Convert string time into date swift - swift

Question

I have json from rest API :
{
"status": "ok",
"query": {
"format": "json",
"kota": "703",
"tanggal": "2017-02-07"
},
"jadwal": {
"status": "ok",
"data": {
"ashar": "15:26",
"dhuha": "06:21",
"dzuhur": "12:10",
"imsak": "04:28",
"isya": "19:31",
"maghrib": "18:20",
"subuh": "04:38",
"tanggal": "Selasa, 07 Feb 2017",
"terbit": "05:54"
}
}
}
I want convert jadwal -> data -> ashar and other into Date format
I have this code,
extension String {
func convertToDate() -> Date? {
let arr = self.split(separator: ":")
guard
let hour = Int(arr.first ?? ""),
let minute = Int(arr.last ?? "")
else { return nil }
let component = DateComponents(hour: hour, minute: minute)
var cal = Calendar.current
guard let timezone = TimeZone(identifier: "Asia/Jakarta") else { return nil }
cal.timeZone = timezone
let date = cal.date(from: component)
return date
}
}
But i get this result on my console debug
ashar: 0001-01-01 08:27:48 +0000
i expect for example on asr/ashar = 2021-01-12 15:26:00 for Indonesia Time, do you guys have advice or something?

Answer 1

You can create an extension for string that returns a full date object by passing only the time string as follows.
extension String {
func createDateObjectWithTime(format: String = "HH:mm") -> Date? {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = format
guard let dateObjectWithTime = dateFormatter.date(from: self) else { return nil }
let gregorian = Calendar(identifier: .gregorian)
let now = Date()
let components: Set<Calendar.Component> = [.year, .month, .day, .hour, .minute, .second]
var dateComponents = gregorian.dateComponents(components, from: now)
let calendar = Calendar.current
dateComponents.hour = calendar.component(.hour, from: dateObjectWithTime)
dateComponents.minute = calendar.component(.minute, from: dateObjectWithTime)
dateComponents.second = 0
return gregorian.date(from: dateComponents)
}
}
You can call the extension by:
let date = "15:26".createDateObjectWithTime()

Just get the current date and set hour and minute to the extracted values
extension String {
func convertToDate() -> Date? {
let arr = self.split(separator: ":")
guard
let hour = Int(arr.first ?? ""),
let minute = Int(arr.last ?? "")
else { return nil }
var cal = Calendar.current
guard let timezone = TimeZone(identifier: "Asia/Jakarta") else { return nil }
cal.timeZone = timezone
return cal.date(bySettingHour: hour, minute: minute, second: 0, of: Date())
}
}
