So, what actually is the iOS system about? iOS serves as an operating system for most of the Apple hardware devices, which are written with Swift programming language.

Here are more major reasons of why learning iOS development is important :
  • Discovering, evaluating, implementing tech approaches by pushing efficiency to the maximum;
  • Automatization and providing support to code quality;
  • Fixing traffic jams and bugs;
  • Processing new features in collaboration with cross-functional working groups;
  • Designing advanced native iOS applications;
  • Writing unit-test code for stability;
  • Working with edge cases in order to improve usability and reliability;
  • Building multi-threaded applications.

After learning and mastering your Swift coding skills you can become an iOS developer and join ranks of professionals. You’ll take advantage of developing iOS platforms used by hundreds of millions of people worldwide. Not only that, with the iOS system you will be building extensive APIs, libraries for development upgrades, utilizing Xcode tools, and more.

Few facts about Swift programming language

Developed by Apple Inc., Swift was issued back in the days during 2014. Swift was designated as an “official” language of iOS. Swift codes are also used on such mobile platforms, like iPadOS, macOS, watchOS, tvOS, Linux, or z/OS. Describing Swift language in a few words – as elegant as Perl, as powerful as C++.

Compared to its predecessor Objective-C, Swift language syntax was simplified. At the same time, more attention was paid to security protocols. Now Swift codes are much faster and much more adaptable to updates. Because of all these reasons, Swift is a top pick whenever one has to choose between Objective-C or Swift.

“It was the best that happened to Swift since Swift”

In 2019, Apple released a new updated version of Swift programming language –  SwiftUI. This version is an even more innovative and simple tool for creating user interfaces on Apple platforms. Some iOS developers say – it was the best that happened to Swift since Swift.

Some steps to become an iOS developer with Swift  

There is one way to code with Swift and become an iOS developer – going with Xcode on Mac. You’ll need a MacBook to install Xcode. You can also download macOS directly to your PC. There is also an option to find Xcode on the App Store or install it via developer.apple.com. An alternative option that can make learning Swift language fun and playful is to find it on the Swift Playgrounds (an application designed for iPad).

Once you have Xcode installed, go ahead and try writing Swift codes for building your entire iOS application. That way you’ll get your hands-on experience and learn Swift programming by practicing. Or try some practical examples to get your bearings in learning Swift. If your previous experience involved working with Objective-C only, don’t worry, this language is still fully supported. Your skills won’t go to waste along the way of becoming a skilled iOS developer. You can even mix and match them in your iOS projects. These two programming languages coexist with no problem. Any Swift files you’ve created for your target will be shown in the Objective-C files too.

However, you need to keep in mind that Swift language still exists in beta, which means – it’s subject to change. A good idea would be to follow all new updates while learning and practicing Swift. Keep an eye on new information like Apple news, notifications, and announcements and stay up-to-date with changes.
