Adding strikethrough to NSAttributedString in iOS 11 with Swift

问题

Having some issues getting strikethrough to work. Currently I'm doing the following:

theString.addAttributes([
        NSAttributedStringKey.strikethroughStyle: NSUnderlineStyle.styleSingle.rawValue, 
        NSAttributedStringKey.strikethroughColor: UIColor.white
    ], range: NSMakeRange(0, 1))

It's not showing any sort of strikethrough though. Any ideas? I can't seem to find anything that works.

I use this to strike through a text in Xcode9/iOS11/Swift4 env

  let strokeEffect: [NSAttributedStringKey : Any] = [
        NSAttributedStringKey.strikethroughStyle: NSUnderlineStyle.styleSingle.rawValue,
        NSAttributedStringKey.strikethroughColor: UIColor.red,
    ]

   let strokeString = NSAttributedString(string: "text", attributes: strokeEffect)

swift 4.1

attributedText.addAttributes([
NSAttributedStringKey.strikethroughStyle:NSUnderlineStyle.styleSingle.rawValue, NSAttributedStringKey.strikethroughColor:UIColor.black],
range: NSMakeRange(0, attributedText.length))

    UIColor.black], range: textRange)

swift 4.2

    let mutPricesString : NSMutableAttributedString = NSMutableAttributedString()
    var attrPrice_1 : NSAttributedString = NSAttributedString()
    var attrPrice_2 : NSAttributedString = NSAttributedString()

    attrPrice_1 = NSAttributedString(string: "14000 KD", attributes:
            [NSAttributedString.Key.strikethroughStyle: NSUnderlineStyle.single.rawValue,
             NSAttributedString.Key.foregroundColor: UIColor.lightGray,
             NSAttributedString.Key.font: ARFont.Regular(fontSize: 15)])

    attrPrice_2 = NSAttributedString(string: " 12460 KD", attributes:
        [NSAttributedString.Key.foregroundColor: UIColor.black,
         NSAttributedString.Key.font: ARFont.Semibold(fontSize: 17)])

    mutPricesString.append(attrPrice_1)
    mutPricesString.append(attrPrice_2)

    lbl.attributedText = mutFollowersString
