Get only time from Date

Question

How to get only time from the date with am/pm. Below is my code what I have tried so far:

func changeFormat(str:String) -> String {
    let dateFormatter = DateFormatter()
    let newDateFormatter = DateFormatter()
    
    // step 1
    dateFormatter.dateFormat = "MM/dd/yyyy HH:mm aa" // input format
    newDateFormatter.dateFormat = "HH:mm aa" // output format
    
    let date = dateFormatter.date(from: str)!

    // step 2
    
    let string = newDateFormatter.string(from: date)
    
    
    return string
}

Usage:

let strTimeFromDate = changeFormat(str: self.response?.Data[indexPath.row].ADateTime ?? "")

input date:

06/22/2021 2:00 PM

output:

12:45 PM

Getting wrong time return after formatting. Please guide what's wrong with above code

"HH" is for 24h format and "aa" is for 12h format so you can't mix them, so you should use "hh:mm a" instead for both DateTimeFormatter's
