The NSFormatter for Converting English Number to persian or arabic Number in Swift 3

Question

I read the similar questions here and Write this method in my app

        let formatter = NumberFormatter()

    func convertEngNumToPersianNum(num: String)->String{
        let number = NSNumber(value: Int(num)!)
        let format = NumberFormatter()
        format.locale = Locale(identifier: "fa_IR")
        let faNumber = format.string(from: number)

        return faNumber!


    }

I didn't get Error But I didn't get the result too!

my Number code is this :

let checkNumber = Home2ViewController().customtitle.count
    personalCustom.text = ("\(checkNumber)")

I used another Number in another View Controller that works But I want to show this Number in persian or arabic number format not in English format

Try this :

func convertEngNumToPersianNum(num: String)->String{
        //let number = NSNumber(value: Int(num)!)
        let format = NumberFormatter()
        format.locale = Locale(identifier: "fa_IR") 
        let number =   format.number(from: num)
        let faNumber = format.string(from: number!)
        return faNumber!

    }

OR repalce with your line

        let number =   format.number(from: num)
    let faNumber = format.string(from: number!)
