How do I avoid this while changing the character spacing of UITextView?

Question

I am trying to change the character spacing of uitextview. However it changes whole appearance. Screenshots:

Before adding the code

After adding the code

Code (as extension):

extension UITextView {

    func addCharacterSpacing(kernValue: Double = 1.15) {
        if let textValue = text, textValue.count > 0 {
            let attributedString = NSMutableAttributedString(string: textValue)
            attributedString.addAttribute(NSAttributedStringKey.kern, value: kernValue, range: NSRange(location: 0, length: attributedString.length - 1))
            attributedText = attributedString
        }
    }

}

If you are using NSMutableAttributedString, so you should customize it fully in the same way with paragraph style and fonts for it or any other settings.

From the screenshots I see a problem with paragraph style, setup it manually to the textView:

let paragraph = NSMutableParagraphStyle()
paragraph.alignment = .center

textView.attributedText = NSAttributedString(
     string: "string",
     attributes: [.paragraphStyle: paragraph])

Thank you but the font still is smaller than it should be. – Sep 03 '18 at 11:28
@AnnoThra what about: `let myAttribute = [ NSAttributedStringKey.font: UIFont(name: "Chalkduster", size: 18.0)!]` and add it too the `attributes`. Please check example: https://stackoverflow.com/a/32269975/1278744 – biloshkurskyi.ss Sep 03 '18 at 11:35
