If you are using closures in your Swift code, you may become familiar with the shorthand parameter syntax. That is, parameter names are often represented as $0 or $1.
You may or may not be aware that these continue, in that for each parameter the shorthand name is incremented by one each time ($2 and $3 up to the number of arguments as is required in your code).
