title: writeToFile is not writing to the file
body: <p>Well I am experiencing a problem and I've been struggling with it for few days. Here it is: when trying to write to an xml file (placed in the xcode project which I am developing) using writeToFile, writing doesn't work and I can see nothing in the xml  file although the bool value which is returned from writeToFile is being evaluated to true !! In addition, the file bytes are zero. So, I would really appreciate if anyone can help me out with that. Below is part of the code which I wrote:</p>
  
  <pre><code>//writing to a file
   NSString *pathOfFile = [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"xml"];
   NSString *dummyString = @"Hello World!!\n"; 
   NSFileManager *filemanager;
  
   filemanager = [NSFileManager defaultManager];
  
    //entering the first condition so I assured that the file do exists
    if ([filemanager fileExistsAtPath:pathOfFile] == YES)
       NSLog (@"File do exist !!!");
     else
       NSLog (@"File not found !!!");
  
  
  BOOL writingStatus = [dummyString writeToFile:path atomically:YES encoding:NSUnicodeStringEncoding error:nil];
  
      //Not entering this condition so I am assuming that writing process is successful but when I open the file I can't find the string hello world and file size shows 0 bytes
      if(!writingStatus)
      {
          NSLog(@"Error: Could not write to the file");
      }
  </code></pre>
  
  <p>I also tried this alternative, but unfortunately it didn't work too.</p>
  
  <pre><code>NSString *hello_world = @"Hello World!!\n";
  NSArray  *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
  NSString *directory = [paths objectAtIndex:0];
  NSString *fileName = @"sample.xml";
  NSString *filePath = [directory stringByAppendingPathComponent:fileName];
  NSLog(@"%@",filePath);
  BOOL sucess = [hello_world writeToFile:filePath atomically:YES encoding:NSASCIIStringEncoding error:nil];  
  if(!sucess)
  {
      NSLog(@"Could not to write to the file");
  }
  </code></pre>
