title: How do I add files to /Documents directory in App Sandbox
body: <p>Here is where I am:</p>
  
  <pre><code>I have JSON files I need to mount into Objective C Objects
  
  I have an XCode Project
  
  I have dragged the folder of JSON files into my project and 
  created a blue "Documents" folder off of the root of the project.
  
  However, it does not appear in the app sandbox in the ~/Library/... folder. 
  </code></pre>
  
  <p>Despite searching both this site and others for a set of instructions to accomplish the above I have come up short.</p>
  
  <p>I have also reviewed Apple's docs, and have found tangential information but not a straight forward description of how to accomplish the above.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
  NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
  NSString *lessonsDirectory = [documentsDirectory stringByAppendingPathComponent:@"/lessons"];
  
  NSString *filePath = [lessonsDirectory stringByAppendingPathComponent:@"/52aa2b6e9af9b73896095404.json"];
  NSLog( filePath );
  
  NSData *data = [NSData dataWithContentsOfFile:filePath];
  
  //THE NEXT LINE ERRORS OUT -&gt; "data parameter is nil'
  NSArray *json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
  </code></pre>
