Swift is a programming language for iOS, macOS, iPadOS, watchOS, tvOS, and Linux applications. Apple introduced it in 2014, and since the release, it gradually becomes the most popular technology for iOS mobile apps. Swift became an open-source programming language at the end of 2015. Right now, we have almost 800 contributors that are actively improving the language. The latest version of Swift brings a wide number of changes and new features for iOS app developers. In the 1st quarter of 2020, users were able to choose between almost 1.85 million available apps for iOS.
Why is it worth to code a mobile app in Swift programming language?
If you are thinking about developing an iOS application, you need to know that Apple is selective and restrictive when it comes to publishing mobile apps on the App Store. That means you have to choose the technology that is widely supported by this influential company. There are 2 most important technologies for iOS development: Swift and Objective-C. The core of Swift is similar to Objective-C, but it provides many essential features that we won't find in Objective-C. Since the day of release, Swift grew really fast and became one of the most popular programming languages in history. Right now, Swift positions on the second place on a list of programming languages that are actively developed on GitHub.
Last week Apple introduced the newest version of Swift 5.3. Over the last year, many improvements had been made in Swift. Comparing to the Objective-C, Swift 5.3 requires one and a half times less code size. According to StackOverflow surveys (from 3 last years), Swift consistently appears on a list of the most loved programming languages by developers. In fact, this programming language has many advantages (a list of benefits is at the end of the article). The latest WWDC does not include the topics about Objective-C. We can observe that Apple is paying tremendous attention to Swift.

What are the business benefits of Swift?
From the business point of view, clients usually consider a few factors while choosing the best technology for the project: the cost of software development, the speed of implementation, and the possibility of further innovation. Let's take a look at how Swift matches those criteria.
#1 Speedy App Development
Apple rightly positions Swift as a speedy and lightweight language. Our Developers confirm this assumption. Faster development saves money and allows creating a product that can be quickly updated, modified, or extended. It means that your Swift app will promptly respond to changing market environments, and it can have a significant impact on application success. Apps written in Swift are also easy to scale. That's why so many startups choose Swift 5 as the chief technology.
#2 Lower Cost of Maintenance
Swift is a compact programming language that requires less code than other mobile technologies. iOS developers can implement features and reduce the number of code lines. Less code means lower cost of the app maintenance. Lyft is a great example of an app that reduced the code and kept the same functionality. Through over the years, at the climactic moment, Lyft inflated to 75,000 lines of code. After implementing the Swift, they received a fully functional mobile application with less than a third of that.
#3 Higher level of security
Apple had designed Swift with the strong intention of improving the code safety for iOS products. That's why this programming language ensures a high level of security. Swift's syntax and code construction allow excluding many typical bugs delivered by Objective-C. How is it possible? Swift has a shorter feedback loop. Developers can see mistakes immediately and fix them instantly. The risk of providing a questionable quality product is much lower.
#4 Supported and accepted by Apple
Well, your iOS app has to appear in Apple's App Store, that's for sure. It is one of the first places where users are looking for mobile applications. As I mentioned before, Apple is rather demanding in that case. Following their best practices and trends will benefit your business. The technology used for your app needs to meet the Apple requirements and be 100% compatible with the iPhone system. Right now, Swift is the leading technology for iOS apps.
Now we want to share it with you!
What is the future of Swift?
We observe that Apple is creating their independent ecosystem. This open-source language attracts the attention of developers and software companies. Using Swift responds to The global job market shows that Swift Developers are in demand and well paid. Everything indicates that iOS development will be driven by Swift in the coming years. Is Swift better than other technologies?
How to successfully develop an iOS application written in Swift?
First of all, you need to choose a solid IT partner that has experience with coding in Swift. In that case, you can cooperate with a Selecting the software development company will deliver you extensive know-how and service, but you will have to pay more. Hiring a freelancer is a cheaper option, but there is a high chance that it wouldn't meet your expectations. Software house will that will work on your app success. To deliver an iOS app that will be well-designed, bug-free, and have a strong core, you'll need Developers, UX Designer, and Project Manager.
Every iOS app has to answer to market needs. It's essential to validate the app idea and check whether it will meet the user's interest. We recommend organizing (the initial stage of developing IT products).
With Swift, you can build apps for every Apple device: iPhone, iPod, iPad, Mac, Apple Watch or Apple TV. No doubt, this technology allows to release the full potential of iOS development. It gives you a broad spectrum of business and monetization opportunities.
“Everything’s going to revolve around Swift.”
Martin Conte Mac Donell, Principal Engineer at Lyft
As you can see, from the list above, great companies like LinkedIn or Mozilla Corporation had written their iOS apps in Swift 5. They know that proper code is imperative to maintain the application in a long-time perspective. If you are looking for a programming language that will allow your application to freely grow, Swift is the right choice. At Railwaymen, we honestly recommend it for our clients.
