Swift Is the Technology of the Future for iOS App Developers

Swift will be “the next big programming language,” according to Apple CEO Tim Cook, who also predicted that iOS app developers will exclusively be using Swift to create apps in 20 years. Swift was first introduced in 2014. 

Swift is now not only the success story Tim predicted it would be, but it also represents the wave of the future for iOS app developers. Since its launch, Swift has actually already dominated the market.

So if you’re an iPhone app developer and you still believe differently, we’ll prove you otherwise.

This blog will cover all you need to know about Swift and explain why it’s the best programming language for creating iOS applications.

An Introduction of Swift Technology

Programming language Swift was created by professional developers to be user-friendly for newcomers.

Because it’s simple to comprehend and code in, Swift is actually regarded as a programming language that is extremely similar to the English language.

In addition, you may create apps for all Apple gadgets using the intuitive and authoritative programming language known as Swift.

In essence, it was created and introduced to the market to replace Objective-C, which has been there since 1984.

Swift is also very easy to maintain since Xcode (IDE) detects code errors automatically. Open-source is Swift’s main advantage for iOS developers.

In addition, Swift is compatible with iPhones and iOS, iPads, MacBooks, Apple Watch, and Apple TV, so you can build apps for all Apple devices.

History of Swift

Before Apple’s 2014 Worldwide Developer Conference, Swift developers started working on it in 2010.

Swift’s features, such as reduced crashes and concise syntax, quickly caught on with indie developers and start-ups.

Swift was designed to be a clear, concise, powerful, easy-to-understand language. People, however, often see it as a natural evolution of Objective C.

  • Swift’s initial release, version 1.0, underwent a significant upgrade to Swift 2 at WWDC 2015.
  • On December 3, 2015, Swift’s upgraded version 2.2 was released as open-source software for Linux and Apple platforms under the Apache License 2.0.
  • The syntax of Swift 3.0, the third edition, saw a significant modification. In the first quarter of 2018, Swift outperformed Objective C in terms of popularity.
  • Swift later saw significant modifications in the Swift 4.0 version, where you can use the migration capability included in Xcode to update the code created with earlier versions of Swift.
  • Swift 5.6 was introduced in March 2022. Partial type annotations improve pointer interaction in Swift 5.6 by acting as cues to the type inference engine.

There is no question that Swift has quickly grown into becoming one of the most powerful and popular iOS programming languages today.

Let’s examine Swift’s key features and understand why it’s better than Objective C in every way, if you aren’t convinced.

Swift Application Development: Why Do It?

Assuring secure and safe coding is Swift’s future for iOS development. Assuring a secure and protected environment is created to create a stable solution; it terminates all risky code classes with ease. Developers choose this language for these reasons.

  • Rapid, secure, and dominant
  • Interactive and group playgrounds
  • utilizes the strength of open source
  • modern error handling models
  • It saves time because one code works on both iOS and Android platforms.
  • Issues with functionality that require a native app developer to fix necessitate additional charges.

Top Swift Programming Language Features

Open Source:

The website, which is dedicated to the open-source Swift community, developed Swift applications. Source code, a bug tracker, mailing lists, and standard development lists are used to create it.

Along with a specific Linux toolset that includes package management support, the LLDB debugger, and the REPL, also offers a Linux version of the programming language. You can create apps with Swift for iOS, OS X, tvOS, and watchOS. However, it can only be used on a Mac.

In other ways, Swift makes programming easier and safer while also accelerating the development of applications.

Development of Syntax

Swift’s new syntactic features allow you to create code that is more expressive. To make code more secure and readable, the SDKs have made use of new Objective-C features like null-ability and generics explanations.

Play areas that are interactive

Professional developers can benefit from Swift’s Playgrounds. Without needing to create a whole iPhone app, it enables programmers to test out new graphics or algorithm routines.

Inline code execution is another feature Apple has added to its playgrounds, which will assist programmers in writing algorithms or writing a large number of codes while receiving feedback as they go. The speed at which code can be created may ultimately increase thanks to this feedback loop.

Playgrounds can also have notes that employ bullet lists in addition to embedded photos and links.


Swift eliminates whole collections of harmful code. For instance, variables are always initialised before use and memory management is automatic. Integers are also checked for overflow.

Swift also has the advantage that its objects can never be zero, which means that if you write poor code, a compiler error will result. In other words, issues can be resolved while the code is being written, saving you time and money on resolving mistakes.

Finally, if a Negligible optional variable is used, it results in a runtime crash, which can be utilised to work around the defect or completely repair it in Swift code sooner.

Quick and effective

Swift has become much better because it abandoned old C conventions. It converts Swift code into efficient native code using the incredibly fast LLVM compiler.

Python has been significantly exceeded by Swift in terms of how quickly objects can be categorised. In reality, it gives programmers crucial object-oriented capabilities like classes, protocols, and generics, which in turn gives Cocoa and Cocoa Touch programmers the power and efficiency they require.

Interoperability of Objective-C

You can create a project that uses files written in either Objective-C or Swift due to Swift’s full interoperability with both languages. Apps with a multi-language codebase can be created.

Additionally, you may easily develop functionality to your app utilising Swift’s most recent features and then seamlessly integrate it back into your existing Objective-C codebase.

Swift Programming Language Advantages

Let’s explore some uses for the swift programming language.

It cuts down on development time

Experienced programmers value a programming language that is easy to read and understand. This is offered by Swift because of its clear syntax, which makes reading, writing, and editing much easier.

Additionally, fewer lines of code are needed to perform an option. This eliminates the need for legacy conversions, which is the reason. Experts concur that it resembles ordinary English quite closely, making the entire methodology seem more natural.

Because of the time and money savings, the process of developing an app is more enjoyable.

The “For-In” procedure using Swift is demonstrated in the sample simple syntax below. When working with uncertain statements in this programming language, there is no need to finish parenthesis with a semicolon. It is beneficial to eliminate many errors, particularly when utilizing Objective-C.

Swift needs less maintenance.

The journey doesn’t end after an app is created and released to users. To ensure that users may use it for as long as possible, you must continually update it.

If developers wished to increase the code’s efficiency when utilizing Objective C, they had to maintain two code files. Swift, however, makes it obsolete by combining (.m) and (h) files into a single (.swift) file.

It’s Designed for Safety

Anyone looking to develop an app is most concerned with safety. The greatest benefit of using Swift is that you won’t have to deal with any dangerous coding.

It also makes advantage of the most recent programming standards to assist developers in maintaining the tight security of the programmers they create.

It should be noted that the programming language allows one to refer to valuables as optional or value types. It suggests that a skilled developer has the discretion to determine if a value is present or null (nil).

This means that the programming language will cause a runtime crash if a developer inadvertently selects the NIL optional value. As long as this is on the line of code, it forces the developer to fix any issues straight away.

In other words, Swift gives you no opportunities to create applications with hazardous defects or exception-free code.

Open Source

Apple proclaimed the programming language to be Open Source in 2015.

Many developers applauded the decision because it means Swift can be utilized for backend infrastructure and various platforms.

It is one of the main causes why so many developers favor it over other programming languages that are accessible.

In fact, it is safe to say that Swift’s development and uptake were significantly influenced by Apple’s choice. Swift is currently regarded as one of the best programming languages in the world.

And given the current course of events, it will shortly take the top spot and hold it for a while.

Explore Your Options

Swift includes a playground mode that users can use to practice specific application ideas.

It makes things lot simpler because it provides a realistic impression of how the app will turn out, allowing you to decide whether to move forward or focus on a more useful project.

The programming language’s support for dynamic libraries must be included.

These refer to downloadable chunks of code that programmers attach to an application. Simply said, it enables present Swift apps to communicate with newer iterations of the language as it develops over time.

Objective C vs. Swift: 4 Reasons Why Swift is the Future?

Swift is the future for creators of iOS apps, according to the reason listed below? We’ll see:

It’s simpler to read Swift.

Swift code and other contemporary widely used programming languages are strikingly close to spoken English. This makes it more straightforward for current JavaScript, Java, C++, C#, and Python developers to implement Swift into their tool chain.

Swift is simpler to maintain abreast with.

It can be challenging to confirm that your application is compatible with the platform due to the wide variety of device screen sizes and resolutions. Additionally, this helps users who are still using earlier operating system versions avoid or reduce issues and crashes.

According to statistics, Apple consumers are more inclined to update their operating systems than Android users, who tend to take longer to accept new operating systems.

Swift is safer

The processing of pointers in Objective-C, particularly nil (null) pointers, is an intriguing feature. If you try to call a method in Objective-C with a nil pointer variable, nothing happens (uninitialized).

Although it might appear advantageous that it doesn’t crash, the expression or line of code becomes a no-operation (no-op), which has been a major source of errors. The nemesis of programmers attempting to identify and correct a random crash or halt unusual behavior is a no-op because it causes unpredictable behavior.

Swift needs less coding.

Swift reduces the amount of code needed to create repeating statements and to manipulate strings.

When combining two pieces of information using text strings, Objective-C requires much too many steps.

Modern programming language features like combining two strings together with the “+” operator, which were sorely lacking in Objective-C, are now implemented in Swift.

For any programming language that shows text to a user on a screen, support for connecting characters and strings in this manner is essential.
