Convert String date to Date doesn't work using dateFormatter and Swift

Question

This question is not a copy of another: I have an issue that I don't find somewhere else.

I want to convert a date as String to the Date format. This String date is supposed to be the same format as Date because I used to upload it as String in a database. Here is what the String date looks like:

"2017-03-10 22:16:00 +0000";

I'm trying to convert it like that:

    let df: DateFormatter = DateFormatter()

    df.dateFormat = "yyyy-MM-dd hh:mm:ss Z"

    print(beginDateString) // "2017-03-10 22:16:00 +0000"

    let beginDate = df.date(from: beginDateString)

    print(beginDate) // App crashs here because of nil value.

The issue is that it gives me a nil value for the variable beginDate. I also tried with other dateFormat like this one: "yyyy-MM-dd hh:mm:ss" but it still doesn't work.

I already tried this that's why this question IS NOT a dublicate! — Paul Bénéteau, Mar 07 '17 at 10:54
In addition, you should set the locale to "POSIX", see for example http://stackoverflow.com/questions/25657123/swift-nsdateformatter-not-working. — Martin R, Mar 07 '17 at 10:56
@greenpoisononeTV You will get date with format `yyyy-MM-dd HH:mm:ss Z` not the nil. — Nirav D, Mar 07 '17 at 10:59

Use yyyy-MM-dd HH:mm:ss Z not yyyy-MM-dd hh:mm:ss Z.

Because hh for hour in am/pm (1~12).

You also can do with: yyyy-MM-dd HH:mm:ss xxxx or yyyy-MM-dd HH:mm:ss XXXX, etc.

`hh is for (01-12)` – Leo Dabus Mar 07 '17 at 11:23

Try this...

let beginDateString: String = "2017-03-10 22:16:00 +0000"
let df: DateFormatter = DateFormatter()

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

if let beginDate = df.date(from: beginDateString)
{
    print(beginDate) 
}

And as @javimuu said you have to change your template.
