title: Import .csv data into a array
body: <p>I'm using Objective-C the last years. 
  Now I'm trying the Xcode 6 beta 4 with swift. </p>
  
  <p>I want to import a .csv form my webserver to an array. My old code in Objective-C was: </p>
  
  <pre><code>NSString *stringURL = @"https:// [URL] /versionen/versionen.csv";
  NSURL  *url = [NSURL URLWithString:stringURL];
  NSData *urlData = [NSData dataWithContentsOfURL:url];
  if ( urlData )
  {
      NSString *csvResponseString = [[NSString alloc] initWithData:urlData   encoding:NSUTF8StringEncoding];
      NSArray         *MZVersionDatenZeilen = [csvResponseString componentsSeparatedByString:@"\n"];
      NSEnumerator    *MZVersionEnumerator = [MZVersionDatenZeilen objectEnumerator];
      NSMutableArray  *MZVersionDatenArray = [NSMutableArray arrayWithCapacity:[MZVersionDatenZeilen count]];
      NSString        *MZVersionZeile;
      while (MZVersionZeile = [MZVersionEnumerator nextObject])
      {
          [MZVersionDatenArray addObject:[MZVersionZeile componentsSeparatedByString:@";"]];
      }
  }
  </code></pre>
  
  <p>How could I do this in Swift?
  Is there a best practices - recommendation? </p>
