Certainly! Here's a concise version of your forum post: Title: Issues Handling Multiple Incoming Calls in CallKit Body: Hello, I'm using CallKit and I am encountering challenges with handling multiple incoming calls. Current Configuration: configuration.maximumCallsPerCallGroup = 5 configuration.maximumCallGroups = 3 This setup aims to allow up to 5 calls per group. Observed Behavior: Despite the configuration, the system UI seems to limit the number of calls per group, often defaulting to "End & Accept" instead of "Hold & Accept" when a third call comes in. Questions: Is there a documented system-imposed limit on the number of calls per group or total calls, even if maximumCallGroups and maximumCallsPerCallGroup are set higher? How does the system UI behave when these limits are exceeded? Are there known UI constraints or fallback behaviors? Are there best practices for handling scenarios where the system UI cannot display all calls, such as gracefully managing incoming calls or providing alternative UI solutions? Any insights or experiences with similar configurations would be greatly appreciated. Thank you. Feel free to copy and paste this directly into the Apple Developer Forums. If you need further assistance or adjustments, let me know!

On iOS 18 and lower version, my application supports automatically switching to [System settings - Personal Hotspot] directly. But on iOS 26, my application will be redirected to [System settings- Apps]. Does iOS 26 disable the behavior of directly jumping to the system hotspot page? If support, could you share the API for iOS 26?

On macOS 26, I've run into a situation when a user “customizes” a folder icon with Finder by assigning/changing an SF Symbol or an emoji, QLThumbnailGenerator keeps returning the stale initially retrieved folder icon (no matter whether it had been customized or not) until my app quits. After the app is re-launched, the icon is correctly retrieved once again. let generator = QLThumbnailGenerator.shared let size: CGSize = CGSize(width: 64, height: 64) let request = QLThumbnailGenerator.Request(fileAt: url, size: size, scale: NSScreen.main!.backingScaleFactor, representationTypes: .icon) request.iconMode = true do { let thumb = try await generator.generateBestRepresentation(for: request) thumb.nsImage.size = size return thumb.nsImage } catch { print("generateThumbnail: \(error)") return nil } It seems like the QuickLook Thumbnailing cache does not invalidate automatically upon folder customization. Is there any way to manually invalidate the QuickLook Thumbnailing cache?

Hi Guys, I've been wanting to make a bettermouse-like tool for some time now, but I can't figure out how to modify mouse events to do it. I've managed to get mouse events, like the cursor moving, but I can't seem to modify them. What I try either creates a feedback loop, does absolutely nothing, or makes the cursor have a seizure. Any help is appreciated!

Hi, I’ve built an app that includes a Contacts Provider Extension (CPE). On iOS 18, I observed the expected behavior — when the main app is uninstalled, the corresponding CPE entry is also removed from the Contacts list. However, on iOS 26, this no longer happens. After uninstalling the app, the CPE remains visible and active in the Contacts list, even though the app is gone.

I'm implementing the PushToTalk framework and have encountered an issue where channelManager(_:didActivate:) is not called under specific circumstances. What works: App is in foreground, receives PTT push → didActivate is called ✅ App receives audio in foreground, then is backgrounded → subsequent pushes trigger didActivate ✅ What doesn't work: App is launched, user joins channel, then immediately backgrounds PTT push arrives while app is backgrounded incomingPushResult is called, I return .activeRemoteParticipant(participant) The system UI shows the speaker name correctly However, didActivate is never called Audio data arrives via WebSocket but cannot be played (no audio session) Setup: Channel joined successfully before backgrounding UIBackgroundModes includes push-to-talk No manual audio session activation (setActive) anywhere in my code AVAudioEngine setup only happens inside didActivate delegate method Issue persists even after channel restoration via channelDescriptor(restoredChannelUUID:) Question: Is this expected behavior or a bug? If expected, what's the correct approach to handle incoming PTT audio when the app is backgrounded and hasn't received audio while in the foreground yet?

Issue with App Clip Card Showing "App Clip unavailable" for DIGI LIVE App In my DIGI LIVE application, I have an App Clip configured for iOS 17.6+ (the file exceeds the 15 MB limit), and I have made all the necessary preparations for the App Clip to work correctly. However, the App Clip card constantly displays an "App Clip unavailable" error for various users (depending on their system language). The URL associated with the App Clip invocation is: https://ar.digi-live.de The AASA file is located at /.well-known/apple-app-site-association and contains the required fields for the App Clip: { "applinks": { "details": [ { "appIDs": ["N9QR6LF765.de.digilive.app"], "components":[ { "#": "no_universal_links", "exclude": true, "comment": "Matches any URL whose fragment equals no_universal_links and instructs the system not to open it as a universal link" }, { "/": "*", "comment": "Matches any URL like ar.digi-live.de" } ] } ] }, "appclips": { "apps": ["N9QR6LF765.de.digilive.app.Clip"] } } If I use the default App Clip link (https://appclip.apple.com/id?p=de.digilive.app.Clip) to launch it, the "App Clip unavailable" error no longer appears. But if I delete the App Clip from the settings, the error comes back, and it can only be launched again using the default link. It feels like the problem is with the App Clip loading at the moment the App Clip card is triggered — it simply fails to load. Video https://storage.yandexcloud.net/mmrs/files/digilive/IMG_2259.mp4

I implemented AlarmKit framework to my app. It works fine when the device's screen is off. but it doesn't fire when the screen is on. No sound, No dynamic Island widget. what's wrong... is this just me? I tried other apps on appstore and they worked fine. maybe is it cause they were built with SwiftUI? I'm a flutter developer. just cause my app is non native could this happen... I'm so frustrated.

The name of our app is a portmanteau, and Siri is getting it slightly wrong. It’s putting the emphasis on the second and fourth syllables instead of the first and third. Kind of like if someone starting singing /tinˈeɪʒd muˌtent/. It’s just wrong enough to be funny. It still recognizes the correct name when someone says “hey Siri”. We’ve already tried adding CFBundleSpokenName and INAlternativeAppNamePronunciationHint to info.plist, but neither is changing how Siri says it. We can’t put it in AppIntentVocabulary.plist because we don’t know the key path for the app name.

I'm developing a parental control app that needs to block adult/18+ websites using the Screen Time API. I've run into scaling issues with 'ManagedSettings.webContent.blockedByFilter`. Environment: iOS 18.x, real device (iPhone) ManagedSettings framework Screen Time permissions granted Current Behavior: The Question: Commercial parental control apps successfully block tens of thousands of domains. What API or architecture should I be using to scale beyond 30-50 domains? Approaches I'm considering: Safari Content Blockers (limited to Safari only) Multiple ManagedSettingsStore instances Network Extension / DNS filtering A different Screen Time API approach What's the recommended way to block large domain lists (1000-60000+) across all apps and browsers? Any guidance appreciated! //33 domains - Works perfectly let blockedSites: Set<WebDomain> = [ WebDomain(domain: "example1.com"), WebDomain(domain: "example2.com"), // ... 31 more domains ] store.webContent.blockedByFilter = .specific(blockedSites) // All 33 domains blocked successfully // 101 domains - Complete failure (no domains blocked at all) let blockedSites: Set<WebDomain> = [ WebDomain(domain: "example1.com"), // ... 100 more domains ] store.webContent.blockedByFilter = .specific(blockedSites) // No errors thrown, but ZERO domains are blocked

How can experimentation and testing calling the AgeRangeService.shared.requestAgeRange() functionality be recreated easily? The very first time I ran this the OS popped up a dialog, however it won't do so again, even after the app is deleted and the device re-started. If one navigates to Settings/User/Personal Information/Age Range for Apps/Apps that have requested your age range appear here. Then the names of apps appear here even after the app has been deleted. Therefore how can it be removed from this section? Erasing and resetting the phone will presumably reset things back to a state such that the dialog can be presented again. But doing that and having to wait for that to complete each development or test run is impractical. Is there an alternative?

Hi, I am just wondering if there is any option to protect my endpoints that will be used by Message Filtering Extension? According to the documentation our API has 2 endpoints: /.well-known/apple-app-site-association /[endpoint setup in the ILMessageFilterExtensionNetworkURL value of the Info.plist file] that the deferQueryRequestToNetwork will request on every message Since all requests to these 2 endpoints are made by iOS itself (deferQueryRequestToNetwork), I don't understand how I can protect these endpoints on my side, like API key, or maybe mTLS. The only way that I found is white list for Apple IP range. Is there other methods for it?

I am building a screen time management app. It has the main app target, and then three extensions - those are the four targets in Xcode. The three extensions are: Shield Device Activity Monitor Device Activity Report Extension I requested "Family Controls (Distribution)" capability from Apple for the main app target / bundle ID, and it got approved. Do I need it for the extensions too? Because previously I had "Family Controls (Development)" for the extensions...

Hi, I’m trying to open a GPX file (route.gpx) from the Files app on my iPhone using my app (e.g., Aqua Map). Since the latest iOS update (iOS 26), when I long-press the file and tap “Open with…”, my app does not appear in the list anymore. I’ve checked that my app has the correct permissions for Files and Folders. I’m wondering: Is this a user-side issue (Settings on iPhone)? Or does it require developer-side changes in the app (Info.plist / UTI declarations) to make .gpx files appear in “Open with…” or “Share” menus? What is the proper way to make my app appear as an option to open GPX files in Files.app on iOS 26? Thanks in advance!

Explanation of the issue When tethering is enabled and a wireless connection is established, there are instances where an IP address is not assigned. Steps to Reproduce the Issue (if possible) Enable iPhone tethering and connect wirelessly using 11ax. Expected Result The iPhone assigns an IP address, enabling network connectivity. Actual Result Observed DHCP negotiation failed. After attempting communication with the DHCP server via DHCP Discover, a DHCP Offer was returned from the iPhone. If this was missed, it would retry by performing another DHCP Discover. However, the iPhone does not issue a DHCP Offer no matter how many times it retries. The IP address is not assigned unless the wireless connection is disconnected and reconnected. If the initial Discover is missed, does this invalidate subsequent Offer retries? The above issue has been confirmed on iPhone 17 Pro and iPhone 16. It does not appear to occur on iPhone 15.

Hello, Back in January 2024, I filed a bug report regarding a cache being kept by the macOS Wallpaper Agent. This cache contains every image ever set as a users wallpaper, and at the time the issue was reported, it never cleared, leaving hundreds of gigabytes wasted on users disks in some cases. FB13536275 This issue was ultimately fixed in macOS 15.1 beta 6, and remained fixed for the duration of macOS 15. The fix was excellent - the cache was reduced to storing just 2-3 days worth of images. Sadly, we've discovered that this issue is back in macOS Tahoe. The cache has moved locations, and once again is not clearing. We have filed this bug again, less than a year after it was first fixed: FB20636593 We develop an app called 24 Hour Wallpaper that keeps the wallpaper in sync with the time of day. This necessitates that the app regularly changes the wallpaper, which sadly now results in an infinitely growing and useless cache of BMP files generated by the system. As we waited 10 months for this to get fixed the first time, we expect to wait at least that long to get it fixed again, and have no confidence that it will stay fixed because the last fix lasted less than a year. This leaves us in a bad position, as people can't use our app without the cache growing arbitrarily and ultimately completely filling their disk. We've already had customers call Apple to complain about this, and the good news is that the support agents understand that this is a problem with macOS, not with our app. What we've decided to do is add a feature to the app that monitors the size of this cache and periodically deletes it. We're required to get the users permission the first time to do this, but after that the permission is cached, so the app can keep the cache folder clean regardless of if macOS is doing it's job or not. We haven't seen any side effects or problems as a result of doing this. We've seen other apps like CleanMyMac do this without any problems. We're wondering if there is anything we should be aware of regarding this caches behavior before releasing this flushing feature. Thanks for your time, -josh

On macOS, one can set the "Open With ..." application in the information panel of a file without changing the default for this file type. However, doing this for a number of files is very tedious. A simple case is to change all .txt files in a directory to a special editor, but leave the system wide default (usually TextEdit). I have tried AppleScript, command line tools as well as a minimal GUI app (using LSSetItemAttribute), but all fail because of a lack of permission. Is there any way to achieve this?

In recent versions, the increase in background abnormal exits is significant. According to monitoring data, it is closely related to the iOS 26 system. Could you please look into the reasons or provide some suggestions for troubleshooting the issue?
