🧩 Swift Basics: Closures

A concise, runnable Swift Playground exploring closures — from the simplest block to closures as function parameters.

📖 Overview

Closures are self-contained blocks of functionality that can be passed around and used in your Swift code — they capture references to constants and variables from the context in which they are defined and behave much like anonymous functions.

This is a small, runnable Swift Playground that demonstrates the core forms of a closure step by step: a bare closure, closures that take parameters, closures that return values, and closures passed into functions as arguments. It is meant as a concise learning reference you can open and run to see each concept print its result.

✨ What it covers

• Simple closures — defining and immediately calling a closure with no parameters.
• Parameterized closures — closures that accept one or more input parameters (String, Int).
• Returning closures — closures with explicit return types, including -> String and -> Bool.
• Closures as function parameters — passing closures into functions using both named and shorthand argument labels.
• Working with inout — using a closure's return value to mutate an inout parameter inside a function.

🚀 Getting Started

git clone https://github.com/ahmetbostanciklioglu/Closures.git
cd Closures
unzip Closures.playground.zip
open Closures.playground

Open Closures.playground in Xcode and run it to watch each closure example execute in the results sidebar.

📋 Requirements

• Xcode (with Swift Playground support)
• Swift 5
• iOS playground target
