I have a `rating` field that might have 3 which parses to JSONValue.integer or 3.4 which parses to JSONValue.floating and I need to use float. I was using exceptions that was causing the program to be slow as per the profile information. Now I have used an if clause as suggested by Adam in the answer. Though the execution time for the relevant function that used exceptions earlier reduced the program was still taking the same time.

Or search forum for fastest Json parser in the world.  I use asdf 
though, which is fast enough and has a nice interface.
