What is Swift?
Swift is an object-oriented programming language launched by Apple. Swift is inspired by designers from many other popular languages such as Objective-C, Rust, Haskell, Ruby, Python, C # and CLU
Swift is great for writing software, whether for phones, computers, servers… Swift is a safe, fast programming language; combines the best of modern language thinking with Apple's broad technical foundation.
Swift is friendly to new programmers. Writing Swift code in a playground allows you to experiment with the code and see the results immediately without the overhead of building and running the app.
Swift is determined to eliminate common programming errors by applying modern programming patterns:
- Variables are always initialized before use.
- The array index is checked for an out-of-bounds error.
- Integers are checked for overflow.
- The options ensure that the values
nilhandled clearly. - Memory is managed automatically.
- Error handling allows controlled recovery from unexpected errors.
Swift code is compiled and optimized to take full advantage of modern hardware. The standard syntax and library are designed around the principle: clear instructions on how to write code that works best. The combination of safety and speed makes Swift a great choice for everything from “Hello, world!” for the entire operating system.
Swift has been in the making for many years, and it continues to evolve with new features and capabilities.

The benefits of Swift
The ability to develop mobile applications and test their results in real time will help programmers' coding process become much faster and easier. In addition, not having to run compiler and test programs too often will also save hardware power for developers. Instead of focusing on testing and testing small features, Swift programmers can spend more time performing tests at a higher level of integration more thoroughly.
The second benefit of Swift is that the code lines are very short and easy to read. This will speed up application development and increase efficiency for future maintenance/patching.
Finally, and perhaps most importantly, if Swift creates applications with less hardware stress than Objective-C, we will enjoy a more impressive gaming experience on iOS devices. When combining Swift with Apple's new Metal platform, even the old A7 processor can deliver the most impressive graphics experiences.
Swift's Weaknesses
Swift's biggest weakness will be the young age of this programming language. More specifically, to use Swift, developers will have to relearn a completely new programming language. The tech industry often enjoys mastering the latest and greatest technologies. But the iOS app industry has become so big that thousands of people have spent months mastering Objective-C; Objective C training for iOS has become an important industry; There are companies that focus solely on this programming language (and iOS). Since Swift will definitely replace Objective-C completely, iOS app developers will take a considerable amount of time to master Apple's new language. This may reduce the growth rate of the Apple application ecosystem.
Another concern is junk apps. Because Swift will make the application development process much easier than before, the number of poor quality applications appearing on the App Store may increase. However, this is not necessarily a real concern for Apple and its users. Through this transition period, Swift will help bring iOS and Mac apps to the next level.
“Hello world” with Swift
Theoretically, Swift is promising to become the most “perfect” programming language for application developers. What Apple needs to do is make sure its promises come true.
We are so used to technology companies releasing impressive numbers as proof that their products are the best, more advanced than all “old” products and competitors. . However, in the world of programming, things are not so simple. It will take a long time for programmers to verify what Apple says. It took a long time for the mobile industry to understand the benefits of Swift. This is a huge change, so big that you wouldn't be wrong in saying that for the mobile app development industry, Swift is as important as the App Store when it first launched.
