Swift – Programming Language

For Developing an iOS application, ios developers are using Objective-C language but in present iOS developers also choose a new option Swift 4 Programming language.

What is Swift?

Apple says: “Swift is a new programming language for iOS and OS X apps that build on the best of C and Objective-C, without the constraints of C compatibility. Swift adopts safe programming patterns and adds modern features to make programming easier, more flexible, and more fun. Swift’s clean slate, backed by the mature and much-loved Cocoa and Cocoa Touch frameworks, is an opportunity to reimagine how software development works.”

With plans to slowly retire the long-used Objective-C, Apple has introduced a new programming language, called Swift, for designing apps and applications to run on Apple iOS devices and Apple Macintosh computers.

Why Swift?

• Beginner Friendliness
• Easy to Understand
• Easy to Maintain
• Fast
• Optimized Memory Usage

Community

First of all, community size is important, because the larger a programming language community is, the more support you’d be likely to get. As you step into the programming world, you’ll soon understand how vital support is, as the developer community is all about giving and receiving help. Moreover, the larger a community, the more people will be building useful tools to make development in that particular language easier. As of now, there are over 600 notable programming languages worldwide.

So, with that context in mind, let’s get into the details of the Swift community size.

10th Most-followed Programming Language on StackOverflow

StackOverflow is a programming Q&A site you will no doubt become intimate with as a coding beginner. There are over 15k StackOverflow users following Swift, and over 69k Swift-related questions have been asked.

Fast-growing Meetup Community

At meetups, you can generally network and learn from fellow developers. Meetups often offer mentorship to those who want it as well. While Swift itself does not have as many Meetup members or groups compared to other programming languages, iOS Development as a whole has a ton of meetups, easily making it the second largest dev community on Meetup.com.

Furthermore, Meetup.com has over 110 Swift groups totaling over 40k members worldwide. Considering Swift is a rather new language, these numbers are already quite impressive.

What does it look like?

Basic Programming in Swift

/* My first program in Swift 4 */
var custString = "Hello, Weblizar!"

print(custString)

Output

Hello, Weblizar!

Future

The future of Swift mostly depends on the future of Apple, which so far seems very bright. Since Apple will be focused on improving Swift in the years to come, you can expect it to stay relevant for a good while.
