`Calendar.current.startOfDay(for: self)` rounds to the hour, not the day.

let date = Date()
let rounded = Calendar.current.startOfDay(for: date)
print("Round \(date) to \(rounded)")

iOS          output: `Round 2023-12-15 19:06:55 +0000 to 2023-12-15 07:00:00 +0000` (The 7 is the timezone I'm in)
Skip Android output: `Round 2023-12-15 19:06:55 +0000 to 2023-12-15 19:00:00 +0000` (only rounds to nearest hour)

Looks like

Calendar.current.date(from: Calendar.current.dateComponents([.year, .month, .day], from: self)) is a functional workaround for rounding to day.
