability to utilize functional programming fundamentals (pure functions, closures, higher-order functions)

  • Understand advanced functional patterns through Copy-on-Write, generics, Protocol/Extension, etc.

Expected results after taking the course

  1. Write reliable Swift code : From optional safety to memory management, develop coding habits that reduce runtime errors.

  2. Applying a highly reusable functional style : Using pure functions and higher-order functions, you can express complex logic concisely and greatly improve maintainability.

  3. Increased Productivity : Master Xcode debugging tools and functional error handling techniques to quickly catch bugs and speed up stable app development.

Learn about these things

Understanding Xcode & iOS Environment

We will cover the following contents in detail according to your learning objectives.

  • Xcode 3→16 : A glance at the main features and UI changes by version

  • Memory Management (ARC) : Understanding ARC Operation Principles and Forced Release (weak, unowned)


Swift Basic Grammar & Functional Introduction

Let's explain the contents below in detail according to the learning objectives.

  • Grammar Core : Variables (let/var), data types, Optional safety handling (guard, if let)

  • Pure Functions & Closures : Writing Functions Without Side Effects and Basic Closure Syntax

  • Setting up a hands-on environment : Run Swift code right away with Playground

Key words – Immutability & Type Safety

Let's explain the contents below in detail according to the learning objectives.

  • let vs var : Strategies for managing immutability and mutability

  • Basic data types : Int, String, Bool, etc. Type inference

  • Optional Handling : How to Use if let , guard let , and nil Coalescing Operators

Pure Functions & Closures

We will cover the following contents in detail according to your learning objectives.

  • Pure functions : guarantee input → output without side effects

  • Function Composition : Composing complex logic by combining simple functions

  • Closure Grammar : Shorthand Parameters and Trailing Closure Usage

Higher order functions & optimization

Depending on your learning objectives, we will focus on the following contents.

  • map · filter · reduce : Practice the most frequently used higher-order functions

  • Practice Performance Optimization Methods

  • Custom Higher-Order Functions : Tailored Practice for Different Situations
