Swift 2 for loop low and high date between

问题:

I have Array ;

let startDate           = "2018-03-01"
let endDate             = "2018-03-03"

And I have 3 variable , startDate, endDate, dates , i want to append that variables, like;

if startDate = 2018-03-01, and endDate = 2018-03-03

will be add dates variable inside = "2018-03-01,2018-03-02,2018-03-03" between all dates from start and end dates.

Here is Solution for Print all dates between two Date (Swift 4 Code)

var mydates : [String] = []
let startDate = "2018-03-01"
let endDate   = "2018-03-05"

var dateFrom =  Date() // First date
var dateTo = Date()   // Last date

// Formatter for printing the date, adjust it according to your needs:
let fmt = DateFormatter()
fmt.dateFormat = "yyy-MM-dd"
dateFrom = fmt.date(from: startDate)!
dateTo = fmt.date(from: endDate)!


while dateFrom <= dateTo {
    mydates.append(fmt.string(from: dateFrom))
    dateFrom = Calendar.current.date(byAdding: .day, value: 1, to: dateFrom)!

}

print(mydates) // Your Result

Output is:

["2018-03-01", "2018-03-02", "2018-03-03", "2018-03-04", "2018-03-05"]
