Objective-C courses can help you learn the basics of object-oriented programming, memory management, and the Cocoa framework for macOS and iOS app development. You can build skills in creating user interfaces, handling data with Core Data, and integrating APIs for enhanced functionality. Many courses introduce tools like Xcode for coding and debugging, as well as Interface Builder for designing app layouts, helping you apply these skills in real-world app projects.
