read blob data extra argument bytes in call swift

I am trying to read blob data from sqlite, but I get Extra argument 'bytes' in call error.

Here is my code:

var len = sqlite3_column_bytes(compiledStatement, 0)
var point = sqlite3_column_blob(compiledStatement, 0)
var dbData:NSData? = NSData(bytes: point, length: len)// ERROR: Extra argument 'bytes' in call

if dbData != nil
{
   arrDataRow.addObject(dbData!)
}
