Hello,
I’m having some odd results with closures that take Void as a parameter, and
was wondering if this was expected behavior or a bug. Specifically, I have the
following closure:
> Welcome to Apple Swift version 4.0 (swiftlang-900.0.45.6 clang-900.0.26).
> let foo: (Void) -> () = {}
Trying to call foo without parameters fails, of course:
> foo()
error: missing argument for parameter #1 in call
foo()
^
<#Void#>
However, the fix-it doesn’t seem to work:
> foo(Void) // or even: foo(Void())
error: argument passed to call that takes no arguments
foo(Void)
^~~~~~
while
> foo(()) // Executes with no errors
works. Since Void is a typealias for () this should work, shouldn’t it? Just
wanted to confirm that I’m not going crazy here.
Regards,
Saagar Jha
