Date conversion from string not happening

Question

I have a date within order_date in this format May 31, 2018 at 3:35 PM

I’m converting it to Date like so…

if let order_date = value["order_date"] as? String {

let dateFormatter = DateFormatter()

dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"

let date = dateFormatter.date(from: order_date)

}

But I'm getting date as nil. What could be the issue..?

change your dateFormatter like this "MMMM dd, yyyy 'at' hh:mm a" — Jigar, Jun 01 '18 at 10:47
@FredericP I'm sending in this format..`yyyy-MM-dd HH:mm:ss`. But in the server, some dates are in this format `May 31, 2018 at 3:35 PM`. Hence the issue... — , Jun 01 '18 at 10:50
@Anbu.karthik Even if the format is `May 31, 2018 at 3:35 PM` I want it in this format...`yyyy-MM-dd HH:mm:ss.` — , Jun 01 '18 at 10:55
Look at your date string. Now look at your date format. They are nothing like each other. — Fogmeister, Jun 01 '18 at 11:02

your dateformat is wrong change your format to

dateFormatter.dateFormat = "MMMM dd, yyyy 'at' hh:mm a"

for e.g if you get the month as Mar then use - MMM, if you get March then use - MMMM

you can check the dateformat's in here

for full answer

 if let order_date = value["order_date"] as? String {

let dateFormatter = DateFormatter()
 dateFormatter.dateFormat = "MMMM dd, yyyy 'at' hh:mm a"
  var date = dateFormatter.date(from: order_date)
    if date == nil{
        dateFormatter.dateFormat =  "yyyy-MM-dd HH:mm:ss"
        date = dateFormatter.date(from: order_date)
    }
 dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
 let myStringafd = dateFormatter.string(from: date!)
 print(myStringafd)

}

.@Anbu.karthik `"MMM dd, yyyy 'at' hh:mm a"` won't be the format always. It could be `am` or `pm` – Jun 01 '18 at 10:48
But @Anbu.karthik isn't `"MMMM dd, yyyy 'at' hh:mm a"` always for A.M ? In my case it could be either AM or PM – Jun 01 '18 at 11:00
@bwv - based on the time format it will change AM or PM , its the 12 hour dateformat – Anbu.Karthik Jun 01 '18 at 11:05
.@Anbu.karthik In the answer that you gave, should we not give an if condition to check for the date format..? because the date that I'll get in `order_date ` can be either in the formats `"MMMM dd, yyyy 'at' hh:mm a"` or `"yyyy-MM-dd HH:mm:ss"` – Jun 01 '18 at 11:18
@bwv - check the updated answer – Anbu.Karthik Jun 01 '18 at 11:22
Ok @Anbu.karthik Thanks.. – Jun 01 '18 at 11:36

Replace your code with below :

if let order_date = value["order_date"] as? String
    {

        let dateFormatter = DateFormatter()

        dateFormatter.dateFormat = "MMM dd, yyyy 'at' hh:mm a"

        let date = dateFormatter.date(from: order_date)

    }
