How to subtract 1 hour from current time using Swift?
To subtract hours from a date in swift we need to create a date first. Once that date is created we have to subtract hours from that, though swift does not provide a way to subtract date or time, but it provides us a way to add date or date component in negative value. In this example we’ll see how we can achieve the same.
Let’s create a date first, let it be today,
let today = Date()
Now to modify this date we’ll use the add function with negative value,
let modifiedDate = Calendar.current.date(byAdding: .hour, value: -2, to: today)!
Now to see the difference between both the dates, let’s add print statement for both of these. Our complete code should now look like this.
let today = Date() print(today) let modifiedDate = Calendar.current.date(byAdding: .hour, value: -2, to: today)! print(modifiedDate)
When we run the above code on a playground simulator we get the following result, which shows exactly a difference of two hours in both the date, and the modified date.
