Apple (Cocoa and Cocoa touch) development is done in Objective-C language.
You don’t have to install the Objective-C separately. Apple’s development platform is Xcode IDE
(Integrated Development Environment) which is Apple’s own development software supported on Mac systems only. Xcode comes with Objective-C support.
So if you have a Mac based system go to "https://developer.apple.com/search/?q=xcode and download the Xcode's version which is compatible with your MAC OS version.
Also keep in mind that Apple’s development is not free of cost (i.e. open source).
You have to get your product licensed on iTunes, and if t is good enough it will be launched.
