I have a macOS project using objective-c. Basically I new to creating application for macOS. I don't not objective-c or swift but I have a nodejs file that I need to run and not sure how to.

#import <Cocoa/Cocoa.h>

int main(int argc, const char *argv[]) {
  
  - (NSString *)runCommand:(NSString *)commandToRun
  {
      NSTask *task = [[NSTask alloc] init];
      [task setLaunchPath:@"/nodefile.js"];

      NSArray *arguments = [NSArray arrayWithObjects:
                            @"-c" ,
                            [NSString stringWithFormat:@"%@", commandToRun],
                            nil];
      NSLog(@"run command:%@", commandToRun);
      [task setArguments:arguments];

      NSPipe *pipe = [NSPipe pipe];
      [task setStandardOutput:pipe];

      NSFileHandle *file = [pipe fileHandleForReading];

      [task launch];

      NSData *data = [file readDataToEndOfFile];

      NSString *output = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
      return output;
  }
  
 
  return NSApplicationMain(argc, argv);
}
