Hi Team, We’re encountering a device-specific issue with our SMS Message Filter extension. The extension works as expected on an iPhone 11 running iOS 16.6, but it does not trigger on an iPhone 12 Pro running iOS 16.7. Key Observations: The extension is implemented using ILMessageFilterExtension and calls messageFilterOffline(appGroupIdentifier:for:) from our shared library. The App Group is properly configured and accessible across the app and extension. The extension is enabled under Settings > Messages > Unknown & Spam. There are no crashes or error logs reported on the affected device. The issue is consistently reproducible — it works on one device but not the other. We’re wondering if this could be a regression or a device-specific behavior change introduced in iOS 16.7. Has anyone encountered similar inconsistencies in Message Filter extensions across different iOS versions or device models? Any guidance or suggestions would be greatly appreciated. Thanks in advance!

I want decoded my base64 string and want to create image from it. NSData *data = [NSData dataWithBytes:bpData.rt_wav.data length:sizeof(bpData.rt_wav.data)]; NSMutableString *baseString = [data base64Encoding]; UIImage *image = [UIImage imageWithData:data];

We have identified an issue when using NumberFormatter with the locale set to it_IT. Specifically, when formatting numbers with exactly four integer digits, the grouping separator is not applied: for example, the number is displayed as 4000,00 instead of the expected 4.000,00. This behavior occurs only with four-digit integers; for instance, 40.000,00 is formatted correctly. The issue appears to affect only iOS 18.4 and later versions.

Hi there, we are implementing the new ContactProviderExtension introduced in iOS 18 and we are able to activate the extension, add data and everything. But we want to add domains to seperate contacts and currently we are getting an error "ContactProvider.ContactProviderError.domainNotRegistered". That makes sense because in the API docu we are not finding a way to register our domains. We are using ContactProviderDomain to create domains but we are not able to find any function to register. Could you please give a hint? Thank you

In iOS 18 (beta 1-4) when you set openAppWhenRun = false in your AppIntent of your live activity the perform function never gets called. In iOS 16 and 17 my live activities work. I have downloaded other apps and in their live activities any button tab which doesn´t open the app is also doing nothing in iOS 18. Has anyone got this working? Any comments from an Apple engineer on this?

All After about 20 hours straight of working on this and having scrapped it twice I am realizing I should have asked everyone here for help. I am just trying to get device activity report extension to work inside an existing app. I have been heavily using family controls, managedsettings and deviceactivity and decided it would be nice to output some of the app usage so the User (parent) can see their children's app usage. I installed the target via xcode, confirmed group names match, and think I have it embedded correctly but when I run the app and call the view within the extension to show minutes used by any apps it just shows no time has been used. In addition, when I put print statements into the extension they do not show up in console. I have confirmed the main app target->Build phases->Link binary with Libraries has: ManagedSettings.framework FamilyControls.Framework DeviceActivity.framework I have confirmed in xcode that the main app target->Build phases -> Embed Foundation Extensions has: ShieldConfiguration.appex ShieldActionExtension.appex DeviceActivityMonitor.appex I have confirmed in xcode that the main app target->Build phases-> Embed ExtensionKit Extensions has: UsageReportExtension.appex I have used the apps I am trying to show data for extensively in the last 36 hours.

We are planning to use our internal IdP (PingFederate) for authentication of end users in their iOS apps using ASWebAuthenticationSession. Initial tests are successful, but the user is prompted for every login (and logouts) with a consent dialogue box: “AppName” wants to use “internal domain-name” to Sign In This allows the app and website to share information about you. Cancel Continue” Let’s say that our top-level domain is “company.no”, where our IdP is placed at “idp.company.com”. I have seen examples where the Associated domains entitlement points to the idp as a webserver for serving the JSON output AASA file. In this case that would be: authsrv: idp.company.com Anyone with experience implementing this structure with the IdP as webserver for serving the JSON output? Our problem is that trying to use the IdP as webserver for this purpose is that it is very complicated to modify the IdP’s webserver configuration. Also, this modification needs to be re-done every time we need to upgrade the IdP. My question is therefore also related to the options of which webserver to install the AASA file on. Has anyone installed the file on a generic webserver on the toplevel domain like “webserver.company.com” ?

Hello everyone, Our team is currently developing an iOS application requiring real-time audio communication and evaluating the most suitable frameworks. Options include CallKit, custom solutions using AVAudioEngine/Audio Units, and the PushToTalk framework. Regarding the PushToTalk framework, we have some questions about its core design and capabilities that we'd appreciate clarification on from the community or Apple engineers. Based on the PushToTalk framework documentation, its API design (e.g., methods like requestBeginTransmission, endTransmission which imply explicitly requesting transmission rights), and its system UI integration, it strongly appears oriented towards half-duplex communication scenarios, similar to traditional walkie-talkies where only one participant transmits audio at a time. Is this understanding accurate? Is the PushToTalk framework's design strictly limited to managing half-duplex audio interactions? Or, does the framework itself also provide built-in mechanisms or APIs to manage simultaneous, bi-directional (full-duplex) audio streaming between participants? To be clear, we are asking about the inherent capabilities of the PushToTalk framework itself. We understand it's possible to use PushToTalk for signaling and UI management, and separately implement the actual full-duplex audio stream using AVAudioEngine or other audio APIs. However, we want to confirm if the framework itself is designed to support or simplify full-duplex audio communication. Have other developers investigated the specific limitations or capabilities of the PushToTalk framework regarding audio transmission modes (half-duplex vs. full-duplex)? Are there any official documentation references or WWDC sessions that explicitly clarify the framework's support (or lack thereof) for full-duplex operation? If PushToTalk is indeed limited to half-duplex, what are the generally accepted best practices for apps requiring full-duplex calls – transitioning directly to CallKit (where applicable) or building custom audio processing pipelines? Clarifying this point is crucial for us to select the correct technology stack for our application. Any relevant insights, documentation pointers, or shared development experiences would be greatly appreciated. Thank you for your help!

I am working with a watchOS app in SwiftUI, and I am using the following code to dial a phone number from the watch: var number = "123456789" if let telURL = URL(string: "tel:\(number)") { let wkExtension = WKExtension.shared() wkExtension.openSystemURL(telURL) } The issue is that when I try to dial a number starting with a * (asterisk) or # (hash), it doesn't work. When dialing a regular number, it works fine. Is there any way to get this to work?

reposting this in case it got missed the first time around here https://developer.apple.com/forums/thread/775900 We had a question that came up when we comparing data from WeatherKit to other sources - WeatherKit visibility was well beyond the boundaries we had historically, even from Darksky. That raises two questions: is visibility actually in meters like the docs say? is this visibility at ground level, 500ft, or some other height? We were seeing visibility numbers of up to 40 miles (after converting the number the API sent to miles), where all of our other sources are usually within 10 miles

Hi All my app randomly crash on very rare case. when bring app into foreground I checked the code: { NSError *error = nil; if (![sender authenticateWithPassword:MyManager.sharedManager.service.authToken.accessToken error:&error]) { ... ... ... } } accessToken is NSString type, was that because accessToken is deallocated? Manager and service could not be nil at all.

My CoreSpotlight extension seems to exceed the 6 MB memory limit. What’s the best way to debug this? I've tried to attach the debugger on the Simulator but the extension seems to be never launched when I trigger the reindex from Developer settings. Is this supposed to work? On device, I am able to attach the debugger. However, I can neither transfer the debug session to Instruments, nor display the memory graph. So I've no idea how the memory is used. Any recommendations how to move forward? Is there a way to temporarily disable the memory limit since even with LLDB attached, the extension is killed.

Is there any way to find the reason for a CRASHING_DUE_TO_PRIVACY_VIOLATION from a crash report? It does not happen on my old iPad Air 2 and it does not happen on the simulators with the latest iOS. But it crashes always on newer real devices to which I have no access. The last app review for the AppStore also did not find it. I added some privacy strings by guessing and sent it via TestFlight but it doesn't change anything.

Hello. We have an app and a custom dylib hat seems to be crashing only when Rosetta is involved. I believe it's the custom DYLIB that crashes. Here are some observations. The issue happens on the older 2022 built DYLIB (Intel only) And the newer DYLIB built (Universal) The universal DYLIB works fine natively on both Intel and M1 machines. It's only when we access it through an Intel only .app and it's running with Rosetta that we see the crash. The older Intel only .DYLIB worked perfectly with the same testing .app in versions before Sonoma, now they crash with the same .app, same build. Crash reports have been all over the place, they vary but repeat themselves. It has been a little confusing as to how to approach this issue and would appreciate any input that can help us understand what is going wrong and how to move forward. Crash reports are attached Crash Report 1 Crash Report 2 Crash Report 3 The crash occurs as SIGSEGV Version: 2.0 (1) Code Type: X86-64 (Translated) Parent Process: launchd [1] User ID: 501 Date/Time: 2025-04-14 19:55:06.0103 +0200 OS Version: macOS 14.6 (23G5075b) Report Version: 12 Anonymous UUID: A08ECCFA-BF01-8636-7453-E4476586D3A8 Time Awake Since Boot: 3900 seconds System Integrity Protection: enabled Notes: PC register does not match crashing frame (0x0 vs 0x102920144) Crashed Thread: 10 Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x000000011d052840 Exception Codes: 0x0000000000000001, 0x000000011d052840 Termination Reason: Namespace SIGNAL, Code 11 Segmentation fault: 11 Terminating Process: exc handler [3174] VM Region Info: 0x11d052840 is not in any region.

We developed a "Default Translation App" following the guide: https://developer.apple.com/documentation/translationuiprovider/preparing-your-app-to-be-the-default-translation-app. I have already configured everything that needs to be configured according to the document, but there is still this problem

We've been using the WeatherKit API for a few years now. Everything has been pretty stable. We'll periodically get 404 errors, but they usually disappear within a couple days. Starting March 5th we've again been getting 404 errors that slowly ramped up to March 20th and continued. We have had no code changes on our end, so something seems to have changed / broken on the server side of things. Here are some example API calls that are giving us a 404 error now https://weatherkit.apple.com/api/v1/weather/en/35.9981205/-78.8920444?dataSets=forecastDaily&dailyStart=2025-03-21T05:00:00Z&timezone=America/New_York&countryCode=US https://weatherkit.apple.com/api/v1/weather/en/41.4789363/-81.7404134?dataSets=forecastDaily&dailyStart=2025-03-21T04:56:00Z&timezone=America/New_York&countryCode=US Does anyone have any insights or information on this? Also if Apple is listening, an error more meaningful than 404 would be much much appreciated.

I have an app I want to get on the App Store but when I was putting in the build version slot, I accidentally deleted it by clicking backspace and tried everything to get it working again but I can't. Is there anyway for me to retrieve the slot so it works?

Hi Apple Developer, I’m working on a message-filtering application and reviewing Apple's documentation on message filtering. The documentation clearly states that MMS messages can be filtered. (https://developer.apple.com/documentation/identitylookup/sms-and-mms-message-filtering) When we refer to MMS, it includes images, short videos, and other supported multimedia formats. However, the ILMessageFilterQueryRequest only provides the message body as a String, meaning we can access text and links but not images or other media files. Could you please confirm whether Apple allows third-party applications to access multimedia content sent from unknown numbers? Looking forward to your quick response. Thanks, Rijul Singhal

As far as I know, Apple doesn’t allow apps to directly navigate users to the Call Blocking & Identification settings screen. That’s why many apps just show instructions like: "Go to Settings > Phone > Call Blocking & Identification" to enable the app. Apple only officially provides UIApplicationOpenSettingsURLString, which takes users to the app's own settings page. But here’s where I’m confused: some Korean apps like Whowho and Adot Phone seem to be able to direct users to the Call Blocking & Identification screen. Whowho: https://apps.apple.com/kr/app/whowho-spam-block-callerid/id1033450260?l=en-GB Adot Phone: I'm wondering how these apps are doing that. Are they using some kind of private API or workaround? Those app are developed from Internet Serivce Provider Company.
