Usually we use DateFormatter to parse and format dates. Try this code.

let inputDateString = "Fri, 16 Aug 2019 07:04:12 +0000"

let formatter = DateFormatter()
formatter.dateFormat = "E, d MMM yyyy HH:mm:ss Z"
formatter.timeZone = TimeZone(secondsFromGMT: 0)

let inputDate = formatter.date(from: inputDateString)

let germanDateFormatter = DateFormatter()
germanDateFormatter.dateFormat = "d.M.yyyy HH:mm:ss"
germanDateFormatter.timeZone = TimeZone(secondsFromGMT: 0)

if let date = inputDate {

    let result = germanDateFormatter.string(from: date)

    print(result) //16.8.2019 07:04:12
}

Also you can use this service to find common date formats https://nsdateformatter.com

As suggested in comments you can use Locale to format the date according to the user Locale. But you will get a bit another format then you need.

let inputDateString = "Fri, 16 Aug 2019 07:04:12 +0000"

let formatter = DateFormatter()
formatter.dateFormat = "E, d MMM yyyy HH:mm:ss Z"
formatter.timeZone = TimeZone(secondsFromGMT: 0)

let inputDate = formatter.date(from: inputDateString)

let germanDateFormatter = DateFormatter()
germanDateFormatter.locale = .init(identifier: "de")
germanDateFormatter.dateStyle = .short
germanDateFormatter.timeStyle = .medium
germanDateFormatter.timeZone = TimeZone(secondsFromGMT: 0)

if let date = inputDate {

    let result = germanDateFormatter.string(from: date)

    print(result) //16.08.19, 07:04:12
}
