//Decoding example. Convert an ISO8601 to Date()
let decoder = JSONDecoder()
decoder.dateDecodingStrategy = .iso8601

//Custom: You can also decode from a custom date format using DateFormatter().
decoder.dateDecodingStrategy = .formatted(someCustomDateFormatter)

//You can also decode with a closure
decoder.dateDecodingStrategy = .custom { decoder in
