解析json並在swift中使用JSonJoy保存到modelClass中？

Question

這是我的json結構----->如何使用JSONJoy保存模型類。 JSON：

Optional(<__NSSingleObjectArrayI 0x61000000b570>(
    { 
    locationC = 116789; 
    locationN = testrtyuio; 
    siteName = lab; 
    } 
) 
)

請檢查：

struct LocationDetails: JSONJoy { 
    var locationC: String? // based on your datatype change it 
    let locationN: String? // based on your datatype change it 
    let siteName: String? // based on your datatype change it 
    init(_ decoder: JSONDecoder) throws { 
     locationC = try decoder["locationC"].get() 
     locationN = try decoder["locationN"].get() 
     siteName = try decoder["siteName"].get() 
    } 
} 

let data = try Data(contentsOf: file) // data is your json format 
var locationDetails = try LocationDetails(JSONDecoder(data)) 
print(locationDetails) // Output : LocationDetails(locationC: Optional("116789"), locationN: Optional("testrtyuio"), siteName: Optional("lab")) 
print(locationDetails.locationC!) // Output : 116789
