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 findReasonAndTerminate() {
let reason: String = ….
fatalError(reason)
}
main.swift:
guard let data = buildData() else { findReasonAndTerminate() }
Currently the work around is to add another fatalError like this:
guard let data = buildData() else { findReasonAndTerminate(); fatalError }
but it would be nice to have some attribute like @noReturn:
@noReturn
func findReasonAndTerminate() { … }
