Objective-C was created in 1984 as an extension of C. It added Smalltalk style messaging and Object Orientation to the C language. It was the standard programming language on macOS and iOS until the introduction of Swift in 2014.

Why is this technology on hold?

Swift is now pretty stable and has been the constant focus of Apple with continuous language improvements, exclusive revolutionary new frameworks like SwiftUI and Combine. Community efforts today are pretty much all around Swift.

Apple continues to offer great interoperability between Objective-C and Swift and will not abandon support for Objective-C anytime soon, but at this point migrating from Objective-C to Swift is definitely worth the investment.
