Pass C ++ char * to Swift

To do

Returns char * in C and treats it as a String in swift


Now that I've created HelloFrameWork (Cocoa Touch Framework), I want to use the methods in it from swift.

C language

hello.h should be a public header in Xcode


#ifndef HELLO_H
#define HELLO_H

char* getHello();



char* getHello() {
    return strdup("Hello");


let hello_char = getHello()
let hello: String = String(cString: hello_char)
//Memory release


Official Documentation Using Swift with cocoa and Object-C


Using strdup () doesn't seem to be beautiful either. To write better, you should give a destination argument on the swift side and put a value there.
