In all of these years, iOS app development and Android app development have evolved in several ways. While each has its loyal users, both of them have been crushing the smartphone market. With the growing popularity of iOS smartphones and app users, corporations have been thinking and launching items on the iOS platform to maximize earnings.
If you decide to build your next iOS app, the key decision you'll make is which technology stack to use.
Whether to design a native app or a cross-platform app?
And if you go for Native app development then which language to choose?
To answer these, Swift has revolutionized the way iOS apps are created by making what was previously impossible feasible.
Swift is a popular, fast, and efficient programming language from Apple, featuring cutting-edge functions.
Learn why the Swift programming language is so important in native iOS app development. But first, let's know what native iOS app development is in brief.
What is Native app development?
The term "native app development" refers to the creation of a mobile app that is designed specifically for a single platform.
Native mobile apps, unlike websites and web applications, do not run in the browser. You'll have to get them from platform-specific app shops like Apple's App Store or Google Play.
For example, Apps for iOS are written in Swift or Objective-C, while apps for Android are written in Java.
What is Swift?
Swift is a programming language developed by Apple in 2014 to work across Apple's whole ecosystem- iOS, iPadOS, macOS, tvOS, watchOS, and Linux applications.
Apple's Swift is an open-source general-purpose programming language to compete with Objective-C in a few areas, including speed, type safety, security, and superior on-hardware performance. In comparison to other older languages, it is easy and simple to use.
Swift is on track to become the most popular programming language for iOS and beyond as:
- It's free and open-source: Swift's designers recognized that to create a defining programming language, the technology must be open to everyone. Anyone can get the source code from GitHub, build it, and even submit extraction requests to help with the project.
- Safety and Security: Its syntax drives you to write clean, consistent code, and it might feel a little harsh at times. Before a piece of software gets into production, it must be free of bugs—and Swift is no exception. Swift has safeguards in place to prevent mistakes and increase readability.
- Expressive: Swift has a syntax that is enjoyable to use, with the modern capabilities that developers demand because it takes advantage of all the strengths that have been established over decades of computer science.
- In demand: Swift was ranked 20th among the most popular programming languages in 2021 and 8th among the most liked languages, keeping its lead over Objective C.
In just a few years, the community has transitioned from the obsolete Objective-C programming language to a modern, backward-compatible programming language that is simple to learn and use. Here are the benefits of Swift for organizations looking for iOS app development.
Benefits of Native iOS App Development with Swift
Swift offers several benefits to developers, here are the top 8 of them:
1. The rapid and simplified development process
Swift programming language allows you to code easily. It does not require you to utilize sophisticated syntax and instead borrows from contemporary languages such as Python and Ruby. The overall speed of development is aided by this simplicity. Swift is simpler to read and write the language with a clean and expressive syntax and grammar. When compared to Objective-C, it is more concise, which implies that less code is necessary to accomplish the same goal. Automatic Reference Counting (ARC) automates the process of tracking and managing the app's memory usage, saving time and effort for developers. Swift is 2.6 times faster than Objective-C, according to the official Apple website, which helps with cost-cutting initiatives.
2. Effective Memory size and management
Swift provides dynamic libraries, which is a significant advantage. For a variety of reasons, dynamic libraries are preferable to static libraries. Dynamic libraries are loaded directly into memory, as a result, it drastically reduces the app's initial size and improves its performance. It will help to decrease the overall size because standard Swift libraries are included in every macOS, iOS, tvOS, and watchOS.
Also, Swift employs a technique known as Automatic Reference Counting (ARC), which is based on Objective-C's predecessor. The ARC identifies which class instances aren't in use and removes them from developers' workspaces. It effectively manages CPU or memory allocation while iOS app development.
This advancement also resulted in the publication of a stable application binary interface (ABI). As a result, Apple can support Swift on all of its platforms. Swift-developed apps take less time to install and consume less on-device memory, giving users a better app experience.
3. Interoperability with Objective-C
One can write development projects in either Objective-C or Swift because they are interoperable. That is, the Swift programming language is fully compatible with Objective-C and may be used in the same project. This is particularly beneficial for large projects that are being upgraded when new Swift features are added and subsequently incorporated into the Objective-C core.
In the same project, there are two ways this can happen:
- You can either use Objective-C parts in your Swift project or
- Add new features in Swift to an existing Objective-C project.
The two are entirely interchangeable for iOS app development.
4. Easy to Maintain
Swift is easier to maintain than Objective-C, which is one of the key reasons why developers prefer it for iOS app development. Swift merges the Objective-C header (.m) and implementation files (.h) into a single program (.swift) file, as opposed to Objective-C, which is managed in two separate files. It gives developers more time to lay out the app's logic and improve the code quality so that it operates smoothly. It eliminates the need to manually synchronize the method name and comment between files, which is one of the primary faults associated with Objective-C. So Swift does not have dependencies making it easier to maintain while iOS app development.
5. Can Grow Easily
Projects written in Swift are typically easier to grow. The fact that Swift is more likely to be supported by Apple than Objective-C should be taken into account when planning a long-term investment. Furthermore, Swift enables you to expand your workforce if necessary. This is because of the codebase's simplicity and conciseness, onboarding is reasonably quick. Swift's syntax is considered to be similar to that of normal English, making it simple to understand for new team members. It is important for businesses since training takes a lot of time.
6. Cross-Platform Support and Future Potential
another benefit of Swift app development is that the server-side Swift is compatible with the majority of common backend technologies. Employing it at both the backend and frontend speeds up the development of programs. This is largely due to code reuse, but it also affects developer time and overall resource availability.
Swift is an Apple Inc. programming language that supports iPhone, iPad, Apple Watch, Apple TV, and Mac devices.
Swift isn't just for Apple devices; it also works on Linux and Windows machines.
7. Better Stability and Safety
Swift is an excellent choice for any iPhone app development firm wishing to construct a secure and reliable iOS app for its customers. This programming language includes an excellent type system, as well as robust coding and error handling, which helps to spot faults and avoid coding errors. Swift's shorter feedback loop makes it easier for developers to spot flaws in their code and solve them right away. As a result, you'll save time and effort, and you'll have a higher chance of writing high-quality code.
When you choose safety, you may be doomed to Swift's strict feel, but our experts believe that this clarity will save time in the long run.
8. Vibrant open source community
Swift has exploded in popularity because of Apple and IBM's support. After Go, TypeScript, and Rust, Swift is one of the top five most starred languages on GitHub with a very active and thriving user community. Apple receives ongoing feedback from the public and makes modifications as needed to improve the platform.
Swift has quickly established itself as one of the most popular programming languages for creating interesting, intuitive, and user-friendly iOS mobile apps. Apple is constantly working to improve Swift and other iOS languages to make them more efficient and high-performing.
