How to extract today, yesterday from Date() and make it localised like weekday and months?

I want to extract today, yesterday from date so it is localised automatically when I change language like which happens with weekdays and month.

Code for localised date that I am using: 

let dateFormatter = Foundation.DateFormatter()
dateFormatter.dateFormat = "MMMM dd, yyyy"
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.timeZone = TimeZone(identifier: "UTC")
let dateStr = dateFormatter.string(from: datePickerView.date)
let timeStr = "00:00:00.000"

let dateString = NSString(format:"%@ %@",dateStr,timeStr)
let mainDF = Foundation.DateFormatter()
mainDF.dateFormat = "MMMM dd, yyyy hh:mm:ss.SSS"
mainDF.locale = Locale(identifier: "en_US_POSIX")
mainDF.timeZone = TimeZone(identifier: "UTC")
let date = mainDF.date(from: dateString as String)

How to achieve this?

DateFormatter has special flag for that: doesRelativeDateFormatting, which renders dates in relative format, using locale set for this formatter.

… If a date formatter uses relative date formatting, where possible it replaces the date component of its output with a phrase—such as “today” or “tomorrow”—that indicates a relative date. The available phrases depend on the locale for the date formatter; whereas, for dates in the future, English may only allow “tomorrow,” French may allow “the day after the day after tomorrow,” …

Example:

let dateFormatter = DateFormatter()
dateFormatter.locale = Locale.autoupdatingCurrent // Using system locale
dateFormatter.doesRelativeDateFormatting = true // Enabling relative date formatting

// other dataFormatter settings here, irrelevant for example
dateFormatter.timeStyle = .none
dateFormatter.dateStyle = .medium

let now = Date() 
let dateString: String = dateFormatter.string(from: now)  
print("dateString: \(dateString)") // Prints `dateString: <Today in current locale>`
