Date formatter crashes romanian language in Xcode - swift

Question

Below is the code to convert the string to date, which works perfectly for other languages but doesn't work when I change the iPad language to Romanian. Basically, it crashes when it finds it nil in the 5th line. But in English or any other language, this code perfectly converts to date.Any thought?
let dateOfProcedure = "03. Jun 2021 15:12:00"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd. MMM yyyy HH:mm:ss"
dateFormatter.timeZone = .current
let examDate = dateFormatter.date(from:dateOfProcedure)!

Answer 1

You need to set the locale for the formatter to one that matches the input. Assuming it is English you can use
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
Or use some other identifier where the language is English. Then if you want to convert it to another language you need a second formatter with the locale set to the language you want and use it to format a string from your Date object (examDate)
Below is a full example that parses the string and then format it into a Swedish date
let dateOfProcedure = "03. Jun 2021 15:12:00"
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.dateFormat = "dd. MMM yyyy HH:mm:ss"
dateFormatter.timeZone = .current
if let examDate = dateFormatter.date(from:dateOfProcedure) {
let outputFormatter = DateFormatter()
outputFormatter.locale = Locale(identifier: "sv_SE")
outputFormatter.dateStyle = .full
print(outputFormatter.string(from: examDate))
} else {
//Handle formatting error
}
