does not conform to protocol Decodable / Codable

I'm using the following struct:

struct Item : Codable {

    var category:String
    var birthDate:Date
    var switch:Bool
    var weightNew: [Weight]
    var weightOld: Array<Double>
    var createdAt:Date
    var itemIdentifier:UUID
    var completed:Bool

    func saveItem() {
        DataManager.save(self, with: itemIdentifier.uuidString)
    }

    func deleteItem() { DataManager.delete(itemIdentifier.uuidString)
    }

    mutating func markAsCompleted() {
        self.completed = true
        DataManager.save(self, with: itemIdentifier.uuidString)
    }

}

And for weight:

struct Weight {
    var day:Int
    var weight:Double
    var type:Bool
}

After changing weightOld to weightNew I get two errors: - Type 'Item' does not conform to protocol 'Decodable' - Type 'Item' does not conform to protocol 'Codable'

If I leave out 'var weightNew: [Weight]' it works. Don't know what is happening and how to solve it... Help is appreciated.

Everything needs to be Codable. So far your Weight struct is not Codable. Update Weight to be Codable as well and then Item will be Codable.
