I'm using Swiftui to create a covid app.
I got a json form from api and I was pasing
"totalCase": "26,732",
"recovered": "24,395", The json format contains a comma, so it is not accurate output.
ex) totalCase: 26, recovered: 24 I want to erase the comma and express all the numbers.
{
"resultCode": "0",
"resultMessage": "정상 처리되었습니다.",
"korea": {
"countryName": "합계",
"newCase": "97",
"totalCase": "26,732",
"recovered": "24,395",
"death": "468",
"percentage": "51.56",
"newCcase": "79",
"newFcase": "18"
},
"seoul": {
"countryName": "서울",
"newCase": "25",
"totalCase": "6,081",
"recovered": "5,500",
"death": "78",
"percentage": "62.47",
"newCcase": "20",
"newFcase": "5"
}

Answer 1

You can get your string remove the commas (thousand separator) and the enclosing quotes as well. One you have done that you can decode your json string and treat the properties as integers. You can still use SwiftyJSON if you would like to or using Codable as shown bellow:
struct Root: Codable {
let resultCode: Int
let resultMessage: String
let korea, seoul: Country
}
struct Country: Codable {
let countryName: String
let newCase, totalCase, recovered, death: Int
let percentage: Double
let newCcase, newFcase: Int
}
if let result = response.data {
do {
let cleaned = result.replacingOccurrences(of: ",(?=\\d{3})", with: "", options: .regularExpression)
.replacingOccurrences(of: #"\"(\d+)\""#, with: "$1", options: .regularExpression)
.replacingOccurrences(of: #"\"(\d{1,2}.\d{1,2})\""#, with: "$1", options: .regularExpression)
print(cleaned) // { "resultCode": 0, "resultMessage": "정상 처리되었습니다.", "korea": { "countryName": "합계", "newCase": 97, "totalCase": 26732, "recovered": 24395, "death": 468, "percentage": 51.56, "newCcase": 79, "newFcase": 18 }, "seoul": { "countryName": "서울", "newCase": 25, "totalCase": 6081, "recovered": 5500, "death": 78, "percentage": 62.47, "newCcase": 20, "newFcase": 5 }}
let root = try JSONDecoder().decode(Root.self, from: Data(cleaned.utf8))
print(root) // "Root(resultCode: 0, resultMessage: "정상 처리되었습니다.", korea: __lldb_expr_11.Country(countryName: "합계", newCase: 97, totalCase: 26732, recovered: 24395, death: 468, percentage: 51.56, newCcase: 79, newFcase: 18), seoul: __lldb_expr_11.Country(countryName: "서울", newCase: 25, totalCase: 6081, recovered: 5500, death: 78, percentage: 62.47, newCcase: 20, newFcase: 5))\n"
} catch {
print(error)
}
}

You can use a number formatter to convert this format to an int
let numberFormatter = NumberFormatter()
numberFormatter.locale = Locale(identifier: "en_US")
numberFormatter.numberStyle = .decimal
Example
let string = "6,081"
if let value = numberFormatter.number(from: string)?.intValue {
print(value)
}
