Hi all, I have set up a trivial test project to try Apple-hosted background assets following the instructions in the three articles at https://developer.apple.com/documentation/backgroundassets.
When I run the local mock server with xcrun ba-serve and set the URL override in Settings as described in the "Testing asset packs locally" article, I am able to download a test pack on my iOS devices. On the Mac that I use to run the mock server, however, the same call to AssetPackManager.shared.assetPack(withID: "TestAssetPack") that works on iOS always reports
The asset pack with the ID “TestAssetPack” couldn’t be looked up: No asset pack with the ID “TestAssetPack” was found.
even when not running the mock server, which led me to believe that it may not be hitting it at all. In fact, the macOS app will download asset packs uploaded to App Store Connect even when running the local server and setting the xcrun ba-serve url-override to the exact same string as in Settings on iOS. My initial suspicion was that something is wrong with the URL override, so I have tried all combinations of the Mac's hostname, IP address or "localhost" (with the corresponding SSL certificates) with and without port 443, always prefixing with "https://" for the url-override. All the same.
Does anyone have an idea what may be the issue here?
My asset pack has the following manifest:
{
"assetPackID": "TestAssetPack",
"downloadPolicy": {
"onDemand": {}
},
"fileSelectors": [
{
"file": "TestAsset.txt"
}
],
"platforms": [
"iOS",
"macOS"
]
}
I am running v26.1 for macOS, iOS & Xcode.
Edit:
Just to be clear, my assumption here is that the URL overrides (in Settings on iOS or via ba-serve on macOS) is what should cause the app to hit the mock server. Is that correct or am I missing something?

I'm adding a few custom signposts with mxSignpost(.begin,...) and mxSignpost(.end,...). Is there a way to force delivery of the MXMetricPayload so I don't need to wait for the daily aggregation to be pushed?
Windows 10 使用 VirtualBox 创建的 Monterey 12.6.7 macOS 虚拟机不能识别到 iPhone 7 手机。
iPhone 7 已经连接到电脑主机 (win 10) 的 USB 3.0 口子,手机已经信任电脑。
在 win 10,我看到了 “此电脑\Apple iPhone”,就是说,宿主机识别到了 手机。
现在,开启macOS 虚拟机,虚拟机右下角的 usb 图标,显示并且勾选到了 "Apple Inc. iPhone [0901]",但虚拟机还是没看到手机设备,导致 Xcode 也看不到手机设备。
虚拟机运行后,插拔 iPhone 7 手机,通过

Hello, I have a question about running tests on multiple simulators.
Currently, my company has a WDIO+Appium test suite with XCUITEST driver that runs on a single simulator through a mockttp proxy (we are intercepting and mocking some of the responses from our APIs and pass through the rest). In order to route the traffic we are currently using 'networksetup -setsecurewebproxy '. Everything works as expected.
With growing number of tests we'd like to scale number of simulators on a single host to 3-5. We have a working setup but the problem are system-wide proxy settings routing traffic from multiple simulators, which we can't distinguish by UDID or any other means, we know of. We can spin multiple mock servers on the same machine but we are struggling to find the way to route the traffic on a simulator basis.
In the end, both options are viable:
1 mock server running for multiple simulators
N number of mock servers for N number of simulators
Has anyone had the same/similar problem? How to approach this? We are currently running on Sequoia OSX and platform version 18.6. Thanks!
Hi everyone,
I’m hoping someone here can shed some light on what’s going on with Apple’s one-hour security delay when trying to register an iPhone for development use.
I’m currently setting up an app build using Expo / EAS and a paid Apple Developer account. Every time I scan the device registration QR code or try to authorise my iPhone as a development device, I get hit with a “security delay — try again in one hour” message.
This happens every single time, even if I wait the full hour. The device is the same iPhone I always use, signed in to the same Apple ID, and verified with 2FA.
The only thing unusual about my setup is that I’m using Starlink for internet access. Because Starlink uses dynamic IP routing and your exit node changes frequently (depending on which satellite or ground station you’re on), it looks like I’m signing in from a new location each time — sometimes even hundreds of miles apart.
It seems that Apple’s security system flags each of these as a “new login” or “new device registration,” then enforces a one-hour safety lockout. That makes it basically impossible to register my device and proceed with iOS builds or testing.
Has anyone else run into this problem while using Starlink (or other dynamic-routing connections like VPNs or cellular hotspots)?
And if so — is there any known workaround or setting to whitelist a device, stabilise verification, or bypass the repeated one-hour wait?
This feels like an over-protective security feature that doesn’t play well with modern satellite internet setups.
Any insights from the Apple engineers or other developers would be hugely appreciated.
Thanks,
Tim Lazenby

After combing the forums and release nodes, here are some extra notes to help other developers using Apple-Hosted Background Assets. I don't promise I got this perfect, but it may help direct you.
AssetPack.Status is an OptionSet (not an enum!) - Critical API detail missing from guide
It's a bitmask where values can be combined
2⁰ (1) = available to download
2¹ (2) = update available
2² (4) = up to date
2⁶ (64) = downloaded
Example: status value 69 = 0b1000101 = available + up to date + downloaded
Use .contains() method to check specific flags
AssetPack.version property - Undocumented feature
Auto-assigned by App Store Connect for Apple-hosted packs
Increments with each upload of same asset pack ID
No file deduplication across asset packs
Same file in two packs = counts twice toward 200GB limit
Best practice: create separate pack for shared files
Shared namespace path requirements
Asset pack ID is NOT part of file path
Each file must have unique relative path across ALL app's asset packs
Example: Foo/10/239/414.png and Bar/10/239/414.png are distinct and won't collide
Additional url(for:) bugs beyond iOS 26.1 fix
iOS 26 Beta 5: "item with same name already exists" error
Workaround: Request URL for directory, then manually append filename
TestFlight-only availability - Major limitation not mentioned!
Apple-hosted packs currently ONLY work for internal testers on TestFlight or from App Store.
Won't work from Xcode until "later this year"
HTTP 400 errors expected for non-TestFlight installs
ba-serve port workaround
URL override port bug exists on multiple device types
Use ba-serve -p 443 instead of custom ports
Hello,
I'm building this mobile app using Quasar - Capacitor on iOS.
The app is working perfectly, but I'm encountering an issue whenever I push the rep I get this error: "Error
Unable to open base configuration reference file '/Volumes/workspace/repository/ios/App/Pods/Target Support Files/Pods-App/Pods-App.release.xcconfig'.
App.xcodeproj:1"
I've tried every possible solution and made sure that everything is set perfectly.
Can anyone please help me with that?
Thanks in advance, appreciate you 🫶🏻
My App is not compatible with iPhone 15 but can run on iPhone 14 perfectly fine, what could be the problem?

Hi everyone, I've been trying to integrate with Microsoft EntraID for more than a week. I've followed every tutorial, ChatGPT, Cloude.ai, etc, but nothing works, and I realized that the problem is setting up information inside the Info.plist correctly. In the old days, we were able to edit it, but now it's a mess. I'm working with Xcode 15.2. Unfortunately, my computer does not accept more upgrades. Yes, I know I have to buy a new one, but I'm not sure if the new version will help me solve that. Does anyone have a project example or some experience with Microsoft EntraID authentication using SwiftUI?
All the examples in the project are really old and usually don't use SwiftUI

I am working on an iOS app and I want to achieve on demand module download inside the app when the user clicks on the module icon which he wants to use.
The idea is that we have a super app consisting of multiple modules say four independent apps/features and I want to separate each one so that when the user selects a specific app/feature, it’s downloaded on demand and then opened directly within the same super app resulting in a lower app size initially
I want to upload all the code of all modules to app store connect but when the user downloads the app, then only one module's code should be available to the user, the rest of the module's code should be downloaded when the user wants to use that module. I know apple restricts downloading new code but in my case I want to upload all the code to app store for review but just give option to the user to get rest of the code when needed. Any guidance, architectural advice, or example implementations would be highly appreciated.

I would like to know if macOS DEXT supports the following networking features: Tx/Rx Multiqueue, RSS, RSC, NS/ARP offload, PTP or packet timestamping and TSN.
I couldn't find relevant documentation for these features in the Apple Developer Documentation.
If they are supported, could you let me know which features are supported and how to find the corresponding official Apple documentation?
Thanks

In the online documentation for InstallerJS, it is stated that the unit for the availableKilobytes property of the target field is kilobytes.
Isn't it actually bytes because of a bug in the very first release of macOS that supported InstallerJS?
[Q] Has there been a fix in the recent years regarding this property that would explain why the documentation says it's kilobytes? Even though at the time of this writing, the unit is still bytes when you call my.target.availableKilobytes
I'm using this call to dump the value of this property in install.log:
system.log(my.target.availableKilobytes + '');
Ref. https://developer.apple.com/documentation/installer_js/target/1811975-availablekilobytes

I have a project inside the project structure. I have around 300 unit tests in the project.
I see that for some of the subprojects, the coverage numbers show up correctly, but for other subprojects and the main project, the coverage number shows zero, even though the tests are running successfully.
The log I get is:
Aggregation tool emitted warnings:
warning: /Users/ABC/Library/Developer/Xcode/DerivedData/projectABC-hfzmkbdgpiswoxfvvnvhrafaiqyb/Build/ProfileData/A8EEC1FB-1699-4C29-A88C-D3DDA226DBC0/0A416494-A393-4319-AA47-502D72084C9C-43351.profraw: raw profile version mismatch: Profile uses raw profile format version = 8; expected version = 10
PLEASE update this tool to the version in the raw profile, or regenerate the raw profile with the expected version.
I only have one Xcode (26.0.1) on my machine. I tried cleaning the derived data, the cleaning project, and rerunning the tests, but it hasn't helped.
Please help me get the coverage number back. Thank you.
We are experiencing an issue where our app gets stuck during launch. The splash screen appears for some time, and then the app either becomes unresponsive or closes unexpectedly. However, there are no crash logs captured in Xcode or Firebase Crashlytics, indicating that the app is not crashing but rather being terminated. This issue is preventing affected users from properly launching the app.
Additionally, some users have reported occasional lag and slow performance when using the app. The issue occurs only for a specific subset of users and appears to be related to other Electronic Logging Device (ELD) apps running in the background. When these apps are active, our app struggles to launch and sometimes becomes unresponsive.
We suspect that this behavior could be related to system resource allocation, such as high memory consumption by background apps, which might be affecting our app's ability to launch correctly. However, we have been unable to reproduce the issue on our end despite multiple attempts.
Actions Performed During App Launch:
Firebase configuration
API requests, including:
Fetching account details
Registering the FCM token with the server
Asynchronous background requests to fetch POI details
Creating a local database and storing POI data in local storage
We would like guidance from Apple regarding potential causes and debugging strategies, especially in scenarios where the app does not produce crash logs but still fails to launch properly. Any insights into memory management, conflicts with background applications, or system resource constraints would be highly appreciated.
Steps to Reproduce:
Install and launch the app on an affected device.
Observe that the app gets stuck on the launch screen.
After some time, the app terminates unexpectedly.
Issue is inconsistent and occurs only for certain users.
Presence of other ELD apps running in the background appears to influence the issue.
I received this message when trying to submit a build using Rork.com. Can anyone tell me what this is and how to fix it?
There is a problem with the request entity - You are not allowed to create 'iOS' profile with App ID 'XXXXXXXX'.
✖ Failed to create Apple provisioning profile
Error: build command failed.

Title basically explains what my issue is, from what I understand the only way to set an icon in an tauri app is using a icns file, I could be wrong but I don't know how to get macos theme changing stuff to work with it because of the icns file.
I developed an app using Unity and exported it as an iOS project file so that I could package it in Xcode. Now, I’m facing an issue where users who previously installed version 1.0 are still seeing the old version after installing the updated version 2.0. Although the installation process for version 2.0 appears to complete (with the installation animation), the app still opens as version 1.0. I am an individual developer but used enterprise signing for distribution. I’m quite confused and have looked into the issue—some sources mention it might be related to CFBundleVersion, but modifying it didn’t help. I’d really appreciate some help with this. o(╥﹏╥)o

Hello,
I'm developing a macOS application that uses the Virtualization framework to run Linux virtual machines (specifically Ubuntu and Fedora) on Apple Silicon Macs.
I've noticed that while the macOS host properly supports all trackpad gestures, the two-finger tap gesture for right-click does not work within the Linux guest. Only the primary click is recognized. This behavior is consistent across different Linux distributions and desktop environments (GNOME, KDE, etc.).
I would like to confirm:
Is the macOS Virtualization framework expected to support trackpad gestures such as two-finger tap for right-click within Linux guest VMs?
If not currently supported, is there a known workaround to enable right-click functionality for the trackpad in Linux guests? (e.g., configuration changes in the VM, Linux kernel input modules, or framework-level adjustments.)
Any insights or suggestions would be greatly appreciated.
Thank you!
