How are Assets removed?
Hello, I'm trying to figure out the behavior of AssetPackManager.shared.remove(assetPackWithID: ). I'm working with MapKit tiles and currently working on trying projecting them correctly which involves serving the AssetPack locally, downloading, checking alignment, and then deleting and changing. My question is that remove(assetPackWithID: ) completes successfully and the asset pack is removed. This is confirmed by trying to remove the AssetPack again which throws an error. However, the asset is still appearing on MapKit after the removal. This is a bit odd as this persists not only with force killing, but also restarting the device. Please advise on how to properly remove an AssetPack. Thank you iPhone 15 Pro Max (iOS 26.0.1) iPhone 17 Pro Max (iOS 26.0.1)

Reply to Foundation Models Framework with specialized models
You can add your own model with MLX. I've used MLX_LM.lora to 'upgrade' Mistral-7B-Instruct-v0.3-4bit with my own content. The 'adapter' folder that is created can be added to the original model with mlx_lm.fuse and tested with mlx_lm.generate in the Terminal. I then added the resulting Models folder into my macOS/iOS Swift app. The app works on my Mac as expected. It worked on my iPhone a few days ago but now crashes in the simulator. I don't want to try it my phone until it works (again) on the simulator. The models folder contains the files created by the fuse command. I'm not sure that I changed anything in the last few days but it seems to be crashing in the loadmodel function with a lot of 'strange' output that I don't understand. My loadModel func `func loadModel() async throws -> Void { // return // one test for model not loaded alert // Avoid reloading if the model is already loaded let isLoaded = await MainActor.run { self.model != nil } if isLoaded { return } let modelFactory = LLMModel

Change popover background color in iOS 26
Is it not possible to change the background color of popovers in iOS 26? The backgroundColor property of UIPopoverPresentationController seems to just get ignored when Liquid Glass is enabled. Here’s a minimal repro: let presentedVC = UIViewController() presentedVC.modalPresentationStyle = .popover presentedVC.view.backgroundColor = .clear let popover = presentedVC.popoverPresentationController popover?.sourceItem = button popover?.backgroundColor = .red present(presentedVC, animated: true) If the UIDesignRequiresCompatibility key is set to YES, then the popover background color works as expected.

watchOS 26.0.2 / iOS 26.0.1 + Workout Session Mirroring Failure
Hi, I have a workout app in the App Store which mirrors workout data between the phone and watch. Since iOS 26.x I've been having issues and received reports of the mirroring no longer working. Users in iOS 18 have no problems with this functionality. Bug description: A workout session is started from the phone app and starts mirroring to the watch companion device. The watch starts the workout session and then the mirroring session is disconnected / lost. Sending data to the companion device fails and ending the session on the phone doesn't end the session on the watch...essentially they become completely disconnected. Please note I am testing this on physical devices...not simulators. As a sanity check I've also tried the Building a multidevice workout app sample code and it has the same problem. To re-create on the sample app, I start a workout from the phone, the watch workout starts and then the mirroring session seems to disconnect and is unable to send data. This is the log from the B

CallKit does not activate audio session with higher probability after upgrading to iOS 18.4.1
Hi, We've noticed that this issue occurs more frequently after upgrading to iOS 18.4.1 and can result in one-way audio. Our app uses CallKit with WebRTC to establish VoIP connections. However, on iOS 18.4.1, CallKit no longer triggers: func provider(_ provider: CXProvider, didActivate audioSession: AVAudioSession) We're currently comparing the occurrence rate across different iOS versions to better understand the impact. Could you please help analyze the root cause of this issue?

Reply to CallKit does not activate audio session with higher probability after upgrading to iOS 18.4.1
One bit of follow-up on the bug fix side of this: FB19429215 (CallKit does not activate audio session with higher probability after upgrading to iOS 18.4.1) Having looked into the issue in more depth, there are technical issues that are likely to delay a fix coming from our side. The CallKit team is still committed to resolving this, but you should not expect the issue to be resolved in the short term. I'll also say that, based on my own analysis, I do NOT think this is in fact a new issue. That is, going back to the original report on this thread: We've noticed that this issue occurs more frequently after upgrading to iOS 18.4.1 The focus here was on the increased rate; however, it's very likely that this was simply a shift in the rate an existing bug occurred, NOT a new/different issue. Because of that, my recommendation is that all CallKit apps send a setConfiguration immediately before they report a new call. It's the best way I can see to prevent the problem from occurring and is alread

Reply to Background abnormal exit on iOS 26
Hello, This is most likely due to the analytics self-correcting after terminations were previously under-reported due to a bug. Please see the Xcode section in the iOS 26 release notes: https://developer.apple.com/documentation/ios-ipados-release-notes/ios-ipados-26-release-notes Thanks!

Reply to Change popover background color in iOS 26
Thanks for the post. Do you get the same results with just the relevant code in a small test project? If so, please share a link to your test project. That'll help us better understand what's going on. If you're not familiar with preparing a test project, take a look at Creating a test project. If you could provide me with the sample, I can test it myself. However, if this is a bug, are you testing it with different versions of iOS? Let’s get to the bottom of the issue! Albert Pascual

Reply to Profile doesn't include the com.apple.application-identifier entitlement.
I experienced this problem in XCode 26.0.1. My app has a single target configured with iOS and macOS destinations. For macOS, my app requires the sandbox entitlement for calendar data access. I fixed the error by: Removing the com.apple.application-identifier, com.apple.security.app-sandbox, and com.apple.security.personal-information.calendars entries from the app's AppName.entitlements file. Adding the sandbox and calendar entitlements back by adding the corresponding capabilities in the app target Signing & Capabilities settings. Toggling off and back on Automatically manage signing. I believe this worked because sandbox capability entitlements are only injected for macOS, while entitlement file entitlements were injected for all destinations. Hopefully this helps others with similar dual-destination setups.

Profile doesn't include the com.apple.application-identifier entitlement.
I have tried everything and still I am getting this. Just for a test I created a new app (Master-Detail template Xcode 11.5) I have created an entry in the iTunes Connect to receive the app upon archiving and uploading. I regenerated all new certificates for iOS Development and Distribution. I created all new Provisioning profiles. The Dev profile builds deploys and runs on my device The Dist profile builds but when I select the distribution profile I get the Profile doesn't include the com.apple.application-identifier entitlement. error. When I download the profile within Xcode all looks good for the distribution profile: App ID: matches correctly Certificated: 1 Included includes the new signing certificate iPhone Distribution.... Capabilities: 3 Included Includes Game Center, In-App Purchase, and Keychain Sharing Entitlements: 5 Included Includes application-identifier, keychain-access-groups, beta-reports-active, get-task-allow, and com.apple.developer.team-identifier.

Impossible to connect iPhone 7 (iOS 15.8) with xCode 26
I have spent nearly an hour trying to get my iPhone 7 with iOS 15.8 to be recognized within xCode 26. I did not have this issue with the previous version of xCode. I have tried rebooting my Mac, rebooting my iPhone 7, removing the iPhone 7 from the list of devices that belong to my account, verified that I have support files for iOS 15.8 installed, signing out of my Apple account and signing back in....nothing works. Every time I go to Windows > Devices I see the iPhone 7, but I get a never-ending spinning circle next to the iPhone 7 (which is shown as connected) along with a banner that says xCode will continue when Joe's iPhone 7 is finished. I can leave the phone connected to my Mac for an hour, and this message and the spinning circle next to the iPhone 7 never changes.
