An introduction to the Swift Programming Language:
Swift is a robust and intuitive programming language that gives developers the freedom and capabilities they need to create a new generation of cutting-edge apps.
Since its announcement by Tim Cook, CEO of Apple in 2014, it has captured a significant market that continues to grow as time passes. Indeed, the announcement of its release by Tim Cook, CEO at Apple Inc. was met with much fanfare.
Over the last few years, the Swift app development has seen growth in popularity, and this is undoubtedly great news for all those iOS app developers who are looking forward to using it for building apps for iPhone, iPad, watchOS, macOS, tvOS and Linux. Learning Swift 4 and iOS 11 would enable you to build better apps with fewer codes than ever before.
Advantages of Swift Programming Language:
If Swift is the future of iOS app development, why should we use this technology in app development over any other alternative? Below are the major benefits that Swift offer:
- Shortens development time
Swift is an exciting new programming language developed by Apple with a thing for speed and safety. For example, Swift doesn’t need semicolons at the end of every statement like C or Objective-C.
You tell Swift what you want it to execute using structured English, and it takes over from there. It’s fun to read and play with and calls on the support of modern technologies such as generics, null safety, and so on.
This language is going to save you a lot of time and effort, thanks to its safe and fast capabilities.
- Low Maintenance
Developing an application is not the end of the task. Many a time, developers have to update it and keep it bug-free all the time to deliver an engaging user experience.
With Objective C, developers had to maintain two codes to maintain the efficiency of the code. Therefore, they had to make changes in both (.m) and (.h) files every time they made changes in the development process.
However, Swift .m and .h files into a single (.swift) file.
- Optimal for safety
Swift is extremely safe, which means you don’t have to worry about any unsecured codes. Swift uses the latest programming conventions to help maintain watertight security on the apps we create.
It enables us to describe valuables as value types or optional types, which means we can classify whether the value exists or is null (nil).
- Open Source
Swift app development is open source! Swift was declared open-source by Apple in 2015. Apple invites everyone to contribute to Swift, and the language is now running on multiple platforms as well as servers.
As of December 3, 2015, before its official release, Apple reported over 100,000 apps submitted to their App Store that were written with Swift.
- Possibilities of Experimentation
Using powerful compiling tools and an interactive environment to create apps, Swift is able to effortlessly compile complex programs.
Swift is designed to provide developers with an interactive experience with the app during its creation. Playground mode lets you write small bits of useful code to see how it works without needing to build an app every time.
- Easier to Read
Highly expressive, Swift is easy to read and understand code. It minimises the possibility of error and crash, so your apps are more reliable.
And it is powerful enough to be used by professional developers while also being a great first programming language for those just getting started.
- Easy Maintenance
Swift is a language that’s designed to be fast across all the Apple devices. It’s also easy to maintain because it doesn’t have any of these dependencies.
- Designed for Safety
Swift is an excellent tool for safety and security in programming. It automatically eliminates unsafe code in real-time. Once you declare a variable, that variable cannot be changed, which helps to eliminate bugs and other errors.
Swift also helps prevent overflow errors when using arrays: the compiler checks for overflow errors and prevents any terrible crashes that may occur during program execution
