Ah the excuses when facts are put on the table.

"Fast. Swift is intended as a replacement for C-based languages (C, C++, and Objective-C). "

-- https://www.swift.org/about/

"From its earliest conception, Swift was built to be fast. Using the incredibly high-performance LLVM compiler technology, Swift code is transformed into optimized machine code that gets the most out of modern hardware. The syntax and standard library have also been tuned to make the most obvious way to write your code also perform the best whether it runs in the watch on your wrist or across a cluster of servers.

Swift is a successor to both the C and Objective-C"
