Swift was created to replace Objective-C as in use since 1983. Apple claims that Swift is much better than its predecessor and offers much more that will help developers create great applications for users. But is it really so? Let’s find out.

Is Swift the future of iOS app development?

In a very short time, almost every mobile app development company has adopted Swift. According to the recent survey, 59% of developers are building an iOS app using Swift, yet 39% prefer Objective-C for this process.

The main benefit of using Swift is that it has a fairly simple and small code that allows application developers to quickly create fully functional applications. Yahoo Weather and LinkedIn were the first to create the Swift-based application. Plus, iOS apps written with Swift are easier to maintain, lighter, and ready for the future.

Here are some of the main advantages of using Swift over Objective-C to create applications:

1. Swift is faster: C ++ is known as one of the fastest coding languages ​​in the industry, and Swift’s performance is very similar to C ++. In addition, Apple regularly releases updates that aim to improve the speed and stability of Swift so that iPhone application development can be carried out smoothly. Objective-C is slower than Swift because it contains the legacy C API.

2. Swift is easier to read: Objective-C has been in use for the last three decades and therefore has a more clunky syntax, while Swift, on the other hand, is quite easy to read and learn. Like C ++, C #, JavaScript, and Python, Swift code is also flexible and simple. Application developers who are familiar with the languages ​​mentioned above will choose Swift.

3. Swift Playground encourages interactive coding: This playground is a new tool that has proven beneficial to hobbyist programmers. It offers an interactive coding environment where developers can test the execution of their code, without having to create the entire project.

4. Swift requires less code: Swift-based applications can be developed with very less code. Whereas Objective-C is full of code that makes learning hectic, especially for newbies. Other than that Objective-C uses string manipulation and Swift uses string interpolation without any use of tokens and placeholders. Lower code equates to better readability and high reusability.

5. Swift is more secure: Unlike Objective-C, Swift codes do not use pointers. These indicators can sometimes lead to application security vulnerabilities. Pointers can create a barrier to identifying and correcting errors that sometimes slow down an application’s performance. With Swift, application developers feel more secure and can protect their application from unwanted errors.

6. Swift is a full-featured coding language: Apple recently released the second version of Swift which comes with several major changes. One of the significant changes is that developers can now use any operating system to develop iOS applications. Along with that, they can now bring their Objective-C based project to the Swift without compromising on quality.
