code won't say anything other than hello world when run

I follow the instructions on the screen perfectly but everytime I run my program it says hello world; I tried erasing that part but then nothing works. Please help

I do not see anything wrong with that code. Maybe shut down Xcode and try again. You can try pressing command-shift-k... Also when you post code if you can use 3 ticks and the name of the laungage (`objectivec) and end with 3

#import <Foundation/Foundation.h>

int main(int argc, const char * argv[]) {

    int curretAge;
    curretAge = 36;

    float currentWeight;
    currentWeight = 124.75;

    float currentHeight;
    currentHeight = 66.0;

    double currentWeightPerInch;
    currentWeightPerInch = currentWeight / currentHeight;

    NSLog(@"Current Height is %f", currentHeight);
    NSLog(@"Current Weight is %f", currentWeight);
    NSLog(@"Current WeightPerInche is %f", currentWeightPerInch);

    return 0;
}
