[Objective-C] Study Resource Collections

Overview

A curated list of useful study resources for learning Objective-C.

Introduction

I compiled the Objective-C study resources that I used when I first started iOS development. As I reviewed these materials one by one, I realized that quite some time has passed since I intensively studied and used Objective-C, and some of the resources resonated with me again, so I should revisit some of them myself.

Since it can be tricky to separate Objective-C from Foundation, many study resources cover both topics together. Still, if you are studying both at the same time, it is a good idea to clearly understand the distinction between Objective-C and Foundation.

The Objective-C language itself does not support class-based string, number, collection data types, or network and OS services. Therefore, Apple provides a separate framework called Foundation that defines the fundamental layers needed for app development.

Objective-C != Foundation

If I get the chance later, I would also like to translate and organize the remaining resources that do not have copyright issues, excluding books.
