有人请帮助我如何将nsdecimalnumber值转换为String这里是code.But无法正常工作.

// Return type is NSDecimalNumber
var price = prod.minimumPrice // 10

// need a String
cell.priceLB.text = NSString(format:"%f", prod.minimumPrice) as String

如何以最佳方式从此错误结果中获取消息值。我尝试了很多但从未获得价值，所以请帮助我

 BUYClient.sharedClient.createCustomer(with: credentials) { (customer : BUYCustomer?,token:  BUYCustomerToken?, error :Error?) -> Void in
                if customer != nil{
                    print(token ?? "kuch nahi aaya")
                    print(customer?.fullName ?? "kuch nahi aaya")
                }
                let customer = error.debugDescription

                print("value===\(customer)")
            }

结果 ：

     value===Optional(Error Domain=BUYShopifyErrorDomain Code=422 "(null)" UserInfo={errors={
            customer =     {
                email =         (
                                {
                        code = taken;
                        message = "has already been taken";
                        options =                 {
                            "rescue_from_duplicate" = 1;
                            value = "y@gmail.com";
                        };
                    }
                );
            };
        }})
