Apple introduced Swift in 2014, a new programming language for help to create best iOS mobile applications that are given iOS developers an alternative to Objective-C, an object-oriented superset of the C programming language that’s been the most important of iOS development thus far. The Swift language is built to be able with all of the existing iOS development such tools: Objective-C, Xcode, and the Cocoa framework but its ease of use and boost features mean it’s quickly starting to replace Objective-C. So, now in this article, we’ll learn about some reasons why you should get on a group with the Swift programming language for your next iOS application development project if you haven’t already.
What about the Objective-C?
Objective-C is a well-established programming language that was made by the Stepstone Company in the early 1980s. And it was released to the public in 1988 when Brad Cox and Tom Love published a book, “Object-Oriented Programming: A developed Approach”. In the 1980s, Objective-C was licensed by NeXT Pc, Inc. to build the NeXTStep system and was eventually acquired by Apple. And also you can see it’s how to become the standard for many years in the area of iOS apps development.
What is swift programming language used for?
Swift is a multi-paradigm, general-purpose, compiled programming language developed via Apple Inc. for macOS, iOS, watchOS, Linux and.tvOS Swift is created to work with Apple’s Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C (ObjC) code written for Apple products.
If we want to develop in Swift because is faster more than others, but it is not the only factor you should consider when making crucial business decisions. Here are the pros and cons of these two languages?
Pros of Objective-C:
- Object-C has existed for numerous years and is well tested
They have various lines of code written in Objective-C. As well there are many well-documented, third-party frameworks, and there is an answer to nearly every question.
- Good compatibility with C and C++
Also, Objective-C is a superset of C and thus operating with C or C++ code works relatively smoothly.
- It is stable
If you want to develop your own application in Objective-C, you probably will not need to spend money on migrating the app to a new language version after a few months.
Cons of Objective-C
- it’s difficult to understand to learn about the programming language
If we compared the Objective-C from many other popular programming languages, and memory management is quite complicated. This is why it’s easier to learn Swift by developers familiar with Objective-C than vice versa.
- it’s also a decreasing number of developers
As Objective-C is not easy to learn, there are more new developers learning Swift than learning Objective-C. In a different way, experienced developers familiar with Objective-C are usually familiar with Swift, or at least ready to learn it.
An application developed in Objective-C could be potentially easier to hack than its Swift alternative. Also, Objective-C is good known and has existed for many years; it also means that reverse engineering tools are also well developed.
Pros of Swift
- Swift is safer
Because of its features: options, generics and type interference – apps developed in Swift are less prone to bugs and crashes than apps developed in Objective-C.
- Apple is focused on Swift
Apple often develops this language and supports the community. On every WWDC there is a group of amazing technical talks about Swift; the premise indicating that Swift should be taken seriously.
- You will be more popular with your developer’s team
According to a 2017 survey of Stack Overflow Developers, Swift is at the forefront of the most liked programming languages, while Objective-C is one of the most dreaded.
Cons of Swift
Migrations and changes
This is maybe the weakest point in app development with Swift. Although, it’s already not as painful as it used to be and should definitely improve after introducing ABI stability. Swift used to be lots of difficulties due to the very frequent changes implemented in the language. Developers needed to migrate applications to the newest versions. This costs time and money. Luckily, with the passage of time, changes in subsequent versions of the language are getting smaller.
In today’s scenario, developing an application in Swift is a better choice. Although, we can think of two cases where you should choose Objective-C:
- An application is already written in Objective-C, and you only required adding new features. It can be used together with Objective-C, which means you can use these two languages in one project successfully. Although this may not be the best option. Managing an app that is built in two languages can cause problems. You must be aware that some edge cases can occur. You required a developer who is skilled and experienced in both languages.
- You required using C++ or C third-party framework extensively. This situation occurs relatively rarely. In this situation, as Objective-C is a superset of C, it may be worth considering using this language.
When it comes to developing a new iOS project, the decision about which programming language to use is important. It will affect other choices, for example, the architecture or used frameworks. Swift programming language is safer, enjoyable and faster, from a developer’s perspective. In another way, decisions are always made in a specific context. Swift is good, but it’s not a silver bullet. There are still some cases where Objective-C may be the right choice.
