Basic HTML strings do not display correctly on macOS Sonoma, I am wondering if there is an alternative technique that can be utilized. There was a minor change in macOS 14.2, which fixed some cases but made others much worse.
Consider the following code:
override func viewDidLoad() {
super.viewDidLoad()
let html = """
<table width="100%" border="1" style="color: white">
<tr>
<td align="left">Left</td>
<td align="right">Right</td>
</tr>
</table>
"""
let data = Data(html.utf8)
let definition = try! NSAttributedString(data: data, options: [.documentType: NSAttributedString.DocumentType.html, .characterEncoding: NSNumber(value: String.Encoding.utf8.rawValue)], documentAttributes: nil)
let frameRect = NSRect(x: 100, y: 0, width: 300, height: 200)
let textView = NSTextView(frame: frameRect)
textView.textStorage?.setAttributedString(definition)
textView.backgroundColor = .clear
view.addSubview(textView)
}
On macOS 14 (23A5312d) it looks like this (FB13170237):
On macOS 14.2 (23C64) it looks like this (FB13465833):
