Converting from Swift string to const char*

Question

I\'m trying to pass a const char * to an old C library converted from a Swift string in Swift.

This is the C function I\'m calling:

artnet_node artne         


        

Answer 1

Simple way for Swift 3

var ipAddress: String = "192.168.1.43"
var verbose: Int = 1
artnet_node artnet_new((ipAddress as NSString).utf8String, verbose)
