In my Catalyst app I use func setupMailComposer() { // Check if the device can send email guard MFMailComposeViewController.canSendMail() else { print("Mail services are not available") showMailErrorAlert() return } // Create and configure the mail composer let mailComposeVC = MFMailComposeViewController() mailComposeVC.mailComposeDelegate = self // Set the email details mailComposeVC.setToRecipients(["example@example.com"]) mailComposeVC.setSubject("Subject for your email") mailComposeVC.setMessageBody("This is the body of the email.", isHTML: false) // Attach a file (optional) if let filePath = Bundle.main.path(forResource: "example", ofType: "pdf"), let fileData = try? Data(contentsOf: URL(fileURLWithPath: filePath)) { mailComposeVC.addAttachmentData(fileData, mimeType: "application/pdf", fileName: "example.pdf") } // Present the mail composer self.present(mailComposeVC, animated: true, completion: nil) } Since I have updated to macOS 15.1 the canSendMail() function returns false although I have configured Apple Mail (like before in 15.0 where it worked flawlessly).

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.

Hello! We're currently testing Live Caller ID implementation and noticed an issue with userIdentifier values in our database. Initially, we expected to have approximately 100 records (one per user), but the database grew to about 10,000 evaluationKey entries. Upon investigation, we discovered that the userIdentifier (extracted from "User-Identifier" header) for the same device remains constant throughout a day but changes after a few days. We store these evaluation keys using a composite key pattern "userIdentifier/configHash". All these entries have the same configHash but different userIdentifier values. This behavior leads to unnecessary database growth as new entries are created for the same users with different userIdentifier values. Could you please clarify: Is this the expected behavior for userIdentifier to change over time? If yes, is there a specific TTL (time-to-live) for userIdentifier? If this is not intended, could this be a potential iOS bug? This information would help us optimize our database storage and implement proper cleanup procedures. Thank you for your assistance!

i thought it is impossible to have CallKit show system UI for outgoing calls. but then i saw this: "For incoming and outgoing calls, CallKit displays the same interfaces as the Phone app..." https://developer.apple.com/documentation/callkit how do i present it though? or is this a documentation error?

Hi everyone, We’re experiencing a persistent issue with an App Clip Experience that continues to load on iOS devices even after being deactivated in App Store Connect more than 48 hours ago. Issue Summary An App Clip Experience tied to the URL pattern https://srgplus.com/u/... keeps appearing when scanning NFC tags or QR codes, despite being removed from App Store Connect. Key Details The App Clip Experience was deactivated over 48 hours ago. iOS still launches the App Clip when scanning NFC tags or QR codes that match the URL structure. The specific token-based App Clip Experience (for example: https://srgplus.com/u/iohgqa) was removed, but iOS still loads an App Clip as if the Experience exists. It seems like iOS is falling back to a previously registered base URL Pattern such as: https://srgplus.com/u or possibly even https://srgplus.com The problem: This fallback App Clip is not visible anywhere in App Store Connect → Advanced App Clip Experiences. So we cannot delete or modify it. The behavior persists across: Multiple devices Different networks After clearing device caches After reinstalling our app Even after scanning using devices that never used this App Clip before This makes us believe that the App Clip Experience may be: Cached on Apple’s servers Or orphaned/hidden in App Store Connect Or not properly removed from the URL pattern registry Steps to Reproduce Deactivate an App Clip Experience in App Store Connect. Wait 48 hours or more. Scan an NFC tag or QR code pointing to a previously used URL pattern. App Clip still appears, even though no active Experience exists. Expected Behavior App Clip should stop appearing once the Experience is deactivated and removed. Actual Behavior App Clip continues to load indefinitely, suggesting a cached or orphaned configuration. Question Has anyone encountered similar behavior? Is there a way to request a manual purge of App Clip URL patterns or cached Experiences from Apple’s side? Any guidance or insights would be greatly appreciated. Thank you!

Is there any resource which describes this type of errors? I was integrating SKADNetwork view through Ad attribution and everything from the source app side is done and this error appears after the target app is installed and opened. Here is the full error Error setting install attribution pingback registered for app: <APP ID>, error: Error Domain=ASDErrorDomain Code=1209 "SKAdNetwork: Could not set registered for pingback that does not exist." UserInfo={NSLocalizedDescription=SKAdNetwork: Could not set registered for pingback that does not exist.}, result: 0 I cannot find any resource on the internet which gives any info about this ASDErrors. If anyone can help, you would be doing me a solid, Thanks in advance.

Hey there, I have a slight problem which is also known on the web, but I couldn't find any answers... My iOS App is working with documents like pdf and images. It is made to handle invoices and upload them to an external service. The app's job is to compress those pdfs and images. Sadly the PDFKit's PDFDocument increases its size just after importing it with pdfDocument = PDFDocument(url: url) and later exporting it to an pdf file again with data = pdf.dataRepresentation() without ever modifying it. It increases by server KB after each export. Do you have any alternatives to the renderer dataRepresentation() or a general PDFKit alternative Thanks

Hi everyone, I’ve been stuck on an issue with iOS Universal Links for about a week and could really use some help. The problem When tapping a Universal Link on iOS, my Flutter app opens correctly (desired behavior) — but immediately afterward, Safari opens the same link in the browser. So both the app and the browser open. This only happens on iOS. On Android everything works as expected. What works If the link is simply the domain, like: https://mydomain.com …then the app opens without triggering the browser afterward. This is the correct behavior. What doesn’t work If the link includes a path or parameters, like: https://mydomain.com/path https://mydomain.com/path?param=value …then the app opens, and then the browser opens immediately after. What I’ve tried Verified my AASA file using Branch’s validator: https://branch.io/resources/aasa-validator/ → The AASA file is valid. Universal Links do open the correct screen inside the app — the issue is the unwanted second step (Safari opening). Behavior is consistent across different iOS devices. Extra details Using Flutter. Universal Links set up with the standard configuration (associatedDomains, AASA hosted at /.well-known/apple-app-site-association, etc.). Question Has anyone encountered this issue where Universal Links with paths/params open the app and then open Safari? What could cause iOS to trigger the browser fallback even when the AASA file is valid and the app handles the link correctly? Any insights, debugging tips, or known edge cases would be incredibly appreciated!

In the summary documentation about the declared Age Range API:https://developer.apple.com/news/?id=2ezb6jhj It states: "The API will also return a signal from the user’s device about the method of age assurance, such as credit card or government ID" But if the api itself, and its documentation is examined, there is no such mechanism nor mention of it: https://developer.apple.com/documentation/declaredagerange/agerangeservice So my question is, is the first documentation incorrect, if not, then where and how to access the method of age assurance?

I use WeatherKit with Swift to get multiple cities weather by longitude and latitude. But I use this API in WeatherService for daily forecast: final public func weather<T>(for location: CLLocation, including dataSet: WeatherQuery<T>) async throws -> T And I found there is something wired: The date of WeatherKit::DayWeather is based on my device's timezone settings. Tokyo's Day Weather is start at UTC+8, New York' Day Weather is start UTC+8. Is there any way to set timezone correctly?

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!

I have an app developed by using the Callkit/Call-Blocking and received feedback from individual users, when using [cxcalldirectorymanager reloadextensionwithidentifier] to write call blocking data, it returned error code 11 with the following contents: errorCode: 11 errorDomain: com.apple.callkit.database.sqlite errorDescription: sqlite3_step for query 'DELETE FROM PhoneNumberBlockingEntry WHERE extension_id =?' returned 11 (11) errorMessage 'database disk image is malformed' I want to know the reasons for this error and how to solve it，Thanks!

Hi We have an AppleTV app that is used to continuously display information (digital signage). One of our clients reports that their AppleTV returns to the homescreen by morning. While our recommendation is to setup Mobile Device Management to lock the AppleTV into running only our app, not every client will have the IT knowledge to set this up. So we're trying to figure out possible causes for the app getting closed. We've not received any crash reports, nor does the device give any indication the app crashed. The energy saving settings are set to run continuously without sleep. The client is reporting this happens every night, so it seems unlikely to be caused by tvOS updates. Are there other things I could rule out to find the cause of this issue? Any ideas are welcome, thanks!

The value of ProcessInfo.processInfo.operatingSystemVersion on iOS 26 is returning 19.0.0 would of expected 26.0.0

The API we used: NSURL *url = [NSURL URLWithString:@"App-Prefs:INTERNET_TETHERING"]; The link provided by Apple engineer: https://developer.apple.com/forums/thread/761314 I did not find any URL in the link that leads to the secondary menu of system settings. Does this suggest that iOS 26 does not support this functionality? Moreover, is it possible that versions of iOS 18 and earlier may also not support this behavior in the future?

IMPORTANT Rather than use the code below, I recommend that you adopt Swift’s shiny-new Subprocess package. That’s what I’m doing! (-: Running a child process using Process (or NSTask in Objective-C) is easy, but piping data to and from the child’s stdin and stdout is surprisingly tricky. I regularly see folks confused by this. Moreover, it’s easy to come up with a solution that works most of the time, but suffers from weird problems that only show up in the field [1]. I recently had a couple of DTS incidents from folks struggling with this, so I sat down and worked through the details. Pasted below is the results of that effort, namely, a single function that will start a child process, pass it some data on stdin, read the data from the child’s stdout, and call a completion handler when everything is done. There are some things to note here, some obvious, some not so much: I’ve included Swift and Objective-C versions of the code. Both versions work the same way. The Swift version has all the comments. If you decide to base your code on the Objective-C version, copy the comments from there. I didn’t bother collecting stderr. That’s not necessary in many cases and, if you need it, it’s not hard to extend the code to handle that case. I use Dispatch I/O rather than FileHandle to manage the I/O channels. Dispatch I/O is well suited to this task. In contrast, FileHandle has numerous problems working with pipes. For the details, see Whither FileHandle?. This single function is way longer than I’d normally tolerate. This is partly due to the extensive comments and party due to my desire to maintain focus. When wrapping Process it’s very easy to run afoul of architecture astronaut-ism. Indeed, I have a much more full-featured Process wrapper sitting on my hard disk, but that’s going to stay there in favour of this approach (-: Handling a child process correctly involves some gnarly race conditions. The code has extensive comments explaining how I deal with those. If you have any questions or comments about this, put them in a new thread. Make sure to tag that thread with Foundation and Inter-process communication so that I see it.

When I call https://developer.apple.com/documentation/contactprovider/contactprovidermanager/enable() to request to use Contact Provider, I received a dialog with message like this "App Name would like to add its contacts as its own list. Contacts added this way can be removed from settings". I would like to support this message in Japanese or other languages. Is it possible?
