let dateTest = time2.timeIntervalSince1970-time1.timeIntervalSince1970Then I tried to use time2.timeIntervalSince(date: time1), but the result milliseconds again far exceeded the actual Time.
How can I get the correct time difference twice and get the hour and minute results in the format "0823" of 8 hours and 23 minutes?
let difference = Calendar.current.dateComponents([.hour, .minute], from: time1, to: time2)
let formattedString = String(format: "%02ld%02ld", difference.hour!, difference.minute!)
print(formattedString)
Format? ld adds padding with zeros.
If you need a standard format, use a colon between hours and minutes, DateComponentsFormatter() may be a more convenient way
let formatter = DateComponentsFormatter()
formatter.allowedUnits = [.hour, .minute]
print(formatter.string(from: time1, to: time2)!)

I have 2 variables, I get 2 times from datePicker, I need to save the difference between them on the variable.
let timeFormatter = DateFormatter()
timeFormatter.dateFormat = "HHmm"
time2 = timeFormatter.date(from: timeFormatter.string(from: datePicker.date))!
I tried to get timeIntervalSince1970 from both of them and they subtracted them and got the difference in milliseconds, I will go back to hours and minutes, but I get a very large number, which does not correspond to the actual time.
let dateTest = time2.timeIntervalSince1970-time1.timeIntervalSince1970
Then I tried to use time2.timeIntervalSince(date: time1), but the milliseconds again far exceeded the actual time.

The recommended method for any date math is Calendar and DateComponents
let difference = Calendar. current.dateComponents([.hour, .minute], from: time1, to: time2)
let formattedString = String(format: "%02ld%02ld", difference.hour!, difference.minute!)
print(formattedString)

formatter.allowedUnits = [.hour, .minute]
print(formatter.string(from: time1, to: time2)!)
