CoreText note: Client requested name ".SFUI-Regular"

[nivbp7]

Describe the bug

I'm trying to set a strikethrough on text, to indicate that this item is complete.
I am using this code snippet to add the strikethrough
let struckText = NSAttributedString(string: todoText, attributes: [NSAttributedString.Key.nantesLabelStrikeOut: true])
When the label is rendered the following message appears in the console:
CoreText note: Client requested name ".SFUI-Regular", it will get TimesNewRomanPSMT rather than the intended font. All system UI font access should be through proper APIs such as CTFontCreateUIFontForLanguage() or +[UIFont systemFontOfSize:]. CoreText note: Set a breakpoint on CTFontLogSystemFontNameRequest to debug.

When setting the CTFontLogSystemFontNameRequest breakpoint, this is the first line in the stack trace.
method - drawStrike(frame: CTFrame, inRect: CGRect, context: CGContext)
file - Drawing.swift
let font = CTFontCreateWithName(myFont.fontName as CFString, myFont.pointSize, nil)

To Reproduce
Steps to reproduce the behavior:

let label: NantesLabel = .init(frame: CGRect(x: 20, y: 100, width: view.frame.width, height: 100)) let attributedText = NSMutableAttributedString(string: text, attributes: [NSAttributedString.Key.backgroundColor: UIColor.lightGray]) let struckText = NSAttributedString(string: text, attributes: [NSAttributedString.Key.nantesLabelStrikeOut: true]) attributedText.append(struckText) label.attributedText = attributedText view.addSubview(label)

Expected behavior
The font passed in with the attributes or the system font should be used
