Objective-C was created in the early 1980s by two programmers named Brad Cox and Tom Love. However, it didn't become popular until it was bought by NeXT in 1988 for their NeXTSTEP operating system. After NeXT was bought by Apple in 1996, it became the main programming language for Mac OS X and later the iPhone, iPod Touch and iPad. In recent years, Swift has been more popular than Objective-C.
