How to parse JSON with Decodable when JSON has a String with "-" in its name

Question

So I was trying JSON parsing with Decodable and the fields of the Decodable struct should match with their names in JSON but there's an object in JSON which has a "-" in its name. How do I name the field in the Struct?

JSON:

"media-metadata": [
    {
        "format": "Standard Thumbnail",
        "height": 75,
        "width": 75
    },
    {
        "format": "mediumThreeByTwo440",
        "height": 293,
        "width": 440
    }
]

Code:

struct  MediaMetadataDetails: Decodable {
    let format: String
    let height: Int
    let width: Int
}

struct MediaObject: Decodable {
    let media-metadata: [MediaMetadataDetails] // ???
}

You need to add CodingKeys enum

struct MediaObject: Decodable {
    let mediaMetadata: [MediaMetadataDetails] 
    enum CodingKeys: String, CodingKey {
       case mediaMetadata = "media-metadata" 
    }
}
