Swift Language Use the C standard library


Swift's C interoperability allows you to use functions and types from the C standard library.

On Linux, the C standard library is exposed via the Glibc module; on Apple platforms it's called Darwin.

#if os(macOS) || os(iOS) || os(tvOS) || os(watchOS)
import Darwin
#elseif os(Linux)
import Glibc

// use open(), read(), and other libc features
