On iOS 14 when attaching an image to a NSAttributedString the resulting height of the label is correct, however on iOS 15 it is too tall.

iOS 14:

iOS 15:

Code:

view.backgroundColor = .black


label.layer.borderColor = UIColor.red.cgColor

label.layer.borderWidth = 1


let font = UIFont.systemFont(ofSize: 11, weight: .bold)

let text = NSMutableAttributedString(string: "LIVE", attributes: [.foregroundColor: UIColor.systemGreen, .font: font])


let attach = NSTextAttachment()

attach.image = UIImage(named: "live_indicator_image")!

let imageString = NSMutableAttributedString(attachment: attach)

text.append(imageString)


label.attributedText = text

I fixed this by setting font attribute to the imageString.

imageString.addAttributes([.font: font], range: NSRange(location: 0, length: imageString.length))
