You can also change the time in your code.

You change your specific date to your current date.

Thank for the answer, but, how i can pass my current date (generated in code) to preview?

Example:

Code Block struct DemoView_Previews: PreviewProvider {
  static var previews: some View {
    let myCustomDate = Date() // just for example
      return DemoView()
  }
}

How i can pass myCustomDate to DemoView as System Date?

May be my english is poor to explain..

i know how to pass a var to my view, for init, or binding, or environmentObject... I want pass a date for preview simulator... so when run my view in the preview the simulator's date will be that date.
