Actually, Objective-C is still in use, but it is likely to become less prevalent in the coming years. In 2021, Objective-C was gradually being replaced by Swift as the preferred language for iOS and macOS development by Apple. Swift offers modern features, better performance, and improved safety compared to Objective-C, which made it more attractive to developers.
It's important to note that Apple often encourages developers to use the latest tools and technologies, and they have been actively promoting Swift as the language of choice for new app development. However, the adoption of Swift versus Objective-C may vary among developers and organizations, depending on their specific needs and existing codebases.
Objective-C has been around for a long time and was the primary language for iOS and macOS development before Swift was introduced. While its usage was gradually decreasing, it remained relevant for maintaining and updating older apps and libraries written in Objective-C.
Swift is Apple's preferred and modern programming language for developing iOS, macOS, watchOS, and tvOS applications. It was introduced by Apple in 2014 and has since gained popularity among developers due to its ease of use, performance improvements, and safety features. Many new apps were being developed in Swift because of its advantages over Objective-C.
Also Cocoa API and related things with Cocoa Touch respectively as they are written in the Objective-C language. It's not very likely that they will ever be re-written in Swift.
"Anyway, we can say it's not dead, but it will be soon!"
But what's funny is that major technology companies still require Objective-C as a requirement in their job postings.
I think they need to invite technical hr's to another seminar to discuss that old technology. :)
