My question is how to take this code:

Code Block var now = Date()

And get the beginning of that date. Let's say that Date() return March 17, 2021, 9 pm: 47 : 32 . How would you take that and get March 17, 2021, 12 am : 00 : 00?

Also, my aim is to get code that works in SwiftUI because every other online forum I searched had out dated results for UIkit or Swift 3.

Thank you,
Rorocoder

this maybe of use:

Code Block         let now = Date()
        let startOfDay = Calendar.current.startOfDay(for: now)
        print("startOfDay: \(startOfDay)")

You can format the date, like:

Code Block         let formatter = DateFormatter()
        formatter.dateStyle = .full
        formatter.timeStyle = .medium
        print(" now: \(formatter.string(from: now)) \n startOfDay: \(formatter.string(from: startOfDay))")

Thank you, but when I try and put startOfDay into a Core Data Fetch Request as a Predicate format I get an error saying something about can't use initializers. Do you know how to solve this. Thank you so much for your help already.

glad it helped. As for the Core Data Fetch Request question, show us the code you are using.

This shouldn't be tagged with "SwiftUI". The Date type is in Foundation and the answer will be the same regardless of whether the app is using SwiftUI, AppKit, UIKit, or the command line.
