Swift vs Objective C: Assessing Popular iOS Programming Languages

Each has its specific upsides and downsides, so creators find it daunting to pick the right one. This article gives a detailed assessment of Swift vs Objective-C to aid users in making an informed decision on which is ideal. Objective-C has a lot of information and resources available for developers. It also has a large community of Objective-C developers. Nonetheless, Swift can easily compete with it in terms of documentation and communities.

  • Since Objective-C is not young, it can work with earlier versions of iOS and macOS, facilitating the creation of universal projects.
  • Due to the superclass structure of Objective-C, developers can add methods to classes at runtime without the need to recompile them later.
  • But Swift is not portable across platforms, and you can’t just copy-paste it.
  • There are many reasons why non-technical product owners are unable to know which one is best.
  • Although it appeared in 1983, this object-oriented language is still considered a reliable tool for developing complex software.

Even though Swift is a lot newer than Objective-C, its openness means that there are also a wealth of resources available to aid developers in their projects. You will not be able to use Cocoa Touch to develop Apple TV or Apple Watch apps using Objective-C. This is an important limitation depending on your strategy. If you’re https://globalcloudteam.com/ using Objective-C, the best choice for development is Xcode. You could potentially choose to use another development environment such as AppCode, but this environment will most likely still need Xcode to function properly. Again, because Swift is young, it doesn’t support versions earlier than iOS 7.0 and macOS 10.9.

What is SwiftUI?

One of the critical tasks for creating native mobile applications is to decide on the appropriate programming language. For iOS apps, the most common variants to choose from are Swift or Objective-C. It was positioned as a faster and more efficient programming language for creating iOS and macOS applications. It has become the fastest-growing programming language in history. Unlike Objective-C, Swift was built for the average developer. It is easy to learn and has a syntax that allows programmers to self-learn.

Eventually, the app gained widespread currency in more than 20 cities inside and outside the United States and was finally acquired by a third-party company. Swift is a newer programming language developed by Apple. Swift was released back in 2014, and developers are still getting used to it. Some core concepts in Swift are the same as in Objective-C, such as dynamic dispatch, extensible programming, and late binding. But Swift exceeds the ability to catch software bugs. It also addresses things like null pointers, which happen to be a common example of programming errors.


It differs in syntax from other programming languages, so it is pretty hard for beginners. Objective-C programming language has been tried and tested for a longer time than Swift, and more stable and mature. Since Swift is still developing, it needs regular updates while Objective-C requires no more development. It is also more reliable and has a lot of great third-party frameworks. Swift adds language features that make developers’ code safer, faster, more reliable, and more predictable compared to Objective-C.

They both have the corresponding app programming interfaces and frameworks . Apple has announced Swift as a powerful and intuitive programming language for macOS, iOS, watchOS, and tvOS that completely can replace Objective-C. There is even faster level if you set to ‘Fastest, Unchecked [-0fast]’ …

The APP Solutions team developed an iOS mobile application for this project based entirely on Swift. Aside from outsourced application development, we contribute a lot to in-house projects. Watching US presidential elections 2016 rule supreme, we decided to avail of this opportunity and improve our skills in developing multiplayer games with Unity. There is no denying that you can develop apps faster in Swift, but that doesn’t mean it is the end-all decision to choose a programming language for your project.

Swift Programming Language – An Overview

Later, in 2010 Apple launched version 4 of the iPhone OS . The updated version comprised not only the new features in software but the changes in the Developer Agreement. With its light, flexible syntax and numerous features to guard against common coding errors, Swift is simply a joy to program with. Give it a try yourself – you’re almost certain to agree. A good place to start is Apple’s official documentation for the language. Objective supports ARC inside the object-oriented code.

With that said, even though I’ve talked about lots of the positive features of Swift coding, it’s still very new. As a result, it’s a safe and clean way for you to write code. Ultimately this will prevent a large number of crashes. It was first released back in June 2014, so iOS developers are still getting used to it.

Swift is safer

Users can include any edits at any developmental phase. When Swift stepped into the field, users faced the dilemma of determining which would suit their project the best. In themost commonly usedsoftware design list, Swift shows 5.1% while Objective-C is favored by 2.8%.

One of its most promising features is what Apple calls Protocol-Oriented Programming, a paradigm which may have a huge impact on software development in the future. Another key attribute is that Objective-C applications can inspect all defined classes at runtime while allowing for custom classes and new methods. Certain Apple classes and scripting languages capitalize on this to offer helpful capabilities. For instance, AppleScript uses this characteristic to automate repetitive coding tasks, while UndoManager uses it to provide developers an easy rollback mechanism. Objective-C was introduced in the 1980s, and introduced tools that eventually became the Cocoa platform for iOS, macOS, watchOS and tvOS development. It’s based on an object-oriented programming approach, which revolves around dividing code into classes and methods.

If you forget a pointer in the code, perhaps, null value, the app crashes. This makes it easier for developers to find and fix bugs quickly. As a result of this, the code written in Swift is cleaner and easier to understand. Features such as optionals, generics, and type interference make sure that your app is less inclined to contain unnoticed bugs.

Swift is continuously updated and requires improvement. Thus, a significant drawback arises – the need to switch to the latest versions, which entails additional costs of money and time. In 2015, Apple made Swift open source to all interested. Now any software developer, college student, or beginner can develop and optimize this language. In the differences, we shall highlight the features of each so that you get all the information you need.

After that, Lattner got a couple of developers to help him officially continue work on the project. But Swift is not portable across platforms, and you can’t just copy-paste it. So, Android as the minimum would need the execution environment for Swift – and that’s just to start. Google also has to change all its standard libraries for Swift, as well as to implement the language support in APIs and SDKs. Below we gathered and shared Swift advantages that we’ve discovered throughout our experience using this new language. There are five reasons why you should use Swift that our developers have spotted while working on the project Nuwbii in particular.

Functional Programming Features

Memory is automatically handled, and defining purpose is effortless with an optimized syntax. Performance is crucial when it comes to User Experience, but maintenance and refactoring are important as well. The company claims that Swift is nearly three times faster than Objective-C.

Website Vs. Web Application: Understanding the Differences

Our daily routine consisted of a number of problems, we needed to resolve regularly, such as news feed loading issues, duplicate content and weather report update fails. We also worked on adding new app blocks and features and modifying the existing ones according to current users needs. Fill the expertise gap in your software development and get full control over the process. Most startups and some mid-level companies are starting to write their iOS apps completely in Swift.

Regardless of whether you use Objective-C or Swift for building your app, you surely want to build a great iOS User Experience for your users. Native Apple apps look better and run faster than hybrid apps. Since both Objective-C and Swift are native languages, either one of these languages is capable of making a high-quality app for iOS. It is rare to find developers who think that Objective-C is the more stable language. Swift receives constant updates and development and was in part built to improve app stability.

Well, Swift eliminates lots of classes that are perceived as unsafe code. Using Objective-C means that you’ll get language-level support for your object literals and object graph management. According to Apple, this language objective c vs swift offers object-oriented capabilities as well as a dynamic runtime. Here’s a quick glance at some of the key highlightsfor each programming language. App Development Everything you need to know about app development.

Now, in order to pick up the right programming language for your project, you need to consider the pros, cons, features, and differences of both choices you have on hand. Objective C is hard to learn because its syntax is complicated. It is different from many other popular programming languages that’s way Swift is preferred over it. Swift integrates seamlessly with the Cocoa API and Cocoa Touch framework, which are both foundations of iOS development and provide a cavalcade of powerful design tools. Swift developers can also integrate with server-side frameworks like Vapor and Kitura, or machine learning platforms like TensorFlow.

Ultimately, the language features of Swift can really help improve the experience with iOS app development. For those of you with extensive knowledge of other advanced object-oriented programming languages such as Ruby or Python, you won’t have trouble learning Objective-C either. Apple claims that Swift is almost 3 times more productive than Objective-C. But practical studies show that the difference in performance is pretty small (Swift’s advantage) because both iOS app programming languages use the same SDK .
