The question is not whether the language has a native code compiler, as that rarely has a profound effect on the runtime speed of a language. Some native code languages are slower than VM and interpreted languages. And native code != native code. Objective-C and Swift both have native code compilers. But they are slower than C and C++ on the same platforms, for various reasons, such as: the runtime environment itself and how the runtime works, and, in the case of Swift, the organization of its LLVM code prior to final compilation.
