        channelId <- map["channel_id"]
        msgCount <- map["msg_count"]
        mentionCount <- map["mention_count"]
 }

to

mutating func mapping(map: Map) {
        teamId         <- map["team_id"]
        channelId      <- map["channel_id"]
        msgCount       <- map["msg_count"]
        mentionCount   <- map["mention_count"]
