Swift doesn't support exceptions AFAIK. It supports weird error handling 
that looks similar to exceptions, but is really just a standard return.

i.e. this:

do
{
    try someFunctionThatErrors(arg)
}
catch(Exception ex)
{
    // handle ex
}

really compiles like this:

var _err : Error?
someFunctionThatErrors(arg, &_err)
if(_err != nil)
{
    let ex = _err!.exception
}
