Apple's push cannot receive information, use the open-source library JdSoft. Apple.Apns.Notifications Because I am not familiar with it, I modified Tls12. Does anyone know how to modify this open-source library to achieve push functionality apnsStream.AuthenticateAsClient(this.Host, this.certificates, System.Security.Authentication.SslProtocols.Tls12, false)

Hi, I'm unable to install provisioning profile on my iPad and I know the xcode component iOS/iPadOs version and iPadOS version should be same or below the latest compared to xcode components. Now the issue is xcode component version is iOS 18.4 (22E235) SDK + iOS 18.4 (22E238) Simulator (Installed) and iPadOS version is iOS 18.4.1(22E252) could this be cause of issue ? If yes then when will apple release components for 18.4.1? Because iOS 18.4.1 release at least 3-4 weeks before this post.

Dear Developers, I am having some problems with Reality Composer Pro on Mac. Specifically, I don't understand how to manage some timeline functions. I have an object that has a double animation, an opening animation and a closing animation. On a first tap the object should open through animation 1, while on the second tap the object should close through animation 2. Only the two animations conflict. In addition, animation 1 does not stop at the last frame but returns the object to the position of frame 0. Do you have any solutions? Thank you all

The flags like #if DEBUG ... endif are dependent on the Active Compilation Conditions. So if they say DEBUG the enclosed code block will be executed, otherwise not. Now I have the phenomenon that a #DEBUG block in a Package does not evaluate these conditions. It rather depends on the name of the configuration used to build. So if I build my app with Active Compilation Condition set to DEBUG, but the configuration name is something like App-Release, the DEBUG block in my Package is not added/executed. The ones which are directly in the project are added. Vice versa if the Compilation Condition say RELEASE but the configuration is called App-Debug the blocks in the Package are added to the compilation, but the ones in the project itself are not It suffices that the config name contains the word Debug for this to happen. E.g. the configuration App-Release-Debug (I know that this would be stupid, but it is for demonstrating purposes) will cause the Packages to include the DEBUG blocks. This happens no matter what you set in the Build Settings of the project and/or target. The Packages are added via GitHub/GitLab Source Control with SPM. Any ideas why this behaves like it does? It doesn't seem like it should...

I've recently upgraded my project from Xcode 15 to Xcode 16. Without changing any build settings or compiler flags, I noticed that the final executable size has increased significantly when building the same C++ code. Investigation: To investigate further, I compared the Link Map outputs from both versions of Xcode. One key difference I found: The symbol size for std::sort increased from 4,336 bytes (Xcode 15) to 6,084 bytes (Xcode 16) – a ~40% increase. This seems to be part of a broader trend where other standard library symbols are also taking up more space in the binary when built with Xcode 16. Questions: Has Apple Clang or libc++ in Xcode 16 changed the implementation of STL algorithms like std::sort? Are there changes in inlining, template instantiation, or debug info that could explain the increase? Is this expected behavior? If so, is there any guidance on minimizing the binary size regression?

Hi, You're here because your project has issues related to Xcode Previews or Swift Previews. The issue you're experiencing may be the result of any of the following: An error in your SwiftUI app, Xcode previews, or on-device previews. A configuration error in your Xcode project, including any third-party dependencies or packages. A system issue in the operating system, SwiftUI, or in Xcode Previews. Based on your request, I need more information about your SwiftUI app when rendering Xcode Previews or on-device previews. Specifically, I’ll need the diagnostics Swift Previews generates to make sure I understand the error encountered by the preview system. Please create a report in Feedback Assistant to share the details requested in the instructions below. For issues with macOS, Mac Catalyst, on-device iOS, or on-device visionOS previews, perform the following steps to gather diagnostics: Download and install the Swift Previews logging profile for your device. Reproduce the error while previewing on device, taking note of the timestamp when the error occurred. Attach the Previews diagnostics, sysdiagnose from your Mac, a sysdiagnose from the previewing iOS or visionOS device. For issues with Xcode Previews, perform the following steps to gather diagnostics: Download and install the Swift Previews logging profile for your device. Reproduce the error in Xcode Previews, if you haven’t already done so. If an error banner appears in the canvas, click the "Diagnostics" button within the banner, then go to Step 5; otherwise, continue to Step 4. If the error banner is missing, navigate to the menu in Xcode: Editor > Canvas > Diagnostics In the presented sheet, click the "Generate Report" button. Attach a zip file containing the diagnostic report to your bug report (it will be named something like previews-diagnostics-0123456789.zip). Submitting your feedback Before you submit to Feedback Assistant, please confirm the following information is included in your feedback: with the Swift Previews logging profile installed, attach the sysdiagnose logs gathered after reproducing the issue the Previews diagnostics generated by Xcode timestamp identifying when the issue was reproduced focused sample Xcode project that reproduces the issue (if applicable) screenshots or videos of the error (optional) Please include all requested information to prevent delays in my investigation. After your submission to Feedback Assistant is complete, please respond to your original Forums post with the Feedback ID. Once received, I can begin my investigation and determine if this issue is caused by an error within your SwiftUI app, a configuration issue within your Xcode project, or an underlying issue in the operating system, SwiftUI, in Xcode Previews, or on-device previews.

When I thought Xcode could not get any worse, here's the most absurd thing I have ever seen developing software in almost 20 years of work. When building a project, which I haven't touched lately, and last time it was building just fine, it raised errors on a class that doesn't even belong in any way to such project, it only exists in another one. To clarify, we're talking of a project written in C++ which runs only on mac, which is failing due to linker errors, where the linker can not find symbols of a class living in a different project and that is not referenced in any way inside this project. I mean, really? how does Apple manage to make Xcode more and more unstable by the minute? Starting from Xcode 15.1 I was already experiencing much longer building times, due to the fact that it doesn't manage the cache properly and is rebuilding lots of stuff every time..

The following function could run several hundred times with no problem but will occasionally cause a EXC_BAD_ACCESS (SIGBUS). The last time it was a KERN_PROTECTION_FAILURE perhaps meaning it is trying to write to a read only memory but previously it was KERN_INVALID_ADDRESS. I have tried debugging tools to no avail. Can anyone see any reason why the following function could be causing this. Just in case the function is a red herring the only other thing that was running is a AVQueuePlayer that contains 11 tracks, but the crash happens mid song making it unlikely. The function includes running other functions so below is all related functions that happen as a result of a swipe gesture. func completeLeft() { let add1 = Int(tiles[Square - (squares2move + 2)].name ?? "0") ?? 0 let add2 = Int(currentNode.name ??

I updated the icons in Xcode to customize the appearance of my app icons to be light, dark, or tinted. The app is allowed to be downloaded and run on iPadOS. The app icon behaves as expected on iOS however the app icon does not change on the iPad. Am I missing a step for the iPad? To be clear the app does not target iPadOS rather it is just running the iOS version. Thanks kof

I'm trying to evaluate if we can support AR navigation with MapKit. The feature is supposed to be available for users in US. I tried to run the sample on my iPhone: https://developer.apple.com/documentation/arkit/tracking-geographic-locations-in-ar?language=objc But I'm in a location that ARGeoTrackingConfiguration.checkAvailabilityWithCompletionHandler: always return false. I think ARGeoAnchor isn't supported in my location. I tried to use simulated locations by Adding a gpx file when launching the app. Enabling Xcode -> Debug -> Simulate Location -> New York, NY, US But the availability for ARGeoAnchor is still false. Is that possible for me to develop the ARGeoAnchor feature outside of the covered areas?

I have an iOS app, and I am trying to add a companion WatchOS app. My iOS app depends on 2 libraries: GoogleMobileAds FirebaseAnalyticsWithoutAdIdSupport When I add a new target for WatchOS, the preview build starts to fail. I am not adding any libraries to WatchOS. The Google Ads and Firebase Analytics libs are only under the iOS target. I am unable to run the preview, I get an error when trying to build the watch scheme. The preview does not work. The build just crashes. I've included the error log below. But, here are the steps I've tried so far: Delete folders inside Derived Data Run a clean build (Cmd + Option + Shift + K) Delete scheme and create a new one Reset Package Cache Restart Xcode Restart Macbook But, it just does not work. I do not understand why the watchOS target is erroring for "GoogleUserMessagingPlatform" and "GoogleMobileAdsTarget" when those packages are not linked/used for the watchOS. SchemeBuildError: Failed to build the scheme “timerWatch Watch App” While building for watchOS Simulator, no library for this platform was found in '/Users/k/Library/Developer/Xcode/DerivedData/timer-dhkdhvfcqtfgskfdxpmupujswtuh/SourcePackages/artifacts/swift-package-manager-google-user-messaging-platform/UserMessagingPlatform/UserMessagingPlatform.xcframework'.

Hi, I am getting an error stating "Argument passed to call that takes no arguments". I want this Apple Watch App to measure and store RR Intervals from the PPG sensor on the Apple Watch for Heart Rate Variability calculations. Please help me fix this, I can't figure it out. Here is my code: heartbeatQuery = HKHeartbeatSeriesQuery(predicate: predicate, dataReceivedHandler: { (query, timeSinceLastBeat, ended, error) in // Switch to main thread for UI updates DispatchQueue.main.async { if let error = error { print("Heartbeat query error: (error.localizedDescription)") self.fetchErrorMessage = "Heartbeat query error: (error.localizedDescription)" // Consider stopping the workout session if the query fails critically // self.stopWorkoutSession() return } if ended { print("Heartbeat query indicates series ended.") } // Append valid RR intervals if timeSinceLastBeat > 0 { self.rrIntervals.append(timeSinceLastBeat) self.beatCount += 1 } } // End DispatchQueue.main.async }) // End query data handler // --- END OF PROBLEMATIC INITIALIZER --- // Execute the query if it was created successfully It recommends the fix as removing this part: '(predicate: predicate, dataReceivedHandler: { (query, timeSinceLastBeat, ended, error) in // Switch to main thread for UI updates DispatchQueue.main.async { if let error = error { print("Heartbeat query error: (error.localizedDescription)") self.fetchErrorMessage = "Heartbeat query error: (error.localizedDescription)" // Consider stopping the workout session if the query fails critically // self.stopWorkoutSession() return } if ended { print("Heartbeat query indicates series ended.") } // Append valid RR intervals if timeSinceLastBeat > 0 { self.rrIntervals.append(timeSinceLastBeat) self.beatCount += 1 } } // End DispatchQueue.main.async })' But after I remove that it says "Cannot assign value of type 'HKHeartbeatSeriesQuery.Type' to type 'HKHeartbeatSeriesQuery'" PLEASE HELP ME Thanks

Example: I have a state var curHighScore declared in ContentView. I select it, right click and select "Find Selected Symbol in Workspace" The result is : 1 resul in 1 file, i.e. the line of declaration of the var But obviously, the same var is used at line #102: How come this occurence is not found by the search command. Such happens every now and then. Is there something I am missing ? What is causing this ? Thanks for your help.

the Xcode Version 16.2 (16C5032a), I want to know how to setup a directory in Xcode project when develop the iOS app. Here is the whole thing: I start a new iOS App project "test_path". then I right click, and choose "New Folder", to make a new folder "configx" then I right click on the configx folder, and choose the "add files to test_path", add a file in it But the folder does not exist in the project when try to access by "Bundle.main.urls" func. 5. when ls in the Mac, /data/Containers/Bundle/Application/E4F11903-3FAD-467F-A4CD-60AC68D64934/test_path.app, the file just at the root path of test_path.app, no "configx" folder ahead the file. so, how to setup a directory or a path in iOS project?

We’re developing an iPad application that visualizes 2D and 3D building floor plans, including a mesh network of nodes that control lighting and climate. The node count ranges from 1,000 to 15,000. We’re using SceneKit to dynamically render the floor plan and node mesh on an iPad 10th generation running iPadOS 18.3. While the core visualization works, we are experiencing significant performance degradation as the node count increases. Specifically: At 750–1,000 nodes, UI responsiveness noticeably declines. At 2,000 nodes, navigating the floor plan becomes nearly unusable. We attempted to optimize performance with a Geometric Pool algorithm, but the impact was minimal. Strangely, the same iPad handles 30,000+ 3D objects effortlessly when using Unity or Unreal Engine, raising the question of whether SceneKit may not be optimized for this scale. Our questions: Is SceneKit suitable for visualizing such large node counts, or are we hitting an inherent limitation of the framework? Are there best practices or optimization techniques for SceneKit that we might be missing? Should we consider a hybrid approach or fully transition to a different 3D engine for this use case? We’ve attached a code sample below demonstrating the issue. Any insights, suggestions, or experiences would be greatly appreciated! ContentView.swift

I have the 'warnings as errors' policy set to Yes for Apple Clang and Swift compiler. As far as I know, there is no way to make exceptions to the warning policies from Swift compiler (correct me if I am wrong), what about Clang warning policies, specifically when it comes to header files from 3rd party pods? They don't show up on the Compile Sources so I can't apply flags such as -Wno-error=deprecated to them. Adding #pragma GCC... to them won't help as a fresh pod install will wipe the #pragma statements out. Is there a way to exclude the header files from pods from getting the warning policies from Clang so I won't see errors from them when compiling Clang modules that's a part of the build process?

Hi all, I’m running into an issue with my iOS + Apple Watch app project, and I could really use some advice. My WatchOS app requires an iOS companion for settings and configuration, so both apps need to be distributed together. Here’s how I structured my Xcode project: Main iOS App target WatchOS App target WatchOS Extension target However, I’m very confused about how these targets interact, and things are not working as expected. The problem: I can build and run the WatchOS app and its extension independently in the simulator by selecting their schemes. When I select the main iOS app scheme, I get an error about ITSWatchOnlyContainer in the Info.plist—even though there’s no Info tab for that target in Xcode. I’m able to distribute the WatchOS app by itself, and the extension as well. But I can’t distribute them bundled together as a single package, and I haven’t found any clear resources that explain how to fix this. This is my very first app, and it’s frustrating to get stuck just before the finish line! Project Structure / steps to reproduce Let’s say my project is called MyAppProject, with these targets: MyAppProject Main iOS App Embedded target: MyAppProject Watch App Bundle identifier: com.example.MyAppProject MyAppProject Watch App WKCompanionAppBundleIdentifier: com.example.MyAppProject “Requires iOS App”: YES MyAppProject Extension Bundle identifier: com.example.MyAppProject When running from the MyAppProject scheme, I get this error (even though I can’t see or edit the Info.plist in Xcode for this target): “Please try again later. This app has the ITSWatchOnlyContainer key set in its Info.plist, which identifies it as a shell app surrounding a Watch-only app; these are not installable.” As a result, I can’t distribute the app as a bundle. I’d appreciate help understanding: How should the Info.plist files be configured for each target? What do I do if the Info.plist path seems missing in the Xcode UI? Is there a “correct” way to structure an iOS + WatchOS app for bundled distribution?

When Xcode 16.2 connects iPad to real machine debugging using the view in the picture box, the mac will be stuck directly, the computer cursor will disappear, and the computer cannot do any operation
