Attributed string with custom fonts in storyboard does not load correctly

Question

We are using custom fonts in our project. It works well in Xcode 5. In Xcode 6, it works in plain text, attributed string in code. But those attributed strings set in storyboard

Answer 1

Thanks to this thread, I've come to this solution:

private let fontMapping = [
    "HelveticaNeue-Medium": "ITCAvantGardePro-Md",
    "HelveticaNeue": "ITCAvantGardePro-Bk",
    "HelveticaNeue-Bold": "ITCAvantGardePro-Demi",
]

func switchFontFamily(string: NSAttributedString) -> NSAttributedString {
    var result = NSMutableAttributedString(attributedString: string)
    string.enumerateAttribute(NSFontAttributeName, inRange: NSRange(location: 0, length: string.length), options: nil) { (font, range, _) in
        if let font = font as? UIFont {
            result.removeAttribute(NSFontAttributeName, range: range)
            result.addAttribute(NSFontAttributeName, value: UIFont(name: fontMapping[font.fontName]!, size: font.pointSize)!, range: range)
        }
    }
    return result
}
