There is a macFUSE bug that can result in an Input/output error - https://github.com/osxfuse/osxfuse/issues/45 when listing a directory. In most cases this doesn't cause any major issues, just a "ls: mount: Input/output error" message when running ls.
The problem is that the contentsOfDirectory(at:includingPropertiesForKeys:options:) now does not work, however, the contentsOfDirectory(atPath:) method does.
There appears to be a difference in how these methods handle errors, although the documentation doesn't seem to suggest this.
The following code returns an array of strings without an error:
FileManager.default.contentsOfDirectory(atPath: "/Users/user")
The following code results in an error:
FileManager.default.contentsOfDirectory(at: URL.init(fileURLWithPath:"/Users/user"), includingPropertiesForKeys: nil)
REPL:
$E3: NSError = domain: "NSCocoaErrorDomain" - code: 256 {
_userInfo = 3 key/value pairs {
[0] = {
key = "NSURL"
value = "file:///Users/user/mount"
}
[1] = {
key = "NSFilePath"
value = "/Users/user/mount"
}
[2] = {
key = "NSUnderlyingError"
value =
}
}
}
Xcode:
Error Domain=NSCocoaErrorDomain Code=256 "The file “mount” couldn’t be opened." UserInfo={NSURL=file:///Users/user/mount, NSFilePath=/Users/user/mount, NSUnderlyingError=0x600000289740 {Error Domain=NSPOSIXErrorDomain Code=5 "Input/output error”}}
Passing [] as the includingPropertiesForKeys value gives the same result.
It's also interesting that in the REPL the NSUnderlyingError value is missing.

Recently simulators have not been able to be downloaded from Xcode, after endlessly trying the transfer rate was well below 100kb/s and would fail after a short while. The speed was on average 100x slower than other servers with the exception of a short spike of passable speeds.
Because Xcode for some reason doesn't support resuming simulator downloads, I downloaded the simulators directly from the dvtdownloadableindex file using two different methods but the fileSize values consistently differed slightly from the downloaded files.
This resulted in a Missing Signature error when adding the simulator with xcrun simctl runtime add.
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):
