Explore the inner workings of Swift 2 in this comprehensive conference talk from GOTO Berlin 2015. Delve into the history and motivations behind Swift's creation, comparing it to Objective-C and examining its compilation and execution processes. Learn about Swift's key features including modules, types, protocols, and memory optimization techniques. Discover the intricacies of static and dynamic dispatch, and gain insights into Swift's relationship with LLVM. Analyze the Swift compilation pipeline, intermediate representation (IR), and Swift Intermediate Language (SIL). Investigate name mangling, v-tables, and use the SIL Inspector tool for a deeper understanding. Evaluate Swift's performance and conclude with a summary of its advantages and potential future developments.
