Convert Encoded String To JSON Array in Swift-CodePudding

I have an Encoded String:

("[{"carMake":"Mercedes","phone":"03001234567","insurancePolicyNo":"0123456","email":"[email protected]","full_name":"Steven Fin","registrationNo":"02134","insuranceProvider":"Michael","carModel":"Benz"}, {"carMake":"Audi","phone":"03007654321","insurancePolicyNo":"654321","email":"[email protected]","full_name":"Flemming Smith","registrationNo":"4325","insuranceProvider":"Buttler","carModel":"A3"}]")

I want to convert this into JSON array like this:

 [
    {
      "full_name": "Steven Finn",
      "insuranceProvider": "Michael",
      "insurancePolicyNo": "0123456",
      "registrationNo": "02134",
      "carMake": "Mercedes",
      "carModel": "Benz",
      "email": "[email protected]",
      "phone": "03001234567"
    },
    {
      "full_name": "Flemming Smith",
      "insuranceProvider": "Buttler",
      "insurancePolicyNo": "654321",
      "registrationNo": "4325",
      "carMake": "Audi",
      "carModel": "A3",
      "email": "[email protected]",
      "phone": "03007654321"
    }
  ]

After some searching, what I did was converting it to Dictionary, which results in:

[["registrationNo": 02134, "carModel": Benz, "phone": 03001234567, "email": [email protected], "insuranceProvider": Michael, "insurancePolicyNo": 0123456, "carMake": Mercedes, "full_name": Steven Finn], ["carModel": A3, "insuranceProvider": Buttler, "carMake": Audi, "insurancePolicyNo": 654321, "full_name": Flemming Smith, "registrationNo": 4325, "phone": 03007654321, "email": [email protected]]]

Which is not the desired result.

Did anyone knows how to achieve my desired array?

CodePudding user response：

your so called Encoded String is already json data. Try this to decode it into a Car model:

struct Car: Codable {
    let carMake, phone, insurancePolicyNo, email: String
    let full_name, registrationNo, insuranceProvider, carModel: String
}

struct ContentView: View {
    var body: some View {
        Text("testing")
            .onAppear {
                let str = """
                 [{"carMake":"Mercedes","phone":"03001234567","insurancePolicyNo":"0123456","email":"[email protected]","full_name":"Steven Fin","registrationNo":"02134","insuranceProvider":"Michael","carModel":"Benz"}, {"carMake":"Audi","phone":"03007654321","insurancePolicyNo":"654321","email":"[email protected]","full_name":"Flemming Smith","registrationNo":"4325","insuranceProvider":"Buttler","carModel":"A3"}]
                 """
                
                do {
                    let data = str.data(using: .utf8)!
                    let response = try JSONDecoder().decode([Car].self, from: data)
                    print("\n---> response \(response)")
                } catch {
                    print(" error \(error)")
                }
