Swift is recognized as one of the most feature-rich programming languages for developing apps for iOS, macOS, watchOS, and tvOS. While Apple devices continue to gain popularity among users worldwide, iOS-based apps are becoming increasingly important. Multiple companies are looking for dependable Swift developers to meet the rising demand for these products. Is it possible, however, to hire competent and talented Swift developers with experience developing iOS apps?

Let’s dive into the popularity of Swift language and how to find an expert in this field.

What Is Swift?

Swift is a clean and concise language that is rapidly growing in popularity. Swift was originally designed for native iOS development, but programmers now use it to write safe and easy-to-use code for operating systems such as Windows and Linux.
Swift, an open-source programming language developed by Apple, was designed to be a replacement for all C-based languages, including Objective C, C++, and C. The language was created in 2014 and made available to the public as an open-source project on Swift.org in 2015.
Tiobe research shows us that Swift has risen to the 11th most popular language among programmers in its short time as a programming language. At the same time, the PYPL index emphasizes an even better result - Swift here in 8th place.

Swift features

  • 01.

    Powerful generics.

    Generics are powerful because they allow developers to write flexible, reusable functions and types that can work with any type.
  • 02.

    Native error handling.

    Swift provides the ability to throw, catch, and manipulate errors at runtime.
  • 03.

    Structs and classes.

    Swift allows you to define a structure or class in a single file and make the external interface available for use by other code.
  • 04.

    Protocol extensions.

    Swift enables you to define behavior on protocols rather than global functions or individual conformances.
  • 05.

    Memory safety.

    Swift manages memory automatically and prevents unsafe behavior in your code.
  • 06.

    Memory management.

    Swift tracks and manages our app's memory usage using Automatic Reference Counting (ARC). This means we don't have to worry about memory management.
  • 07.

    Flexible enumerations.

    Swift enums can have payloads and support pattern matching.
  • 08.

    Package manager.

    The Swift package manager is a cross-platform tool for building, running, testing, and packaging Swift libraries and executables.
  • 09.


    Swift employs the LLDB debugger, which includes a REPL and a debugger for integrated debugging, consistent formatting, failure recovery, and expression evaluation.
  • 10.

    Closure syntax.

    Swift has a lightweight closure syntax that has been optimized for clutter-free syntax and clarity.
As it already was mentioned before, Swift tends to replace Objective-C either but the last one is still used by other developers. So what are the differences between them? Let’s see:

Swift vs Objective-C

The Objective-C programming language is an object-oriented, general-purpose programming language. Prior to the introduction of Swift in 2014, it was the primary programming language used for OS X and iOS development. It combines C and Smalltalk features. Objective-use C's and popularity began to decline after the creation of Swift, though existing Objective-C apps will still need to be maintained.

What makes Swift the preferable alternative?

First and foremost, Swift is not the direct successor to Objective-C. Both languages have distinct capabilities that can be combined for mobile app development. Let us now compare the two languages side by side.


  • Swift allows you to develop in Xcode, Swift Playgrounds, Cocoa Touch, and other environments.
  • Swift is a modern, human-friendly language with a simple syntax, which means faster coding.
  • Swift, according to Apple, is 2.6 times faster than Objective-C.
  • Swift has extensive documentation that is constantly being updated.
  • The need for Swift developers is growing.


  • Objective-C is primarily used to develop apps in Xcode.
  • Because the language is less intuitive and human-friendly, using Objective-C typically results in slower coding speeds.
  • Objective-C is 2.6 times slower than Swift and requires more time to write due to its more complex syntax.
  • Objective-C has extensive documentation, but it is rarely updated.
  • Objective-C developers are in short supply.
Swift is a more desirable programming language to use because it is safer, faster, more intuitive, and interactive. Swift supports Objective-C interoperability, which means Swift code can coexist with existing Objective-C files. Swift also gives you full access to Objective-C APIs.

Key Advantages of using Swift for Business

Swift has a set of unique tools, allows for faster development, and has a high level of interactivity. As a result, it has become the preferred option for many business owners and iOS app developers. Let’s see why:
  • 01.

    It is still relatively new on the market

    Apple Inc. recently released Swift to the market. It debuted on June 2, 2014, but its official release date is April 21, 2017. (3.1 version). As a result, it is still new in comparison to Objective-C. Objective-C, on the other hand, was released around 33 years ago and was essentially a continuation of the C-language. Apple had to release it separately because it was not yet ready to support Objective-C functionalities.
  • 02.

    It’s open-source

    The Swift Development Language was developed in an open course, making it easier for users to upgrade all source codes, bug tracker, and email list at regular intervals. Because of its robustness, it is possible to read the technical documentation. This directly contributes to the development of future applications. Furthermore, it supports all Linux-based platforms.
  • 03.

    Comply with Data at a Much Faster Rate

    Compared to Objective-C, Swift is capable of managing data at a much faster rate. It has been using the LLVM compiler to generate optimized native code for operating systems. The developer is given the option of rewriting several groups as structures. In the case of Objective-C, there were only a few classes, which resulted in slower coding and, as a result, a longer time frame. Swift takes less time to code than other languages, as previously stated.
  • 04.

    The Right Language for Creating Business Apps

    Its efficiency has been demonstrated through numerous tests and other activities, and it is thus regarded as one of the best programming languages for developing business apps. The company (Apple) has on board the most skilled developers, who are constantly working to make it more user-friendly.
  • 05.

    Reduces Memory Usage

    Swift once again outperforms Objective-C in terms of memory consumption. The latter had an object-link and used some of the computer's RAM (Random Access Memory). Swift, on the other hand, was a single object-oriented program that switched to structures. The number of data types and SDK classes was also reduced, making memory more efficient.
  • 06.

    Not limited to use only for iOS Development Apps

    You might believe that because Swift was developed by Apple, it is suitable for developing iOS-based mobile apps. However, this is not the case. Though it has been adapted by Linux and other programs, it can also create useful and fully functional apps for Android.
  • 07.

    It takes less time to code

    When developing an app in Swift, you will most likely only need a few lines of code. As a result, not only is your job easier, but you can complete your code creation work in a shorter period of time.
  • 08.

    Safety Storage of Data.

    It has an integrated storage system for safe data storage. Apart from that, it is simple to understand if you want to become an iOS app developer, and any type of business, whether large or small, can benefit from it.
Although Swift is a relatively new programming language, it has already established a strong market presence and is thus competitive with other programming languages.
