I have an API that returns data including a timestamp for that record. In swift I have the timestamp element loaded and converted into a double and can then convert that into time. I want to be able to return the time if the date of the record is today and return the date if the record is not today. See below: let unixTimeString:Double = Double(rowData["Timestamp"] as! String)! let date = NSDate(timeIntervalSince1970: unixTimeString) // This is on EST time and has not yet been localised. var dateFormatter = NSDateFormatter() dateFormatter.timeStyle = .ShortStyle dateFormatter

Closed. This question is off-topic . It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . How can I find the count of a specific weekday occurring between two NSDates ? I have searched for quite a while but came up with only solution in which number of total weekdays have been counted, not only the one specific week day. The idea of the following code is to compute the first occurrence of the given weekday after the start date, and then compute the number of weeks remaining to the end date. NSDate

I'm having trouble here. Took me hours but no use. Please keep in mind I checked the heck of StackOverFlow for a fix but there isn't any. When I convert the _date Object from Gregorian to Hijri it does not convert. I know that because when I print it it still gives me the Gregorian day. This troubles me because I want to setDate of a UIDatePicker and it's setting it incorrectly because the _date is gregorian and my UIDatePicker object calendar set to setCalendar:_hijriCalendar //DATE SETTING _date = [NSDate date]; _hijriCalendar = [[NSCalendar alloc]initWithCalendarIdentifier:NSIslamicCalendar

I'm trying to work with dates and create dates in the future, but daylight savings keeps getting in the way and messing up my times. Here is my code to move to midnight of the first day of the next month for a date: + (NSDate *)firstDayOfNextMonthForDate:(NSDate*)date { NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; calendar.timeZone = [NSTimeZone systemTimeZone]; calendar.locale = [NSLocale currentLocale]; NSDate *currentDate = [NSDate dateByAddingMonths:1 toDate:date]; NSDateComponents *components = [calendar components:NSYearCalendarUnit |

As today is Friday , which is 6 according to NSCalendar . I can get this by using the following Calendar.current.component(.weekday, from: Date()) How do I get weekday component of Saturday last week, which should be 7 ? If I do Calendar.current.component(.weekday, from: Date()) - 6 . I am getting 0 which is not valid component. Tj3n Try this, you have to get the date first then subtract again from it: var dayComp = DateComponents(day: -6) let date = Calendar.current.date(byAdding: dayComp, to: Date()) Calendar.current.component(.weekday, from: date!) For that first you need to get that date
