JSON Encoding / Decoding weird encoding of dictionary with enum values

Using Swift

Okay ! I already added a workaround by implementing the method in BuildingTemplate2, but since it has more than one property, It is a lot of code just for this...

struct BuildingTemplate: Encodable {
    let name: String
    let description: String
    
    let maxLife: Double
    let characteristics: [Characteristic: Double]
    let requiredToBuild: [Resource: Int]
    
    let skillsIds: [SkillId]
}

extension BuildingTemplate: Template {
    init(from decoder: Decoder) throws {
        let container = try decoder.container(keyedBy: BuildingTemplate.CodingKeys.self)
        
        self.name = try container.decode(String.self, forKey: .name)
        self.description = try container.decode(String.self, forKey: .description)
        self.maxLife = try container.decode(Double.self, forKey: .maxLife)
        let characteristicsDictionary = try container.decode([String: Double].self, forKey: .characteristics)
        self.characteristics = try characteristicsDictionary.map { tuple in
            guard let key = Characteristic(rawValue: tuple.key) else {
                throw DecodingError.valueNotFound(
                    Characteristic.self,
                    DecodingError.Context(codingPath: [BuildingTemplate.CodingKeys.characteristics], debugDescription: "unable to build an enum value with value provided : \(tuple.key)")
                )
            }
            return (key, tuple.value)
        }
        let requiredToBuildDictionary = try container.decode([String: Int].self, forKey: .requiredToBuild)
        self.requiredToBuild = try requiredToBuildDictionary.map { tuple in
            guard let key = Resource(rawValue: tuple.key) else {
                throw DecodingError.valueNotFound(
                    Resource.self,
                    DecodingError.Context(codingPath: [BuildingTemplate.CodingKeys.requiredToBuild], debugDescription: "unable to build an enum value with value provided : \(tuple.key)")
                )
            }
            return (key, tuple.value)
        }
        self.skillsIds = try container.decode([SkillId].self, forKey: .skillsIds)
    }
}
