                if let prayTime = dataT?["times"] as? NSArray  {
                    if let fajerTT = prayTime[0] as? String {         
                      let timeFormat = DateFormatter()
                       timeFormat.dateFormat = "hh:mm"
                        let timeFajer=timeFormat.date(from: fajerTT)
                      print(fajerTT)
                       print("\(timeFajer))")
                   self.fajerT.text=timeFajer
                    }else {print("false")}
                 }

            }catch{print("Error")

If you want to compare the times in the received array with the current time you don't need to convert the dates to 12 hour format.

Get the date components and compare it with the current date.

Basically your date format is wrong. Since the times are in 24 hour format it's HH:mm.

Example

let timeFormatter = DateFormatter()
timeFormatter.dateFormat = "HH:mm"
let outputFormatter = DateFormatter()
outputFormatter.dateFormat = "hh:mm a"
let calendar = Calendar.current
let now = Date()

let times = ["05:05","06:30","12:56","16:30","19:21","19:21","20:51"]
for time in times {
    let date = timeFormatter.date(from: time)!
    let components = calendar.dateComponents([.hour, .minute], from: date)
    let match = calendar.date(now, matchesComponents: components)
    print(match)
    let output = outputFormatter.string(from: date)
    print(output)
}

And – as usual – do not use Foundation collection types (NSArray/NSDictionary) in Swift, use native types and never pass the option .mutableContainers

   if let dataT = try JSONSerialization.jsonObject(with: data!) as? [String:Any],
      let prayTime = dataT["times"] as? [[String:Any]]  {

thank you for your answer but i need to convert to 12 hours because i need use to put in ui for user — Khaled Jano, Aug 29 '17 at 20:58
