Code is good but still saying wrong

My code is good, i've even tried it on Xcode and it works but it still give me an error

float addTwo(float a, float b);

    float one = 20.2;
    float two = 30.5;
    float result =  addTwo(one, two);

    printf("%f", result);

float addTwo(float a, float b){

    return a + b;

I passed this challenge with:

float addTwo(float a, float b){
   return a + b;

The rest of the code showing the workings aren't needed. It just wants the method.

The compiler in the challenges will 'fail' things that Xcode will 'pass'. Xcode doesn't know what the question is asking, of course.
