Interesting, but I strongly dislike the use of whitespace indentation for new statements/segments of code,

it

   will

         get  
             tedious  

                   when
                         you
                              are
                                  nesting
                                           multiple
                                                    blocks
                                                           of 
    code.

And I like it when Xcode highlights the brackets/parenthesis because it's just easier to pick up ( and ) and { and } from a line of text.
