I'm developing for compliance with Texas law in the United States.
Currently, I'm encountering an issue where I want to test the feature point "when the app undergoes significant changes, a supervised user initiates a request." However, during actual testing, the app pops up an error message: "Can't Ask, An Unknown error occurred."
Additionally, I see the following error message in the Xcode Console: "Error Domain=AskToCore.ATMessageComposeValidationError Code=4 'The user is in a region that does not support this type of ask.' UserInfo={NSLocalizedFailureReason=The user must be in a supported region to use this feature., NSLocalizedRecoverySuggestion=Please ensure the user is in an eligible region., NSLocalizedDescription=The user is in a region that does not support this type of ask.}"
I am indeed not in the Texas region.
I want to conduct full-process testing before the feature is released to the App Store.
What should I do?
Apart from Sandbox testing (which, in fact, doesn't show any pop-ups either), how can I test under real-world conditions?
Hi everyone,
We’re testing the new iOS 26 capability, Performing Fast Account Creation with Passkeys, using the sample project provided here: Performing Fast Account Creation with Passkeys.
When running the project on the iOS 26 simulator and tapping the "Sign Up" button, we encounter the following error:
The operation couldn’t be completed. (com.apple.AuthenticationServices.AuthorizationError error 1010.)
From the header file, this error is described as:
/// ASAuthorizationError.h
/// This error signals that the device is not currently set up to create passkeys.
ASAuthorizationErrorDeviceNotConfiguredForPasskeyCreation AS_API_AVAILABLE(ios(19.0), macos(16.0), visionos(3.0)) = 1010,
We’ve tested this on both Xcode 26 Beta 1 and Beta 2, and the error persists on the simulator in both versions.
However, when testing on a physical iOS 26 device, everything works as expected, just like in the WWDC demo.
Could this issue be related to missing simulator settings? Or is it a potential bug in the simulator? Any advice would be greatly appreciated.
Thanks in advance!
We recently integrated MetricKit into our app; however, the 90th percentile data does not seem to match the data in Xcode Organizer. The values reported by MetricKit appear to be higher. Additionally, it looks like data for previous app versions is not being updated in Organizer as adoption of the latest version increases.
Has anyone else experienced this issue? Could there be a delay in data updates for older versions in Organizer? Are there any known limitations or best practices for ensuring consistency between MetricKit and Xcode Organizer data? Any guidance would be greatly appreciated.
I'm trying to upload an update to an iOS app. Xcode goes through the usual dialogue and then immediately gets stuck on "Sending Analysis to App Store Connect..."
Since the Xcode GUI doesn't provide any helpful information, I looked in Console. I can see Xcode completing an SSL handshake, then reporting that it "received viability advisory", followed by boringssl_context_handle_fatal_alert "level: fatal, description: bad record mac". After this it starts the SSL handshake again. It will cheerfully do this round and round forever without ever reporting a problem to the user.
I found a similar post, which has one response about stripping bitcode from libraries (with no explanation as to why this would help), but my app does not include bitcode.
I've updated to the latest version of Xcode incase there was some incompatibility, and rebuilt my app because, while that should be irrelevant to an SSL handshake, I'd expect someone to ask.
Does anybody know what is going on and how to fix it?
does anyone know where to find some slideshow/text/pdf versions of these?

maybe apple can use that fancy AI they are working on to generate those from the vides... to stress-test the AI :)

Hi,
We use Flat package installers (.pkg based installers) to install our applications on macOS. In macOS 26.1, installation is failing with the error
Unable to use PK session due to incompatible packages. Terminating. 2025-11-03 14:22:36+05:30 Admin-3 installer[1160]: Install failed: The Installer could not install the software because there was no software found to install.
Same installer package is working on macOS 26.
Any help is greatly appreciated.

I would like to create iOS App that have MTP-USB functions.
So I have the following questions:
1.Is it possible to create an application with MTP-USB function using .NET MAUI?
2.If 1. is possible, how should I implement it?
The devices I plan to use are iPhone 15 and iPhone 15 Pro.
Thanks.
Here's a simple C++ program that echoes its arguments...
#include <stdio.h>
int main(int argc, char* argv[])
{
for (int i=0; i<argc; ++i) printf("%d %s\n", i, argv[i]);
}
This works as expected...
> ./test arg1 #arg2 arg3
0 ./test
1 arg1
2 #arg2
3 arg3
Running under lldb gives this...
> lldb ./test arg1 #arg2 arg3
(lldb) target create "./test"
Current executable set to '/Users/richard/Work/test' (arm64).
(lldb) settings set -- target.run-args "arg1" "#arg2" "arg3"
(lldb) run
Process 6138 launched: '/Users/richard/Work/test' (arm64)
0 /Users/richard/Work/test
1 arg1
Process 6138 exited with status = 0 (0x00000000)
I get the same if I quote the arguments, or if I add them to the run line. Stepping into main() we see the argv and args values are as though we only had the first argument. If I quote the second argument and add an initial space " #arg1" then it works.
I first saw this on an M1 running Sequoia 13.1. It am now on OS 13.3.
lldb --version
lldb-1600.0.39.109

Hello All,
I used to own an app named LOLIIPOP, and am in the process of transferring it to my new apple account.
I am having two problems....
How do I transfer the source code and binary to my new apple account?
My developers have an old code, so I need to send them the LAST code they uploaded to the App Store.
How do I do that as well???
Please any help!!!
Thanks,
Mr. LM

There was a time that Apple Developer Documentation provides a filter to show the changes across versions, at https://developer.apple.com/documentation/technologies , with purple (modified), green (added), and red (deprecated) annotations.
I wonder if this feature is completely removed, or is it still hiding somewhere? It is helpful to diff the API changes among versions. Thanks.
edit: as pointed out by Rick, here is an archive link to what it used to look like
I need to automate updating to latest iOS betas as part of my ci script, but I can't get it to install iOS 26.0 beta for the life of me, using xcodes or xcodebuild.
I can see the version listed using xcodes runtimes --include-betas, and I tried sudo xcodes runtimes install "iOS 26.0-beta1", but I would get the error
Downloading Runtime iOS 26.0-beta1: 0%
Error: ProcessExecutionError()\
I also tried xcodebuild -downloadPlatform iOS -buildVersion 23A5260l, where I found the specific build id on apples dev images website. But I would get the error
iOS 23A5260l is not available for download.
Specific version download failed, trying downloadPlatform ios latest...
And similar error for trying xcodebuild -downloadPlatform iOS -buildVersion 26.0 or other version ids I found online. But this command would work for any other versions and betas listed on the website.
I was able to install iOS 26.0 through xcodebuild -downloadPlatform iOS, which automatically installed it for me, but this is unideal for my situation, as I want to control which betas to install instead of just the latest one (like iOS 18.6 beta that just came out).
Is anyone else also struggling with these errors?
xcodes version 1.6.2 Xcode version 26.0 Beta (installed and selected through xcode)
In SF Symbols 7 (115), there are 458 symbols missing Availability info. I only discovered this after using one that didn’t appear in iOS 18 but does in iOS 26.
Questions:
Are there plans to add Availability info for all symbols?
If the field is blank, is there a safe latest-OS version we can assume?
I realize managing 7,000+ icons is tough, but missing info like this makes development frustrating. It doesn't help that there's no build warning when a named image isn't found, it just defaults to the text label.
Screenshot

Hi, I'm investigating what looks like possibly nondeterministic behavior when linking large iOS app binaries. I do not have a concise reproduction of the issue yet, but am trying to hunt down possible leads. In particular, the problem appears to surface when invoking clang to link a binary and the resulting order of the 'branch island' instructions appears to be random each time the binary is linked (as shown by the link map output). I was wondering if anyone with insight into the linker's current implementation could shed light on whether that is expected, and if there is anything that can be done to prevent it. FWIW, it seems like it might be size-dependent as smaller app binaries don't appear to exhibit the same behavior. I'd be glad to share more specifics and hopefully a reproduction if I can ever find one eventually. Some environment info (Xcode 16.4 toolchain):

Hello Apple Developer Support,
I am writing to seek assistance with an issue we are experiencing in our SwiftUI application concerning UI test cases.
Our application uses accessibility labels that differ slightly from the display content to enhance VoiceOver support. However, we have encountered a problem where our UI test cases fail when the accessibility label does not match the actual display content.
Currently, we are using accessibility identifiers in our tests, but they only retrieve the accessibility label, leaving us without a method to access the actual display content. This discrepancy is causing our automated tests to fail, as they cannot verify the visual content of the UI elements.
We would greatly appreciate any guidance or solutions you could provide to address this issue. Specifically, we are looking for a way to ensure our UI tests can access both the accessibility label and the actual display content for verification purposes.
For ex:
Problem scenario - setting accessibilityLabel masks access to any displayed content
If an accessibilityLabel is set on a UI element, then it seems to be no-longer possible to check/access the displayed content of that element:
var body: some View {
Text("AAA")
.accessibilityIdentifier("textThing")
.accessibilityLabel("ZZZ") // Different label from the text which is displayed in UI
}
// in test...
func test_ThingExists() {
XCTAssert(app.staticTexts["AAA"].exists) // Fails, cannot find the element
XCTAssertEqual(app.staticTexts["ZZZ"].label, "AAA") // Fails - '.label' is the accessibilityLabel, not the displayed content
XCTAssertEqual(app.staticTexts["ZZZ"].label, "ZZZ") // Passes, but validates the accessibility content, not the displayed content
XCTAssert(app.staticTexts["textThing"].exists) // Passes, but does not check the displayed content
XCTAssertEqual(app.staticTexts["textThing"].label, "AAA") // Fails - '.label' is the accessibilityLabel, not the displayed content
XCTAssertEqual(app.staticTexts["textThing"].label, "ZZZ") // Passes, but validates the accessibility content, not the displayed content
}
element.label still only checks the accessibilityLabel. There is not, it seems, an way back to being able to check the content of the Text element directly.
Thank you for your attention and support. We look forward to your valuable insights.
Question:
I have created a workspace containing a SwiftUI app and two frameworks:
B Framework: Handles UI components
C Framework: Handles service classes
I added a Podfile to manage dependencies. My Podfile is structured as follows:
inhibit_all_warnings!
workspace 'ABC.xcworkspace'
def shared_pods
# Shared pods here
pod 'Alamofire'
end
target 'A' do
use_frameworks!
project 'A/A.xcodeproj'
shared_pods
end
target 'B' do
use_frameworks!
project 'B/B.xcodeproj'
shared_pods
end
target 'C' do
use_frameworks!
project 'C/C.xcodeproj'
shared_pods
end
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.0'
end
end
end
After installing pods and building the project, everything works fine except for Xcode’s SwiftUI Preview, which crashes with the following error:
xcpreviewagent crashed because Alamofire.framework is missing
Question:
How can I resolve this issue and make SwiftUI Previews work without Xcode crashing?
In the beta of Icon Composer, I see macOS, iOS, and watchOS icons, but there is nothing about visionOS and tvOS. Those icons are particularly hard and it would be great if this app worked for developing icons for all Apple platforms.
I tried asking this in a WWDC group lab, but they didn't get to it and suggested posting to the forum.

Hello,
I'm trying to use multiple Background Assets Packs to host map tiles.
This is problematic for a few reasons.
MKTileOverlay requires a method that returns a URL.
AssetPackManager.shared.url() throws, but it's unrelated to the url. It will return a URL even if it points to nothing.
There's no name-spacing. Everything appears to be flattened. (See Error below)
Simultaneously, this also is not the case as the documentation states: if there’s a path collision across multiple asset packs, then it’s undefined from which asset pack an individual file will be resolved.
AssetPackManager.shared.url() doesn't have an optional parameter to explicitly declare the asset pack you want to access, like AssetPackManager.shared.contents(at: FilePath) does
For example, I have multiple different tiles I'm trying to overlay for z: 10, x: 239, and y: 414.
Foo/10/239/414.png
Bar/10/239/414.png
And even when explicitly stating the fold directory, it appears that the assets are flattened down. As I'm receiving this error.
The URL for “Foo/10/239/414.png” couldn’t be retrieved: “414.png” couldn’t be copied to “239” because an item with the same name already exists.
