There was a problem hiding this comment.
One alternative is introducing a protocol you can cast to, e.g:
protocol _OptionalProtocol {
associatedtype Wrapped
var _asOptional: Wrapped? { get }
}
extension Optional: _OptionalProtocol {
var _asOptional: Wrapped? { self }
}
let x = Int?.none as Any
if let y = x as? any _OptionalProtocol {
print(y._asOptional == nil) // true
}
