Here what I can find regarding your question:

we can't have [(type1,type2):type3] in Swift without declaration of new temporary 
struct type and implement Equatable for it.


It would be reasonable, IMO, even before we support the full generalization of 
extensions on non-nominal types, to make tuples of Equatable/Hashable/Comparable 
elements conform to the same protocols by fiat.

So... it seems like we all (including core team) want this, but this will not be 
implemented in Swift4, as I understand.

Welcome to the group of people who thinks that the character from Monopoly had 
a monocle, including myself. You've just experienced a transdimensional jump 
from your universe without even notecing, but where Swift 4 actually had 
hashable tuples. :)

Jokes aside, I haven't read anything about it in this universe, at least not 
for Swift 4.

[swift-users] did i just imagine tuples were going to be hashable in swift 4?

I thought I read that tuples would finally be hashable in swift 4, allowing for 
them to be used in dictionaries/sets, but now that i google for it, i find no 
mention of it.

are there any plans?  so often i just want to quickly create a dictionary set 
from a tuple of an integer or string or two, and not being able to do so is 
just plain annoying.
