在 XCode 模拟器上更改系统日期

Question

I'm trying to figure out how to specify a certain date on an XCode simulator, just like how you can simulate a location. I need to specify a date to test a sunrise/sunset calculation, which varies by date.

I see you can set a time zone environment variable in the build scheme like this .

Is it possible to set a specific date that way? If not, is there another way to set the date?

Answer 1

Numerous ways to create a Date object...

Here's one method using DateComponents -- which may work well for your testing:

    var dc = DateComponents()

    dc.year = 2022
    dc.month = 8
    dc.day = 25
    dc.hour = 12
    dc.minute = 34
    dc.second = 55

    let testDate = Calendar.current.date(from: dc)
