Does swift support C natively?

Question

Objective C can compile C natively. Objective C was built over C. Can swift do the same? If not what are the differences.

Answer 1

Unlike Objective-C, which is a proper superset of C, Swift has been built as an entirely new language. Swift cannot compile C code because the syntax is not compatible.

Swift can interoperate wit C code (see Interacting with C APIs article for more information). However, C code behind the APIs needs to be compiled separately, using a C compiler.
