Find if the current date is between a weekly range - ios

Question

I have the following range:
Weekday Hour:Minute --> Weekday Hour:Minute
Weekday is an integer from 1 (Monday) to 7 (Sunday)
For example, a given range can be the following:
Monday 8:00 --> Friday 18:00
Saturday 10:00 --> Tuesday 10:00
Monday 10:00 --> Monday 20:00 (Just 10 hours on Monday)
Monday 20:00 --> Monday 10:00 (All week except Monday from 10:00 to 20:00)
I'm trying to find if the current date is in the selected range.
I tried multiple ways like creating NSDates from the ranges and comparing them but it still didn't pass all the tests.

Answer 1

You could do something like this:
First create the start and end dates from hour, minute and weekday. If start date results after end date go back to 1 week. Then compare the current date to start and end dates calculated to see if it is in range.
let currentDate = Date()
var startDate = dateBySetting(hour: 8, minute: 0, weekday: 1, of: currentDate)
let endDate = dateBySetting(hour: 9, minute: 0, weekday: 5, of: currentDate)
// If start date results after end date remove a week from the start
if startDate > endDate {
startDate = Calendar.current.date(byAdding: .weekOfYear, value: -1, to: startDate) ?? startDate
}
let dateIsInRange = startDate <= currentDate && currentDate <= endDate
func dateBySetting(hour: Int, minute: Int, weekday: Int, of date: Date) -> Date {
let calendar = Calendar.current
var date = calendar.date(bySettingHour: hour, minute: minute, second: 0, of: date) ?? date
date = calendar.date(bySetting: .weekday, value: weekday, of: date) ?? date
return date
}

Answer 2

It can be done using Calendar's nextDate function.
Eg: here I am checking if my current time falls in between Monday 8:00 --> Friday 18:00
//Monday 8:00 --> Friday 18:00
let currentDate = Date()
let calendar = Calendar.current
let yearComponent = (calendar.dateComponents(in: .current, from: Date()).year)!
let monthComponent = (calendar.dateComponents(in: .current, from: Date()).month)!
let previousTime = calendar.nextDate(after: currentDate,
matching: DateComponents(calendar: calendar, timeZone: .current, year: yearComponent, month: monthComponent, hour: 8, minute: 0, weekday: 2),
matchingPolicy: .strict,
repeatedTimePolicy: .first,
direction: .backward)
print(previousTime)
let nextTime = calendar.nextDate(after: previousTime!,
matching: DateComponents(calendar: calendar, timeZone: .current, year: yearComponent, month: monthComponent, hour: 18, minute: 0, weekday: 6),
matchingPolicy: .strict,
repeatedTimePolicy: .first,
direction: .forward)
print(nextTime)
print(currentDate > previousTime! && currentDate < nextTime!) //true

Answer 3

A solution is to use date components. Your last example Monday 20:00 --> Monday 10:00 is
let startComponents = DateComponents(hour:20, minute:0, weekday:1)
let endComponents = DateComponents(hour:10, minute:0, weekday:1)
Then get the next occurrence of the first components from the current date backward and the second forward
let now = Date()
let startDate = Calendar.current.nextDate(after: now, matching: startComponents, matchingPolicy: .nextTime, direction: .backward)!
let endDate = Calendar.current.nextDate(after: startDate , matching: endComponents, matchingPolicy: .nextTime)!
and create a DateInterval and check if the current date is in the range
let isInRange = DateInterval(start: startDate, end: endDate).contains(now)

Answer 4

extension Date {
func isSameWeek(as date: Date) -> Bool {
let dateComponents = Calendar.current.dateComponents([.day, .weekOfYear, .year], from: date)
let currentDateComponents = Calendar.current.dateComponents([.day, .weekOfYear, .year], from: self)
return dateComponents.year == currentDateComponents.year && dateComponents.weekOfYear == currentDateComponents.weekOfYear
}
}

Answer 5

you can try this extension:-
extension Date{
func timeAgoDisplay() -> String {
let secondsAgo = Int(Date().timeIntervalSince(self))
let minute = 60
let hour = minute * 60
let day = hour * 24
let week = day * 7
let month = week * 4
if secondsAgo < 60 {
return "\(secondsAgo) seconds ago"
}else if secondsAgo < hour {
return "\(secondsAgo/minute) minutes ago"
}else if secondsAgo < day {
return "\(secondsAgo/hour) hours ago"
}else if secondsAgo < week {
return "\(secondsAgo/day) days ago"
}else if secondsAgo < month {
return "\(secondsAgo/week) weeks ago"
}else {
return "\(secondsAgo/month) month(s) ago"
}
}
}
