List all Dates in current month in swift contains last month-CodePudding

I'm trying to list all Dates in the current month with this snipped

let now = Date()
let cal = Calendar.current
let monthRange = cal.range(of: .day, in: .month, for: now)!
let comps = cal.dateComponents([.year, .month], from: now)
var date = cal.date(from: comps)!

var dates: [Date] = []
for _ in monthRange {
    dates.append(date)
    date = cal.date(byAdding: .day, value: 1, to: date)!
}
print(">>>>>", dates)

But the output contains last month last day and also last day of the current month is not present.

CodePudding user response：

You only need to swap to line "dates.append(date)" & "date = cal.date(byAdding: .day, value: 1, to: date)!" into for loop

   func getDaysSimple(for month: Date) -> [Date] {
        
        //get the current Calendar for our calculations
        let cal = Calendar.current
        //get the days in the month as a range, e.g. 1..<32 for March
        let monthRange = cal.range(of: .day, in: .month, for: month)!
        //get first day of the month
        let comps = cal.dateComponents([.year, .month], from: month)
        //start with the first day
        //building a date from just a year and a month gets us day 1
        var date = cal.date(from: comps)!

        //somewhere to store our output
        var dates: [Date] = []
        //loop thru the days of the month
        for _ in monthRange {
            //add to our output array...
            date = cal.date(byAdding: .day, value: 1, to: date)!
            dates.append(date)
            //and increment the day
           
        }
        return dates
    }

print(getDaysSimple(for: .now))

then output come like this:-------
