Swift Tutorials – Learn Swift from Basics to Advanced

Swift is Apple's language for building iOS, macOS, and cross-platform apps. These guides focus on the parts that trip people up most: optionals, value vs reference types, protocols, properties, and SwiftUI's state management system. Each article explains one concept clearly, with practical examples you can apply straight away.

Optionals

Optionals are one of Swift's most distinctive features — and one of the first things new developers need to understand. These guides cover every way to safely (and unsafely) unwrap them.

• How to Use Nil Coalescing in Swift
• How to Force Unwrap in Swift
• How to Use Implicitly Unwrapped Optionals in Swift
• How to Use Guard vs If in Swift

Structs, Classes & Protocols

Swift leans heavily on value types and protocol-oriented design. These guides explain how structs and classes differ, when to choose each, and how protocols and extensions let you share behavior across types.

• How to Use Copy-on-Write in Swift
• How to Create a Protocol in Swift
• How to Use Protocol Extensions in Swift

Properties

Beyond basic stored properties, Swift gives you computed values, change observers, and lazy initialization. These guides cover when and how to use each.

• How to Use Property Observers in Swift
• How to Use Computed Properties in Swift
• How to Use Lazy Properties in Swift
