You can make something that can do that fairly easily:
struct TextualError: LocalizedError {
var errorString: String
init() {
self.init("")
}
init(_ string: String) {
self.errorString = string
}
var failureReason: String? {
return self.errorString
}
}
Then, you can just:
throw TextualError("Must Sterilize!”)
Or:
var error = TextualError()
error.failureReason = "Must Sterilize!”
throw error
