How does Swift’s performance compare to Objective-C for mobile applications?

Swift outperforms Objective-C in the development of mobile applications to its modern, optimized syntax, and memory handling system. Swift code is concise, with faster compile-time and execution time for common tasks. Additionally, it has strong typing and safety features that protect against many runtime errors. Moreover, Swift’s performance is enriched by the LLVM compiler, which is used by Apple to compile Swift code into optimized machine code. Objective-C is still powerful, but Swift enables the development of high-performance applications that respond to Apple platforms because of its advanced features and optimizations.
