Swift 3 Easy way to truncate Date to start of the day/month/year

Question

Is there any easy way to truncate date like we can do in Oracle Database? For example, I need to set value starting from midnight. In Oracle I can do TRUNC(SYSDATE). But I canno

Answer 1

Note the +0000 at the end of the time in your sample.

The start of the day where? I updated the sample to show what you want.

var comp: DateComponents = Calendar.current.dateComponents([.year, .month, .day], from: Date())
comp.timeZone = TimeZone(abbreviation: "UTC")!
let truncated = Calendar.current.date(from: comp)!
print(truncated)

It prints 2017-06-14 00:00:00 +0000. Again, note the +0000 at the end.

By default the timezone is set to be the current timezone and the hour, minute, and second are 0 in that timezone.

I will assume that you want the current timezone. With that stipulation, your code is correct.
