Overview

Hello. I have issue with implementing "Sign in with Apple" on my website. As folow, I have created: App ID identifier: com.livnobus.app (G2F5N5UHYZ) Service ID identifier: com.livnobus.client (B25ZN8P84U) with option enabled "Sign in with Apple" and configuration (Primary App ID and Webiste URLs) Key ID: 43N8XKUW7S with option enabled "Sign in with Apple" and configuration (Primary App ID and Grouped App Ids) When I click "Sign in with Apple" on my website (https://dev.livnobus.com/auth/login), system redirect me to https://appleid.apple.com/ and error show "invalid_client". Redirect URL on my web site is: https://appleid.apple.com/auth/authorize?client_id=com.livnobus.client&redirect_uri=https%3A%2F%2Fdev.livnobus.com%2Fauth%2Fapple%2Fcallback&scope=name%20email&response_type=code&response_mode=form_post&state=eGAgdpLrvskJc26RbTizc9TGwxnL6KAEJOf68pmO&nonce=e7c7a242-1977-47ea-9013-98820c24bfba.eGAgdpLrvskJc26RbTizc9TGwxnL6KAEJOf68pmO There was old Service ID identifier com.livnobus.app-client, for which I lost private KEY, so I have created new one: com.livnobus.client With old Service ID com.livnobus.app-client, https://appleid.apple.com/ shows me Apple form for sign in, but with new Service ID com.livnobus.client there is error "invalid_client" https://appleid.apple.com/auth/authorize?client_id=com.livnobus.app-client&redirect_uri=https%3A%2F%2Fdev.livnobus.com%2Fauth%2Fapple%2Fcallback&scope=name%20email&response_type=code&response_mode=form_post&state=eGAgdpLrvskJc26RbTizc9TGwxnL6KAEJOf68pmO&nonce=e7c7a242-1977-47ea-9013-98820c24bfba.eGAgdpLrvskJc26RbTizc9TGwxnL6KAEJOf68pmO These changes I have made last Friday, and since then I can't use "Sign in with Apple" on my website. Thanks!

I am having trouble with one of my apps that will not let me log in via Apple Sign In. I am using Firebase and Firebase UI for the sign in process. I have many other apps with the same exact config that currently work just fine, but this one I have gone as far as completely deleting the targets and rebuilding and it will not return from the login screen I checked the following: Sign in with Apple ID Capability is available in XCode and on the dev certificate on developer.apple.com I have also toggled both of them on and off. I have double checked the config in Firebase to turn on the Apple Login identifier. Again I have toggle it on and off. I have cleaned the project multiple times to no avail. I have logged out and back into my developer account in XCode. It seams like after I put in the correct password to log in, it just never returns to the app, there is no logging. I do get a notified(shaking input box) if I put in an incorrect password, but when I put in the correct one, the login window never dismisses and my app is not notified. I checked the Console and the last message from akd on a working app is: Notifying client (bundle) of credential state change 1. Remote view sent a finish event On the one not working, using the same user and password akd returns: SRP authentication with server failed! Error: Error Domain=com.apple.AppleIDAuthSupport Code=2 "M2 missing (bad password) I have 100% verified I am putting in the correct user password. I was only notified of this issue because Policy is having the same issue logging in during App Review. Also, if I put in a bad password the input window shakes and when this is happening, the input window is not shaking

Hi, What's the best way to handle drastic changes in scene charateristics with the new MTLFXTemporalDenoisedScaler? Let's say a visible object of the scene radically changes its material properties. I can modify the albedo and roughness textures consequently. But I suspect the history will be corrupted. Blending visual information between the new frame and the previous ones might be a nonsense. I guess the problem should be the same when objects appear or disappear instantly. Is the upsacler manage these events for us (by lowering blending), or should we use the reactive or the denoise strength mask or something like that to handle them?

After updating to the iOS 26 Beta version, the screenshot option within the AssistiveTouch menu has stopped working. Tapping on the "Screenshot" icon does not perform any action.

Dear Apple Team, I am reaching out regarding the need for more sophisticated location verification APIs beyond basic IP lookup capabilities. As online fraud continues to evolve, IP-based geolocation has proven insufficient for many business use cases requiring accurate location verification. Would it be possible to discuss this proposal with your API development team? I believe this would be valuable for the entire iOS and macOS developer ecosystem while maintaining Apple's commitment to user privacy.

"Use location, address and addressRepresentations instead" Is it possible to know what kind of "Address" a MapItem is representing (State, County, Neighborhood etc) after a MKGeocodingRequest? Is it possible to find out the CLRegion or similar of an map item. (Now when we cannot read it from the Placemark)

I am developing a navigation application. My goal is for this navigation app to also work in the background and provide the user with real-time directional updates. When apps request access to location services, users see a TCC (Transparency, Consent, and Control) prompt. This prompt allows the user to choose under what conditions the app can access location services (for example: “While Using the App”, “Always”, etc.). If the user selects the “While Using the App” option, can the navigation app still access location in the background and provide directional information to the user? Is something like this technically possible? Does Apple allow this behavior for navigation apps or similar use cases?

I haven’t been able to get this to work at any level! I’m running into multiple issues, any light shed on any of these would be nice: I can’t implement a bloom filter that produces the same output as can be found in the SimpleURLFilter sample project, after following the textual description of it that’s available in the documentation. No clue what my implementation is doing wrong, and because of the nature of hashing, there is no way to know. Specifically: The web is full of implementations of FNV-1a and MurmurHash3, and they all produce different hashes for the same input. Can we get the proper hashes for some sample strings, so we know which is the “correct” one? Similarly, different implementations use different encodings for the strings to hash. Which should we use here? The formulas for numberOfBits and numberOfHashes give Doubles and assign them to Ints. It seems we should do this conversing by rounding them, is this correct? Can we get a sample correct value for the combined hash, so we can verify our implementations against it? Or ignoring all of the above, can we have the actual code instead of a textual description of it? 😓 I managed to get Settings to register my first attempt at this extension in beta 1. Now, in beta 2, any other project (including the sample code) will redirect to Settings, show the Allow/Deny message box, I tap Allow, and then nothing happens. This must be a bug, right? Whenever I try to enable the only extension that Settings accepted (by setting its isEnabled to true), its status goes to .stopped and the error is, of course, .unknown. How do I debug this? While the extension is .stopped, ALL URL LOADS are blocked on the device. Is this to be expected? (shouldFailClosed is set to false) Is there any way to manually reload the bloom filter? My app ships blocklist updates with background push, so it would be wasteful to fetch the filter at a fixed interval. If so, can we opt out of the periodic fetch altogether? I initially believed the API to be near useless because I didn’t know of its “fuzzy matching” capabilities, which I’ve discovered by accident in a forum post. It’d be nice if those were documented somewhere! Thanks!!

Hello, I'm working on an application that requires the use of significant location changes and visits, in addition to region monitoring and standard continuous location delivery (foreground and background). iOS 17 and iOS 18 introduced changes to how we can monitor distinct regions of interest (with CLMonitor) as well as receive location updates (with CLLocationUpdate). But I couldn't find any information regarding how to work with Significant location changes. Do we still need to create a location manager and call startMonitoringSignificantLocationChanges()? Where are the updates received in this case, in the locationManager(_:didUpdateLocations:) or in the liveUpdates async sequence? Visits. Same question here, for visit monitoring to work, do we still have to create a location manager then call startMonitoringVisits()? Where are the visits being notified? Still in locationManager(_:didVisit:) or in the liveUpdates asynchronous sequence? I just want to be sure I understand correctly how to use the updates, and if some features of Core Location still need to use a location manager and the delegate to receive the events. Maybe additional CLCondition will be added to cover both of these technologies as it seems highly related to monitoring conditions (significant location change, and visit). Thank you, Axel

Hi Community, We've implemented Sign In with Apple in our application. Our domains are properly registered in the developer console, but we're experiencing inconsistent email functionality with Apple's privacy email service. Some domains work correctly while others show delivery problems, even though all domains have identical configurations. Apple's console displays green verification status for all domains, yet testing reveals that emails to privacy-protected accounts don't arrive as expected. We're using SendGrid as our email service provider, and all domains have valid authentication records (SPF, DKIM, DMARC) in place. Has anyone encountered similar inconsistencies with Apple's privacy email service? Would appreciate any configuration tips or troubleshooting guidance. Thanks.

Hi, We’re developing a DriverKit extension for iPadOS. In local Debug and Release builds, everything works as expected, but the same build uploaded to TestFlight fails at IOServiceOpen with the following errors: -536870212 (0xE00002EC) kIOReturnUnsupported -536870201 (0xE00002F7) kIOReturnNotPermitted What we’ve verified so far App entitlements We checked our main app entitlements file, and it has the correct capabilities for the driverkit communication <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.developer.driverkit.communicates-with-drivers</key> <true/> <key>com.apple.developer.driverkit.userclient-access</key> <array> <string>abc.def.ABCDriver</string> </array> <key>com.apple.developer.system-extension.install</key> <true/> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.device.usb</key> <true/> <key>com.apple.security.files.user-selected.read-write</key> <true/> </dict> </plist> we also checked the Provisioning profile (as shown on the portal) and the “Enabled Capabilities” seems to have the correct DriverKit Capabilities enabled.

Why do some DriverKit capabilities appear in the Apple Developer portal UI but vanish from the actual profile we download? Is there an extra step we’re overlooking when regenerating profiles after toggling those capabilities? Thanks

Our Indoor Map for shopping center has been stuck at "Occupants Data in Review" for a few weeks. Can someone on that team assist? Thank you.

Hi, I want to detect if there is a fullscreen window on each screen. _AXUIElementGetWindow and kAXFullscreenAttribute methods work, but I have to be in a non-sandbox environment to use them. Is there any other way that also works? I don't think it's enough to judge if it's fullscreen by comparing the window size to the screen size, since it doesn't work on MacBook with notch, or the menu bar is set to 'auto-hide'. Thanks.

I work on a universal app that targets both iPhone and iPad. Our iPad app currently requires full screen. When testing on the latest iPadOS 26 beta, we see the following warning printed to the console: Update the Info.plist: 1) `UIRequiresFullScreen` will soon be ignored. 2) Support for all orientations will soon be required. It will take a fair amount of effort to update our app to properly support presentation in a resizable window. We wanted to gauge how urgent this change is. Our testing has shown that iPadOS 26 supports our app in a non-resizable window. Can someone from Apple provide any guidance as to how soon “soon” is? Will UIRequiresFullScreen be ignored in iPadOS 26? Will support for all orientations be required in iPadOS 26?

Hi- I've never posted on here before! But ChatGPT hasn't been helpful with this. I have a call using MKLocalSearch (i have a waddled down version below) let region = MKCoordinateRegion( center: location, // the user's location span: MKCoordinateSpan( latitudeDelta: 0.005, longitudeDelta: 0.005 ) ) let req = MKLocalPointsOfInterestRequest(coordinateRegion: region) req.pointOfInterestFilter = MKPointOfInterestFilter(including: [.nightlife]) let search = MKLocalSearch(request: req) I made the latitude and longitude the lowest they can possibly be without throwing an error. Sometimes (and unreliably) when the user's location is at say, a bar, this list will give me like 10 bars that are not even within the region, and exclude the bar that the user is actually present in. How can i make this not the case? In other words, I just want this to return what I expect: a list of POIs with the category .nightLife within the defined region. Any help would be appreciated!

As I had mentioned earlier, I was facing two issues after the initial update, but I’m happy to inform you that both of those issues have now been resolved. However, after updating to iOS 26.0 (23A5297m), I’ve started experiencing a new issue related to overheating. Since yesterday, my iPhone has been getting extremely hot while charging. It also became very hot after clicking just a few photos. The same heating issue occurred again today during charging. This problem only started after the latest update. Kindly look into this issue and advise on how to resolve it.

I have two applications, and I recently decided to add the Apple Sign In feature. Initially, I configured it for one of the apps as the Primary ID for this feature. Everything worked well, and I decided to add it to the second app. I made a mistake and used the First app as Primary ID using the "Group with an existing primary App ID" flag. Now, when I sign in using the second app, I don't see it in the list of apps in iPhone Settings for Apple Sign In; I only see the primary app. And with that, I no longer see a prompt for sharing/hiding email, and I am unable to revoke credentials correctly. I decided to change the Second app's Sign-in config and set it as the Primary ID for the feature. I was hoping to get two apps independent for the SignIn. However, it doesn't seem to make a difference. The second app behaves the same way, as long as the first app used SignIn, the second one always thinks that the user has already used that feature and never shows the correct prompt. Is there something I missed after changing the Configuration?

Background: For iOS, I have built a custom video record app that records video at the highest possible FPS (supposed to be around 240 FPS but more like ~200 in practice). When I save this video to the user's camera roll, I notice this dynamic playback speed bar. This bar will speed up or slow down the video. My question: How can I save my video such that this playback speed bar is constantly slow or plays at real time speed? For reference I have include the playback speed bar that I am talking about in the screenshot, you can find this in the photo app when you record slow motion video.

[Also submitted as FB19313064] The .disabled() modifier doesn't visually disable buttons inside a ToolbarItem container on iOS 26.0 (23A5297i) devices. The button looks enabled, but tapping it doesn't trigger the action. When deployment target is lowered to iOS 18 and deployed to an iOS 18 device, it works correctly. It still fails on an iOS 26 device, even with an iOS 18-targeted build. This occurs in both the Simulator and on a physical device.
