Reply to copyfile Sometimes Fails to copy .DS_Store when Copying a Folder But Does Not Report Usable Error
Mystery (partially) solved. I just took a sneak peak at the extended attributes of the .DS_Store file and some have a resource fork (probably the ones that were failing to copy I BET!). So appears to be the same failure we are talking about here: https://developer.apple.com/forums/thread/814076 .DS_Stores on the NAS's with resource forks.. maybe that will help you figure out leaky compression

Reply to filecopy fails with errno 34 "Result too large" when copying from NAS
Interesting and really good information to know! IF this is in fact a compressed file, then just copying the resource fork won't actually work. There's an additional UF_COMPRESSED file flag that needs to be set, which then marks the file as compressed so that the system knows to retrieve and decompress the file contents when the file itself is opened. If you read through the previous threads, you can see that this flag is what ends up hiding the presence of the resource fork from the rest of the system. However, if it was a compressed file then it should never have been written to the NAS device as a compressed file. All of our copy engines would have either automatically decompressed it (this is what happens if you copy the file without knowing about file compression) or noticed that the target DIDN'T support compression... and decompressed the file. Blame is definitely the critical factor here. The worst-case scenario

tvOS Simulator (also Xcode Canvas) Mapview Artifacts After Xcode Crash (26.3)
Have a peculiar problem I'm not able to solve. Working on an app with a mapview in the max zoomed out globe level. For some reason this morning Xcode froze/crashed when I was working and I had to force quit to get it back up. Then a new issue of graphical artifacts on the space section of the Mapview showed up. This Tuesday has now been spent in full on trying to solve this to no avail. I created a new project for iOS/iPadOS and added a similar map implementation. It works fine. I used Claude to help me after a few reinstalls of Xcode with this. I asked claude to summarize - this is what has been done: Claude generative AI summary starts here---------- Here's a complete summary of everything attempted: The Problem SwiftUI tvOS app with MapKit globe view showing severe rendering artifacts — corrupted pixels surrounding the globe. Started after Xcode crashed while the tvOS simulator was actively running. iOS simulator, macOS Maps app, and all native apps work perfectly. Only tvOS simulator MapKit is affected. H

Reply to File Export from iOS - eventually import too
Your code that wraps UIActivityViewController with UIViewControllerRepresentable and presents it in SwiftUI looks good to me. I've tried running the code on my iOS simulator (iOS 26.2 23C54) and here is the behavior I see: When sharing one single item, the code demonstrates the behavior as I described. When sharing two items (by using var shareItems: [Any] { [textItem1, textItem1] }), the Save as field isn't editable, and so there is indeed no way to specify the file names. Also, two files are generated, one for each item. So it's not that the way you present UIActivityViewController has anything wrong; it's that UIActivityViewController doesn't allow you to specify the file names when sharing multiple items. I don't see any way that can change the behavior because the UI of UIActivityViewController is system-provided. Please feel free to file a feedback report to request the feature you would like to have. For now, you might consider sharing one single item, if that is app

Reply to copyfile Sometimes Fails to copy .DS_Store when Copying a Folder But Does Not Report Usable Error
I think the idea you're getting at here is that you should be able to point your copy engine at any point in the file system, have it do the right thing based only on the information it's provided by copyfile, not external knowledge (like the full source path). [...] That's a lovely idea, but for better or worse, macOS just does not work that way. [...] but if you want to work with the full system... Well, I don't think there's any way to do without grappling with a whole bunch of edge cases. Well I did not directly point copyfile at .DS_Store and tell it to do the thing. I started a recursive copy on a folder, which happens to have a .DS_Store file in it. And on macOS just about every folder the user views in Finder will have one of those hidden in there, unfortunately. The folder I was copying was on a NAS, has like 24 videos in it. I'm doing this intentional slow copy to test everything out. So the copy gets like 98% done and then it needs a diaper change on the .DS_Store file! I

There was a small issue in the test project I submitted to FB22267894 [1], but when that is changed, if I set a breakpoint at createItem(named:type:inDirectory:attributes:) (for example) and then touch /Volumes/Sample/hi, I will reach the breakpoint in createItem and see the error that function outputted in Terminal. For example if I change createItem to return EIO, the touch command in Terminal then shows an input/output error. [1] Namely, my lookupItem sample implementation returned ENOSYS for any lookup other than the single static file implemented in the test file system. If it is changed to return ENOENT instead, then I can reach the createItem breakpoint.

Is it a bug in UIActivityViewController to Airdrop ?
Context: Xcode 26.3, iOS 18.7.6 on iPhone Xs In this iOS app, I call UIActivityViewController to let user Airdrop files from the app. When trying to send a URL whose file name contains some characters like accentuated (-, é, '), the transfer fails. Removing those characters makes it work without problem. The same app running on Mac (in iPad mode) works with both cases. I also noticed that even when airdrop fails, there is no error reported by activityVC.completionWithItemsHandler = { activity, success, items, error in } Are those known issues ?

Screenshots not uploading
I've been struggling for days to upload screenshots to App Store Connect. The Chrome console is showing multiple upload errors with status 0. One screenshot did sneak in and did upload, but every one I upload just fails without any messages. It will stick around with a gray box and cloud icon saying the file has not uploaded yet. I've seen multiple online posts from the past suggesting waiting (I waited 2 days), trying different browsers, private mode, resaving the image, etc.. I've never had this issue in years of uploading screenshots to App Store Connect. I really think this has to be an issue on App Store Connect but their status page doesn't show anything. Is anyone else having this issue?

Subscription unavailable
When my app tries to access a subscription, StoreKit's products(for:) always returns zero results. Similarly, SubscriptionStoreView always shows Subscription Unavailable followed by The subscription is unavailable in the current storefront. The app is a watch-only app (no iPhone companion app). The app and the subscription product were each approved in App Store Connect over two weeks ago. The problem occurs when the app is installed from TestFlight, when the app is installed from the App Store (production), and when run in the Xcode debugger. The only time the app successfully accesses the subscription when simulating it in Xcode with a .storekit file. How should my app access the subscription?
