1. The Inquiry Hello, I have been implementing a background geofencing feature and, during testing, I found a significant numerical difference in event callback frequency between the older CLCircularRegion API and the newer CLMonitor API (CLMonitor.CircularGeographicCondition), introduced in iOS 17. My testing was strictly conducted using the Always Allow location permission (requestAlwaysAuthorization()). I used both APIs in parallel under identical geofencing conditions and within the same implementation environment. Since a clear difference persists in the data, I suspect this may stem from structural differences in the internal mechanisms of the two APIs rather than an implementation error on my part. 2. Environment and Implementation Details (Proof of Integrity) I have ensured that my implementation adheres to Apple's guidelines and uses modern Swift concurrency features. A. Development Environment and Permissions iOS Version: iOS 18.x and later Xcode Version: Version 17A400 (Version 26.0.1) Loc

I got several reports about our TestFlight app crashing unconditionally on 2 devices (iOS 18.1 and iOS 18.3.1) on app start with the following reason: Termination Reason: DYLD 4 Symbol missing Symbol not found: _$sScIsE4next7ElementQzSgyYa7FailureQzYKF (terminated at launch; ignore backtrace) The symbol in question demangles to (extension in Swift):Swift.AsyncIteratorProtocol.next() async throws(A.Failure) -> A.Element? Our deploy target is iOS 18.0, this symbol was introduced in Swift 6.0, we're using latest Xcode 16 now - everything should be working, but for some reason aren't. Since this symbol is quite rarely used directly, I was able to pinpoint the exact place in code related to it. Few days ago I added the following code to our app library (details omitted): public struct AsyncRecoveringStream: AsyncSequence { ... public struct AsyncIterator: AsyncIteratorProtocol { ... public mutating func next(isolation actor: isolated (any Actor)? = #isolation) async throws(Failure) -> Element? { ...

When a static library is built with Xcode 26 (with deployment target set to iOS 13) and then linked into an app project compiled with Xcode 16, the build process fails with the following linker error: Undefined symbols for architecture arm64: _swift_coroFrameAlloc This occurs even though both the static library and the app project have their deployment targets set to iOS 13.0. The static library works on Xcode 26, but fails to link on Xcode 16. This issue shows up with certain Swift syntax. For example, in my case, using a property getter and setter caused the compiler to emit a reference to _swift_coroFrameAlloc, which in turn triggered the issue. This issue prevents us from distributing pre-built static libraries compiled with Xcode 26 to teammates who are still using Xcode 16. I’ve filed feedback for this issue (FB21130604). Is there any way to work around it? For example, by adding specific Build Settings or something similar? A demo project is availab

I’m running Xcode 26.1.1 (17B100) with deployment target iOS 18.0+, and I’m seeing a consistent and reproducible issue on real devices (iPhone 13 Pro, iPhone 15 Pro): Problem The first time the user taps into a TextField or a SwiftUI .searchable field after app launch, the app freezes for 30–45 seconds before the keyboard appears. During the freeze, the device console floods with: XPC connection interrupted Reporter disconnected. { function=sendMessage, reporterID=XXXXXXXXXXXX } -[RTIInputSystemClient remoteTextInputSessionWithID:performInputOperation:] perform input operation requires a valid sessionID. inputModality = Keyboard customInfoType = UIEmojiSearchOperations After the keyboard finally appears once, the issue never happens again until the app is force-quit. This occurs on device Reproduction Steps Minimal reproducible setup: Create a new SwiftUI app. Add a single TextField or .searchable modifier. Install Firebase (Firestore or Analytics is enough). Build and run on device. Tap the text fie

Provisioning profiles created for my App ID are not including the Push Notifications capability, even though Push Notifications is enabled in the App ID configuration in Apple Developer Portal. I have enabled Push Notifications for my App ID (com.abc.app) in the Apple Developer Portal. The capability shows as enabled and saved. However, when provisioning profiles are generated (either manually or through third-party tools like Expo Application Services), they do not include: The Push Notifications capability The aps-environment entitlement This results in build failures with the following errors: Provisioning profile *[expo] com.abc.app AppStore [timestamp] doesn't support the Push Notifications capability. Provisioning profile *[expo] com.abc.app AppStore [timestamp] doesn't include the aps-environment entitlement. Steps Taken ✅ Enabled Push Notifications in App ID configuration (com.mirova.app) ✅ Saved the App ID configuration multiple times ✅ Waited for Apple's systems to sync (waited 5-10 minutes) ✅ Remov

Hi everyone, I am building a React Native iOS app that discovers audio devices on the local Wi-Fi network using UDP broadcast + mDNS/Bonjour lookup (similar to the “4Stream” app). The app works 100% perfectly in Debug mode when installed directly from Xcode. But once I upload it to TestFlight, the local-network features stop working completely: UDP packets never arrive Device discovery does not work Bonjour/mDNS lookup returns nothing Same phone, same Wi-Fi, same code → only Debug works, TestFlight fails react-native-udp for UDP broadcast react-native-dns-lookup for resolving hostnames react-native-xml2js for parsing device responses

I've made my updated icon and I try to import it to Xcode but it keeps crashing even if I clean the project/delete derived data or try to add through the Naivgation Controls. I've tried with the Xcode 26.2 beta too but it has the same issue.
