Я пытался преобразовать быструю ошибку в Objective C NSError, но при этом получил cra * sh.

if let convertedError = error as NSError? {

}

Спасибо, Ники

От ошибки к NSError пытается получить доступ к errorCode и errorDomain.

extension CustomError: LocalizedError {
public var errorDescription: String? {
    return "Some localized description"
}
}

extension CustomError: CustomNSError {
    public static var errorDomain: String {
        return "Some Domain Name"
    }
    public var errorCode: Int {
        return 204 //Should be your custom error code.
    }
}
