Temp JSON data - Swift - json

Question

So I am trying to create a temp JSON depending on whether a listener is tuned into a podcast or a radio station.
Because we already have all the podcast info we don't need to ask a remote JSON for it. But we still need to have the ability that when the MusicPlayer is playing that in the View it shows the cover, artist and title.
So my thinking was create a simple JSON Struct inside the MusicPlayer class and when the media player sends the data to the following
func getArtBoard(artist: String, song: String, cover: String) {
guard let url = URL(string: cover) else { return }
getData(from: url) { [weak self] image in
guard let self = self,
let downloadedImage = image else {
return
}
let artwork = MPMediaItemArtwork.init(boundsSize: downloadedImage.size, requestHandler: { _ -> UIImage in
return downloadedImage
})
self.nowplaying(with: artwork, artist: artist, song: song)
}
}
It would also save it temp to - which is inside the
class MusicPlayer {
struct NowPlaying: Codable, Identifiable {
var id: ObjectIdentifier
var artist : String
var song : String
var cover : String
}
//more code here
}
However I am getting two errors
Type 'MusicPlayer.NowPlaying' does not conform to protocol 'Decodable'
Type 'MusicPlayer.NowPlaying' does not conform to protocol 'Encodable'
Questions:
How do I make it to conform. - But we able to call it via Music.NowPlaying.
Is this the best way to do it, or can I access the MPMediaItemPropertyTitle in View?

UPDATE
Got the above error solved thanks to the comment below.
However am having issues fetching the data.
Type 'MusicPlayer.NowPlayingData.Type' cannot conform to 'Encodable'; only struct/enum/class types can conform to protocols
The code I used. - https://developer.apple.com/documentation/foundation/jsonencoder
let encoder = JSONEncoder()
encoder.outputFormatting = .prettyPrinted
let data = try encoder.encode(NowPlayingData)
print(String(data: data, encoding: .utf8)!)
To write it I placed
func getArtBoard(artist: String, song: String, cover: String) {
MusicPlayer.NowPlayingData(artist: artist, song: song, cover: cover)
}
DATA trying to encode
func getArtBoard(artist: String, song: String, cover: String) {
//MusicPlayer.NowPlayingData(artist: artist, song: song, cover: cover)
let pear = "{'artist':\(artist), 'song': \(song), 'cover':\(cover)}"
let encoder = JSONEncoder()
encoder.outputFormatting = .prettyPrinted
MusicPlayer.JN = try encoder.encode(pear)
