how to avoid one number when the number is 00 in swift 4?

Question

I used the method for current time in my app But the problem is that when the 0 is behind a number the app won't print that like 10:23:4 as you see when the second is 04 the app won't print 04 and print 4 - I know that I can handle this with if else method But I want to know is it possible to fix that in codes or the only way is that? i know that I can use for loop But I want to use one line code to fix that because if use for loop I need to use that for hour and minutes too!

here is my codes

let date = Date()
    let calendar = Calendar.current

    let hour = calendar.component(.hour, from: date)
    let minutes = calendar.component(.minute, from: date)
    let seconds = calendar.component(.second, from: date)

    print("Time=\(hour):\(minutes):\(seconds)")

Please, just use a DateFormatter https://developer.apple.com/documentation/foundation/dateformatter — Wukerplank, Oct 09 '17 at 08:51
@Wukerplank exactly! Why are you not using a DateFormatter for this? — Fogmeister, Oct 09 '17 at 09:04
I know that Date Formatter is another way But I wanted to know how to use this and you can see the answer here below — Saeed Rahmatolahi, Oct 09 '17 at 09:05
@SaeedRahmatolahi DateFormatter is not "another way", it is the correct way to display date/time ;-) — Wukerplank, Oct 09 '17 at 11:35

Try this!

let date = Date()
let calendar = Calendar.current
let hour = calendar.component(.hour, from: date)
let minutes = calendar.component(.minute, from: date)
let seconds = calendar.component(.second, from: date)
let hourString = String.init(format: " %02d:%02d:%02d", hour,minutes,seconds)
print(hourString)

this method printed this ( 12:27: 0) so now there is space but still there is no 0 – Saeed Rahmatolahi Oct 09 '17 at 08:57
I updated my answer @SaeedRahmatolahi – Bhupat Bheda Oct 09 '17 at 09:01

This is a date. Use a DateFormatter. – Fogmeister Oct 09 '17 at 09:04
so I converted the hour - minute and second to persian format But the problem is that this method here will not work in that format I will ask another question please check that – Saeed Rahmatolahi Oct 09 '17 at 11:45
@SaeedRahmatolahi, if you would used `DateFormatter`, as several people already suggested you wouldn't have to create any new questions about hack-y ways to solve you problems. – user28434'mstep Oct 09 '17 at 13:34
please write answer DateFormatter and I will vote that answer – Saeed Rahmatolahi Oct 10 '17 at 05:13
