ios - How call a function objective c with args in swift -

i have next function in objective c

+ (nsstring *)getnslog:(nsstring *)pstring, ...{     va_list args;     va_start(args, pstring);     nslogv(pstring, args);     va_end(args);      return [[nsstring alloc] initwithformat:pstring arguments:args];  } 

how can call function swift or convert code swift such when call function can be:

getnslog("my value1 =  %@ value2 = %@","hello","world") 

note second param not have alias how this.

getnslog("my value1 =  %@ value2 = %@", args:"hello","world") 

i solved follow:

in objective c change code this:

+(nsstring*)getnslog:(nsstring*)pstring args:(va_list)args{  nslogv(pstring, args);  va_end(args);  return [[nsstring alloc] initwithformat:pstring arguments:args]; } 

in swift app delegate add

extension myclass { class func getnslog(format: string, _ args: cvarargtype...) -> nsstring?     {     return myclass.getnslog(format, args:getvalist(args))     } } 

now can call function

nslog("%@", myclass.getnslog("%@,%@", "hello","world")!) 

i based in post duplicated how call objective-c variadic method swift?

thanks.
