Today, almost every iPhone app development company is choosing to use Swift over Objective-C when developing iPhone applications. Swift was introduced to the world by Apple in 2014, and completely revolutionized the way every iPhone app development company writes apps. This is because, Swift is a modern, simple programming language that’s less error-prone as compared to Objective-C, which has made the work of almost every iPhone application developer significantly easier. What follows are reasons why Swift trumps Objective-C.1. It requires less code
Compared to Objective-C, Swift is more compact, and so, requires significantly less code. In Swift, the amount of code that is needed for string manipulation, as well as repetitive statements is much lower than what Objective-C requires. In addition to this, Swift consists of features of a modern programming language, as it allows an iPhone application developer to add two strings together with a “+” operator— something that isn’t possible with Objective-C.2. It’s faster, much faster
As Swift allows an iPhone application developer to fix code when it’s being written instead of fixing the bugs later, almost every iPhone app development company prefers Swift to Objective-C. If you’re using Objective-C, you’ll notice that nothing takes place when you attempt to call a method with an uninitialized pointer variable (nil). This line of code them becomes a no-op, which could result in bugs and other unpredictable behavior. With Swift, a compiler error is generated when bad code is written, and a run-time crash is triggered if a nil optional variable is used so that the behavior becomes a lot more predictable.3. It’s more interactive
With Swift’s Playgrounds, every iPhone application developer is able to test the latest algorithms, as well as graphics routine, without having to create a complete iPhone app, which is another reason why almost every iPhone app development company prefers using this programming language. In addition to this, Swift offers a feedback loop that allows iPhone programmers to develop a large amount of code while obtaining feedback about its development.4. It has dynamic libraries
With the advent of Swift, there was a big shift from static libraries to dynamic ones, which made iPhone app development for almost every iPhone application development service an easier task. This is because dynamic libraries are basically coded--that is executable--that’s linked to an application. And so, an iPhone application developer can easily submit the app, as well as the libraries that are digitally signed, along with a certificate of development. This is precisely why Swift is considered to be a more modern programming language that’s open to change.5. It’s future-driven
Because of Swift’s multiple capabilities and perks, IBM and Apple have decided to invest in Swift together, which will result in nothing but a bright future for the programming language. As the IBM cloud allows developers to develop, deploy, and share Swift resources, Objective-C is now being updated to become more compatible with Swift.
