Typo, should be instance not istance.

You’re welcome. I don’t think there is a better way of doing that. However you
can build some wrappers with some shortcuts.
func createInstance<T>(of _: T.Type, _ istance: T) -> T {
return istance
}
let myGreatFunc1 = createInstance(of: Function.self) {
return "\($0) \($1)" // Or whatever
}

It feels a bit strange to write it like that, but yes, that would work. Thanks!
(It will prevent me from having to touch up old functions when adding more
parameters to the signature as the project evolves)
