Xcode Objective C - syntax is wrong

Hi I am new to xcode and objective C, I have a section of code that I want to add by know that the syntax is wrong please can somebody help me

Code:

int j, i=0;
    
    //while ((nextLine = read.readNext()) != NULL)
    
    //{ //while the line inputed is not empty do
        
       for(j=0;j<=6;j++)
    
               
       
            
       // data[i][j]=nextLine[j].toLowerCase();
        
        i++; // this increses i with 1
    
//}
           
That is the code that I am trying to add to this one 
  datasetfile = @"german_credit";
    CSVReader *csvReader = [[CSVReader alloc] initWithFile:datasetfile];
    //NSLog(@"getColumnHeaderAtIndex: %@", [csvReader getColumnHeaderAtIndex:0]);
    //NSLog(@"getColumnContentsAtIndex: %@", [csvReader getColumnContentsAtIndex:0]);
    NSLog(@"getRowAtIndex: %@", [csvReader getRowAtIndex:1]);
    testLabel.text = [NSString stringWithFormat:@"getRowAtIndex: %@", [csvReader getRowAtIndex:1]];
    //NSArray *stringArray = [NSArray arrayWithObjects:@"nextLine", @"readNext", @"data",NULL, nil];
    //NSLog(@"count = %d", [stringArray count]);
