Reply to pas_panic_on_out_of_memory_error crash on tvOS 15.4 and 15.4.1
@DTS Engineer I think that I got general understanding of the issue that occurs. In our application we still depend on TVML Kit (which is marked as deprecated already). On many screens we use the stackTemplate with collectionList that contains big numer of shelfs (10-20) with lockups that allow to horizontally scroll the rows. Based on investigation of what is going on with memory I see that TVML engine does its best to speedup the process of rendering the lockup elements to provide the best experience while doing the quick scroll through the all shelfs. To handle it, the TVML uses some kind of rasterisation mechanism for TVML elements and display them as a single image in TVStackedImageView. It leads to issues in case of using the first generation of apple TV as rastered elements are kept in memory as long as the template keeps alive. There is a big difference in memory consumptions in case of using 4k display and 1080p. It seems to be related to fact that created images for 4K displays are

Reply to How to create file system snapshots with fs_snapshot_create?
I don't understand. Doesn't URLResourceKey.volumeSupportsFileCloningKey allow me to detect if cloning is supported? It does, and I think you'll find that it returns false when called on any SMB volume. I thought you were saying that with the deprecated Carbon API one can clone files, but then I don't understand why file clones are not preserved. Do you mean when copying a folder that contains file clones, those files are copied and not cloned? First of all, please try this with Finder paying attention to what you're doing and how it affects storage usage on the server. I've explained what's going on below, but it will make a lot more sense when you do the testing yourself. So, there are two different cases here: Copy from the local device to the remote server. Copying contents within a volume on the remote server. For case #1, the Carbon API and our other copy APIs have the same behavior and similar performance (if anything, Carbon will be slightly slower). As part of that, cloned files will be lost

Reply to FileManager.removeItem(atPath:) fails with "You don't have permission to access the file" error when trying to remove non-empty directory on NAS
It's more likely that Finder is calling a network-specific file operation for the SMB or AFP connection. You said you could work around the problem by manually doing a recursive delete. But does that mean that this actually works? Permissions can be complicated, especially on a Linux-based file server that the user could have configured in an unusual fashion.

Xcode 26 Beta-2 - missing context actions
If I control-click (or right-click) on a view, there is no longer an option to extract to subview. I also looked under the refactor option that comes up and it's not there either. Was this intentional? If so, is there an easy method to extract to a subview like in earlier versions of Xcode? Also, if I control click on a view and the context menu comes up, there used to be different embed options (ZStack, HStack, etc) now there's only embed. Not a big issue because you can just change Container to whatever.

Ios26 beta 3 concerns about liquid glass design
With the new ios 26 beta 3 helps some stabillty and performance issues but most of the liquid glass has been removed or made very frosty look; and it defeats the whole purpose of a big redesign, and even thought the changes are because of readability and contrast complaints it should not take away liquid glass design. I think apple should consider adding a toggle or choice to choose if they would want a more frosted look or a more liquid glass look the the original plan.

Can you remove Rosetta 2 on Apple Silicon?
I need to test my installer on Apple Silicon, and I have previously installed Rosetta so I no longer get the prompt to install Rosetta. The Mac mini and Macbook Air M1 that were ordered came with 11.0.1 and 11.0.0 respectively. The mini didn't have Rosetta and Air is pre-installed. Short of reinstalling Big Sur on the mini M1, how can I delete Rosetta 2?

Debug an issue with NSWindow becoming narrow
For months now we're trying to find an issue with one of our apps, were a window suddenly becomes narrow and can't be resized horizontally any more. It's a bug that only happens sporadically and we can't provide a focused test project to demonstrate the issue; thus we can't ask for code-level support at this moment. To debug this issue, we've overwritten a private method on NSWindow that gets the constrained window min and max sizes (valuable hint of Kristin from the AppKit team in a WWDC 2025 one-on-one session where I was able to show it to her in my debugger). When the bug hits, the maxSize's width (usually 10000) becomes smaller than the minSize's width. One way (but not the only one) to trigger this issue is to move the window from one display to another and back. Sometimes the bug triggers after a few back-and-forth movements, sometimes it takes minutes to trigger or I give up… but for other people the bug happens seemingly out of nowhere (of course there must be a trigger but we haven't noticed common

Reply to How to create file system snapshots with fs_snapshot_create?
You don't want to end up unnecessarily copying to the system volume when you could have cloned by staying inside the correct file system. I don't understand. Doesn't URLResourceKey.volumeSupportsFileCloningKey allow me to detect if cloning is supported? on the smb side, I don't think there's currently any way to preserve file clones across the smb copy, even when both sides support cloning I thought you were saying that with the deprecated Carbon API one can clone files, but then I don't understand why file clones are not preserved. Do you mean when copying a folder that contains file clones, those files are copied and not cloned?

Reply to Nomenclature Issue
It’s a conditional operator that takes three inputs, so calling it ternary conditional operator doesn’t seem like a big stretch. Regardless, I’m not the person you need to convince here. If you want to discuss this with Swift language folks, I recommend that you bounce over to Swift Evolution.
