Swift - replacement of INT with Date and comparison - ios

Question

I have this code:
let miesiacOd : 2017
let rokOd : Int = 10
let dzienOd : Int = 1
let dataOd = String(format: "%02d-%02d-%02d", rokOd, miesiacOd, dzienOd)
let miesiacDo : Int = 2018
let rokDo : Int = 10
let dzienDo : Int = 1
let dataDo = String(format: "%02d-%02d-%02d", rokDo, miesiacDo, dzienDo)
let dateFormatter2 = DateFormatter()
dateFormatter2.dateFormat = "yyyy-MM-dd"
I'm trying to compare it, but I have error. When converting variables to dates:
let dataDo2 = dateFormatter2.date(from: dataDo)
let dataOd2 = dateFormatter2.date(from: dataOd)
I have the date and time as a result. For example: 2017-10-01 +000
Why is this happening and how to fix it?
Finally, I would like to check if the current date is within the above dates.
I'm trying to do it like this:
let sprawdzamDostepnoscDat = Date().isBetweeen(date: dataOd2!, andDate: dataDo2!)
extension Date {
func isBetweeen(date date1: Date, andDate date2: Date) -> Bool {
return date1.timeIntervalSince1970 < self.timeIntervalSince1970 && date2.timeIntervalSince1970 > self.timeIntervalSince1970
}
}
Will this solution be ok?

Answer 1

You don't need a formatter (string parser) to create Date:
var dateFromComponents = DateComponents()
dateFromComponents.year = 2017
dateFromComponents.month = 10
dateFromComponents.day = 1
let dateFrom = Calendar.current.date(from: dateFromComponents)
var dateToComponents = DateComponents()
dateToComponents.year = 2018
dateToComponents.month = 10
dateToComponents.day = 1
let dateTo = Calendar.current.date(from: dateToComponents)
Also note that Date is already comparable, therefore your inBetween function can be just:
extension Date {
func isBetweeen(date date1: Date, andDate date2: Date) -> Bool {
return date1 <= self && self <= date2
}
}
However, if you want to ignore time and just compare the days, you should use:
extension Date {
func isBetweeen(date date1: Date, andDate date2: Date) -> Bool {
return Calendar.current.compare(date1, to: self, toGranularity: .day) != .orderedDescending
&& Calendar.current.compare(self, to: date2, toGranularity: .day) != .orderedDescending
}
}
