Current Week Start and End Date

Question

I want to get the current week start and end date and I also want to use the previous week start and end date and next week of the start and end date in current month.

Answer 1

Here is Swift 3 Version:-

extension Date {
    var startOfWeek: Date? {
        let gregorian = Calendar(identifier: .gregorian)
        guard let sunday = gregorian.date(from: gregorian.dateComponents([.yearForWeekOfYear, .weekOfYear], from: self)) else { return nil }
        return gregorian.date(byAdding: .day, value: 1, to: sunday)
    }

    var endOfWeek: Date? {
        let gregorian = Calendar(identifier: .gregorian)
        guard let sunday = gregorian.date(from: gregorian.dateComponents([.yearForWeekOfYear, .weekOfYear], from: self)) else { return nil }
        return gregorian.date(byAdding: .day, value: 7, to: sunday)
    }
}

You can get the week start date and end date like this :

let startWeek = Date().startOfWeek
let endWeek = Date().endOfWeek

print(startWeek ?? "not found start date")
print(endWeek ?? "not found end date")
