Advantages and Disadvantages of Swift

Swift is a high-level programming language developed by Apple Inc. for iOS apps, macOS apps, watchOS apps, and tvOS apps. It is the result of the latest research on programming languages and software design patterns, using a modern approach to safety. Since its 2014 release, developers have grown to love it for its modern features, easy-to-understand syntax, and compatibility with Objective C.

Because Swift is a multi-paradigm language, it supports a variety of programming approaches, including procedural, functional, and object-oriented programming. This makes Swift appropriate for a variety of projects, including desktop applications, web applications, and mobile games. It has a lot of advantages and disadvantages that will be explained in the article. 

How Is It Advantageous?

Swift is highly secure, with features like type safety and memory management. It is also optimised for multithreading, making it a great choice for real-time applications. Additionally, it is open source, which means that it is constantly evolving and improving. Some other benefits of Swift that you should be aware of before learning or using it are as follows.  

  • Compatibility With Objective-C
  • Security
  • Faster Development Process
  • Automatic Memory Management Using ARC
  • Reduced Memory Footprint
  • Scale Your Staff and Product With Ease

1. Compatibility With Objective-C

Developers can use Swift and Objective-C in the same project because the two languages are meant to work together. It is beneficial because it enables developers to reuse libraries and Objective-C code in Swift applications and vice versa. It makes the transition from Objective-C to Swift easier and less time-intensive.

2. Security

Swift is a speedy and efficient solution that offers excellent security as well. As a preventative measure, it removes entire classes of unsafe code, making it safer than C-based languages and enabling “cleaner” code with fewer runtime crashes. It features automatic memory management, initialization of variables before use, and overflow checking of arrays and integers. Additionally, code errors are readily visible to developers, reducing debugging time and eliminating the possibility of writing subpar code.

3. Faster Development Process

Swift is an easy-to-read and write programming language with clean and expressive syntax and grammar. It requires less code to achieve the same result than Objective-C because it is much shorter. Additionally, there is no need for semicolons in the code. Emojis and other languages are supported. Developers typically spend a significant amount of time and effort managing memory utilisation.

However, Automatic Reference Counting (ARC) automates tracking and regulating an application’s memory usage, saving developers time and effort. Thus, developing iOS apps with Swift typically takes less time. The language is also a value type, so it can be used for frequently used types like dictionaries and arrays without worrying about being updated elsewhere. This will speed up your development process.

4. Automatic Memory Management Using ARC

Swift leverages Automatic Reference Counting (ARC), a feature that introduces iOS’s first garbage collector. It automatically controls memory allocation and deallocation. Languages like Go, C#, and Java use garbage collectors to eliminate unnecessary class instances. Although they can increase CPU usage by up to 20%, they are beneficial for reducing memory footprint. 

IOS developers had to manually manage memory and keep track of counts for every class before ARC. It was time-consuming and error-prone. When an instance is no longer needed, Swift’s ARC recognises it and removes it on your behalf. It enables you to increase your program’s performance without resulting in memory leaks and crashes caused by memory-related problems.

5. Reduced Memory Footprint

When developing an app, you use a lot of third-party code. There are shared (or available) static and dynamic libraries. Static libraries, which become a part of your executable file during compilation and increase its size and loading time, are, as you might expect, locked into the code at that point. They are locked at the version you compiled, so they cannot be automatically updated.

  • While dynamic libraries only require one copy in your program’s files, static libraries require copies in every file. 
  • Conversely, dynamic libraries load only when necessary and exist outside of your code. It can be updated independently of the applications that use it. 
  • This allows developers to update a library with new features or bug fixes without updating all the apps that rely on it. 
  • Swift first made dynamic libraries available with the iOS release, significantly reducing the memory footprint.

6. Scale Your Staff and Product With Ease

With Swift, you can develop a product with many extra features that will stand the test of time. Swift projects scale much more efficiently, as you will find out. With Swift, you could expand and add more programmers to your development team or company. With a simple and clear codebase, onboarding is made easy. The language is extremely easy to read and uses natural language.

Disadvantages You Should Know About

Now that you know the advantages of the languages, it is critical to know its disadvantages too. The following are some of them for your information.

  • Relatively Young Language
  • Limited Third-Party Libraries
  • Version Compatibility Problems
  • Limited Cross-Platform Support
  • Inability to Support Previous Versions of iOS

1. Relatively Young Language

Swift was released in 2014 and may not be as developed or supported as older languages like Objective-C. The users will need additional resources to use the language. Many seasoned programmers accustomed to more traditional programming languages like Objective-C may have a bit of a learning curve. 

Working with older versions is also difficult because Swift is limited to supporting iOS 7 and macOS 10.9 or higher. With many recent releases, it is eventually making significant steps towards becoming a more mature language.

2. Limited Third-Party Libraries

Unlike other high-level programming languages like Java or Python, Swift is a relatively new and less popular language. It comes with fewer third-party frameworks and libraries, which could complicate development. Also, the language needs better interoperability with third-party tools and IDEs. Finding the right tools to help with particular tasks can be challenging due to the frequent changes. However, as the language gains traction and more developers and companies adopt the language, this is starting to change.

3. Version Compatibility Problems

The language’s recent versions have seen frequent language changes, which makes it vulnerable to version compatibility issues. Upgrading to a more recent version of Swift may present significant challenges, such as the requirement to redo the project’s code for the developer completely. Swift developers developed the Swift Conversion Tool for XCode to address this problem and significantly streamline code transfer between versions.

4. Limited Cross-Platform Support

As previously stated, Swift is compatible with Linux, Windows, and all Apple platforms. However, React Native, Xamarin, and Flutter dominate the cross-platform market because they were built and are still optimised for native iOS development. As a result, the language’s cross-platform support could be improved.

5. Inability to Support Previous Versions of iOS

Swift is limited to use with apps designed for iOS 7 or later. However, it is incompatible with legacy programmes that are still running on earlier operating systems. Although only a few Apple devices are still running iOS 6 or earlier versions, it is something to be aware of.

These are the major advantages and disadvantages of Swift. Even though it is a relatively younger language, its popularity is rising so the need for qualified Swift developers has increased. Companies are frequently taking advantage of the language by hiring developers who can get around the platform’s complexities quickly and use its features to create reliable applications. It has helped many businesses stay ahead in the cutthroat digital landscape. Hope this article will help you out too.
