App Clip Closes Before SKOverlay Can Show “Open” Button When Live Activity Is Involved
I have an App Clip that uses SKOverlay.AppClipConfiguration to install the full app. Before I added a Live Activity call (Activity.request), the user could see “Install,” then “Open.” Now, once “Get” is tapped, the Clip immediately closes—no “Open” button appears. If I remove the Live Activity code, it works again. I’ve confirmed that parent/child entitlements match, and tested via TestFlight. Is there a known issue or recommended workaround for combining SKOverlay + Live Activities in an App Clip so it doesn’t dismiss prematurely? Any insights are appreciated! Note live activity is for App Clip only.

How to remotely disable or block apps on a child’s device using FamilyControls and DeviceActivity API?
After reading Apple documentation (FamilyControls, DeviceActivity, ManagedSettings, ManagedSettingsUI, ScreenTime) and testing the API, I do not find a way to get the child's device apps on the parent device in order to block them or disable them for a certain time. Is there a way of doing it? Or can it only be done locally on the child device?

StoreKit2 Subscription Verification
My question is simple, I do not have much experience in writing swift code, I am only doing it to create a small executable that I can call from my python application which completes Subcription Management. I was hoping someone with more experience could point out my flaws along with giving me tips on how to verify that the check is working for my applicaiton. Any inight is appreciated, thank you. import Foundation import StoreKit class SubscriptionValidator { static func getReceiptURL() -> URL? { guard let appStoreReceiptURL = Bundle.main.appStoreReceiptURL else { print("No receipt found.") return nil } return appStoreReceiptURL } static func validateReceipt() -> Bool { guard let receiptURL = getReceiptURL(), let receiptData = try? Data(contentsOf: receiptURL) else { print("Could not read receipt.") return false } let receiptString = receiptData.base64EncodedString() let validationResult = sendReceiptToApple(receiptString: receiptString) return validationResult } static func sendReceiptToApple(receiptString: String) -> Bool { let isSandbox = Bundle.main.appStoreReceiptURL?.lastPathComponent == "sandboxReceipt" let urlString = isSandbox ? "https://sandbox.itunes.apple.com/verifyReceipt" : "https://buy.itunes.apple.com/verifyReceipt" let url = URL(string: urlString)! let requestData: [String: Any] = [ "receipt-data": receiptString, "password": "0b7f88907b77443997838c72be52f5fc" ] guard let requestBody = try? JSONSerialization.data(withJSONObject: requestData) else { print("Error creating request body.") return false } var request = URLRequest(url: url) request.httpMethod = "POST" request.httpBody = requestBody request.setValue("application/json", forHTTPHeaderField: "Content-Type") let semaphore = DispatchSemaphore(value: 0) var isValid = false let task = URLSession.shared.dataTask(with: request) { data, response, error in guard let data = data, error == nil, let jsonResponse = try? JSONSerialization.jsonObject(with: data) as? [String: Any], let status = jsonResponse["status"] as? Int else { print("Receipt validation failed.") semaphore.signal() return } if status == 0, let receipt = jsonResponse["receipt"] as? [String: Any], let inApp = receipt["in_app"] as? [[String: Any]] { for purchase in inApp { if let expiresDateMS = purchase["expires_date_ms"] as? String, let expiresDate = Double(expiresDateMS) { let expiryDate = Date(timeIntervalSince1970: expiresDate / 1000.0) if expiryDate > Date() { isValid = true } } } } semaphore.signal() } task.resume() semaphore.wait() return isValid } }

Traffic Events API
Hello developers! I am working with a team of North Carolina State University researchers to create an app or program that can retrieve real-time traffic events, such as hazards, road closures, and road construction alerts, in a similar manner to the Apple Maps app, but with the added functionality of collecting them over a historical period given a start and end date. I'm looking through the MapKit documentation, but there doesn't appear to be any functions exposing granular traffic data (i.e. road hazards), just travel times and level of congestion. Could anyone point me in the right direction? Is what I'm looking to do even possible using just Apple data?

Filtering MMS Messages with Multimedia Content (Images, Videos, etc.)
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

Gathering Required Information for Troubleshooting Tap to Pay on iPhone
While troubleshooting Tap to Pay on iPhone, it is essential that the developer is able to collect logs on their device and check those logs for error messages. This is also essential when reporting issues to Apple. To gather the required data for your own debugging as well as reporting issues, please perform the following steps on the test device: Install the Tap to Pay profile on your iPhone. Reproduce the issue and make a note of the timestamp when the issue occurred, while optionally capturing screenshots or video. Gather a sysdiagnose on the same iPhone. Create a Feedback Assistant report with the following information: The bundle ID The serial number of the device. For iOS, open Settings > General > About (tap and hold to copy). The SEID (Secure Element Identifier) of the device, represented as a HEX encoded string. For iOS, open Settings > General > About > SEID (tap and hold to copy). The sysdiagnose gathered after reproducing the issue. The timestamp (including timezone) of when the issue was reproduced. Screenshots or videos of errors and unexpected behaviors (optional). Submitting Your Feedback After your submission to Feedback Assistant is complete, please respond to your post with the Feedback ID. Once received, I can begin my investigation and determine if this issue is caused by an error within your app, a configuration issue within your developer account, app configuration, or an underlying system bug. Cheers, Paris X Pinkney |  WWDR | DTS Engineer

Universal Links are not working
I have an iOS app where the universal links are not working. Basically, I have double-checked the AASA file, and it's formatted correctly. It's in the right location .well-known subdirectory. I have checked other things as well. For my app, if the user has forgotten their password, they click on the Forgot Password option, which sends them an email, after which they click on a link; the link should open the iOS app, but is instead opening up the web browser. The format of the link matches the formatting in the AASA file. As well, I've checked associated domains as well. Using Postman, I can see that the AASA file is accessible. I have a feeling that the iOS app cannot fetch the AASA file, as I don't see any relevant swcd logs. My AASA file is located at: https://www.COMPANY_NAME.ca/.well-known/apple-app-site-association Please advise.

Issue with RCS Message Filtering on iOS 18.2.1 and 18.3
Hi Apple Developers, I am currently working on a message filtering application and facing issues specifically with filtering RCS (Rich Communication Services) messages. To debug this, I created a sample app that consistently categorizes all incoming messages as "junk." However, the filtering behaviour is inconsistent and not functioning as expected. Here are the key issues observed during testing on iOS versions 18.2.1 and 18.3: Inconsistent Filtering Behavior: When a message is received from an unknown number, it sometimes gets moved to the Junk folder momentarily but is then immediately moved back to the main Messages inbox. In some cases, the message does not get moved to the Junk folder at all, despite the app returning the verdict as "junk." Duplicate Contact Tiles: The Messages app displays two separate conversation tiles for the same mobile number, which is unexpected behavior. I have attached both a sample app and a screen recording that clearly demonstrates the issue. The recording shows that the app categorizes messages as junk, yet they still end up in the main Messages inbox. For reference, my carrier partner is T-Mobile. Please let me know if you need any additional information to investigate this issue further. Looking forward to your insights and guidance. Best regards, Rijul Singhal

Merchant validation error on Apple Pay payment processing
Hi, I'm developer in fintech company, we have setup process for onboarding merchants for our partner and processing payments with usage of Apple Pay API. Daily system is processing ca. 10k payments but every day ca. 100 of transactions are declined because of merchant validation error: request to https://apple-pay-gateway.apple.com/paymentservices/paymentSession (with all required parameters in body) is returning response with status code 417 "statusMessage": "Payment Services Exception merchantId={root merchant id} unauthorized to process transactions on behalf of merchantId={merchant id hash} reason={merchant id hash} is not a registered merchant in WWDR and isn't properly authorized via Mass Enablement, either." Issue impacts recurring merchants, most of their transactions are processed successfully but randomly some of them are failing with such reason. All prerequisites are met: merchant have deployed 'apple-developer-merchantid-domain-association' certificate, certificates are valid and not expired. Apple Support is not able to provide any information based on provided requests timestamps. We would to know what may be the reason just part of the requests are failing and what 417 error code means.

Request Array with AppIntent
Hi everyone, i'm trying to request in a AppIntent an array of strings. But I want to give the user the chance to add more than one String. Yet, I do it so: import AppIntent struct AddHomework: AppIntent { // some Parameters @Parameter(title: "Tasks") var tasks: [String]? @Parameter(title: "New Task") //Only for the special request var input: String? private func collectTasks() async throws -> [String] { var collectedTasks: [String] = tasks ?? [] while true { if !collectedTasks.isEmpty { let addMore = try await $input.requestConfirmation(for: "Möchtest du noch eine Aufgabe hinzufügen?") if !addMore { break } } let newTask = try await $input.requestValue("Please enter your task:") collectedTasks.append(newTask) } return collectedTasks } @MainActor func perform() async throws -> some IntentResult { let finalTasks = try await collectTasks() // some more code return .result() } } But this is not working. The Shortcut is ending without requesting anything. But it is not crashing. I would thankfully for some help.

CMAltimeter becomes somehow uncalibrated: absolute locations not delivered anymore (temporarily)
Note: I have had issues with CMAltimeter since whats seems to have been a major undocumented modification since iOS 17.4. So I'm using the CMAltimeter absolute locations delivery. Sometimes, the altimeter seems to be in an uncalibrated mode and therefore, no altitude delivery happens. Is there a way to be inform of such state? Currently, it just doesn't work and I can't inform the user about this. They just think the app is broken What message should I give to the users to accelerate the calibration such that the CMAltimeter will work again? Also, users have reported that the CMAltimeter can temporarily stop delivering altitude updates, even though it should. So I guess my question resumes to this: Whats the best practice to handle an uncalibrated CMAltimeter? Thanks!

AppleScript help
Hello everyone, I would like to use AppleScript to transform a .csv file. To make things easier to understand, I'm attaching two files: 1- The original file in csv format 2- The file as I'd like it to look after I've run it through the script. Here are the steps involved 1-Open the file in numbers (Note: the file is located in the download folder). 2-Delete the first 6 lines 3-Delete all font styles and cell colors 4-Combine all cells in the nature of operation column of the same operation belonging to the same date in the first cell of the operation, deleting all spaces in the text is not necessary for each operation. 5- Delete all empty lines. I hope I've made my request clear. If any of you have the knowledge to do this, if it can be done at all, I'd be very grateful for their help in writing the script. Thank you in advance. 1.csv 2.csv

Possible to allow x code builds to run background processes for over 3 minutes
I have an app that I'm using for my own purposes and is not in the app store. I would like to run an http server in the background for more than the allotted 3 minutes to allow persistent communications with a connected Bluetooth device. The Bluetooth device would poll the service at intervals. Is this possible to do? This app does not need app store approval since it's only for personal use.

SwiftData propertiesToFetch question
I have a simple model @Model final class Movie: Identifiable { #Index\<Movie\>(\[.name\]) var id = UUID() var name: String var genre: String? init(name: String, genre: String?) { self.name = name self.genre = genre } } I turned on SQL debugging by including '-com.apple.CoreData.SQLDebug 3' argument on launch. When I fetch the data using the following code, it selects 3 records initially, but then also selects each record individually even though I am not referencing any other attributes. var fetchDescriptor = FetchDescriptor\<Movie\>() fetchDescriptor.propertiesToFetch = \[.id, .name\] fetchDescriptor.fetchLimit = 3 do { print("SELECT START") movies = try modelContext.fetch(fetchDescriptor) print("SELECT END") } catch { print("Failed to load Movie model.") } I see it selecting the 3 rows initially, but then it selects each one separately. Why would it do this on the initial fetch? I was hoping to select the data that I want to display and let the system select the entire record only when I access a variable that I did not initially fetch. CoreData: annotation: fetch using NSSQLiteStatement <0x600002158af0> on entity 'Movie' with sql text 'SELECT 1, t0.Z_PK, t0.ZID, t0.ZNAME FROM ZMOVIE t0 LIMIT 3' returned 3 rows with values: ( "<NSManagedObject: 0x600002158d70> (entity: Movie; id: 0xa583c7ed484691c1 <x-coredata://71E60F4C-1A40-4DB7-8CD1-CD76B4C11949/Movie/p1>; data: <fault>)", "<NSManagedObject: 0x600002158d20> (entity: Movie; id: 0xa583c7ed482691c1 <x-coredata://71E60F4C-1A40-4DB7-8CD1-CD76B4C11949/Movie/p2>; data: <fault>)", "<NSManagedObject: 0x600002158f00> (entity: Movie; id: 0xa583c7ed480691c1 <x-coredata://71E60F4C-1A40-4DB7-8CD1-CD76B4C11949/Movie/p3>; data: <fault>)" ) CoreData: annotation: fetch using NSSQLiteStatement <0x600002154d70> on entity 'Movie' with sql text 'SELECT 0, t0.Z_PK, t0.Z_OPT, t0.ZGENRE, t0.ZID, t0.ZNAME FROM ZMOVIE t0 WHERE t0.Z_PK = ? ' returned 1 rows CoreData: annotation: with values: ( "<NSSQLRow: 0x600000c89500>{Movie 1-1-1 genre=\"Horror\" id=4C5CB4EB-95D7-4DC8-B839-D4F2D2E96ED0 name=\"A000036\" and to-manys=0x0}" ) This all happens between the SELECT START and SELECT END print statements. Why is it fulfilling the faults immediately?

Combine delay & switchToLatest publisher don't emit value sometimes
Hello, I recently implemented a conditional debounce publisher using Swift's Combine. If a string with a length less than 2 is passed, the event is sent downstream immediately without delay. If a string with a length of 2 or more is passed, the event is emitted downstream with a 0.2-second delay. While writing test logic related to this, I noticed a strange phenomenon: sometimes the publisher, which should emit events with a 0.2-second delay, does not emit an event. The test code below should have all indices from 1 to 100 in the array, but sometimes some indices are missing, causing the assertion to fail. Even after observing completion, cancel, and output events through handleEvents, I couldn't find any cause. Am I using Combine incorrectly, or is there a bug in Combine? I would appreciate it if you could let me know. import Foundation import Combine var cancellables: Set<AnyCancellable> = [] @MainActor func text(index: Int, completion: @escaping () -> Void) { let subject = PassthroughSubject<String, Never>() let textToSent = "textToSent" subject .map { text in if text.count >= 2 { return Just<String>(text) .delay(for: .seconds(0.2), scheduler: RunLoop.main) .eraseToAnyPublisher() } else { return Just<String>(text) .eraseToAnyPublisher() } } .switchToLatest() .sink { if $0.count >= 2 { completion() } }.store(in: &cancellables) for i in 0..<textToSent.count { let stringIndex = textToSent.index(textToSent.startIndex, offsetBy: i) let stringToSent = String(textToSent[textToSent.startIndex...stringIndex]) subject.send(stringToSent) } } var array = [Int]() for i in 1...100 { text(index: i) { array.append(i) } } DispatchQueue.main.asyncAfter(deadline: .now() + 5) { for i in 1...100 { assert(array.contains(i)) } } RunLoop.main.run(until: .now + 10)

Accessory Setup Kit - Set WIFI SSID to ASAccessory after initial setup
I have an accessory which uses both Bluetooth and WiFi to communicate with the app. I am trying to migrate to Accessory Setup Kit. However, the API expects both the bluetooth identifiers and WIFI SSID or SSID prefix in the ASDiscoveryDescriptor. The problem is we only have the WIFI SSID after BLE pairing. Our current flow looks like this: Pair via BLE Connect via BLE Send a BLE command to request WIFI settings (SSID and password) (Each device has a different SSID and password) Connect to WI-FI hotspot by calling NEHotspotConfigurationManager applyConfiguration with the retrieved credentials. Is there a way to set the Wi-Fi SSID of an ASAccessory object after the initial setup? To use Accessory Setup Kit we would need something like this: Call Accessory Setup Kit with bluetooth identifiers in the descriptor, finish the setup and get ASAccessory object. Connect via BLE Send a BLE command to request WIFI settings (SSID and password) Set the SSID of the ASAccessory to the retrieved value. Connect to WI-FI hotspot by calling `NEHotspotConfigurationManager joinAccessoryHotspot. Thanks!
