I am trying to figure out how to reset a label in an app after every 7 days even though the user launches the app on the 8th day.

To simplify the approach I have a label with a string set to it in ViewDidLoad. 

override func viewDidLoad() {
    super.viewDidLoad()

    self.nameLabel.text = "Today"

    // Check for the current day
    let date = Date()
    let formatter  = DateFormatter()
    formatter.dateFormat = "EEEE"
    let WeekDay = formatter.string(from: date)
}

I can check for which day it is but is there a way to ensure I save the day and then check if the day has passed Sunday to then change the label to something else?

Thanks in advance.

    Just save the date to UserDefaults and next time your app starts just get the date components `[.day]` from the saved date to today's date and check if it is greater than 7 if not save it again to UserDefaults – Leo Dabus Sep 21 '16 at 19:38
  • I see. Do you mind posting the code. Apologies I am little new to user defaults and how they work. – Gugulethu Sep 21 '16 at 19:44
  • Sorry man, I don't mind posting the code but SO it is not a code writing service, I gave you all you need to accomplish that. First you need to try it your self and post another question with your attempt and whats not working. I can help you in every step but I won't lift you straight there. – Leo Dabus Sep 21 '16 at 19:52
