Swift — Course #308 · Apple's Powerful Modern Language

Build Powerful Apps

with Swift 🦅

Swift is Apple's modern, safe, and blazingly fast programming language for iOS, macOS, watchOS, and tvOS. Designed to replace Objective-C, Swift features expressive syntax, protocol-oriented programming, and async/await concurrency. Master Swift to build native Apple platform apps and server-side applications with Vapor.

What You Master

The Complete Swift Skill Set

From Swift fundamentals and protocols to SwiftUI, async concurrency, and server-side Vapor development.

🦅

Protocol-Oriented Programming & Type System

Swift's most powerful paradigm is protocol-oriented programming (POP) — protocols with default implementations replace inheritance hierarchies. Master generics with associated types, where clauses, and type erasure (any, some). Use Swift Macros (Swift 5.9) to eliminate boilerplate. Combine ARC memory management, value types (structs), and reference types (classes) for efficient, safe code.

⚡

Swift Concurrency

async/await, structured concurrency with Task and TaskGroup, actors for data isolation, and async sequences for streaming data.

🔗

Combine & Reactive Swift

Reactive programming with Combine — Publishers, Subscribers, Operators, and integration with SwiftUI's @Published and @StateObject.

🌐

Server-Side Swift with Vapor

Build REST APIs and WebSocket servers with Vapor 4 — routing, middleware, Fluent ORM, and deploy to Linux/Heroku/AWS.
