It is a response of this API, I want to parse out image, title, description, and site name which are all present in the response. This is so far the data model I have created:
struct Metadata: Decodable{
var metatags: [enclosedTags]
}
struct enclosedTags: Decodable{
let image: String
let title: String
let description: String
let siteName: String
private enum codingKeys : String, CodingKey{
case image = "og:image", title = "og:title", description = "og:description", siteName = "og:site_name"
}
}
@IBAction func onSearch(_ sender: UIButton){
let session = URLSession.shared
let datatask = session.dataTask(with: request as URLRequest) { (data, response, error) in
guard let data = data else {
print ("Error: Handling URL request")
return }
do{
let tags = try JSONDecoder().decode(Metadata.self, from: data)
print(tags.metatags)
}
catch let jerror{
print("here", jerror)
}
}
datatask.resume()
}
Upon using this I get the following error: keyNotFound(Social_Login_api.Metadata.(CodingKeys in _7FFB0C3B2CCB4BCEDB9D03985979711B).metatags, Swift.DecodingError.Context(codingPath: [], debugDescription: "No value associated with key metatags (\"metatags\").", underlyingError: nil))
Am I declaring the struct wrong or is there an issue with handling the JSON request, any helpful insights would be great.
Edit-1: Here is the whole JSON response as requested,

Edit-final:
You sir just made my day, happy to see this result,
Optional([Social_Login_api.Item(metatags: Optional([Social_Login_api.enclosedTags(image: Optional("https://i.guim.co.uk/img/media/5d33d9276cf4388564b5bf4d42e0cd4ad8ec221e/0_230_6835_4101/master/6835.jpg?w=1200&h=630&q=55&auto=format&usm=12&fit=crop&crop=faces%2Centropy&bm=normal&ba=bottom%2Cleft&blend64=aHR0cHM6Ly91cGxvYWRzLmd1aW0uY28udWsvMjAxOC8wMS8zMS9mYWNlYm9va19kZWZhdWx0LnBuZw&s=391c7c897cafc35a55dd29b48ed544d5"), title: Optional("\'Ensuring happier lives\': Chinese media defends move to make Xi Jinping all powerful"), description: Optional("United States declines to criticise removal of term limits as liberal thinkers inside China say move deserves to be ‘mocked by civilised countries’"), siteName: Optional("the Guardian"))]))
Lastly would you point out how to get rid of these annoying optional wordings before json extracted string?
In the code,
struct Metadata: Decodable
{
var metatags: [enclosedTags]?
}
struct enclosedTags: Decodable
{
let image: String?
let title: String?
let description: String?
let siteName: String?
private enum CodingKeys : String, CodingKey
{
case image = "og:image", title = "og:title", description = "og:description", siteName = "og:site_name"
}
}
It must be CodingKeys instead of codingKeys. It is "C" not "c"
Also, the properties of the Codable Type i.e. Metadata and enclosedTags must be optional. You don't know what you will get from API. In case the properties are not optional and you don't get any one of the keys from API, the complete object will be nil.
Edit:
Use try? instead of try
let tags = try? JSONDecoder().decode(Metadata.self, from: data)
print(tags?.metatags)
Expected JSON format:
{
"metatags": [
{
"og:description": "United States declines to criticise removal of term limits as liberal thinkers inside China say move deserves to be ‘mocked by civilised countries’",
"og:image": "https://i.guim.co.uk/img/media/5d33d9276cf4388564b5bf4d42e0cd4ad8ec221e/0_230_6835_4101/master/6835.jpg?w=1200&h=630&q=55&auto=format&usm=12&fit=crop&crop=faces%2Centropy&bm=normal&ba=bottom%2Cleft&blend64=aHR0cHM6Ly91cGxvYWRzLmd1aW0uY28udWsvMjAxOC8wMS8zMS9mYWNlYm9va19kZWZhdWx0LnBuZw&s=391c7c897cafc35a55dd29b48ed544d5",
"og:title": "'Ensuring happier lives': Chinese media defends move to make Xi Jinping all powerful",
}
]
}
Sample code:
let jsonString = """
{
"metatags": [
{
"og:description": "United States declines to criticise removal of term limits as liberal thinkers inside China say move deserves to be ‘mocked by civilised countries’",
"og:image": "https://i.guim.co.uk/img/media/5d33d9276cf4388564b5bf4d42e0cd4ad8ec221e/0_230_6835_4101/master/6835.jpg?w=1200&h=630&q=55&auto=format&usm=12&fit=crop&crop=faces%2Centropy&bm=normal&ba=bottom%2Cleft&blend64=aHR0cHM6Ly91cGxvYWRzLmd1aW0uY28udWsvMjAxOC8wMS8zMS9mYWNlYm9va19kZWZhdWx0LnBuZw&s=391c7c897cafc35a55dd29b48ed544d5",

}
]
}
"""
if let jsonData = jsonString.data(using: .utf8)
{
let obj = try? JSONDecoder().decode(Metadata.self, from: jsonData)
print(obj?.metatags)
}
Output:

Edit 2:
struct Response: Decodable
{
var items: [Item]?
}
struct Item: Decodable
{
var pagemap: Pagemap?
}
struct Pagemap: Decodable
{
var metatags: [enclosedTags]?
}
struct enclosedTags: Decodable
{
let image: String?
let title: String?
let description: String?
let siteName: String?
private enum CodingKeys : String, CodingKey
{
case image = "og:image", title = "og:title", description = "og:description", siteName = "og:site_name"
}
}
Decoding JSON:
if let jsonData = jsonString.data(using: .utf8)
{
let obj = try? JSONDecoder().decode(Response.self, from: jsonData)
print(obj?.items)
}
Edit 3:
Instead of creating separate struct for pagemap, you can use containers for extracting nested information, i.e. you can use the following structs,
struct Response: Decodable
{
var items: [Item]?
}
struct Item: Decodable
{
var metatags: [enclosedTags]?
enum CodingKeys : String, CodingKey
{
case pagemap
}
enum PageMapKeys: String, CodingKey
{
case metatags
}
init(from decoder: Decoder) throws
{
let values = try decoder.container(keyedBy: CodingKeys.self)
let pagemap = try values.nestedContainer(keyedBy: PageMapKeys.self, forKey: .pagemap)
metatags = try pagemap.decode([enclosedTags].self, forKey: .metatags)
}
}
struct enclosedTags: Decodable
{
let image: String?
let title: String?
let description: String?
let siteName: String?
private enum CodingKeys : String, CodingKey
{
case image = "og:image", title = "og:title", description = "og:description", siteName = "og:site_name"
}
}
Let me know if you still face any issues. Happy Coding..🙂
