Question: Is there an operator for zip?

[amadeu01]

There is a Zip function in Overture
https://github.com/pointfreeco/swift-overture#zip-and-zipwith

However, I would like to know whether exists an operator for it

Hi @amadeu01! The functionality of zip is typically achieved using curry alongside pure, and <*> (apply).

zip(with: User.init)(optionalId, optionalName, optionalEmail)

// vs.

pure(curry(User.init)) <*> optionalId <*> optionalName <*> optionalEmail

A shortcut to using pure is to sometimes use the map infix operator (<$> in Haskell, <¢> in this library):

curry(User.init) <¢> optionalId <*> optionalName <*> optionalEmail
