var variableThatWillBeAssignedAFunction: ((Int) -> Int)?
To make it more readable, you can also use a typealias:
typealias IntegerTransform = (Int) -> Int
var variableThatWillBeAssignedAFunction: IntegerTransform?
I would like to create an optional variable that can be assigned a function ( or can be nil). I'm guessing it would look something like this but the following code does not compile.
var variableThatWillBeAssignedAFunction: {(Int) -> Int}?
Thanks for your help

I was so close 😂
Haha yes it takes a while to get used to :) I edited my answer with a more readable way, maybe this will help.
