I’ve a singleton class referred to as UserIDManager that generates a consumer id as a string and move it to some strategies and I’m utilizing it like this:

UserIDManager.shared.userID

I’ve one other class referred to as UserManager that passes userID to analytics. And this occurs when the app willEnterForegroundNotification

Now I have to subscribe to the userID within the init() of the consumer supervisor after which ship it to analytics each time it adjustments. I’m not accustomed to RxSwift very effectively, however on my take a look at undertaking, it is not going to replace or print any new id when getting into the foreground.

 UserIDManager.shared.rx
                   .observe(String.self, "userID")
                   .compactMap { $0 }
                   .distinctUntilChanged()
                   .subscribe(onNext: { userID in
                       self.userIDLabel.textual content = userID
                       print(userID)
                   })
                   .disposed(by: disposeBag)
