Are VisionOS Enterprise APIs handled differently from one another?
Hi, At work, we've done some development on an Apple Vision Pro. On the project, we used object tracking to track an object in 3D and found the default tracking refresh rate (I believe 5Hz)to be too slow so we applied for enterprise APIs so we could change it. At some point, in the capabilities (as a beginner to Swift and the Apple development environment) I noticed that's where you enable the Object Tracking Parameter Adjustment API and I did so, before hearing back about whether we got access to the enterprise API's and the license file that comes with it. So I setup the re-fresh rate to 30Hz and logged the settings of the ObjectTrackingProvider, showing it was set at 30Hz and felt like it was better than the default when we ran our app. In the Xcode runtime logs, there was no warning or error saying that the license file for the enterprise API was not found (and I don't think we heard back from Apple if they had granted our request or not - even if they did I think the license would be expired by now). Fast forward to today, I was running the sample code of the Main Camera access for VisionOS linked in the official developer documentation and when I ran the project in Xcode, I noticed in the logs that it wanted an enterprise license and that's why it wasn't running as expected in the immersive space. We've since applied for the Enterprise API for Main Camera Access. I'm now confused - did I mistakenly believe the object tracking refresh rate was set to 30Hz but it actually wasn't due to the lack of a license file/being granted access to the enterprise APIs? It seemed to be running as expected without a license file. Is Object tracking Parameter Adjustment API handled with different permissions than Main Camera Access API even though they are both enterprise APIs? This is all for internal development and not planning on distributing an app but I find the behaviour to be confusing between the different enterprise API? Does anyone have more insight as I find the developer notes on the enterprise APIs to be a bit sparse.

WatchOS Companion app on VPP Crashing on Launch
Hello, I sent this in as a feedback several weeks ago about watchOS 26.2 beta 2 but since the issue is still active now that watchOS 26.2 is in production I'm reposting here for the community. I would also like to submit a DTS about this issue but honestly don't know the best way to go about it and would appreciate advice about that. There seems to be an issue with VPP distribution for our app on watchOS 26.2. When our watchOS companion app is launched after being installed through VPP to a supervised iPhone, it encounters a dyld error before main() or any application code is even called. The same app launches correctly in every other circumstance we could imagine and test: – Installed through VPP on supervised devices running watchOS 26.1. – Installed from the app store (using an apple id) on a supervised iPhone and paired watch running iOS 26.2 / watchOS 26.2. – Installed through Testflight on a supervised iPhone and paired watch running iOS 26.2 / watchOS 26.2. – Installed through the app store on unsupervised devices running watchOS 26.1 and 26.2. This strongly appears to be a VPP signing issue because we even did the following experiment: Install iPhone and Watch apps through the App Store on a supervised device pair running public iOS 26.2 beta 2 / watchOS 26.2 beta 2. Verify that both apps launch successfully. Use an MDM command to install from VPP over the existing installations Verify that the watch app fails to launch (the iOS app is unaffected) My feedback included some crash logs which I won't be reposting publicly here. Any feedback or ideas appreciated.

Investigating Third-Party IDE Code-Signing Problems
I regularly see questions from folks who’ve run into code-signing problems with their third-party IDE. There’s a limit to how much I can help you with such problems. This post explains a simple test you can run to determine what side of that limit you’re on. If you have any questions or comments, please put them in a new thread here on DevForums. Put it in Code Signing > General topic area and apply whatever tags make sense for your specific situation. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Investigating Third-Party IDE Code-Signing Problems DTS doesn’t support third-party tools. If you’re using third-party tooling and encounter a code-signing problem, run this test to determine whether you should seek help from Apple or from your tool’s vendor. IMPORTANT Some third-party tools create Xcode projects that you then build and run in Xcode. While that approach is understandable, it’s not something that DTS supports. So, the steps below make sense even if you’re already using Xcode. To check that code-signing is working in general: Launch Xcode. In Xcode > Settings > Accounts, make sure you’re signed in with your developer account. Create a new project from the app project template for your target platform. For example, if you’re targeting iOS, use the iOS > App project template. When creating the project: Select the appropriate team in the Team popup. Choose a bundle ID that’s not the same as your main app’s bundle ID. Choose whatever language and interface you want. Your language and interface choices are irrelevant to code signing. Choose None for your testing system and storage model. This simplifies your project setup. In the Signing & Capabilities editor, make sure that: "Automatically manage signing” is checked. The Team popup and Bundle Identifier fields match the value you chose in the previous step. Select a simulator as the run destination. Choose Product > Build. This should always work because the simulator doesn’t use code signing [1]. However, doing this step is important because it confirms that your project is working general. Select your target device as the run destination. Choose Product > Build. Then Product > Run. If you continue to have problems, that’s something that Apple folks can help you with. If this works, there’s a second diagnostic test: Repeat steps 1 through 10 above, except this time, in step 4, choose a bundle ID that is the same as your main app’s bundle ID. If this works then your issue is not on the Apple side of the fence, and you should escalate it via the support channel for the third-party tools you’re using. On the other hand, if this fails, that’s something we can help you with. I recommend that you first try to fix the issue yourself. For links to relevant resources, see Code Signing Resources. You should also search the forums, because we’ve helped a lot of folks with a lot of code-signing issues over the years. If you’re unable to resolve the issue yourself, feel free to start a thread here in the forums. Put it in Code Signing > General topic area and apply whatever tags make sense for your specific situation.

After Waiting A Month For The Family Controls Entitlement, I'm Now Finding Out I Need One For Each New App ID To Be Signed?
Hey everyone, I was granted access to Family Controls (Distribution) for my main App ID The entitlement is visible and enabled in the App ID configuration. I’ve successfully created and used a provisioning profile that injects com.apple.developer.family-controls for the main app. ✅ However, the issue is with an extension target under the same parent App ID and all others Despite enabling the Family Controls (Development) capability in this extension’s App ID config, every new provisioning profile I generate for the extension fails to include the entitlement. I’ve confirmed this by: • Dumping the .mobileprovision with security cms -D → no sign of com.apple.developer.family-controls • Recreating the profile multiple times (Development and Distribution) • Ensuring the entitlement is toggled on in the portal • Validating the parent app profile does include it ⸻ ❗Question: Is there a known issue where Family Controls doesn’t get injected into extension App IDs even after team approval? Or is there an extra step I need to take to get this entitlement injected properly into provisioning profiles for app extensions?

Best Practices for Maintaining Long-Term Validity of Signed XCFrameworks
I am developing and distributing an XCFramework, and I want to ensure that it remains valid for as long as possible. I have some questions regarding certificate expiration and revocation: I understand that if an XCFramework is signed with a timestamp, it remains valid even after the signing certificate expires. However, if the signing certificate is revoked, the XCFramework immediately becomes unusable. As far as I know, Apple allows a maximum of two active distribution certificates at the same time. I assume that once a certificate expires, it will eventually need to be revoked in order to issue a third certificate. Is this correct? If an expired certificate is later revoked, will the XCFrameworks signed with that certificate also become invalid, even though they were timestamped? I want to ensure that released XCFrameworks remain valid for as long as possible. What is the best approach to achieve this? If anyone has insights or official documentation references on how to manage signing certificates for long-term XCFramework validity, I would appreciate your guidance. Thank you!

Side Button Access entitlement not appearing in Xcode capabilities list
Hi everyone, I'm trying to add the Side Button Access entitlement to my voice-based conversational app following the documentation, but I'm unable to find it in Xcode. Steps I followed: Selected my app target in Xcode project navigator Went to the Signing & Capabilities tab Clicked the + Capability button Searched for "Side Button Access" Problem: The "Side Button Access" option does not appear in the capabilities list at all. Environment: I'm developing and testing in Japan (where this feature should be available) Xcode version: Xcode 26.2 beta 3 iOS deployment target: iOS 26.2 Questions: Is there any pre-registration or special approval process required from Apple before this entitlement becomes available? Are there any additional requirements or prerequisites I need to meet? Is this feature already available, or is it still in a limited beta phase? Any guidance would be greatly appreciated. Thank you!

Outdated and Restrictive Certificate Signing Process
Title: Apple's Outdated and Restrictive Certificate Signing Process: A Barrier to Innovation Introduction In the dynamic field of mobile app development, the agility and freedom offered to developers can significantly dictate the pace of innovation and user satisfaction. Apple's certificate signing process, a legacy from an earlier era of computing, starkly contrasts with more modern approaches, particularly Android's Keystore system. This article delves into the cumbersome nature of Apple's approach, arguing that its outdated and proprietary methods hinder the development process and stifle innovation. The Burdensome Nature of Apple's Certificate Signing Proprietary Restrictions: Apple's certificate signing is not just a process; it's a gatekeeper. By forcing developers to go through its own system to obtain certificates, Apple maintains a tight grip on what gets published and updated. This closed ecosystem approach reflects a dated philosophy in an age where flexibility and openness are key drivers of technological advancement. Complex and Time-Consuming: The process to acquire and maintain a valid certificate for app signing is notoriously intricate and bureaucratic. Developers must navigate a maze of procedures including certificate requests, renewals, and provisioning profiles. Each step is a potential roadblock, delaying urgent updates and bug fixes, which can be crucial for user retention and satisfaction. Lack of Autonomy: Apple's centralized control means every application must be signed under the stringent watch of its guidelines. This lack of autonomy not only slows down the release cycle but also curbs developers' creative processes, as they must often compromise on innovative features to meet Apple's strict approval standards. Comparing Android’s Keystore System Developer-Friendly: In stark contrast, Android’s Keystore system empowers developers by allowing them to manage their cryptographic keys independently. This system supports a more intuitive setup where keys can be generated and stored within the Android environment, bypassing the need for any external approval. Speed and Flexibility: Android developers can use the same key across multiple applications and decide their expiration terms, which can be set to never expire. This flexibility facilitates a quicker development process, enabling developers to push updates and new features with minimal delay. The Impact on the Developer Ecosystem Innovation Stifling: Apple's outdated certificate signing process does not just affect the technical side of app development but also impacts the broader ecosystem. It places unnecessary hurdles in front of developers, particularly small developers who may lack the resources to frequently manage certificate renewals and navigate Apple’s rigorous approval process. Market Response: The market has shown a preference for platforms that offer more freedom and less bureaucratic interference. Android's growing market share in many regions can be partially attributed to its more developer-friendly environment, which directly contrasts with Apple's tightly controlled ecosystem. Conclusion Apple’s certificate signing method, while ensuring a secure environment, is an archaic relic in today’s fast-paced tech world. It binds developers with outdated, proprietary chains that hinder rapid development and innovation. As the technological landscape evolves towards more open and flexible systems, Apple’s restrictive practices could potentially alienate developers and erode its competitive edge. For Apple to maintain its relevance and appeal among the developer community, a significant overhaul of its certificate signing process is not just beneficial—it's necessary.

xcode unable to find app store provisioning profile in command line build
Hi, I am trying to make my app build on GitHub Action CI pipeline. App builds fine on xcode on my mac. For CI I am using command line xcode. I am getting following error: No profiles for 'com.snslocation.electricians-now' were found: Xcode couldn't find any iOS App Development provisioning profiles matching 'com.snslocation.electricians-now'. Automatic signing is disabled and unable to generate a profile. To enable automatic signing, pass -allowProvisioningUpdates to xcodebuild. (in target 'myapp' from project 'myapp') You can see full log of the build here: https://github.com/nbulatovi/ElectriciansNow/actions/runs/12603115423/job/35127512689 The provisioning profile is present, and verified in the previous steps in the pipeline, however xcode refuses to find it. If I add -allowProvisioningUpdates error stays. I tried manually mapping app id to profile name. Is there a way to get any debug log from xcode profile search, to see why is it not picking up the correct profile? Or can you maybe help in some other way? xcode version is 15.4, iOS SDK 17.5
