How to write condition in struct-CodePudding

Based on condition, how to set Array of Dictionary else only Dictionary for struct.

   struct Data {
        let id: String?
        let name: String?
        let subData:  Environment.Dev == "Dev_URL" ? [SubData]? : SubData?
    
        init(_ json: JSON) {
            id = json["id"].stringValue
            name = json["name"].stringValue
            subData =  Environment.Dev == "Dev_URL" ? json["sub_data"].arrayValue.map { SubData($0) } : SubData(json["sub_data"])
        }
    }

// SubData Struct

   struct SubData {
        let id: String?
        init(_ json: JSON) {
            id = json["id"].stringValue
   }
}

My response structure changes due to environment changes.

How to set struct Data for let subData [SubData] i.e array of dictionary else SubData normal dictionary based on Dev or other.

CodePudding user response：

An easy way to make it array in both cases as type can't be determined at runtime

let subData:[SubData]?

Then

subData =  Environment.Dev == "Dev_URL"              
            ? json["sub_data"].arrayValue.map { SubData($0) }
            : [SubData(json["sub_data"])]

Also you can change your response sub_data to be an array in both cases so above line be

subData = json["sub_data"].arrayValue.map { SubData($0) }

That way you work in development and release smoothly
