Things you need to know about Swift

What is swift? Swift is a general-purpose programming language. The popularity soars more when it comes to designing iOS related products. Apple has introduced the language specifically for Linux, and his other operating systems. Before this, Apple employed objective-C for mobile app design and development. Later, Swift emerged subsequently and changed everything. To clarify, running C, C++, and Objective-C at the same time has become possible.

In this article, we are going to look into the programming language called swift. What is Swift? What are Swift’s attributes? Its merits and demerits? What is swift’s framework? What is swift’s code? we’ll talk about this today. So, if you want to know more about this language, this article will do you good. Stay with us.

What is swift?

In 2007 when Apple introduced the first iPhone, (the A1203), the app development market was prospered for iOS apps. A programming language is an essential element in designing an app and having a successful development. A young language in the area is Swift. It is an object-oriented, multi-paradigm, compiled programming language. To solve problems, bugs, and issues of Objective-C, Chriss Latter put it on the market. Cocoa and Cocoa Touch are bridges for Swift to access Objective-C codes. In fact, the sole purpose of coding this language was solving bugs and minimizing codes, thanks to the Xcode compiler.

Swift1.0 was the first release by Apple. From then on, multiple updates have been made to be widely available. The ultimate version of Swift with Xcode6.0 was released on the 9th of September in 2014. Then, the 1.1 version with Xcode 6.1 was released on the 22nd of October. Swift1.2 was released on the 8th of April in 2015, alongside Xcode6.3, and Swift2.0 was released later in 2015. Furthermore, versions 4.0, 4.2, and 5 were introduced by Apple in later years. Apple released SwiftUI, a framework for designing user interfaces (UI) for all of Apple’s operating systems at the 2019 Worldwide Developers Conference (WWDC).

Many things have changed as a result of the updates. For instance,

  • Syntax alterations
  • Names of libraries and methods
  • New ML and AR Kit library Cores have been added
  • A new framework vision

What are Swift’s attributes?

1- Protocol-Oriented Programming Pattern

The protocol is actually similar to Class in object-oriented languages, but it outperforms them. Inheritance does not work well in object-oriented languages, but it is simple to do with protocols.

2- Code encryption and decryption

Since all applications rely on data transfer, data security is one of programmers’ top concerns to avoid being scammed. Applications communicate with a variety of networks and APIs, and the data they send and receive must be encrypted and then decrypted. Many features in Swift’s diverse language libraries ensure code security.

3- Having a selection of variable options

When a variable encounters nil and null errors, programmers place a question mark in the code structure to prevent the application from crashing.

4- Having an integrated software development environment called Xcode

Using an IDE developed by Apple called Xcode, programmers can fix problems and errors in Swifts’ language. In addition, the Xcode software supports all the sources of the coding languages C, C++, Python, Java, AppleScript, and Ruby languages.

So, until this point of the article, Swift is a perfect language for software development and construction for iOS. At Twelfth dream, we deploy Swift to design native app for iOS. Business is booming for Internet-based services. Invest in your idea, and you’ll Rise and shine. Teaming As A Service (TAAS) won’t let you fall behind competitors. Contact us to find out more.

Swift’s merits and demerits

Its merits

It has a brisk development pace

Swifts language is super-fast. It is not only easy to use in terms of syntax and grammar, but it is also very precise. In other words, running tasks necessitate a shorter code. To give you an example, Lyft is a good case. Apple has completely recoded it with Swift. The previous version of the app included 75000 lines of the code, and when recoded with Swift, the number was lowered to 25000.

The highly praised language benefits from Automatic Reference Counting (ARC). ACR takes care of the app’s storage for you. As a result, developers will be able to use more time and energy to focus on other aspects of the application.

It is supported by Apple

Apple adds useful features and tools to Swift more than it adds to Objective-C, which proves Swift is more important to apple than Objective-C.

It has reached high points in security and performance

Benchmark tests taken by engineers proved that Swift is 40% superior to Objective-C. Type-safeness prevents type errors, and the number of errors have lowered exponentially, which elevates Swifts security.

It is interoperable with Objective-C

When a big project is ahead of coders, the collaboration between these two will decrease the project’s risks of a bad outcome.

It is efficient memory management

Memory was managed by developers prior to the arrival of ACR. ARC identifies which class instances aren’t in use and removes them from developers’ workspaces.

Its demerits

It has a lack of IDE tools

As you know, one of Apple’s most popular IDEs is the Xcode software. Of course, this software has several issues (such as compilation bugs) that prevent it from providing comprehensive language support in Swift.

It doesn’t support iOS versions 7 and lower

Apple executives have stated that pre-iOS7 versions are not support by Swift, so it is not possible to use this language on 6% of Apple products (products that can’t be updated above iOS 7).

SwiftUI is an innovative and incredibly simple way to build user interfaces on all Apple operating systems. You can create user interfaces for each Apple device using just one set of tools and APIs. SwiftUI works seamlessly with the easy-to-read and easy-to-write Swift syntax with new Xcode design tools to keep your code and design perfectly in sync.

Coca Touch

Cocoa Touch is a UI framework for building software applications running on iOS, iPadOS, watchOS, and tvOS. It gives you an abstract layer on all apple devices except for devices that run with macOS. Cocoa Touch is based on the macOS Cocoa API toolkit and, like it, is primarily written in Objective-C. The framework lets you use hardware and features not found on devices that run with MacOS and is therefore unique to iOS devices. Just like Cocoa, Cocoa Touch follows the architecture of the Model-View-Controller software.

Swift’s code in a nutshell

In this section, we introduce two basic commands. For more information follow

The Println command is for printing strings and variables. Look at the code below

var name = “Amy”

var age = 10

println(“Meet (name). (name) is (age) years old”)

Putting comments is the same as other languages such as PHP.

A single line comment

// This is a single line comment

A multiple line comment

/* This is a comment

that spans

multiple lines */

The bottom line

Despite its youth, Swift is capable of a wide range of tasks in iOS development. Swift has been implemented by LinkedIn, WhatsApp, and Twitter. At Twelfthdream, we employ Swift for iOS development. TAAS customize software solutions fully optimized for you, and we use Agile Scrum as our tool to do this.

Twelfthdream is based in Vancouver, Canada. With Twelfthdream, a team is behind you to make your idea come true. We have exceeded all the expectations in our projects. Take a look out our portfolio here.

Frequently Asked Questions

What are nil and null errors? This error happens when you are handling a null value. A null value is empty. It is nothing.

How much does it cost to develop an app with Swift? iOS app development usually starts from $50000.

Is Swift case sensitive? Yes, it is a case sensitive language.
