followed the function video to build a function that works in xcode to add two floats together however doesn't work here

float addTwo(float a, float b);
int main()
{
    float a = 1.0;
    float b = 2.0;
    printf("addTwo %f\n", addTwo(a, b));
    return 0;
}
float addTwo(float a,float b) {
    return a + b;
}

Here's the build

You've done too much - the question states No need to write the main function. Just write out the implementation for the addTwo function. So you just need to enter the function you have, correctly, written:

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