Adding font size and custom font name to attributed string in UITextView

Question

I have the following code to add the attributed string to the UITextView text. I need to add the custom font and font size to it in swift. How to do it?

    func setAttributedString(string: String) -> NSAttributedString {
    let attrString = NSMutableAttributedString(string: string)
    let paragraphStyle = NSMutableParagraphStyle()
    paragraphStyle.lineSpacing = 7
    paragraphStyle.minimumLineHeight = 7
    attrString.addAttribute(NSParagraphStyleAttributeName, value:paragraphStyle, range:NSRange(location: 0, length:attrString.length))
    attrString.addAttribute(NSFontAttributeName, value: UIFont.systemFont(ofSize: 30), range: NSRange(location: 0, length:attrString.length))
    return attrString
  }

I need to add the custom font and font size to the following function. How to achieve this?

You will hopefully get your answer from link. Just convert syntax to latest swift syntax. — Tushar Sharma

Use the initializer init(string:attributes:)

https://developer.apple.com/documentation/foundation/nsattributedstring/1408136-init

let attrString = NSMutableAttributedString(string: string, attributes:
            [NSFontAttributeName:UIFont(
            name: "Georgia",
            size: 18.0)!])
    //Add more attributes here

In Swift 3

let attributes = [NSAttributedStringKey.font: UIFont(name: "HelveticaNeue-Bold", size: 17)!, 
              NSAttributedStringKey.foregroundColor: UIColor.white]

let attributedString  = NSMutableAttributedString(string: "Your string" , attributes: attributes)
