The thing is that they are larger in size because external programs are built in the executable files. Dynamic libraries are smaller because only one copy of dynamic library is being stored in memory. So, if you choose to stay with Objective-C, you should recognize that you will ignore the dynamic libraries support provided by the Swift language.
Blog Explore hundreds of posts we have on app development. Though Swift get more and more support, libraries, there is still tons of old apps which written in OC need to be maintained. Thus companies will hiring guys who could use OC to maintain their apps, especially the big companies.
Execution Time
The LLVM compiler and Xmind figure out the requirements and automatically complete the incremental builds. As a result, the Objective C header (.h) file and implementation (.m) file are combined in one single (.swift) program code file. Objective-C was created from C and it depends on it when it comes to changes and swift vs objective-c improvements. Developers have to maintain two separate files of code in Objective-C to improve the efficiency and the developing time of an application. It also requires human effort in synchronizing method names and comments. What’s important to understand about Objective-C’ safety is that it uses null pointers.
- As we touched on in the previous section, Swift has a modern and simple syntax.
- As you know, it’s very important to make sure that you and your clients are all on the same page when it comes to this estimated timeline.
- There’s a good chance going with Swift would yield quicker results.
- It is an interesting fact that, so far, no one actually uses Swift in Android programming.
It’s relatively young and has replaced tools like CocoaPods and Carthage, which were previously the default choices of developers. Alongside Apple platforms, Swift is also compatible with Linux. Overall, it’s a rapidly growing programming language with a great potential.
What is Swift?
Objective-C mainly because it’s been around for over 30 years now. But then, documentation for Swift is constantly updated. Also, keep in mind that it’s open-source, so there are many more third-party sources for you to find. You should start with Apple service for developers and dedicated Swift webpage.

Advantages of Objective C:
With the community’s involvement, these goals are definitely attainable, and we are excited to see what the future of Swift will hold. Google Trends measures the popularity of a search term in Google. We can compare Swift vs. Objective-C and see that Swift receives more search volume than Objective-C. Stack Overflow tag trends measures how many questions get asked about a specific language every month on Stack Overflow. Comparing Swift vs. Objective-C, we see that quickly after Swift was released, it surpassed Objective-C. And while both are in decline at the moment, Swift still holds a heavy lead.
These libraries can help optimize your app’s performance and reduce file size. Objective-C developers do not enjoy the support of dynamic libraries within their development process. Objective-C’s ARC is limited in functionality only to support theCocoa API, which is Apple’s native application programming interface for macOS. For developers who use Core Graphics, the code does not access these APIs. This is a limitation that really hurts Objective-C developers as opposed to Swift developers. There are many more important new things to learn about in Swift, like Generics, interaction with Objective-C libraries, closures, optional chaining, and operator overloading.
Memory Management in Objective-C vs. Swift
A single tutorial cannot describe thoroughly a new language, but I have no doubt much more will be written about learning Swift programming. Unlike Objective-C, Swift does not require you to create separate interface and implementation files for custom classes and structures. Contrary to Objective-C, you do not need separate interfaces and implementation files to create custom classes and structures in Swift. Because Swift is a new language and it is at its development stage, people have been learning and adopting the programming language.
Swift’s syntax is inspired by Python, which is considered the easiest language to learn. So, Swift syntax https://globalcloudteam.com/ is also easy for developers to pick up. Swift automatically tracks the advanced feature of memory usage.
Swift vs. Objective-C: An iOS Developer’s Perspective
You have to understand the ideal programming language at its core with the pros, cons, differences, features, and everything important crystal clear in your mind. They are similar to that of general object-oriented programming languages. Swift utilizes simple and concise coding, with fewer lines needed for the same operation than Objective-C. It boasts convenient maintenance, requiring just a single code file. Furthermore, Swift supports the integration of dynamic libraries.
