hi Question is in the title.. do we already know the length of the vectors? best regards

I am building and running a simple Open MPI C application. In order to run it, I configured the run process in this way:\ Edit Scheme -> Run -> Info -> Executable -> Other... -> /path/to/mpiexec Edit Scheme -> Run -> Arguments -> Arguments Passed On Launch -> -np 4 "$(BUILT_PRODUCTS_DIR)/$(EXECUTABLE_NAME)" Now, instead of the hardcoded "4" as the number of processes, I want to specify an environment variable (like the already existing BUILT_PRODUCTS_DIR and EXECUTABLE_NAME environment variables), so I enter in Environment Variables NUM_PROCS as Name and 4 as Value. Thus, I write in Arguments Passed On Launch the whole quoted string: "-np" "$(NUM_PROCS)" "$(BUILT_PRODUCTS_DIR)/$(EXECUTABLE_NAME)". And Xcode can't read the NUM_PROCS environment variable (despite I can easily read it in the C program by a getenv("NUM_PROCS")!), in fact, it runs the default number of processes of my system (12). I tried in a very large number the different ways of writing arguments (every string on a new line, with quotes, without quotes, ...), but none worked as I expected.

I have an iOS/iPadOS app. When I run the app on Mac as a Designed for iPad app, Save button on the Share Sheet crashes the app. I want to share a view with ImageRenderer, but here's an even easier example where I am trying to share an SF Symbol as an image. ShareLink(item: Image(systemName: "swift"), preview: SharePreview(Text("PNG"), image: Image(systemName: "swift"))) Share button works. It opens Share Sheet. "Add to Photos" works. "Copy" works. I can paste the image file in Finder after I press "Copy". But when I press the "Save" button, my app crashes with the error: Thread 1: "-[NSItemProvider pathExtension]: unrecognized selector sent to instance 0x600001c1e290" How to fix this error? How to make saving the image work? Maybe I need additional permissions in plist? I already have "Privacy - Photo Library Additions Usage Description" and everything on iOS and iPadOS works without a problem.

Hi community! It is known that application designed for iOS may be launched on MacOS with arm chip. With XCode this is simple, you just choose to launch on current machine (Designed for iPad). As I can see, some magic happens: some tool wraps myproj.app into another app, which contains WrappedBundle link and Wrapper subdirectory. Does anybody know how to invoke this wrapping tool via command line? I am using CLion as IDE for my personal preferences, and I want to build app with CLion and wrap the result with external tool into a MacOS-compatible app to test if it works for MacOS as well. In other words, having the myproj.app I want to run something like "magictool -wrap /path/to/myproj.app" Best regards!

Since I haven't heard so much as a peep from Apple on this, I thought I'd take a poll here on how long I could expect an easily reproducible (albeit possibly obscure) kernel panic to be fixed. I was under the impression that kernel panics were a big deal but it's been almost 2 months since I updated from macOS 14 to macOS 15.0 dev beta 7 / public beta 5 when I originally came across and reported a panic triggered while playing StarCraft II. I've been able to consistently trigger panics playing certain (maybe all) Co-op maps in SC2 and since my first report Aug 22, I've filed 8 additional bug reports, each automatically generated after hitting yet another panic. (I'm not sure exactly who is able to view these but for what it's worth, these are the reports I've filed so far: FB14886510, FB14905773, FB14960435, FB15304609, FB15391195, FB15467943, FB15468127, FB15491485, FB15491684.) A few other people have reported the issue to SC2's developer, Blizzard, and apparently Blizzard has acknowledged they're aware of the problem so it's safe to rule out the possibility of a hardware defect or other issue specific only to my computer. The logs point the blame at the AppleDCP driver, although I suppose the problem could technically be in the DCP firmware instead. Regardless, Apple's code is clearly at fault here. I'll admit the importance of a video game isn't exactly like keeping the power on at a hospital but I don't know why it would be deemed particularly unimportant either. At 53 days in, am I wrong to expect this to have been fixed by now or is Apple really being that slow?

I developed my app with React-Native-CLI, version 0.67.2. I use Xcode 16 on MacOS Sequoia 15.0.1 It builds and runs fine on any simulator, iOS 17 or iOS 18. As soon as I build it for my iPhone 12 iOS 17.6.1 or archive, it throws this error "Command PhaseScriptExecution failed with a nonzero exit code" at the last time. It actually starts the Metro. I made my iPhone into developer mode. Paired it with MacOS. The thing I don't get why it doesn't work on my iPhone when it works fine on simulators. It doesn't even archive. Anyone encountered something like this in the past?

I have an Intel based Macbook Pro, which I use for iOS development. Recently I have the need to test my apps on M-series Apple Silicon based simulator images (specifically, 13 inch versions of iPads) which have no "A" series equivalent (iPad Air 13, iPad Pro 13, etc). I have "created" simulators for these devices in Xcode Simulators and Devices, but they do never appear under the File > Open Simulator menu. I have confirmed that creating a new simulator with any A-class device does not exhibit this issue. Interestingly, these device types do NOT appear under the same "Device Type" menu when attempting to create a "New Simulator" from within the Simulator itself. Creating a Simulator in "Device and Simulators" The same menu from inside the "Simulator" app - missing M-class devices: Can anyone confirm, preferably with a link to the documentation, that this is intended behavior? Apple expects us to support M class devices, on still-supported Intel devices, without access to appropriate simulators? Or is this just my machine? System: 16-inch, 2019 MacBook Pro Sonoma 14.0 Xcode 15.4 (15F31d) Thank you

It seems that Xcode Cloud currently only uses Intel machines for running the workflow jobs. When will Apple Silicon machines be available and supported?

I want to get MacOS Version from Objective-C build for iOS Apps to run on Apple Silicon Mac. Because AppStore In-App Purchase on Apple Silicon Mac had issues on MacOS version 13.0 and was fixed at version 13.3.1. I need to know the exact version of the MacOS to prevent users from buying In-App Purchases. I found that I can get iOS version that the app is emulating on and assume MacOS version from iOS version. But I think it's not 100% guaranteed way, because no documentation says anything about it. Is there a way to get MacOS Version in iOS Apps running on Apple Silicon Mac?

Hello, I have an iPad app that users are running on their M1 / M2 MacBooks thanks to the "Designed for iPad" feature. Some of them reported to me that the pressed keyboard keys were not recognized. According to my source code, it seems that my custom views (that are set as firstResponder) do not get pressesBegan events. While I could not reproduce this specific problem on my M1 Macbook, I found a strange problem that may be related. My view also supports interaction with game controllers. I found that the emulated controller (which is using the keyboard, when the controller emulation feature of the Designed for iPad app is set to On) has some problems. The valueChangedHandler of the GCExtendedGamepad from the GCGameController is only fired if the app is compiled with the "Requires full screen" option set to On. If Requires full screen is unchecked in XCode, the Emulated Controller is still present in the list of game controllers, but no button callbacks are triggered. Note that a real game controller connected via USB will work correctly no matter how Requires full screen is set. Could there be a focus bug of the keyboard not sending events when the app is not a full screen app (resizable on mac, and multitask on iPad)? Or is there something I can change to avoid this problem? I'm lost.

Our apps can currently be installed on Apple Silicon Macs via the iPad app on Mac feature (“Designed for iPad”). Now we are working on “proper” (universal) Catalyst-based Mac apps that will be available on the Mac App Store. How does the transition work for users that currently have the iPad version installed? Will they automatically update to the Mac Catalyst app once it’s available, or do they need to re-install the app from the Mac App Store?

Hello all, I am wondering if anyone can help me with writing a script that fully uninstalls an app with one click or can point me to a script already written please? So that when I click the script it uninstalls the app and leaves nothing behind. So when I click finder and use the search function with the name of the app, then click add and then name matches (input name of app) then click add and select system files are included, nothing comes up as the script has completely removed it from my system. I am Using Mac Mini M2 Pro 16gb ram and macOS Sonoma. Thank you

Hi, Reading the copyFromBuffer documentation states that on macOS, sourceOffset, destinationOffset, and size "needs to be a multiple of 4, but can be any value in iOS and tvOS". However, I have noticed that, at least on my M2 Max, this limitation does not seem to exist as there are no warnings and the copy works correctly regardless of the offset value. I'm curious to know if this is something that should still be avoided. Is the multiple of 4 limitation reserved for non Apple Silicon devices and that note can be ignored for Apple Silicon? I ask because I am a contributor to Metal.jl, and recently noticed that our tests pass even when copying using copyWithBuffer with offsets and sizes that are not multiples of 4. If that coul cause issues/correctness problems, we would need to fix that. Thank you. Christian

I use to testing iOS app directly on my M1 Mac mini, without needing to plug in an iPhone. After updated to XCode 15.4, this option is gone.

Hi All, Finder is caching the old application name and not showing the new application. I am deploying my iPad app to M1 Mac by generating a package file. In the newer version of this application, I have changed my application name and deployed the application from backend to user machines. Eventhough application is deployed successfully, the application name still remains the old. I went through the forum and tried the reset the finder cache and launcher service caches, but still the new application name is not coming. But when I uninstall and reinstall the application it is showing the new application name. Can someone suggest a way to reset this using script, as we are deploying the application from backend, we dont have direct access to the client machines Thanks Ranga

When rendering gradient of luma values you can clearly see that the monitor output from Apple Silicon GPU has lifted/curved blacks (values 0-31 out of 1024 in 10-bit output). Any idea what is going on and how to remediate? It looks like some kind of compensation/calibration for the screen panel response, but it is baked into output regardless of what kind of monitor (or non-monitor) is connected. The same rendering on Intel architecture produces correct linear gradation. We have tried M1, M2, M3 and they all seem to be affected.

I am using XCode on my Mac Book Pro M1 and trying to run the iOS app being developed on my iPad (5th generation, 12.9 inch) The devices are connected through USB-C cable. I have enabled developer mode on my iPad, trusted the M1 device, the developer, and the app. However the following appears on the iPad when trying to launch the app: Unable to Verify App An internet connection is required to verify trust of developer "Apple Development: ...". This app will not be available until verified This seems to be an issue with M1 specifically, as other people seem to have this problem, and the application successfully runs on other iOS devices
