How to Clear Shared Dictionary which is causing saved values not to clear even when I login with other user - swift

Question

How can I clear the shared dictionary on logout in which I am saving login response?
Here is the code I am doing on getting status 1.
if(status == 1)
{
DispatchQueue.main.async {
GAReusableClass.sharedInstance.hideActivityIndicator()
UserDefaults.standard.set(self.DataDict, forKey:MaindataKey)
let Dict = self.mainDict[KData] as! [String: AnyObject]
print("self.DataDict", self.DataDict)
let User_ID = Dict[KUuid]as! String
print(User_ID)
let HMACSECRETKEY = self.deviceToken + "+" + User_ID
kHMACKey = HMACSECRETKEY
let cipher:String = CryptoHelper.encrypt(input:HMACSECRETKEY)!;
print(HMACSECRETKEY)
UserDefaults.standard.setValue(cipher, forKey:HmacKey)
UserDefaults.standard.set(true, forKey: "isLogin")
GAloginUserInfo.shared.saveUserInfo(dict: Dict )
let tabar = self.storyboard?.instantiateViewController(withIdentifier: "GAtHomeTabbarViewController") as! GAtHomeTabbarViewController
self.navigationController?.pushViewController(tabar, animated: true)
}
Here is the shared dictionary which I am using to save the values of login response.
import UIKit
import Firebase
class GAloginUserInfo: NSObject {
var loginUserMobileNo : String?
var loginUserId : String?
var loginUserUuid : String?
var loginUserCountry : String?
var loginUserCountryCode : String?
var loginUserEmail : String?
var loginUserlatitude : String?
var loginUserLongitude : String?
var loginUserName : String?
var loginUserQrcode : String?
var loginUserProfilePic : String?
var isverify : String?
var loginPassword : String?
var dateOfBirth: String?
var earnedPoints:String?
var loginUserGender:String?
var loginUserFollowers:Int = 0
static let shared = GAloginUserInfo()
func saveUserInfo (dict : [String : AnyObject?] ) {
if let loginUserMobileNo = dict["mobile"] as? String {
self.loginUserMobileNo = loginUserMobileNo
}
if let loginUserId = dict["id"] as? String {
self.loginUserId = loginUserId
}
if let loginUserUuid = dict["uuid"] as? String {
self.loginUserUuid = loginUserUuid
print(loginUserUuid)
}
if let loginUserCountry = dict["country"] as? String {
self.loginUserCountry = loginUserCountry
}
if let loginUserCountryCode = dict["country_code"] as? String {
self.loginUserCountryCode = loginUserCountryCode
}
if let loginUserEmail = dict["email"] as? String {
self.loginUserEmail = loginUserEmail
}
if let loginUserProfilePic = dict["profile_pic"] as? String {
self.loginUserProfilePic = loginUserProfilePic
}
if let loginUserLongitude = dict["logitude"] as? String {
self.loginUserLongitude = loginUserLongitude
}
if let loginUserName = dict["name"] as? String {
self.loginUserName = loginUserName
}
if let loginUserQrcode = dict["qr_code"] as? String {
self.loginUserQrcode = loginUserQrcode
}
if let Password = dict["password"] as? String{
self.loginPassword = Password
}
if let dateOfBirth = dict["dob"] as? String{
self.dateOfBirth = dateOfBirth
}
if let earnedPoints = dict["points"] as? String{
let myDouble = Double(earnedPoints)
let doubleStr = String(format: "%.2f", myDouble!)
self.earnedPoints = doubleStr
}
if let loginUserGender = dict["gender"] as? String{
self.loginUserGender = loginUserGender
}
if let loginUserFollowers = dict["followersCount"] as? Int{
self.loginUserFollowers = loginUserFollowers
}
}
}
Actually, the problem is when I log out and log in again with some other user it still shows some values of the previous user. I am clearing the userdefaults on the logout function. but I don't know how to clear this type of shared dictionary.

Use removeObject(forKey:)
to remove the values stored from user defaults in Logout method
UserDefaults.standard.removeObject(forKey: MaindataKey)
UserDefaults.standard.removeObject(forKey: HmacKey)
UserDefaults.standard.set(false, forKey: "isLogin")
Create a method to remove the values from the singleton class like this
extension GAloginUserInfo {
func removeUserInfo() {
self.loginUserMobileNo = nil
self.loginUserId = nil
self.loginUserUuid = nil
self.loginUserCountry = nil
self.loginUserCountryCode = nil
self.loginUserEmail = nil
self.loginUserlatitude = nil
self.loginUserLongitude = nil
self.loginUserName = nil
self.loginUserQrcode = nil
self.loginUserProfilePic = nil
self.isverify = nil
self.loginPassword = nil
self.dateOfBirth = nil
self.earnedPoints = nil
self.loginUserGender = nil
self.loginUserFollowers = 0
}
}
and call this method in logout
GAloginUserInfo.shared.removeUserInfo()
