Reply to Unable to upload an app with ExtensionFoundation
The Info.plist in my Extension is: Is that the actual value? Or did you substitute this line in: com.example.example-extension I've tried tracking your build down on the App Review side but there have been a number so submission and it looks like they've all been approved, so I'm not sure where to find the build that's being rejected. __ Kevin Elliott DTS Engineer, CoreOS/Hardware

iOS App Crashes after install but not when running from Xcode
I have an odd issue I'm trying to troubleshoot. I have an app that is deployed to our enterprise and works on almost all of our devices. Lately, I have devices (very small number) where the app installs from our MDM and it crashes upon launch, it does not get past the launch screen. If I remove and reinstall the app from the MDM it still crashes. I decided to put the devices in developer mode and if I run the App from Xcode on the device it works fine. If I stop it and run it right from the device it also works. If I do a final build of the app and install it using Devices and Simulators, the app crashes upon launch. Using Devices and Simulators I check for crash log for the app and no file. I am stumped as to whats going on.

Reply to Error in gathering code coverage in Xcode16
To be more clear than my post from August 2025, the solution is to rebuild all of your upstream dependencies with a version of XCode that includes the same version of clang that your version of XCode includes. The easiest way to be sure that upstream and your app uses the same clang is to build them both with the same XCode. If you rely on a library that you cannot rebuild, you need to file a bug with the maintainer for them to do that rebuild. Until those things have ALL been built with the same version of clang, you will not be able to see code coverage data.

Building macOS apps with Xcode 26 on macOS 26 VM
I'm trying to setup a macOS 26 build environment in a VM (using UTM and the virtualization framework Apple provides). I have Xcode 26 installed and have logged into my Apple ID and verified that the team and other configuration looks fine in Xcode settings. When trying to build the macOS app, I see errors saying the VM's device ID has not been registered. I have confirmed that the device ID is registered both in the Provisioning portal AND the downloaded .provisionprofiles (in Library > Developer > Xcode > UserData). This problem appears on multiple targets (e.g. the main app and extensions). If I try to manually provision the app, using the Provisioning portal, I can build the product, but it will not launch because of Gatekeeper issues. Finally, signing to run locally doesn't work either. As the app launches, frameworks refuse to load because Team IDs don't match. With ad hoc provisioning, there are no Team IDs. I've come to the conclusion that this just isn't possible. W

Reply to Matter Media Playback Cluster
Kevin and ssmith_c for your assistance. I fortunately managed to file in the bug: FB20677188 Thank you! Looking over the bug, there was one point I wanted to comment on: For the Matter Media Device Basic Video Player Type Apple Home does support the commissioning (adding the device to the list of accessories displayed in Home App), but no controls are displayed. Not even the mandatory required controls: ... This type of Matter Device, which is part of the standard, should at least expose the mandatory controls and commands. The idea that Apple (and general ecosystem vendors more broadly) should try and support the full range of the Matter specification is, IMHO, one of those ideas which sounds reasonable on the surface but is, in fact, a very bad idea. First off, quoting myself: The Matter specification itself is sufficiently broad and complex that, in practice, I'm not sure it will ever really be possible to create a high-quality controller app* that actually supports EVERY possible accessory configuration i

Reply to Request File Access from Unity for Apple Vision Pro
I am working on a Gaussian Splatting App using the UnityGaussianSplatting package and building for Apple Vision Pro. I want to be able to load splat (.ply / .splat) files from the Vision Pro's storage into the application. OK. So the main issue to be aware of here is the difference between works fine for a developer and works well for a user. For development purposes, you can basically just set the two keys (UIFileSharingEnabled/LSSupportsOpeningDocumentsInPlace) and then use your Documents directory as your working storage. There could be issues if you edited or deleted those files while your app was actively running, but you will just avoid those issues... by not doing that. On the other hand, if you're planning to ship this to end users then you'll need to use things like file coordination to avoid those issues. Similarly, apps that are more viewer oriented (meaning, they don't edit the files they're working with) often use an import model where they copy (actually clone, so they don't use additio

MetricKit Payload Not Populating on Enterprise
I'm working on adding MetricKit to our iPad application that we distribute internally via Enterprise distribution. I've set up the didReceive functions for both MXMetricPayload and MXDiagnosticPayload. When I build onto a device via Xcode and use the Simulate MetricKit Payloads command, everything works as expected. The issue I'm having is when testing on a device via our enterprise distribution. When I simulate a crash, I am receiving the MXDiagnosticPayload so that part is working correctly. However, I am never receiving a MXMetricPayload. I've been using the app and waiting up to 3 days in some tests and not receiving any payload over that time frame. Some information I found suggested the issue might be MetricKit not working fully on enterprise apps but I haven't been able to find a definitive source on that question. Hoping someone here can guide me on that. Thanks!

Clarification on APNs MDM Push Certificate per-customer requirement for MSP/multi-tenant MDM
Hello Apple Developer Community, We’re building an MDM product (SaaS, multi-tenant). I’d like clarification on the APNs MDM push certificate usage model for service providers (MSPs). Question: Is it acceptable for an MDM vendor to use a single APNs MDM push certificate owned by the vendor to manage devices for multiple, independent customer organizations? Or is it required/recommended that each customer (company) must obtain and use its own APNs MDM push certificate (issued under the customer’s Apple ID) for their tenant? Why we’re asking: We understand that many guides show the process where each customer logs into the Apple Push Certificates Portal with their own Apple ID, uploads a CSR provided by the MDM, and then renews yearly. Practically, for a small team and early-stage deployments, using one vendor-owned certificate across multiple tenants would be simpler. We want to ensure we’re not violating any policy, terms, or technical requirements (e.g., certificate ownership, topic binding, device t

Made a new launch story board and removed old LaunchImages
Converted my app to use a Storyboard instead of a Launch Image. Everything was working fine until I removed all of the Launch Images within Image.xcassets. I kept the icons. Then I started getting an error that: None of the input catalogs contained a matching image set named LaunchImage. The storyboard imageview referenced an image not inside of LaunchImage catalog (but perhaps it did now that its causing this problem). I rebuilt, clean build, checked plist for entry and got the same error. I figured there was something wrong with the Storyboard so I completely removed it, rebuilt a new one, new name new image file, assigned the png file to the imageview and I get the same error. I've tried everything. There must be some deep metadata assignment that is looking for this catalog, so I put it back in, with the files assigned to universal 1x, 2x and 3x. I used LaunchImage as the image file and it recognized it but still get the same error during build. I can even remove the storyboard and I get

Reply to Request File Access from Unity for Apple Vision Pro
Thanks @DTS Engineer for your quick & detailed answer!! So, my immediate question here is what your larger goal here actually is? I am working on a Gaussian Splatting App using the UnityGaussianSplatting package and building for Apple Vision Pro. I want to be able to load splat (.ply / .splat) files from the Vision Pro's storage into the application. This won't work. The primary goal of the App Sandbox is to protect user data, which is exactly the kind of data you want access to. Yeah, that was also what I suspected. Hence my question what the intended way to access files from an app would be. apps get access to files through one of two broad mechanisms: Thanks for referring to these, I think I stumbled upon it while researching, but did not consider them further yet because they are solutions that require editing the code in Xcode. Which poses two problems for me: 1 - I don't have a lot of experience with Swift and how Xcode apps are structured. 2 - The Xcode project is generated from Unity, s

How to get an anchored action sheet without the popover arrow on iOS 26?
I see in iPhone built-in apps that action sheets are presented as popovers without arrows over their originating views. Here is an example in Messages and Shortcuts apps. In WWDC 2025 session Build a UIKit app with the new design, the speaker explains that all you have to do is to configurate the popover like we do for iPad. Here is the relevant transcript: 14:33 ActionSheets on iPad are anchored to their source views. Starting in iOS 26, they behave the same on iPhone, appearing directly over the originating view. 14:46 On the alertController, make sure to set the sourceItem or the sourceView on popoverPresentationController, regardless of which device it’s displayed on. Assigning the source view automatically applies the new transitions to action sheets as well! Action sheets presented inline don’t have a cancel button because the cancel action is implicit by tapping anywhere else. If you don’t specify a source, the action sheet will be centered, and you will have a cancel button. iOS 26 provides a

Successfully uploaded iOS app builds don't appear in App Store Connect
Since 1st of September archives uploaded via Xcode 26 beta 7 or builds distributed via CD (fastlane deliver) don't appear in App Store Connect. No errors reported during/after upload process, no e-mails with errors received. Xcode reports successful upload (with a few warnings regarding dSYM) I'm not getting any e-mails with ITMS errors Builds don't appear at in App Store Connect in TestFlight section (not even in Processing or Failed states). For me it seems like App Store Connect outage but all statuses in https://www.apple.com/support/systemstatus/ are green.
