Answer 1

Calendar units should be thought of as intervals. As of iOS 10 Calendar has some nice methods for this

let day = Calendar.autoupdatingCurrent.dateInterval(of: .day, for: Date())
day?.end
day?.start

You can use the same method, to get the start/end of any calendar component (week/month/year etc)
