Swift vs Objective-C

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. Swift is only 6 years old now, and Swift 5 was released a year ago in March 2019. It shows that Swift is less stable than Objective-C, but it’s due to constant improvements and development. It is salient whether there is an easy-to-use environment, how expensive it is, and if there are any alternative solutions on the market. If you don’t know whether to choose Swift or Objective-C for the iOS app you are planning to develop, you will find out by the time you’ve read this article.

Maintaining Two Code Files In Objective

If you miss a pointer in the code, perhaps nil value, the app will crash. This approach allows programmers to find and fix bugs quickly. As a result, the code will be cleaner and easier to understand. Such features as generics, optionals, and type interference make an app developed in Swift less inclined to contain unnoticed bugs. Suffice to say, both of these languages have a lot to offer in terms of app development and can prove useful based on its use. Swift’s code-processing speed is nearly on par with C++ for both the FFT and Mandelbrot algorithms which are used for benchmarking.

Smalltalk gives it the object syntax, and the non-object syntax comes from C. Now, understanding the ideal programming language for iOS app development needs you to consider the features, differences, pros, and cons of both the options that you have on hand. All the above-mentioned reasons added together, make Swift an ideal partner for cloud based app development. But time over time, we have seen that only that programming language survives which makes developers’ lives easier, gives coders space to experiment, is cost-effective for businesses.

  • It includes late binding, dynamic dispatch, extensible programming, etc.
  • A great example of this is ARC – I’m actually slightly alarmed by the fact that I didn’t have to learn how to explicitly deallocate memory in OC because of it!
  • They also have more build issues as well, something you won’t want to deal with when you’re just starting out.
  • Nowadays the development world is arguing about which language Swift or Objective-C is better for iOS development.
  • The LLVM compiler and Xmind figure out the requirements and automatically complete the incremental builds.

This code can be updated, changed or recompiled without recompiling the application that uses this library. Dynamic libraries are automatically included in the AppStore’s download package. Static libraries are linked at the last step of the compilation process after the program is placed in memory.


Swift is a rising star among iOS developers and likely to encapsulate the future of mobile development beyond 2021. However, some complex projects that already involve Objective-C coding will require expertise in the older programming language. Objective-C was developed by Brad Cox and Tom Love in the 1980s. This language was created by adding the features of Smalltalk to C. Now, C is a functional programming language, and Smalltalk is an object-oriented programming language.

Swift vs Objective-C

In Swift coding, unified memory management developers should not give attention to each digital object, but rather concentrate on the general logic of the application and its features. The main characteristic lies in its maturity, since it has been used and tested for many years for Apple’s software. Netherland-based company TIOBE (stands for “The Importance Of Being Earnest”) created an index of popularity of various programming languages called TIOBE programming index. Index is calculated based on the number of search requests related to different languages in the six popular search engines – Google, Google Blogs, Yahoo!

The grammar and syntax used in Swift are much easier than other programming languages. Swift projects are arguably much more future-proof than the ones written in Objective-C. Swift usage has greatly expanded since its introduction, and it currently used in a third of all Cocoa open source projects. If the pace stays the same, the number of such projects will equal the number of Objective-C ones.

Voice searches were a part of futuristic films for a long time, but now they are part of our everyday… All of these elements need to be taken into consideration when you’re deciding which language to go with. It’s easier to identify and fix any problems if you just focus on a small portion at a time. For those of you who are in the middle of a small project and want to switch, it’s reasonable.

A no-op leads to unpredictable behavior, which is the enemy of programmers trying to find and fix a random crash or stop erratic behavior. Check out the detailed Swift vs Objective-C comparison and analysis prepared by our software outsourcing company to make the best choice. To learn more about Swift’s string interpolation and other new features, go here. The code in the if statement will only execute if x has a value, and assign it to y. Note that we don’t need to unwrap y, it’s type is not optional since we know x is not nil.

Even where performance is critical the amount of code that needs to be heavily optimised will tend to be small and you could switch to a faster language (e.g. C) for just those parts. Swift is also developed from Apple to appeal to new programmers because it is similar to languages such as Ruby and Python than it is Objective-C. Can anyone enlighten swift vs objective c me on this, preferably from their own experience. Objective-C has been around since the 1980s, but that marks one of its drawbacks. Its syntax is quite old and difficult for modern-day developers who are used to easier syntax found in Python and JavaScript. Also, Apple is moving toward Swift and encourages developers to create apps using Swift.

This means that all variables and types are automatically scoped by the module. You don’t need to use a module prefix to access an externally scoped variable. If there is a name collision between a local variable and an external variable, Swift will automatically resolve it and use the local variable.

Swift vs Objective-C

Let’s now check out the advantages of Swift over the Objective-C programming language. In contrast, Swift is not limited to Apple OS. In 2015 it became an open source and cross-platform programming language. This takes away the unsafe pointer management and at the same time provides interaction with long-standing Objective-C and C code bases.

Comparative Advantage Of Objective

Apple’s goal with Swift was to design a simple and understandable language. The difference between Objective-С and Swift is that Swift uses all the industry standards that help write clean code. Due to the enhanced readability and simple syntax, any developer who is familiar with JavaScript, Python, or C++ can learn the Swift language quickly.

Use Of Dynamic Libraries

The C language offers many useful libraries and features which Objective-C can leverage. While Swift isn’t directly interoperable with C or C++, it can still leverage those languages through Objective-C. Each programming language has its benefits and its drawbacks. Let’s look at the key differences between Objective-C and Swift’s feature sets.

Swift and Objective-C are both statistically typed languages that use the sameiOS SDKand the high-qualityLow Level Virtual Machinecompiler. There are differences, however, that impact app performance and we’ll describe them below. This is easily handled with Swift working across procedural and object-oriented code using Cocoa API. Swift has a hyperactive support community that provides numerous dynamic libraries and APIs for extending app features. Swift supports Apple platforms such as iOS, macOS, watchOS, and tvOS. Swift’s LLVM compiler does permit Android app development using frameworks such as Scade, SwiftCore, Dispatch, and SwiftFoundation, but there is no support from Apple in this regard.

Performance And Speed Comparison

As the natural language of the iOS framework, Objective-C is a superset of C, but adds additional features like a bracket-style messaging syntax. Modern features – Being a young language, it has modern features such as optimised memory management, dynamic libraries, better app monetization, etc. Seasia Infotech is equipped with a team of Swift programmers who can help you in your iOS mobile app development. If you want a quality iOS mobile application, you can opt for Seasia developers and let them handle the procedure for you. The major reason to introduce Swift was to cater a proficient and simple way of programming.

The Strengths Of Objective

Consider the code below for writing a simple string variable, called NSString, in Objective-C. For modern programmers who works on languages like Python or JavaScript, https://globalcloudteam.com/ this is a very complex syntax. Swift automatically tracks the advanced feature of memory usage. This makes it one of the fastest language for app development.

Fewer Name Collisions With Open Source Projects

Developers who write the performance-sensitive code often go back to clear C for those inner loops. The official Apple website claims that Swift is2.6 timesfaster than Objective-C. Howeversome studiesindicate that the difference is not as dramatic.

Apart from professional support, it’s also helpful to be part of a community of experts who will back you up with their experience and knowledge. Objective-C is almost as old as the hills, so your application will run on any version of iOS available. It means you need to analyze what devices your users have and decide if it’s ok for you to limit yourself to those with iPhones and iPads released after 2013. To be honest, there aren’t many people who still use devices as old as 7 years, so it shouldn’t be an issue. To learn Swift, you do NOT need prior knowledge of Objective C. In fact, Swift is easier and requires no prior coding knowledge to learn it.

AppCodeis another option to consider that’s also compatible with Swift and has tools to support this new language. So if you like the support of all modern IDEs, consider sticking with Objective-C. You don’t need to find a new IDE if you’ve been using Xcode to write iOS apps. Depending on your project, one of the first things you’ll do as a developer is set up a timeline. You may find yourself spending hours upon hours converting to new syntaxes even after a minor update.

Also, we cannot get all queries answered through Stack overflow and Google. Because of its ease of use compared with Objective-C, it was quickly adopted by developers. Swift development started at Apple in 2010, and it was released to the public in 2014.

It also addresses things like null pointers, which are common programming errors. On the other hand, Swift’s easy to read and write syntax is driving its popularity in the iPhone app development world. Objective-С, on the other hand, developed back in the 80s, is a more complex language, both to learn and implement. Since then, the industry standards have shifted and more concise programming languages such as Swift itself have been developed. According to Statista, below is a chart that showcases the most popular programming languages.

If there are no project requirements that dictate otherwise and no objections from your team, you should always create production apps using tools that you familiar with. This prevents accumulation of technical debt, i.e. unfixed bugs or unimplemented features that will otherwise plague the project as you learn as you go. Even though Apple has provided a garbage collector for Objective-C, it is not as effective as the Swift code. Simpler syntax and compilation type checking help Swift overcome Objective-C. In addition, Swift supports dynamic libraries, which can also improve application performance. Therefore, when it comes to Performance, Swift has the upper hand over Objective-C.

The better you know the language and its tools, the easier it is to avoid mistakes. The better and more suitable technology you choose, the higher the performance. With higher performance come better UX, easier refactoring and maintenance, and more. That enables infinite Innovation to create a holistic, sustainable future.
