Sync Conflict Between Contacts & Maps, Possible Cross-App Link with Home App Issue
Pinned 2 homes address for the same contact Steps Initial check in Apple Maps No saved places or pinned addresses appear. Open Personal Contacts You have two addresses stored in your contact card: Main and Home. Pin & Edit “Main” You pinned the Main address in Maps. Refined the location on the map. Renamed it (but still saved under the type “My Home”). Open “Home” Address in Contacts Refined the location again. Changed the type to “My Home.” Attempted to rename, but no option to change the label. Final Saved Places View Shows two entries both called “Main.” Opening either of them displays the same details for the Home address. Saved Places list only shows the full address text, without the ability to rename them inside Maps. Results Both addresses appear duplicated with the same name (“Main”), even though they point to different underlying addresses. When selecting either entry, Apple Maps incorrectly shows the same Home address details. The Saved Places section does not allow renaming; it defaults to showing the full address string. Issues Identified Sync Conflict Between Contacts & Maps Apple Maps pulls labels/types from Contacts, but the edits don’t update consistently across apps. Duplicate Naming Bug Both “Main” and “Home” collapse into “Main” in Saved Places, making them indistinguishable. One-to-One Mapping Failure Regardless of which saved place you open, Maps shows the same Home entry, meaning the system isn’t correctly binding each saved place to its respective contact address. Renaming Limitation Apple Maps doesn’t allow renaming saved addresses directly — it relies on Contacts. Since Contacts only supports preset labels (Home, Work, School, etc.), custom naming is blocked.

CLMonitor init function causes app crash
I'm experiencing app crashes when calling the CLMonitor initialization function: let monitor = await CLMonitor("my_monitor") According to WWDC 2023: Meet Core Location Monitor, when creating a CLMonitor object with the same identifier, it should access the existing monitor without any mention of app crashes or buggy behavior. However, in my actual testing, attempting to create a CLMonitor object with the same identifier immediately causes an app crash. Here's part of the crash log: Last Exception Backtrace: 0 CoreFoundation 0x19c4ab21c __exceptionPreprocess + 164 (NSException.m:249) 1 libobjc.A.dylib 0x199945abc objc_exception_throw + 88 (objc-exception.mm:356) 2 Foundation 0x19b7a9670 -[NSAssertionHandler handleFailureInMethod:object:file:lineNumber:description:] + 288 (NSException.m:252) 3 CoreLocation 0x1aa25cbb4 +[CLMonitor _requestMonitorWithConfiguration:locationManager:completion:] + 516 (CLMonitor.mm:516) 4 libswiftCoreLocation.dylib 0x22bf6085c CLMonitor.init(_:) + 488 (CLMonitor.swift:280) 5 libswiftCoreLocation.dylib 0x22bf604b9 <deduplicated_symbol> + 1 6 MiniPlengi 0x106372ec9 closure #1 in static CLMonitor.loplatMonitor.getter + 1 (CLMonitor+Extensions.swift:31) 7 MiniPlengi 0x1062ce325 0x106290000 + 254757 8 MiniPlengi 0x1062f6a29 specialized thunk for @escaping @isolated(any) @callee_guaranteed @async () -> (@out A) + 1 (/<compiler-generated>:0) 9 MiniPlengi 0x1062ce325 0x106290000 + 254757 10 libswift_Concurrency.dylib 0x1a7f75241 completeTaskWithClosure(swift::AsyncContext*, swift::SwiftError*) + 1 (Task.cpp:537) Furthermore, even though I've written code to create CLMonitor objects based on a singleton structure to handle these crash cases, the app still crashes: extension CLMonitor { static var loplatMonitor: CLMonitor { get async { struct Static { static var monitor: CLMonitor? static var initializationTask: Task<CLMonitor, Never>? } // If already initialized if let monitor = Static.monitor { return monitor } // If there's an initialization task in progress, wait for its result if let task = Static.initializationTask { return await task.value } // Create new initialization task let task = Task { let monitor = await CLMonitor("my_monitor") Static.monitor = monitor Static.initializationTask = nil // Clean up task after completion return monitor } Static.initializationTask = task return await task.value } } } Is the CLMonitor API still in a stabilization phase and not recommended for production release? I would appreciate guidance on the correct usage. If these issues are expected to persist, I'm wondering if I should continue using the existing CLCircularRegion API instead. Any insights or recommendations would be greatly appreciated.

[Regression] Core Location underground positioning inaccurate on iOS 26.1 beta (23B5044i)
Summary While parallel testing Core Location on the new iOS 26.1 beta (23B5044i), I observed what I believe to be a regression of the issue described here: https://developer.apple.com/forums/thread/779192 Specifically, user positioning underground subway stations is noticeably inaccurate on the beta, whereas the same scenarios remain accurate on the unupgraded device below. I work with the MTA (New York City) and work with the OP of that thread. Happy to provide additional testing or details if helpful. Please let me know what else you need. Test Info Riding NYCT from Wall St to 34th St Penn Station on the 2 train carrying two iphones Recording: https://limewire.com/d/dpTWi#pDC3GRYIdE Expected: Consistent underground positioning comparable to prior releases. Actual: Degraded/inaccurate underground positioning on iOS 26.1 beta. Test Devices Left Screen: iPhone 15 Pro Max - iOS 26.1 beta (23B5044i) Right Screen: iPhone 11 - iOS 18.6.2 (22G100) Blue dots show location set by CoreLocation. Red dot on iphone 11 shows the actual location of both devices as I was able to manually place while travelling through a station. Placement through tunnels is not easy to verify and not usually indicated. Timestamps Comparison of when train was actually observed in a station vs when 26.1 and 18.6.2 CoreLocation updated to the station Fulton St 1:48 iOS 26.1 correctly updates (correctly) 2:16 iOS 18.6.2 updates (28sec late) Park Place 4:12 train arrives 4:15 iOS 18.6.2 updates to ~near Park Place 5:04 iOS 18.6.2 updates to Park Place (correctly) 6:07 iOS 26.1 update to ~near Park Place (over 2 mins late) Chambers St 6:02 train arrives / iOS 18.6.2 updates (correctly) 6:14 iOS 26.1 updates to ~near Chambers 6:18 iOS 26.1 update to Chambers (correctly) Franklin St 6:52 train arrives 6:55 iOS 18.6.2 updates (correctly) x:xx iOS 26.1 does not update Canal St: 7:16 train arrives 7:18 iOS 18.6.2 updates (correctly) x:xx iOS 26.1 does not update Houston St 7:54 train arrives 8:00 iOS 18.6.2 updates (correctly) x:xx iOS 26.1 does not update Christopher St 8:37 iOS 26.1 presumably between Houston St and Christopher St 8:40 train arrives / iOS 18.6.2 updates (correctly) x:xx iOS 26.1 does not update 14 St 9:22 train arrives 9:28 iOS 18.6.2 updates (correctly) 11:01 as train departs station iOS 26.1 updates (1.5 mins late)

iOS 26: Maps share sheet no longer provides com.apple.mapkit.map-item and only shares short maps.apple/p/... URLs (how to get coordinates?)
Since iOS 26, the Apple Maps share sheet no longer provides a com.apple.mapkit.map-item attachment when sharing a location to my Share Extension. Additionally, on real devices the shared URL is now a short link (https://maps.apple/p/...), which does not contain coordinates. On the simulator, the URL still includes coordinates (as in previous iOS versions). I'm trying to find the official or recommended way to extract coordinates from these new short URLs. Environment: Devices: iPhone (real device) on iOS 26.0 / 26.0.1 Simulator: iOS 26.0 / 26.0.1 simulator (behaves like iOS 18 — see below) App: Share Extension invoked from Apple Maps -> Share -> my app Xcode: 26.0.1 Steps to Reproduce Open Apple Maps on iOS 26 (real device). Pick a POI (store/restaurant). Share -> choose my share extension. iOS 18 and earlier (lldb) po extensionContext?.inputItems ▿ Optional<Array<Any>> ▿ some : 1 element - 0 : <NSExtensionItem: 0x60000000c5d0> - userInfo: { NSExtensionItemAttachmentsKey = ( "<NSItemProvider: 0x600002930d20> {types = (\"public.plain-text\")}", "<NSItemProvider: 0x600002930c40> {types = (\"com.apple.mapkit.map-item\")}", "<NSItemProvider: 0x600002930bd0> {types = (\"public.url\")}" ); } Typical URL: https://maps.apple.com/place?address=Apple%20Inc.,%201%20Apple%20Park%20Way,%20Cupertino,%20CA%2095014,%20United%20States&coordinate=37.334859,-122.009040&name=Apple%20Park&place-id=I7C250D2CDCB364A&map=explore iOS 26 (lldb) po extensionContext?.inputItems ▿ 1 element - 0 : <NSExtensionItem: 0x6000000058d0> - userInfo: { NSExtensionItemAttachmentsKey = ( "<NSItemProvider: 0x600002900b60> {types = (\"public.url\")}", "<NSItemProvider: 0x600002900fc0> {types = (\"public.plain-text\")}" ); } URL looks like: https://maps.apple/p/U8rE9v8n8iVZjr On simulator iOS 26 same missing map-item provider - but the URL is still long and contains coordinates, like this: https://maps.apple.com/place?coordinate=37.334859,-122.009040&name=Apple%20Park&.. Issue The short URLs (maps.apple/p/...) cannot be resolved directly - following redirects ends with: https://maps.apple.com/unsupported The only way I've found to get coordinates is to intercept intermediate redirects - one of them contains the expanded URL with coordinate=.... Example of my current workaround: final class RedirectSniffer: NSObject, URLSessionTaskDelegate { private(set) var redirects: [URL] = [] func urlSession(_ session: URLSession, task: URLSessionTask, willPerformHTTPRedirection response: HTTPURLResponse, newRequest request: URLRequest) async -> URLRequest? { if let url = request.url { redirects.append(url) } return request } } Then I look through redirects to find a URL containing "coordinate=". This works, but feels unreliable and undocumented. Questions Was the removal of com.apple.mapkit.map-item from the Maps share payload intentional in iOS 26? If yes, is there a new attachment type or API to obtain an MKMapItem? What’s the official or supported way to resolve https://maps.apple/p/... to coordinates? Is there any MapKit API or documented URL scheme for this? Is intercepting redirect chains the only option for now? Why does the iOS 26 simulator still return coordinate URLs, while real devices don't?

iOS26+, MKMapview crash
I have a UIViewController that uses MKMapview to display the motion history trajectory. Repeatedly entering and exiting UIViewController will cause a crash, and the crash stack is as follows: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Subtype: KERN_INVALID_ADDRESS at 0x000000014bfc0fc8 Exception Codes: 0x0000000000000001, 0x000000014bfc0fc8 VM Region Info: 0x14bfc0fc8 is not in any region.

I have also tested on iOS 15, 16, and 18 without any issues. Could this be an error in the iOS 26 system? Have you ever met any friends? I hope to receive an answer. Thank you.
