You can check if Default equals 1 and add those values to an array.

var defaultArray = [NSDictionary]()
if let addressArray = jsonObj!.value(forKey: "address") as? NSArray{
                    for array in addressArray {
                        if let addressDict = array as? NSDictionary{
                            if let Default = addressDict.value(forKey: "default"){
                               if Default == 1 {
                               defaultArray.append(addressDict)
                              }
                            }
                        }
                    }
                }
