By the way, return Never used to be called @noreturn, so you weren't far
off!

The last line should be `fatalError(findReasonAndTerminate())`.

Change you `func findReasonAndTerminate()` to `func
findReasonAndTerminate() -> String`.
Then you can use `fatalError(func findReasonAndTerminate())`.

I believe returning Never does what you want, e.g.
import Foundation
func findReasonAndTerminate() -> Never
{
let reason: String = findReason()
fatalError(reason)
}
func findReason() -> String
{
return "some reason"
}
func buildData() -> Data?
{
return nil
}
guard let data = buildData()
Is there any way to mark a function as “no return”?
Reason: The compiler generates an error when the else block from a guard does
not terminate the execution by either a return or a fatalError. I want to call
out to a function and raise the fatalError in that function.
func findReasonAndTermina
