Wrong text height when text contains emoji

This worked for me when text contains emojis. For NSAttributedString strings:

extension NSAttributedString {
    func sizeOfString(constrainedToWidth width: Double) -> CGSize {
        let framesetter = CTFramesetterCreateWithAttributedString(self)
        return CTFramesetterSuggestFrameSizeWithConstraints(framesetter, CFRange(location: 0, length: 0), nil, CGSize(width: width, height: .greatestFiniteMagnitude), nil)
    }
}

For String:

extension String {
    func sizeOfString(constrainedToWidth width: Double, font: UIFont) -> CGSize {
        let attributes = [NSAttributedString.Key.font : font]
        let attString = NSAttributedString(string: self, attributes: attributes)
        let framesetter = CTFramesetterCreateWithAttributedString(attString)
        return CTFramesetterSuggestFrameSizeWithConstraints(framesetter, CFRange(location: 0, length: 0), nil, CGSize(width: width, height: .greatestFiniteMagnitude), nil)
    }
}
