ios – Swift: getting error whereas decoding utilizing CodingKey

I’ve created a mannequin and I must attempt to add worth to one of many CodingKey‘s case

struct Mannequin {

  let descriptions: String

}
    
enum CodingKeys: String, CodingKey {

  case descriptions = "INFO-(NSLocalizedString("Language", remark: ""))"
    
}
    
init(from decoder: Decoder) throws {

  let container = attempt decoder.container(keyedBy: CodingKeys.self)
  descriptions = attempt container.decode(String.self, forKey: .descriptions)
        
}

Now compiler provides me this error

🛑 Uncooked worth for enum case have to be a literal

How can I repair this error?

Edited:

Decoding:

remaining class ModelData: ObservableObject {
    @Printed var dinosaurs: [String:Model] = load("information.plist")
}

func load<T: Decodable>(_ filename: String) -> T {
    let information: Knowledge
    
    guard let file = Bundle.essential.url(forResource: filename, withExtension: nil)
    else {
        fatalError("Could not discover (filename) in essential bundle.")
    }
    
do {
    information = attempt Knowledge(contentsOf: file)
} catch {
    fatalError("Could not load (filename) from essential bundle:n(error)")
}

do {
    let decoder = PropertyListDecoder()
    return attempt decoder.decode(T.self, from: information)
} catch {
    fatalError("Could not parse (filename) as (T.self):n(error)")
}

}
