Swift 4.2 Update

func addBoldText(fullString: String, boldPartOfString: String, baseFont: UIFont, boldFont: UIFont) -> NSAttributedString {

    //1
    let baseFontAttribute = [NSAttributedString.Key.font : baseFont]
    let boldFontAttribute = [NSAttributedString.Key.font : boldFont]

    //2
    let attributedString = NSMutableAttributedString(string: fullString, attributes: baseFontAttribute)

    //3. Note if 'boldPartOfString' is not a substring of 'fullString', enitre 'fullString' will be formatted with 'boldFont'
    attributedString.addAttributes(boldFontAttribute, range: NSRange(fullString.range(of: boldPartOfString) ?? fullString.startIndex..
