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)
}
}
}
}
}

Step1: Prepare your model as shown in below code snippet.
class Addresses: NSObject {
var default = 0
var number = 0
var name = String()
var address = String()
init?(dictionary:[String:Any]) {
guard let default = dictionary["default"],
let number = dictionary["number"],
let name = dictionary["name"],
let address = dictionary["address"]
else {
return nil
}
self.default = default
self.number = number
self.name = name
self.address = address
}
}
Step2: Declare an array to store parsed addresses.
var addressesArray = [Addresses]()
Step3:
if let addressArray = jsonObj!.value(forKey: "address") as? NSArray{
for array in addressArray {
if let addressDict = array as? NSDictionary{
if let defaultValue = addressDict.value(forKey: "default") as? Int{
if defaultValue == 1 {
if let address = Addresses(dictionary: addressDict) {
addressesArray.append(address)
}
}
}
}
}
}
Thats it, take care of datatypes, and you can use addressesArray to display data.
