iOS 26 Empty Stack Crash
When we compile our app using Xcode 26 and run it on iOS 26, we encounter a strange crash where the crashing thread shows no stack trace. After inspecting the registers, we have initially traced it to the Google Mobile Ads SDK. When we disable the initialization of the Google Mobile Ads SDK, the app no longer crashes. However, running the Google Mobile Ads SDK demo app on iOS 26 alone does not cause any issues; the crash only occurs once it is integrated into our app. We also tried enabling Address Sanitizer and Zombie Objects but found no valuable clues. Could you advise what other methods or tools we can use to further diagnose this issue? Additionally, when we compile the app with Xcode 15 and run it on iOS 26, everything works fine without crashes. app-2025-09-19-161044.ips.txt

How is Security Delay still so broken?
I'm sitting at my house and trying to sign my test device out of my apple ID so I can sign into a Sandbox user, but now I have an hour to kill because of this terribly broken "security" feature that thinks it's in an unfamiliar location, despite being at the only location it's ever known. Looks like I'll just be disabling this feature all together. Especially as a device with Developer Mode enabled, which gets reset regularly, there should be additional options here. Come on!

Use VZVirtualMachineView with actor-isolated VZVirtualMachine
We are using VZVirtualMachine instances in a Swift actor. It works fine but we hit a major problem when we decided that we want to attach it to a VZVirtualMachineView to show it / allow user interactions. VZVirtualMachineView and its virtualMachine property is isolated to @MainActor, so if we directly assign our vm instance to it, we receive a concurrency error: @MainActor public func createView() -> VZVirtualMachineView { let view = VZVirtualMachineView() view.virtualMachine = vm // x: Actor-isolated property 'vm' can not be referenced from the main actor return view } Is there any way we can make this work?

CallKit answer screen video button
Hello, currently working on messenger with audio/video calls feature. Have found strange behavior, on some devices after accepting call via Lock Screen video button appears to be disabled. Tested on wwdc Speakerbox sample, same code iPhone 15 Pro (iOS 17.4.1) - video button disabled iPhone 14 (iOS 17.6.1) - video button active Here is my, configuration with supportVideo activated static let providerConfiguration: CXProviderConfiguration = { let configuration = CXProviderConfiguration() configuration.supportsVideo = true configuration.maximumCallGroups = 1 configuration.maximumCallsPerCallGroup = 1 configuration.supportedHandleTypes = [.generic] return configuration }() What can be the reason of this behavior? Thanks

Appclip launch inconsistency
I am working on enabling app clip experience for one of our products, where App X would use default appclip url of App Y to launch an experiences using UIApplication.shared.open(defaultAppclipUrl). Im successfully able to build and submit to appstore by testing via local expereince, but later noticed a strange behaviour in production without local expereince setup, where tapping a button in App X (with default appclip url) fails to launch the appclip for the first time but loads fine from the second try. I learned that in background Apple would make a API call to fetch details about app clip availability in store and then proceed to launch app clip locally, hence the delay->timeout->failure for first tap. Once the invocation starts working it would be consistent. After couple of minutes of break say 20m, it again fails for 1st time. I'm assuming that iOS is invalidating the cache on device regarding availability of appclip in store and hence the API call is made again and there is a delay and failure. can you please help us with this issue.

Can not replicate the Apple Review error
Hello there! So Im trying to upload an app to the App Store for iphone and Ipad, but from the revision team the same message always appears, the app crash. So I know the "it works on my computer" sounds bad but....works on my computer and my test system. Dont know what to do since I dont know how to replicate the error. This is the rely they sent me: Issue Description The app exhibited one or more bugs that would negatively impact users. Bug description: at time of review the app’s interface went blank at launch. Review device details: Device type: iPad Air (5th generation) OS version: iPadOS 18.4.1 Anyone has any idea on how can I replicate the error and maybe check the logs? Im completely blind on this one.

Call Directory Number Matching Inconsistency Across Regions
[Question] Inconsistent Call Directory number matching across regions (Japan, Taiwan, U.S.) We’re developing a Call Directory extension and observed inconsistent number matching depending on carrier region and number format. Environment Device: iPhone (iOS 26.0) Call Directory Extension: Custom implementation Carrier A: Japan carrier SIM Carrier B: Taiwan carrier SIM Numbers added to Call Directory patterns: +81 120 580 2XXX +81 704 336 2XXX Observed Behavior (Japan Carrier SIM) Incoming call from +81 120 580 2XXX → Caller name not displayed (Call Directory match failed). Entering 0120 580 2XXX in the Phone app dialer → Name displayed correctly. Incoming call from +81 704 336 2XXX → Caller name displayed correctly. Entering 070 4336 2XXX in the Phone app dialer → Name displayed correctly. Observed Behavior (Taiwan Carrier SIM) Entering +81 120 580 2XXX in the dialer → Name not displayed until the call button is pressed. Entering +81 704 336 2XXX in the dialer → Name displayed immediately, before the call is placed. Steps to Reproduce For Japan carrier: Use a device running iOS 26 with a Japanese SIM card. Add the following numbers to the Call Directory extension: +81 120 580 2XXX and +81 704 336 2XXX Receive an incoming call from +81 120 580 2XXX → ❌ Caller name not displayed. Open the Phone app and enter 0120 580 2XXX → ✅ Caller name displayed. Receive an incoming call from +81 704 336 2XXX → ✅ Caller name displayed. Open the Phone app and enter 070 4336 2XXX → ✅ Caller name displayed. For Taiwan carrier: 7. Insert a Taiwan SIM card (keep the same Call Directory patterns). 8. Enter +81 120 580 2XXX → ❌ Name not shown until the call button is pressed. 9. Enter +81 704 336 2XXX → ✅ Name shown immediately. Expected Result For both numbers: Caller name from Call Directory should display consistently: a) On incoming calls. b) When entering the full number in the dialer (before pressing call). Behavior should be consistent across regions (Japan, Taiwan, United States). Actual Result Region / Carrier Number Pattern Incoming Call Dialer (Local Format) Japan +81 120 580 2XXX ❌ Not shown ✅ Shown (0120 580 2XXX) Japan +81 704 336 2XXX ✅ Shown ✅ Shown (070 4336 2XXX) Taiwan +81 120 580 2XXX N/A ❌ Not shown until call Taiwan +81 704 336 2XXX N/A ✅ Shown immediately Questions How should numbers be formatted or stored in the Call Directory patterns so that they match both incoming calls and dialer input consistently across regions? Are there region-specific number normalization rules (e.g., Japan’s 0-prefixed local dialing or Taiwan’s international format handling)? Is there an official guideline or recommendation for formatting phone numbers in Call Directory extensions (e.g., E.164 vs local format) to ensure consistent matching? Notes The inconsistent behavior appears to be related to how iOS normalizes numbers per carrier region and local dialing conventions. In Japan, incoming calls from mobile numbers starting with 070 match correctly, while 0120 (toll-free) fails unless entered in local format.

Creating ApplicationToken with Decoder from string
I've been working a lot with the FamilyControls API and App Shield recently but have encountered a problem with no documentation. I used the FamilyActivitySelection to select the app store to shield(This is just for testing), and then printed out the application token: 1wfY¸êB ò S« öi #×(É?âðw ù/jQ ¿ J ïE¢? ·¿ º<Òd?ý r7¥Ãn N átJ¹ÿ85B_{VAF fC8. ,,¸¯3 T7F ±õü; ¹?v@¯ô Ä \-õ# Ò I know the application token is a Codable object so I was wondering, How do I create an application token using the Token<Application> initializer init(from: any Decoder) throws Creates a new instance by decoding from the given decoder. Using the above data? Do I have to encode first in order to decode it? For reference, the code I tried to use is: newValue.applicationTokens.encode(to: JSONEncoder) if let encoded = try? JSONEncoder().encode(newValue.applicationTokens) { data = encoded print(String(data: data, encoding: .utf8)!) } if let app = try? JSONDecoder().decode(Token<Application>.self, from: data) { let token = Application(token: app) print(token) } else { print("didn't work") } But it prints didn't work every time. What should I do differently?

Core Spotlight searching only for title
I just adding a way to donate my app's data to Core Spotlight using CSSearchableIndex, but I'm finding that spotlight is only searching for the title of the CSSearchableItem I create. I know the index is working, because it always finds the item through the title property, but nothing else. This is how I'm creating the CSSearchableItem: - (CSSearchableItem *) createSearchableItem { CSSearchableItemAttributeSet* attributeSet = [[CSSearchableItemAttributeSet alloc] initWithContentType: UTTypeText]; attributeSet.title = [self titleForIndex]; attributeSet.displayName = [self titleForIndex]; attributeSet.contentDescription = [self contentDescriptionForIndex]; attributeSet.thumbnailData = [self thumbnailDataForIndex]; attributeSet.textContent = [self contentDescriptionForIndex]; CSSearchableItem *item = [[CSSearchableItem alloc] initWithUniqueIdentifier: [self referenceURLString] domainIdentifier:@"com.cjournal.cjournal-Logs" attributeSet:attributeSet]; item.expirationDate = [NSDate distantFuture]; return item; } There's a lot of confusing tips around which say specifying the 'textContent' should work, and/or setting the displayName is essential, but none of these are working. Is there something I'm missing with my setup? Thanks.

Automatic App Icon Style Change in iOS 26
After updating from iOS 18 to iOS 26, our app icon appears to have automatically received the new 'Liquid Glass' effect. We confirmed that this change occurred without us releasing a new app update. My questions are: Is this a system behavior where iOS 26 automatically applies the new icon style to existing apps? If so, is it possible for a developer to control or customize this effect? I am also wondering if there are any methods other than using Icon Composer.

FinanceKit - Any way to get merchant location info from transactions?
Hi all — I’m building a Wallet-style transaction details view using FinanceKit and I’m running into a gap around merchant location. What I’m seeing FinanceKit gives me great core fields (amount, currency, status, dates, MCC, merchantName, transactionDescription), but I’m not seeing any address or place/location metadata on a Transaction. For example, a small/local merchant where I can plausibly infer a single place: Fetched transaction: Transaction( id: 8D142B16-3E0E-40B8-945A-2E7C0CF65F1D, accountID: 14939CF4-DBC3-4A9D-8292-5FEA495B8461, transactionAmount: 47.24 USD, creditDebitIndicator: .debit, transactionDescription: "Local Dental Care", originalTransactionDescription: "Local Dental Care", merchantCategoryCode: 8021, merchantName: "Local Dental Care", transactionType: .pointOfSale, status: .booked, transactionDate: 2025-08-20 22:27:50 +0000, postedDate: 2025-08-21 11:22:06 +0000 ) Because this appears to be a single-location practice, I can usually resolve it to a place using MapKit search heuristics. But for big-box chains, I don’t get enough signal to determine which store: Fetched transaction: Transaction( id: 3F8E9F74-7565-4D24-9038-8FD709184799, accountID: 14939CF4-DBC3-4A9D-8292-5FEA495B8461, transactionAmount: 441.77 USD, creditDebitIndicator: .debit, transactionDescription: "The Home Depot", originalTransactionDescription: "The Home Depot", merchantCategoryCode: 5200, merchantName: "The Home Depot", transactionType: .pointOfSale, status: .booked, transactionDate: 2023-12-27 23:07:02 +0000, postedDate: 2023-12-29 03:09:41 +0000 ) There’s no store number, address, phone, or any stable identifier. With hundreds of locations, I can’t deterministically choose a map pin or fetch the right brand assets. What I’m trying to achieve I’d like to replicate the Apple Wallet experience: show a small map snapshot and merchant visuals (logo/name that match Apple Maps / the Place Card) on the transaction detail screen. Without a location hint, I have to either: Ask users to pick a store manually, or Make a guess based on a coarse, app-defined region …neither of which feels great. Questions Is there any way in FinanceKit today to access merchant location or a resolvable identifier (e.g., address, city/state, store number, Apple Maps place identifier, network merchant ID/MID, terminal ID, etc.)? If not, can FinanceKit expose additional merchant metadata (even opt-in / privacy-preserving) to enable Wallet-like enrichment? A few examples that would unblock this: merchantAddress (or components: street/city/region/postalCode/country) merchantPhone (often unique per store) merchantIdentifier (stable per physical location, e.g., network merchant ID / store number) mapsPlaceURL or mapsPlaceIdentifier (linkage to the Apple Maps Place Card) brandAssetURL (logo/brand reference similar to what Wallet shows) With even one of the above, I could reliably: Render an accurate map snapshot, Fetch the correct brand assets, and Avoid prompting the user or inferring via fuzzy search. Context / constraints I do not want to (and shouldn’t need to) request or monitor the user’s device location to resolve a merchant’s store location. For small merchants, MapKit text search is often enough. For large chains, I need a store-level identifier. If there’s an existing field or recommended approach I’m missing, I’d love pointers. If not, please consider this a feature request for richer merchant metadata in FinanceKit so developers can build Wallet-quality transaction details. Thanks!

How to get the bundleIdentifier or app name from FamilyActivitySelection's applicationTokens?
I'm working with the FamilyControls and DeviceActivity frameworks in iOS (Swift). In my app, I collect selected apps using a FamilyActivitySelection, and I access the selected apps via selection.applicationTokens, which gives me a Set. I would like to get either the bundle identifier or the display name of the selected apps from these ApplicationTokens. I tried creating an Application instance using: let app = Application(token: token) print(app.bundleIdentifier) print(app.localizedDisplayName) However, both bundleIdentifier and localizedDisplayName are always nil. My questions are: Outside the extension (in the main app), how can I get the bundleIdentifier or display name from an ApplicationToken? Is there an Apple-recommended way to resolve a Token into something human-readable or usable? If not, what is the best practice to store or identify user-selected apps for later use? Environment: iOS 17, Swift 5, Using FamilyControls and DeviceActivity APIs. Thank you for any help!

Live Caller ID Lookup - Error on Refresh PIR Parameters
Hello. I've implemented the Live Caller ID Lookup feature in my app, but sometimes I get a weird error. When I call LiveCallerIDLookupManager.shared.refreshPIRParameters(...) from my app, it sometimes throws an error: Error Domain=com.apple.CipherML Code=1100 "Unable to query status due to errors: The resource could not be loaded because the App Transport Security policy requires the use of a secure connection." UserInfo={NSLocalizedDescription=Unable to query status due to errors: The resource could not be loaded because the App Transport Security policy requires the use of a secure connection., NSUnderlyingError=0x118f65740 {Error Domain=NSURLErrorDomain Code=-1022 "The resource could not be loaded because the App Transport Security policy requires the use of a secure connection." UserInfo={NSLocalizedDescription=The resource could not be loaded because the App Transport Security policy requires the use of a secure connection., NSErrorFailingURLKey=http://www.example.com/config}}} What does this error mean? And where did the example.com part come from? What should I do to get rid of this error? My Service URL is hardcoded in the Live Caller ID Lookup Extension of my app and it is definitely not example.com.

ContactAccessButton presents invisible sheet
On a device with approx 800 contacts, the sheet presented when tapping ContactAccessButton with multiple matches briefly appears (.25 seconds) before disappearing, leaving the view below in a dimmed, slightly zoomed out, non-interactive state as if a sheet were being presented. Swiping down dismisses the invisible sheet returns the underlying view to a normal state. Is there a way to avoid this? It appears possibly similar to https://developer.apple.com/forums/thread/762077 Logs (exact duplicates removed) #ContactsButton response after touch -- Should show UI LaunchServices: store (null) or url (null) was nil: Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=72, _LSFunction=_LSServer_GetServerStoreForConnectionWithCompletionHandler} Attempt to map database failed: permission was denied.
