Pros and Cons of Swift Programming Language

A big part of making a choice between programming languages is your team’s experience and preferences. If your developers are skilled at Objective-C, having them all migrate to Swift may not be an option. If you don’t have the luxury of postponing https://www.globalcloudteam.com/ your app release until members of your team get comfortable with Swift, you should consider sticking to ObjC. While the need to exclusively import C++ files is a rare case, you should be aware that Swift doesn’t have that supported.

However, the company is aware of these issues and with the Swift 5.0 they’re making the right changes. This latest version has a strong backward compatibility and you can now view and access all the changes that we’re done in the previous versions of Swift. Opposed to Objective-C which forces developers to take care of two code files, Swift stores all the header (.h) and implementation (.m) files in a single file (.swift). Ever since December 2015, Swift has been open-source and available to everyone. Developers of all skill levels can easily access knowledge bases created by the community, contribute to bug fixes, share their solutions, etc. For more information on how this works, check out Swift’s official community guidelines.

Swift first introduced dynamic libraries to iOS when it launched.Since the release version 5.0, standard Swift libraries are integrated into every macOS, iOS, tvOS, and watchOS release. That means any app built on those platforms will be smaller, because these libraries are included. With this advancement, stable application binary interface (ABI) was also released. That allows Apple to provide support of Swift across its platforms. With a focus on performance and speed, the language was initially designed to outperform its predecessor.

High-end open-source community with adequate resources

That’s also better than Objective-C, which is 2.8x faster than the Python version. After Swift’s big reveal, there was a lot of surprise and confusion in the development community as Apple claimed that this iOS coding language was to be better than its predecessor. For this reason, Swift has been the centre of discussion among many organizations.

It is also expected that the problems faced by developers today, would be addressed with time as newer versions of Swift Programming Language are released. The developers have raised this concern of lack of backward compatibility with each new release. After a new version is released, developers are sometimes forced to completely rewrite the project in order to stay up to date. Xcode has solved this problem to some extent by helping the people update their swift code however it doesn’t fix all the issues.

That means the code will be portable to all platforms that Swift supports. Swift takes the nil code, and generates compiler error when programmers write bad code. With Swift, you can compile, and fix the errors while writing the code, which is not possible with Objective-C. As a result, Swift works better and faster compared to Objective-C when it comes to bug testing.

Cross-device support

Consequently, upgrading to a more recent version of Swift might provide serious difficulties, such as the need to fully rewrite the developer’s project’s code. To solve this issue and substantially simplify code transfer from one version to another, Swift developers created the Swift Conversion Tool for XCode. Swift has a powerful Standard library of its own, which covers all the needed functionality for writing Swift apps.

  • This reduces the amount of code needed for development compared to Objective−C.
  • Within a short period of time since its launch, Swift has acquired the support of a large supportive community and a huge number of third-party tools.
  • Swift uses a solution called Automatic Reference Counting (ARC) that builds upon its ObjectiveC predecessor.
  • According to developers, Swift and Objective-C should learn to Coexist.

While programming languages for app development often come with complex and extensive command lines for intricate solutions, Swift stands out with its concise nature. This characteristic reduces the lines of code (LOC), enhancing programming efficiency and speed. The fact that in order to emerge as a defining programming language, the code and technology should be open source is acknowledged by Creators of Swift. Within a short period of time since its launch, Swift has acquired the support of a large supportive community and a huge number of third-party tools. Well, most programmers currently prefer to build an iOS app with Swift.

This can speed up your development process and reduce your overall development efforts. In Swift, ARC determines which class instances are no longer in use and gets rid of them automatically. Before ARC, developers had to manage memory manually and track reference counts for every class. ARC eliminates the need for developers to perform these tasks manually, which allows increased performance without lag in memory. This article will explain to you the advantages of using the Swift programming language. While Swift has been designed to make maintaining and writing app code easier for the developer, there are a few disadvantages to consider as well.

For example, the compiler will infer that ourVariable is an integer because its value is set to an integer. Our 1-week Educative Unlimited Trial allows you to get hands-on with Swift programming for free. Once you’re done, browse through hundreds of other curated courses to continue taking your programming skills to the next level.

With years of experience in the IT industry, she helps businesses harness the power of technology for growth and success. Leverage the influence of the modern language Swift, which stands for the best choice when it comes to building an iOS app, especially for enterprise solutions. No doubt there are some drawbacks too in Swift, but still, it is a fresh concept.

The initial claim of a 40 percent increase in speed over Objective-C has been proved to be true according to the benchmark tests conducted by individual developers. Another biggest strength of Swift is its safety, Strong typing and error handling functions prevent code crashes and errors. Developers can see errors in the code easily and they can fix them on the fly, reducing the efforts and time needed for bug fixing. Swift is a clean and expressive coding language that consists of simplified syntax that is easier to read and write. The ARC (Automatic Reference Counting) feature keeps an eye on managing the app’s memory usage. So programmers have to put less effort into executing such tasks manually.

Before the introduction of Swift’s ABI, it was not possible to create static libraries in Swift. While that’s now possible, there are issues implementing those dependencies into a project. Within a few years, the community has moved from the outdated Objective-C language to a modern, backward-compatible programming language that is easy to learn and read. For businesses seeking a programming language to develop an app, here are the pros and cons of Swift.

Swift projects are very easy to scale application because Swift is future-proof and you can extend the functionalities when new features are needed. Also, the fact that Apple is supporting Swift rather than Objective-C should also be considered when making an investment. To get started learning these concepts and more, check out Educative’s course Swift Programming for Mobile App Development. In this hands-on course, you’ll cover topics ranging from arrays, dictionaries, integers, object-oriented programming, error handling, and more. By the end, you’ll have the foundational knowledge you need to begin diving deeper into Apple-based app development. Overall, Swift is a more desirable language to choose because it’s safer, faster, more intuitive, and interactive.

Optionals are a programming concept that enables developers to prevent app crashes while ensuring clean code is maintained across the application. To know for sure, optionals need to be unwrapped, and if done properly, they won’t cause crashes. Swift is a clean and concise programming language that is growing fast and becoming increasingly popular. Swift was initially used for iOS development but has become very popular for many other things like macOS, watchOS, and server-side development. Despite its young age, Swift is becoming a widely used programming language for iOS development. A few of the companies that have already chosen Swift are Eventbrite, Kickstarter, LinkedIn, Twitter, and Whatsapp.
