Xcode – Swift – If time ago is more then x minutes

So I have a date like this:

let date = Date()

Lets say that the date is 12.08.2021 14:40. I want to check and do stuff if there is more then 25 minutes past that date. How can I do this?

    You can use timeIntervalSinceNow and measure the difference (in seconds)

    let previousDate = Date().advanced(by: -1000)
print("previous: (previousDate)")

if -previousDate.timeIntervalSinceNow > 25 * 60 {
    print("past 25 minutes")
} else {
    print("not past 25 minutes")
}

    This example is relative, so will always print "not past 25 minutes" – however previousDate would be the actual previous date.

    The below function will allow you to check if the elapsed time since a previous date is more than a specific number of minutes.

    func intervalSince(_ previous: Date, isMoreThan minutes: Int) -> Bool {
   return Date() > previous.advanced(by: Double(minutes) * 60.0)
}

    Note: This method only works with iOS 13 and above.

    I made this function. you use date.timeAgoSince(). This confirms how many minutes ago your variable was.

    
  extension Date {
        func timeAgoSince() -> String {
        
            let calendar = Calendar.current
            let now = Date().datePickerToString().stringToDate()
            let unitFlags: NSCalendar.Unit = [.second, .minute, .hour, .day, .weekOfYear, .month, .year]
            let components = (calendar as NSCalendar).components(unitFlags, from: self, to: now, options: [])

            if let minute = components.minute, minute >= 1 {
                return "past (minute) minutes"
            }

            return "now"
}
