How to get 1 hour ago from a date in iOS swift?

Question

I have been researching, but I couldnt find exact solution for my problem. I have been trying to get 1 hour ago from a date. How can I achieve this in swift?

Answer 1

Please read the NSDate class reference.

let oneHourAgo = NSDate.dateWithTimeIntervalSinceNow(-3600)

should do it.

Or, for any NSDate object:

let oneHourBack = myDate.dateByAddingTimeInterval(-3600)

Swift 4:

let oneHourAgo = NSDate(timeIntervalSinceNow: -3600)
