We should move this thread to swift-users.
Here is something that I just tried:
|func foo(_: Int, _: Int) {} func boo(_: (Int, Int)) {} type(of: foo) ==
type(of: boo) //=> true ; (((Int, Int)) -> ()).Type let tuple = (0, 42)
foo(tuple) // Tuple splat was removed => Error boo(tuple) // Expected => Okay |
IIUC, as soon as
SE-0110(https://github.com/apple/swift-evolution/blob/master/proposals/0110-distingish-single-tuple-arg.md)
was not marked as "implemented" yet according to
https://apple.github.io/swift-evolution/, we still have some rudiments of
older design.
I expect that implementation of SE-0110 will separate types
(Int, Int) -> ()
and
((Int, Int)) -> ()
Also implementation of SE-0110 should remove implicit Void parameter in
function defined with no parameters
func f() {}
func g() {}
f(g()) // now works, will be error
func foo(f: () -> ()) { f() }
foo {x in print(x)} // now works, will be error
I'd really like to know when this proposal will be implemented : in Swift
3.x or in 4.x
