This repo is intended for educators and developers alike. It provides rich, hands-on examples covering a wide range of Swift topics, including:
- Basic syntax and string interpolation
- Arithmetic operations and operator overloading
- Advanced collection operations with arrays, dictionaries, and sets
- Control flow mechanisms like conditionals, loops, and switches
- Function definitions with various parameter types and return values
- Extensive coverage of closures, including callbacks and asynchronous usage
- Working with enums, structs, and classes to build data models
- Property observers and computed properties
- Methods, subscripts, inheritance, and initialization/deinitialization
- Error handling with custom error types
- Swift’s new concurrency model with async/await
- Type casting, nested types, extensions, protocols, and generics
- Advanced topics like opaque types, ARC, and access control
Each section is self-contained and includes comprehensive examples to help you run, modify, and experiment with the code during your live session.
Below is an overview of each slide. You can find the corresponding code in this repo.
- Introduces constants (let) and variables (var), string interpolation, and basic printing.
- Demonstrates arithmetic operators and custom operator overloading.
- Covers string manipulations like uppercase/lowercase conversion, concatenation, and character counting.
- Explores arrays, dictionaries, and sets with operations like sorting, filtering, and union/intersection.
- Showcases conditionals, loops, and switch statements to manage execution flow.
- Covers function declarations, external parameter names, default parameters, variadic functions, and tuple returns.
- Demonstrates using closures with sorted, filter, map, and asynchronous callbacks with @Sendable annotations.
- Explains enums with raw values, associated values, and computed properties.
- Compares value types (structs) and reference types (classes) and demonstrates their behavior differences.
- Covers stored, computed properties and property observers (didSet).
- Demonstrates instance methods, as well as static methods.
- Explains read-only and read-write subscripts for custom data access.
- Shows class inheritance with method overriding.
- Demonstrates failable initializers and convenience initializers.
- Explains how deinitializers are used to clean up resources.
- Demonstrates safe access to nested optionals using optional chaining.
- Covers throwing and catching custom errors using do-try-catch blocks.
- Demonstrates async/await, running asynchronous tasks, and concurrent execution.
- Explains safe downcasting using as? and type checking with is.
- Shows how to organize code with nested enums, structs, and classes.
- Demonstrates extending built-in types with additional methods and computed properties.
- Covers defining protocols, providing default implementations, and conforming to protocols.
- Provides examples of generic functions and generic types.
- Demonstrates protocols with associated types to create flexible, type-safe interfaces.
- Explains opaque return types using the some keyword.
- Demonstrates ARC, strong/weak references, and how memory is managed.
- Covers access modifiers (public, internal, fileprivate, private) and encapsulation.
