swift - Tuple member extraction in closure arguments -

considering array of tuple :

var tuplearray = [(string, int)]() tuplearray.append(("bonjour", 2)) tuplearray.append(("allo", 1)) tuplearray.sort { (t1 , t2) -> bool in     let (_, n1) = t1     let (_, n2) = t2     return n1 < n2 } 

i make closure shorter doing :

tuplearray.sort { ((_, n1) , (_, n2)) -> bool in     n1 < n2 } 

first: possible?
second: if possible syntaxe?

thanks

well, can use short closure syntax:

tuplearray.sort { $0.1 < $1.1 } 

see the official guide short closure syntax, .1 tuple index access.
