Objective-C: What It Is, Main Differences, and Features

Dynamic typing improves class usage flexibility while avoiding typecasting for every written line of code. As a result, it is feasible to modify the structure and goal of classes throughout the development process. So, if you’re interested in entering the world of programming languages, this certain one is highly recommended. Inheritance – Inheritance lets you create classes even when you already have an existing one! You’ll also be able to autonomously prolong the original program and create a modification while keeping the same features. C and Objective-C are almost the same — except Objective-C programming language is the object-oriented language version of C language.

JavaScript and HTML/CSS are very familiar programming languages to people even outside the coding world. Not as much adaptation required – many APIs still have a lot of catching up to do for apps that are developed with Swift. This means that it may be easier to apply Objective-C to an iOS mobile application. Swift is the programming language that was first launched by Apple in June 2014. Objective-C yields all warts you’d expect from a language formed on C.

Disadvantages of Objective-C

SwiftUI replaces the old View and ViewController classes and provides a modern API for creating user interfaces. SwiftUI is component-based, making it easy to create complex user interfaces by compositing simple components. Components can be nested to create complex hierarchies, and they can be reused across multiple apps and screens. Each element has a well-defined set of properties that you can use to configure its appearance and behavior. In addition to its powerful declarative syntax, SwiftUI also offers efficient animation.

Advantages (Pros) of Objective C

Alibaba Cloud offers highly flexible support services tailored to meet your exact needs. I’m thinking of writing a binary tree with C++ and using it with Objective C objects. Where the return value is false for some internal error, and true for success. This is better than an opaque type, but the smart pointer is even better – pretty obvious if you are used to writing modern C++. I’m mainly using Objective-C for the UI and other Apple APIs, and C++ for internal audio processing and other information handling.

However, other programming languages deserve some recognition, too — one of them being Objective-C. Objective-C programming is a programming language that is used for general-purpose activities. While it is not specific to any particular platform or system, it can greatly aid in developing a variety of other frameworks. Objective-C programming adds messaging capabilities to the programming language C. By nature, they require longer time for students to think, organize and compose their answers. Swift can only be used to create apps designed to run on the IOS 7 or later.

Built With the Future of Development in Mind

You can ask more questions, it takes less time to complete a multiple-choice question compared to an open question. Respondents don’t have to formulate an answer but can focus on the content. It is a list of methods that any class can declare itself to implement.

Disadvantages of Objective-C

Type-checking and error handling features prevent program crashes and mistakes, allowing developers to spot problems quickly and fix them on the go, reducing bug fixing time. Objective-C is built on top of C, therefore namespacing is required. All classes in an Objective-C program should be distinct worldwide. As a result, developers employ the practice of prefixing class names with ‘NS’ to avoid conflict. We utilize the ‘NS’ prefix for the Foundation Framework’s class and the ‘UI’ prefix for UIKit’s classes.

Some Scala features, such as functional programming and continuations, are less familiar for coders. Besides, they say that Scala’s syntax is more complicated when compared to Java. 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.

The emphasis is on quickness, performance, and outdoing the predecessors. According to benchmark tests conducted by individual developers, the initial boast of a 40 percent improvement in speed over Objective-C has been verified. Because of its age, the programming language developed decades ago lacks many current capabilities, resulting in poor performance. This feature aids in the comprehension of the developer’s thinking and code simplicity.

Requires more maintenance – Objective-C is an outdated language, so you’ll need to keep updating apps developed using it. Encapsulation – This feature lets you limit other users from having DIRECT access to state values of the variables. You can use it to adapt to new requirements and set different variables as to write-only or read.

  • By convention, developers place the interface in a header file and the implementation in a code file.
  • Swift offers more powerful tools and modern coding solutions for simpler, but expressive coding, app safety, and performance.
  • Some modern desktop applications that use C++ are Adobe programs and Microsoft Windows OSX.
  • The syntax might look overwhelming at first, but you’ll be able to get the hang of it easily.
  • It’s the foundation of OS-X and iOS and was mostly exclusive to Apple products.
  • This article is an English version of an article which is originally in the Chinese language on aliyun.com and is provided for information purposes only.
  • Both the languages are rooted in C, but they are two completely different languages.

Objective-C is reflective, more focused on classes and was designed by Brad Cox and Tom Love in a company named Stepstone and first appeared in the year 1984. Now being used as a general-purpose object-oriented programming language by Apple in its operating system https://globalcloudteam.com/ and APIs. Swift, one of the emerging programming languages, was designed to replace Objective-C. The second advantage of the Objective-C programming language is its runtime capabilities. A program developed using Objective-C will be able to run more dynamically.

Most C++ developers actually work in the game development industry. Aside from the other C languages, C has served as a guide for other languages too! In fact, JavaScript, Java, Swift, and Golang even use the same syntax that C started. This ios swift vs objective c is important since low-level languages are more complicated since they use more symbols.

The point here is that there are multiple forms the program can take. This one is the best if you intend to set up translation firewalls (e.g. use PIMPL and forwards to reduce dependencies). As well, the ObjC object is already going through locking and allocations, so it’s not a bad point to allocate a C++ type. If you have several declarations, you may prefer to create a wrapper type for your implementation to reduce individual allocations. And the only reason I haven’t voted to close is because I already did that.

Disadvantages of Objective-C

Let’s take a look at some of the advantages of this Programming Language. Objective-C was once very popular when there were no superior alternatives. Today, many lighter and simpler languages (i.e., React Native, Swift) and several coders refuse to learn an outmoded language. It’s entirely conceivable that the number of Obj-C developers will plummet in a few years. In our article “How to choose a tech stack for your project?” we have discussed this issue in detail to help you make the right decision. Despite that, Objective-C remains an important language that serves as the foundation of Apple’s operating system and inspiration for other C code families.


With our specialists.We have been creating successful projects for many years and love sharing our knowledge and experience. Of course, that’s because it’s a huge part of the foundation of Apple’s operating system. Meanwhile, for Objective-C, categories run directly in compile time and can only be used to extend a certain type’s functionality. Objective-C has been used to develop software for MANY Apple products.

Objective-C 2.0 added support for marking certain methods in a protocol optional, and the compiler will not enforce implementation of optional methods. A non-valid object pointer has the value nil; conditional statements like “if” treat nil like a null pointer, so the initialization code will not be executed if returned nil. I’ve just moved things over to use more C++ and use composition with smart pointers to reduce dependency. This is better than an opaque type, but the smart pointer is even better – pretty obvious if you are used to writing modern C++. In the C language, the #include pre-compile directive always causes a file’s contents to be inserted into the source at that point. The target class may not have received any messages prior to the posing.

The Components of the Objective-C Programming Language

Objective C is well tested language because it has existed from many years. There is a lot of code written in Objective C. It has many well-documented, third-party frameworks. We’ve been in the business for over 12 years and have delivered over 200 mobile and web projects. While Swift is easier to write and understand when you’re used to it, it’s NOT very beginner-friendly. The syntax might look overwhelming at first, but you’ll be able to get the hang of it easily. With Swift, coding for any type that conforms to protocol WITHOUT knowing the specific type is possible.

Swift has some features like generics, optional, type inference which make its apps less prone to errors. With 13 years of experience in the IT industry and in-depth technical training, Peter could not be anything but our CTO. He had contact with every possible architecture and helped create many solutions for large and small companies.

Objective C can simplify this process if the user takes the time to understand the incremental parts. Objective C is a software development program that has been around since the early 1980s. It was invented and designed by a team of computer scientists who were looking to create tools that ios swift vs objective c could provide reusable code. Objective-C Configuration & Deployment Services were created by this pair, who were looking for a way to create more efficient technology. Objective-C programming language has become Apple’s main language in developing iOS and the OS X operating system.

Programmers typically use C++ when they need low-level control over a system’s resources while maintaining high performance. What’s great about this is you can isolate the “groups of legos” from one another. Object-oriented programming involves a group of languages that gives you a clearer structure to work with since you’re mimicking real-world building. They’re often ineffective as a teaching tool, they’re easy for students to cheat, and they can exacerbate test anxiety. Objective-C requires that the interface and implementation of a class be in separately declared code blocks. By convention, developers place the interface in a header file and the implementation in a code file.

It quickly grew popular because it was much easier to understand and use compared to other programming languages in those times. C allowed developers to work with hardware at a low level while still using readable syntax. Objective-C is in competition with Swift, which is a newer iOS programming language.
