You can do this in following way...

// Saving logged info here Userdefault

let result = jsonDict["result"] as? NSDictionary ?? [:]

let data = try! NSKeyedArchiver.archivedData(withRootObject: result, requiringSecureCoding: false)
UserDefaults.standard.set(data, forKey: "currentUser")

// Get data from Userdefault

let result = UserDefaults.standard.data(forKey: "currentUser")
if result != nil{
    let dict = try! NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(result!) as? NSDictionary ?? [:]
    print("Current User Details : - \(dict)")
}
