Objective-C for Swift Developers: Professional iOS Foundation

Many professional iOS development roles require the ability to maintain existing codebases or integrate powerful libraries written in Objective-C. This course helps developers who are familiar with Swift bridge the gap and become versatile engineers capable of handling any project in the ecosystem. You will transition from knowing only Swift to reading, writing, and debugging Objective-C code with confidence, focusing on how the two languages interact in modern development environments. * Understand Objective-C syntax, including headers, implementation files, and the messaging system. * Manage memory effectively using Automatic Reference Counting (ARC) and property attributes. * Apply modern features like nullability annotations and lightweight generics for better Swift compatibility. * Interface between Swift and Objective-C using bridging headers and generated headers. * Implement foundational patterns such as delegates, blocks, and categories. * Read and refactor legacy code to align with current development standards. The course begins with foundational concepts like Smalltalk-style messaging and basic syntax before moving into object-oriented patterns and interoperability. You will progress through written explanations and code-based exercises designed to reinforce your understanding of logic and structure. This course is designed for beginners to Objective-C who already have a basic understanding of Swift or general programming concepts. Expand your technical toolkit and prepare for professional iOS challenges.
