Objective C - Legacy iOS
Interested in training to become an iPhone programmer? The Objective-C Programming training course teaches you the foundations of the Objective-C programming language. This Legacy Objective-C class covers the Xcode development environment and Cocoa programming framework. You will use Cocoa to create applications in the same way that macOS itself is created. Much of Cocoa is implemented in Objective-C, a superset of C, so you will be able to draw upon your existing C or C++ background.
