The Best iOS Development Companies With the Expertise in Objective-C and Swift

iOS, the second-most popular operating system developed by Apple exclusively for its hardware, has come a long way. It was born in the competition between Mac and iPod developers. The Mac team won. They created a solution that was convenient for third-party developers who were familiar with Objective-C, the language of the Mac, by simply transferring it to the mobile platform.


iOS is still actively developed today, and over the course of ten years, it has become one of the most feature-rich and well-supported platforms on the market.

Has Swift already overtaken Objective-C?

The primary programming languages used for developing iOS applications are Objective-C, a member of the C family, and Swift, a relatively new language developed by Apple.


Objective-C has been around for over thirty years, but its use exploded in the gold rush of apps when it became the main development language for Apple devices. According to Tiobe, in 2007 Objective-C was number 59 among all programming languages, but already by 2011 and 2012 it had managed the status of “language of the year.”


But while Objective-C was busy becoming the hottest language, Chris Lattner along with other programmers at Apple had started work on developing a new programming language, Swift. Swift drew on ideas from a great number of programming languages: Objective-C, Rust, Haskell, Ruby, Python, C#, and more.


When Swift was introduced at Apple’s Worldwide Developer Conference (WWDC) in 2014, everybody had expected Apple to announce some changes to Objective-C. Instead, Apple knocked everybody's socks off by introducing Swift, a language that replaced Objective-C as the main iOS coding language. However, Swift is capable of working alongside Objective-C with the Cocoa and Cocoa Touch frameworks.


Swift is the fastest-growing language according to GitHub.


Demand for Swift developers has increased 600 percent, making them the most-hired developers. It's no surprise that Swift developers earn about $100,000 per year and have the highest average salaries among developers in the US.

Who develops apps in both Objective-C and Swift?

The Apple App Store has gone from 800 apps the month of its launch in July 2008 to 2.2 million in January 2017. Given the increasing demand for mobile apps, thousands of mobile app development companies have been emerging every year. Today, there are close to 19 or 20 million developers, and this number is increasing at a good pace.


To make it easier for you to find a reliable contractor, we’ve listed twelve companies that are well-versed in developing iOS applications.

What are the advantages of Swift for iOS development?

Swift is compatible with Objective-C

Swift is fully compatible with Objective-C that it’s possible to use Objective-C classes in Swift and vice versa. That’s possible due to the use of Objective-C Runtime and almost identical internal structure of classes.

Swift has clear syntax

Swift’s syntax is simple, concise, and unambiguous. And it’s capable to undertake many complex concepts through standard language constructions.

Swift is safe

Static typing, the concept of optional types, lack of direct managing memory and pointers, emphasis on immunity and protocols allow Swift to be quite resistant to errors as well as easy to debug.

Swift is optimizable

Thanks to the static typing, rigidity and unambiguous behavior of the application in execution, there appears an opportunity for aggressive optimizations impossible in Objective-C.

Swift is open-source

Swift is greatly impacted by its huge and friendly developers community that’s maintaining and supporting the language day to day. Here comes as well incredible speed of language updates. Initially created for Apple platforms it’s slowly expanding to build on Linux.

Swift is interactive

Swift playgrounds like read-eval-print loop (REPL) visualize data and allow developers to quickly check and correct everything along with further development.

What are the advantages of Objective-C for iOS development?

Objective-C is compatible with C

Since Objective-C is a thin layer atop C and its superset as well, it becomes possible to compile any C program with an Objective-C compiler and to freely include C language code within an Objective-C class. Put it simply, any program written in C will be a program in Objective-C.

Objective-C supports object-oriented paradigms

A significant innovation according to the trends of that time was the addition of object-oriented paradigm which gives the ability to developers to create complex abstractions for large applications and re-use the code.

Objective-C is flexible

Dynamic typing and the mechanism for sending messages provide incredible flexibility for Objective-C. While running the application it’s possible to create new classes and types right, add methods to existing classes and send messages to interfaces that don’t yet exist.

Objective-C is efficient

There’s an Objective-C Runtime system written in C that provides all the above opportunities without consuming a huge amount of resources, unlike Java Virtual Machine. But there’s one aspect: Objective-C Runtime only works with macOS and iOS operating systems.

Objective-C has a rich ecosystem

Being one of the members of C programming language family, Objective-C inherits some of its predecessors’ achievements. For example, Objective-C can use existing C libraries and even C++ via Objective-C++ extension or through C mediation.

Objective-C is a runtime-oriented language

Unlike its relatives, C and C++ languages, Objective has an Objective-C Runtime that supports reflection. Reflection means that Objective-C runtime allows developers to analyze code instantly.

Objective-C offers effective memory management

Objective-C can deal with memory management directly or via Automatic Reference Counting (ARC) which is more efficient than for example Garbage Collection used in JVM.

iOS was developed on the basis of Darwin, an open source operating system released by Apple as well. macOS was created on the basis on Darvin, and tvOS and watchOS were created on the basis of iOS. That means that all Apple platforms have an approximately similar core that greatly facilitates the development within the Apple ecosystem and provides the ability to port applications from one platform to another with minimal effort. For example, it's not a problem to port the iOS application to macOS.
