Swift Codable protocol… encoding / decoding NSCoding classes -

i have following struct…

struct photo: codable {      let hasshadow: bool     let image: uiimage?      enum codingkeys: string, codingkey {         case `self`, hasshadow, image     }      init(hasshadow: bool, image: uiimage?) {         self.hasshadow = hasshadow         self.image = image     }      init(from decoder: decoder) throws {         let container = try decoder.container(keyedby: codingkeys.self)         hasshadow = try container.decode(bool.self, forkey: .hasshadow)          // fails         image = try container.decode(uiimage?.self, forkey: .image)      }      func encode(to encoder: encoder) throws {         var container = encoder.container(keyedby: codingkeys.self)         try container.encode(hasshadow, forkey: .hasshadow)          // fails         try container.encode(image, forkey: .image)     } } 

encoding photo fails …

optional not conform encodable because uiimage not conform encodable

decoding fails with…

key not found when expecting non-optional type optional coding key \"image\""))

is there way encode swift objects include nsobject subclass properties conform nscoding (uiimage, uicolor, etc)?

thanks @vadian pointing me in direction of encoding/decoding data…
