getting win - loss counter to save in user default swift - ios

Question

I am comparing whether a user should get a win or loss in their score column. I can't get the code to store the win/loss and then add 1 on top of it every time the if statement runs. Here is my if statement, followed by where i call it in the view did load. Cant seem to figure where I'm going wrong. thanks for the help!
viewDidLoad {
let dailyWinsDefault = UserDefaults.standard.integer(forKey: "dailyWinsDefault")
winsLabel.text = "\(dailyWinsDefault)"
print(dailyWinsDefault)
let dailyLossDefault = UserDefaults.standard.integer(forKey: "dailyLossDefault")
lossLabel.text = "\(dailyLossDefault)"
print(dailyLossDefault)
}
showWinLossVC.callbackForWinLoss = { result in
if result > 0.0 {
self.dailyWins += 1
UserDefaults.standard.set(self.dailyWins, forKey: "dailyWinsDefault")
self.winsLabel.text = String(self.dailyWins)
print(self.dailyWins)
}
else if result < 0.0 {
self.dailyLosses += 1
UserDefaults.standard.set(self.dailyLosses, forKey: "dailyLossDefault")
self.lossLabel.text = "\(self.dailyLosses)"

Answer 1

Couple of mistakes
Mistake 1:
Seems like you are setting integer in UserDefault for key dailyWinsDefault using statement
UserDefaults.standard.set(self.dailyWins, forKey: "dailyWinsDefault")
And you expect it to return you String when you retrieve it with
if let dailyWinsDefault = UserDefaults.standard.string(forKey: dailyWinsDefault)
Why will it not return nil ?
use
let dailyWinsDefault = UserDefaults.standard.integer(forKey: "dailyWinsDefault")
Mistake 2:
In your statement
if let dailyWinsDefault = UserDefaults.standard.string(forKey: dailyWinsDefault)
dont you think dailyWinsDefault should be in double quote as its a key and supposed to be string ?
try
let dailyWinsDefault = UserDefaults.standard.integer(forKey: "dailyWinsDefault")
EDIT:
As OP has updated code and now facing a issue with his updated code and requested for help updating my answer.
Couple of issues again
Mistake 1:
In entire ViewDidLoad method u never assigned the value retried from user defaults to property dailyWins and dailyLoses
viewDidLoad {
let dailyWinsDefault = UserDefaults.standard.integer(forKey: "dailyWinsDefault")
self.dailyWins = dailyWinsDefault //this is missing
winsLabel.text = "(dailyWinsDefault)"
print(dailyWinsDefault)
let dailyLossDefault = UserDefaults.standard.integer(forKey: "dailyLossDefault")
self.dailyLosses = dailyLossDefault //this is missing
lossLabel.text = "\(dailyLossDefault)"
print(dailyLossDefault)
}
Mistake 2:
Though not specific to your problem, you should always call super.viewDidLoad in your viewDidLoad unless u have a very firm reason for not doing so
That should help :)
