I have a following sample json file I want to do it with modal classes but am not sure how to do this in code.
{
"countryCodes": [{
"country_code": "AF",
"country_name": "Afghanistan",
"dialling_code": "+93"
},
{
"country_code": "AL",
"country_name": "Albania",
"dialling_code": "+355"
},
{
"country_code": "DZ",
"country_name": "Algeria",
"dialling_code": "+213"
},
{
"country_code": "AS",
"country_name": "American Samoa",
"dialling_code": "+1"
}
]
}
My modal class is as follows
import Foundation
class CountryModal : NSObject, NSCoding{
var countryCodes : [CountryCode]!
/**
* Instantiate the instance using the passed dictionary values to set the properties values
*/
init(fromDictionary dictionary: [String:Any]){
countryCodes = [CountryCode]()
if let countryCodesArray = dictionary["countryCodes"] as? [[String:Any]]{
for dic in countryCodesArray{
let value = CountryCode(fromDictionary: dic)
countryCodes.append(value)
}
}
}
/**
* Returns all the available property values in the form of [String:Any] object where the key is the approperiate json key and the value is the value of the corresponding property
*/
func toDictionary() -> [String:Any]
{
var dictionary = [String:Any]()
if countryCodes != nil{
var dictionaryElements = [[String:Any]]()
for countryCodesElement in countryCodes {
dictionaryElements.append(countryCodesElement.toDictionary())
}
dictionary["countryCodes"] = dictionaryElements
}
return dictionary
}
/**
* NSCoding required initializer.
* Fills the data from the passed decoder
*/
@objc required init(coder aDecoder: NSCoder)
{
countryCodes = aDecoder.decodeObject(forKey: "countryCodes") as? [CountryCode]
}
/**
* NSCoding required method.
* Encodes mode properties into the decoder
*/
@objc func encode(with aCoder: NSCoder)
{
if countryCodes != nil{
aCoder.encode(countryCodes, forKey: "countryCodes")
}
}
}
and
import Foundation
class CountryCode : NSObject, NSCoding{
var countryCode : String!
var countryName : String!
var diallingCode : String!
/**
* Instantiate the instance using the passed dictionary values to set the properties values
*/
init(fromDictionary dictionary: [String:Any]){
countryCode = dictionary["country_code"] as? String
countryName = dictionary["country_name"] as? String
diallingCode = dictionary["dialling_code"] as? String
}
/**

*/
func toDictionary() -> [String:Any]
{
var dictionary = [String:Any]()
if countryCode != nil{
dictionary["country_code"] = countryCode
}
if countryName != nil{
dictionary["country_name"] = countryName
}
if diallingCode != nil{
dictionary["dialling_code"] = diallingCode
}
return dictionary
}
/**

@objc required init(coder aDecoder: NSCoder)
{
countryCode = aDecoder.decodeObject(forKey: "country_code") as? String

}
if diallingCode != nil{

}
}

How do I use these models to get the value of to say India +91 code? I am new to swift so I am clueless as to how to use these models.

I have a following sample json file I want to do it with modal classes but am not sure how to do this in code.
{
"countryCodes": [{

You can try
struct Root: Codable {
let countryCodes: [CountryCode]
}
struct CountryCode: Codable {
let countryCode, countryName, diallingCode: String
enum CodingKeys: String, CodingKey {
case countryCode = "country_code"
case countryName = "country_name"
case diallingCode = "dialling_code"
}
}
let res = try? JSONDecoder().decode(Root.self,from:jsonData)
print(res.countryCodes)
res.countryCodes.forEach {
if $0.countryCode == "DZ" {
print($0.diallingCode)
}
}
hello, how do I use this struct, suppose in a VC where i want to get a specific country dialing code? for eg if let jsonData = NSData(contentsOfFile: filePath) {} after this what should i write?
