In my case, I’m working on a csv importer and I wanted to get from the system the decimal and thousand delimiters.
This is the way I do it, a workaround sure but works great:
var thousandDelimiter = NSNumberFormatter.localizedStringFromNumber(NSNumber(double: 1234), numberStyle: NSNumberFormatterStyle.DecimalStyle)
thousandDelimiter = thousandDelimiter.substringWithRange(thousandDelimiter.startIndex.advancedBy(1)…thousandDelimiter.startIndex.advancedBy(1))
var commaDelimiter = NSNumberFormatter.localizedStringFromNumber(NSNumber(double: 1.02), numberStyle: NSNumberFormatterStyle.DecimalStyle)
commaDelimiter = commaDelimiter.substringWithRange(commaDelimiter.startIndex.advancedBy(1)…commaDelimiter.startIndex.advancedBy(1))
Again, documentation in this case is quite good, find more here.
