AR Application

How effective is Swift’s AR technology in developing immersive applications?

Introduction:

Since time immemorial, humans have been imaginative and have always envisioned new concepts, such as superheroes or aliens. However, the most recent obsession among innovators is immersive technology, i.e., integration of virtual content with the physical environment, with about 6.3 billion dollars in revenue generated in 2020. This is evident from the popularity of Nintendo’s Pokémon Go game and IKEA Place.

Escalated by the post-pandemic environment, rapid digitalization and increased reliance on smart devices have led businesses to look for ways to cater to people using immersive applications. Immersive applications improve processes by bringing digital elements for better visualization, increasing user experience that translates to profitability.

Immersive applications actualize distinct experiences by integrating the physical world with a simulated reality. These technologies allow humans to have new experiences by enhancing, extending, or creating a mixed reality.

Among the different types of immersive technology are Augmented Reality (AR), 360, Extended Reality (XR), Mixed Reality (MR), and Virtual Reality (VR). The augmented and virtual reality market will surge into the market size of 160-billion-dollars by 2023, according to Statista’s forecast. Consumers’ attraction to immersive applications is visible by the increasing market size encouraging developers to offer relevant solutions.

Developers can create AR application for Apple products using various tools, frameworks, and languages including, but not limited to Xcode, ARKit, RealityKit, Swift, and AR creation tools.

This article involves understanding the efficacy of Swift in AR technology for developing immersive applications for business initiatives. Prior to that, it is crucial to comprehend AR and its effect on immersive applications.

Augmented Reality Apps and Its Applications

AR works by layering a digital layer on top of the real world and enhancing the user experience. The digital layer or augmentation consists of information or content consisting of videos, images, and 3D objects, providing a naturally semi-immersive and visual experience for user interaction.

AR has unlimited scope for innovation due to its non-restrictiveness of user vision, cost-effectiveness, and high engagement. Mobile AR users are expected to surge from 200 million in 2015 to 1.7 billion worldwide by 2024.

AR Application across industry verticals:

Apps use augmented reality to bring products to life by using 360-degree views either with headsets or through smartphone cameras.

  • Automotive Industry is using AR for designing, testing, and sale of vehicles saving much money and improving products simultaneously, e.g., Jaguar Land Rover, BMW Virtual Viewer, Hyundai AR Lens for Kona.

  • AR has provided significant benefits in the defense sector too by offering AR-simulations of machines allowing safe and easy assimilation of information regarding the work environment and equipment.

Swift and AR Technology

Apple has introduced a comprehensive set of tools and technologies for creating amazing AR application as mentioned below:

Swift is an open-source general-purpose compiled programming language developed by Apple for its app development.

Xcode is an integrated development environment for iOS and Mac. It has all the tools needed to develop an application, including a compiler, a text editor, and a build system in one software package. Xcode uses the Swift programming language to deliver an assortment of AR templates to create AR application rapidly.

ARKit is a framework for developers that allow designing augmented reality apps for iOS devices, such as the iPad and iPhone. It helps to device AR experiences quickly using the camera, motion sensors, and processors of the iOS devices.

ARKit Features:

ARKit empowers the developers to construct AR features for apps regardless of their previous experience. It offers multiple features to benefit the users and developers alike.

  • Location Anchor: This allows the anchoring of AR creations to specific geographical locations and offers various angles for viewing.
  • Motion Capture: Intensifies AR experience using one camera to record the real-time motion.
  • Enhanced Face Tracking: Amplifies AR experience for users with a front-facing camera.
  • Scene Geometry: Prepares a topological map with labeled objects of any space.
  • People Occlusion: Enables realistic responses of AR creations in the presence of obstacles such as persons and green screen effects in all environments.
  • Depth API: Adds precision and occlusion to the AR object, increasing the user’s immersive experience.
  • Instant AR: This helps in immediate AR deployment in the real environment.
  • Simultaneous Camera Usage: Maximizes AR object performance and delivery by utilizing both the front and back camera for a new experience.

Apple’s AR Creation tools consist of a reality converter and reality composer. Reality Converter offers the display, customization, and conversion of 3D models to USDZ to integrate them effortlessly to Apple tools and AR-enabled devices. In addition, Reality Composer facilitates the construction, assessment, refinement, and simulation of AR experiences using an intuitive interface.

The creation tool offers the following advantages:

  • Powerful built-in AR library to create any virtual object or use USDZ files to continue working on a previous project.
  • Incorporates dynamism into the AR using animations and audio for adding little details like movement, vibrations, and more.
  • Record and play feature offers specific information capturing using camera and in-built sensors in predetermined locations.
  • Delivers smooth transition between all Apple platforms and devices.
  • Supports export to USDZ, including all components authored in Reality Composer.

Benefits of Swift for creating AR applications:

Xcode powered by Swift, plays a leading role in bringing AR to users with a short turnaround time. The following merits make Swift the favored choice by businesses.

1. Accelerated Development:

Swift has a low code requirement due to its simple syntax. In comparison to Objective-C, it is easier to read and write. With built-in concurrency support and reduced code size, there is faster coding, resulting in fewer problems and easy maintenance.

According to Apple Inc., a Swift application is up to 2.6 times faster than Objective-C and 8.4 times faster than Python. Swift’s LLVM, a compiler framework that enables speedier code processing, further optimizes this speed for better performance. All these qualities contribute to the faster development of AR applications.

2. Scalability:

The AR apps created with Swift are highly scalable, i.e., the apps can be updated with new features as and when needed without any worries resulting in future-proofing. The elementary readability and simple syntax combined with effortless onboarding for new developers to the team makes it a preferred choice.

3. Security:

Swift provides robust protection with its error control and typing system to avert code crashes. Hence, with a concise feedback loop, developers can promptly find and fix the code’s errors. This removes the risk of time and effort wastage due to bug fixing.

4. Interoperability with Objective-C:

With the excellent benefit of interoperability with Objective-C, Swift language provides the unique advantage of fluid cooperation for AR app extension or updates. Above all, more features are added quickly, and the risks associated with porting are prevented.

5. Memory Management:

With in-built memory management and tracking performed by Automatic Reference Counting (ARC), developers do not need to be bothered about conscious memory management. In other words, ARC also enhances the app’s performance and does not affect the CPU or memory.

Combined with Swift’s in-built dynamic libraries, it reduces the app size and memory footprint, eliminating the need to constantly oversee and retain every class count. For instance, Swift 5 introduced an Application Binary Interface that decreases the bundle size and increases version compatibility yielding a much more stable application.

6. Cross-device support:

Using Swift in both the backend and front-end of AR application development supercharges the development process by enabling extensive code sharing and reuse. This allows cross-device support across all Apple platforms, including iPhone, iPad, MacBook, Apple Watch, and Apple TV and Linux platforms.

Final Thoughts:

Swift has tremendous potential to transform businesses by revolutionizing user lifestyles through engaging and riveting AR experiences. The above benefits highlight how Swift empowers the developers to create stable, secure, and high-performance AR application.

With the demonstrated success of various AR games, creative design solutions, and e-commerce apps, Swift is the first choice for any custom AR application development for Apple products.

VoIP Call Image

CallKit integration for VoIP Apps

Most of us by now are accustomed to using the services of a third-party provider to make VoIP calls over desktops, laptops, and smartphones. But making VoIP over Native iOS apps was never a convenient task. In fact, Apple has completely restricted the use of VoIP push for any kind of background processing from iOS-13. Earlier developers were using VoIP push for making call (audio/video) notifications or some other processing in the background. Apple took this decision to avoid the overbearing process that was happening in the background. It was not only leading to disproportionately high consumption of resources but also a significant drain of battery capacity.

A typical VoIP call usually comes as a notification on one’s screen, and in order to receive it, the user needs to slide the notification and also type a passcode to receive, if locked. Burdensome! Isn’t it? Especially if compared to how a native app eases the same experience.

The solution to this comes with CallKit, which is a framework that is capable of elevating your third-party VoIP app experience to a very intuitive one. You get the same rich, full-screen native call UI to accept and attend the calls. Once a call is accepted you also get a “Callback “option to initiate the same function (WebRTC) which you have used earlier. You can also set custom ringtones for your app that would be different from native call ringtones.

Besides, if you are on a call in your app and you start getting native calls, you will be able to hold and swap the calls. It could be an audio call, facetime call, or even another VoIP call. Even your call history will be stored in the call directory (missed, received, dialed calls, and add-in favorites). You can also make the call from Siri, Bluetooth, and access the “Do not disturb” functionality.

Swift 5 Vs ObjC

Is Swift the Objective Choice now?

‘Swift Vs Objective-C’– It is one of the first Google searches every iOS developer does before beginning their journey into the world of app development. At a broader level, choosing between Objective-C and Swift is also one of the fundamental and crucial decisions every business makes before beginning any iOS app development work.

So if the question is Swift or Objective-C? The answer cannot be in binary. If you have an existing application already written in Objective-C, then you can weigh the benefits of switching over to Swift vs sticking to Objective-C. However, if you are planning a new app, then Swift should be your default choice.

Why so? Well, read on to know…

……………………………………………………………………………………………………

The Story so far

Apple launched a new programming language called Swift in WWDC in October 2014. It came as a surprise to every developer as it was intended to replace Objective-C as the main programming language on Apple’s platforms, which by all means was stable, proven and had been around for more than two decades, powering millions of apps.

The goal was far-sighted. Swift was designed to be safer, faster, and easier to maintain. Though initially built for Apple platforms, it was aimed to be able to support all platforms. Before becoming Open Source, Swift was designed ground up by Apple using decades of Objective-C experience adding a modern touch derived from the latest programming trends and good practices. It was designed to have all the goodness of a modern-day programming language. Though a descendant of Objective-C, it is fundamentally different in terms of design, syntax, programming style and memory management.

But replacing a decades’ long programming language with a new one cannot be an overnight affair. There were thousands of libraries and hundreds of frameworks already written and working with Objective-C, as they were supposed to. Rewriting them using an infant language did not seem logical. Thus, Objective-C runtime continues to access Apple platform frameworks like UIKit, WatchKit, and AppKit. And Swift has the capability to interface seamlessly and work on top of it.

From the very beginning, Swift is fully compatible with Objective-C, as it should be. Both languages can still co-exist on all Apple platforms. And Apple isn’t likely to change this in the foreseeable future unless it has any strong reason to do that.

Support for interactive programming using Playground enables developers to test their idea live without building and running applications.

In terms of programming capabilities and flexibility, Swift has a lot to offer. Its functional programming style, and strongly typed language makes it impossible to have run time crashes resulting from out-of-bound or type-related issues. It has features like closures, tuples, generics, Structs and enums supporting methods, extensions and protocols, computed properties, powerful extensions, and the list just goes on…

Design-wise factors such as safety, readability, code size, less error-prone, efficient and fast iteration over collections, and other platform support make Swift fundamentally better than Objective-C.

……………………………………………………………………………………………………

Why Objective-C then?

Despite being so much powerful, Swift lacked just one thing that triggered Swift vs Objective-C debate, and that is ‘Maturity’. In the earlier years, deciding between Swift and Objective-C was like choosing between a fledgling with a lot of promise and a veteran with proven credentials.

Those who had rushed to develop production apps using Swift version 1 & 2, had to refactor the whole codebase, or just rewrite it again. It wasn’t matured, evolving rapidly, and syntaxes were completely changing in the early iterations. Hence, it was difficult to maintain Swift Apps compared to Objective-C, which was matured, trusted and possessed a huge developer base.

However, after Swift3, syntaxes became relatively stable and some minor refactoring that was needed was taken care of by the Xcode itself. And then Swift4 seemed to be more stable in terms of design and syntaxes, but, it still lacked ABI stability. Then came Swift 5.

 ……………………………………………………………………………………………………

What makes Swift 5 different?

So far, every version of Swift has been better than earlier. But what makes Swift5 so special is ABI stability.

Starting with version 4.2, Swift codes from one version have been compatible with another. However, the application binary, which can be considered as the machine level code for the sake of this argument, wasn’t compatible with that from a different version of Swift. That is, Swift wasn’t ABI stable until recently before version 5 was launched.

With Swift now being ABI stable for all Apple platforms like iOS, WatchOS, macOS and tvOS, all future versions of Swift including Swift5 will be compatible with each other at the binary level. True that Swift will continue to evolve in future releases, but the application written in the current version of Swift will no longer need to be refactored or rewritten to be able to support future versions of OS. In fact, libraries written now will seamlessly coexist and communicate at the binary level with code written in future versions of Swift and vice versa. And the reduction in app size is the immediate benefit it provides to the users now.

……………………………………………………………………………………………………

Conclusion

True Objective-C is here to stay. There are millions of applications already running using this. But, it isn’t getting any major updates, most of the updates are just to make it compatible with Swift. As a language, Swift is way superior. And above all, developers with expertise in Objective-C and practicing it will dwindle in years to come.
