Show AM/PM in capitals in swift

I wrote the following code to show a datetime in a particular format:

let formatter = NSDateFormatter()
formatter.dateStyle = NSDateFormatterStyle.LongStyle
formatter.timeStyle = .MediumStyle
formatter.dateFormat = "HH:mm a 'on' MMMM dd, yyyy"
let dateString = formatter.stringFromDate(newDate!)
println(dateString)

Output

12:16 pm on July 17, 2015

I want to show 'pm' as 'PM'(in capitals) and if phone has 24 hours format then AM/PM should not appear. Please help me.

Solution

  • You can set your DateFormatter amSymbol and pmSymbol as follow:

    Xcode 8.3 • Swift 3.1

    let formatter = DateFormatter()
formatter.locale = Locale(identifier: "en_US_POSIX")
formatter.dateFormat = "h:mm a 'on' MMMM dd, yyyy"
formatter.amSymbol = "AM"
formatter.pmSymbol = "PM"

let dateString = formatter.string(from: Date())
print(dateString)   // "4:44 PM on June 23, 2016\n"
