value = "-258.38";
},
{
code = shipping;
title = "Shipping & Handling (Flat Shipping Charge - Flat Shipping Charge)";
value = 400;
},
{
area = taxes;
code = tax;

};
title = Tax;
value = 0;
},
{
area = footer;
code = "grand_total";
title = "Grand Total";
value = "2725.37";
}
);
"weee_tax_applied_amount" = "<null>";
};
}
I need to fetch values from total segments.The code is shipping and value is Shipping & Handling (Flat Shipping Charge - Flat Shipping Charge.
I tried to parse the json using the below code
if let res = json as? [String:Any]
{
if let dict = res as? [String:Any]
{
if let total = dict as? [[String:Any]]
{
}
}
}
I am getting value till dict.But i am getting nil in the total variable.
How to get the total segments value?

Answer 1

you're missing out to mention the inner key path of the dictionary. hope this is what you're trying to do
if let res = json as? [String:Any] {
if let paymentMethods = res["payment_methods"] as? [[String:Any]] {
}
if let totals = res["totals"] as? [String:Any] {
if let items = totals["items"] as? [[String:Any]] {
}
}
}

Use this to get the total_segments and value of all code keys:
var codes = [String]()
if let res = json as? [String:Any] {
if let totals = res["totals"] as? [String:Any] {
if let totalSegments = totals["total_segments"] as? [[String:Any]] {
for segment in totalSegments {
if let code = segment["code"] as? String {
codes.append(code)
}
}
}
}
}
