It seems like you're interested in Objective-C, which is a programming language used primarily for macOS and iOS development. While the context provided doesn't directly address Objective-C, it does touch on related topics such as memory management and interoperability with Swift, which is Apple's more modern programming language.
For instance, in the session Analyze heap memory, there is a discussion about reducing reference counting overhead in Objective-C code. This involves techniques like marking methods as OBJC_DIRECT to allow inlining of Objective-C method calls, which can help reduce retain and release traffic.
If you're interested in how Swift interacts with Objective-C, the session Consume noncopyable types in Swift might be relevant, as it discusses Swift's handling of types and memory management, which can be important when working with Objective-C APIs.
If you have specific questions about Objective-C or its integration with Swift, feel free to ask!
What’s new in UIKit
