Objective-C vs Swift: A Detailed Comparison for Aspiring iOS Developers

objective-c vs swift

Are you an aspiring iOS developer wondering which programming language to choose – Objective-C or Swift? Well, you’ve come to the right place! In this comprehensive blog post, we’ll dive deep into the world of iOS app development, exploring the key differences between these two powerful languages.

Objective-C Overview

Objective-C is among the oldest programming languages, developed at the beginning of the 1980s. Stepstone first created it as an extension of the programming language C; in fact, it added principles of object-oriented programming, initially taken from Smalltalk. Over many years, Objective-C has served as the mainstream language for writing iOS applications and macOS applications.

This is one of the main reasons to use Objective-C — among all other programming languages: it is fully interoperable with the large ecosystem of C and C++ libraries and frameworks. In this way, an Objective-C developer can leverage almost all code and tools already available, making the language quite versatile when developing iOS apps. Besides, Objective-C has an established, mature community with a vast resource and support base for developers.

However, the syntax of Objective-C can also be complicated for a first-year student. It is a nightmare dealing with manual memory management for some developers using Objective-C. Nevertheless, Objective-C remains in use for iOS development, especially in huge codebases already developed or where there is interoperation with C and C++ libraries.

Swift Overview

In 2014, Apple came up with a new programming language called Swift that was modern, safe, and expressive to replace Objective-C in iOS app development. Swift aims at more concise, readable syntax while improving performance and safety features for developers.

Swift’s clean, easy syntax is one of its significant benefits. This means that the language itself is more readable, with a syntactic style closer to natural English, which allows new developers to pick it up easily. Swift enables auto memory management; hence, no memory management is required, unlike in Objective-C.

Moreover, Swift is developed to be fast and responsive; performance optimization is present at the core of the language. The language features—like type inference and expressive functional programming—make it speedy and avert the developer’s productivity.

Although Swift was a relatively young language, it quickly gained favor with iOS developers. Several new iOS apps are now developing using Swift, and adoption is growing fast for the language.

Objective-C Overview

Objective-C, a powerful language based on C, dominated iOS development for many years. Let’s take a closer look at its history, key features, and how it holds a place in iOS app development.
