title: Swift Data File not being created
body: <p>I am trying to save an array of a user-created class named "TopTenData".  The code I used follows.  Running the code indicates the file is created, but the file is NOT created. When I navigate to the path I do not find the desired file.  Any help would be appreciated. </p>
  
  <pre><code>func writeArrayToPlist(array: [TopTenData]) {
      if let arrayPath: String = createArrayPath() {
          (array as NSArray).writeToFile(arrayPath, atomically: false)
          print("Array written successfully")   
          print(arrayPath)   // navigating this path shows no files
      }
  }
  
  func createArrayPath () -&gt; String? {
      if let docsPath: String = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true).last {
          return ((docsPath as NSString).stringByAppendingPathComponent("myTopTenData") as NSString).stringByAppendingPathExtension("plist")
      }
      return nil
  } 
  </code></pre>
