Hi all, I’m running into a persistent linker error when building my Unity 6 project (IL2CPP, iOS target) that calls a Swift method via an Objective-C++ wrapper. Despite following all known steps, I keep getting: Undefined symbols for architecture arm64: "_placeGeoAnchor", referenced from: _GeoAnchorTrigger_placeGeoAnchor in libGameAssembly.a ... ld: symbol(s) not found for architecture arm64 I’m trying to place a persistent AR anchor at real-world GPS coordinates (so that the same asset can appear at the same location for a returning user). Since I’m targeting iOS, I can’t use Google’s geospatial anchors (but I sooo wish I could--please apple I beg of you stop being so selfish lol). I've already done these things: Swift file is added to Unity-iPhone target. .mm and .h files are in Unity-iPhone target under Compile Sources. Bridging header is set to Unity-iPhone-Bridging-Header.h. Generated header name is correct (GeoTest-Swift.h). Build Active Architecture Only set to No. Function has attribute((visibility("default"))). Unity project uses IL2CPP scripting backend. Yet I'm still getting the same linker error — it appears Unity (via IL2CPP) references the function, but Xcode doesn't link it. It’s something small that’s being missed with how IL2CPP links native symbols? Or maybe I need to explicitly include something in Link Binary With Libraries? I’ve verified symbol visibility and targets repeatedly. I’ve built AR features in Unity before (for Quest), but this is my first time trying to bridge C# → Objective-C++ → Swift in this way for a geolocation-based AR anchor for an iphone. I'm going crazy, I’ve been stuck on this for 12+ hours now, so any insight or nudge would be deeply appreciated. SPECS: Macbook Pro M4 Pro--Sequoia 15.4 Unity 6000.0.45f1 IPhone 11 iOS 18.4 Xcode 15

For Xcode 15 and Xcode 16, whenever I try to use the Refactor->Rename command I get a spinning busy cursor for a short while then I get an alert that says: Rename Failed Refactoring engine failure. This happens on several projects and I've tried removing the derived data folder, but am at a loss to find additional troubleshooting steps. Are there other files I might remove or reset to get my "Refactoring Engine" back into shape?

After developing the IOS app using XCode, I https://aninterestingwebsite.com/account/resources/identifiers/list Created Identifiers (HanBaoAI) and locally created Certificate SigningRequest.certSigningRequest https://aninterestingwebsite.com/account/resources/certificates/list Created Certificates (Expiry Date 2026/04/21) and also created profiles (HanBaoAI, Expires 2026/04/21), and then https://appstoreconnect.apple.com/apps I created an app (HanBaoAI) and uploaded it to the official website using Product Archive in xcode. The upload was successful, but the official website's testflight showed 1 (processing). When I refreshed the page, there was no information in testflight. May I ask what the reason is? How to solve it? Please provide complete and detailed solution steps.

We have started facing an issue after updating Xcode from version 15.2 to 16, we have a voip application with webview and call kit, and we have the Background Modes capabilities: Voip, Audio, Background fetch, and Background processing. We had no problem on Xcode 15, but ever since updating Xcode 16 and sdk 18, when app goes into the background during an active call, the app is suspended and no events are triggered UNTIL the app is resumed to the foreground.

I am new to Xcode and trying to learn how to use Metal for my internship. I am trying to link the binaries of Foundation.framework, Metal.framework, and Quartcore.framework. But whenever I try to build it always fails to find any of them. I have my Header Search Path as $(PROJECT_DIR)/metal-cpp, I tried adding some for the Frameworks but that did not work either. I do have the binaries linked in the Build Phases, so I don't know what else I could be missing.

Hi, I am currently working on a MacOS App, where I need the undistortion function of opencv. But after I tried to add opencv to my project, I get following error: unexpected service error: The Xcode build system has crashed. Build again to continue. Cleaning the build folder also doesn't help. Does anyone have an idea what could be the issue? Ryan

Hi , I am currently encountering issues while running a Titanium application using Xcode 16. I would like to request your guidance on resolving the following problems: When running the Titanium app on a real device, I receive the following warning in Xcode and the app does not proceed beyond this point and the app is crashing on launch. warning: (arm64) /Users/Library/Developer/Xcode/DerivedData/Procedures-hamsarmfbtnowbcdocpmydtuafnp/Build/Products/Debug-iphoneos/Procedures.app/Procedures empty dSYM file detected, dSYM was created with an executable with no debug info. Thank you

When I use Xcode to develop the apps, the connection to my own Apple Watch is failed. The simulator has been downloaded, but it still displayed"watchOS10.0 Not Installed". The developer options were opened, I click the"trust this computer" but it always display"Connecting to *** Apple Watch". My iPhone can be connected normally.

What I am trying to do is very simple. Environment description: macOS Catalina version 10.15.7 iOS Simulator version 12.3 Target device iPhone 11 (iOS 13.2.2) Open Safari > go to website > mictests.com Result: "Could not find any media devices. It is very likely that your browser does not allow access to these devices." The Simulator does have access to the microphone. I can use Siri just fine. Only Safari cannot access the mic. I'm really stuck here, any ideas are welcome.

Hello All, I see an issue while running the Notification content Extension on simulator without checking the "Copy only when installing in app target -> Build Phases -> Embed App Extensions" If I check "Copy only when installing in app target" then only it is working. Can someone please confirm if Notification Content Extension is working on simulator. If yes how can we do that. Please share the details

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.

Start from clean iOS 18.4 simulator. Application tried to request authorisation from user for microphone access. Clicking allow caused the application crashed. Used Swift 6. Report Identifier FB17686864.

I am having issues loading my model from a Swift Package with the following structure: | Package.swift | Sources | - | SamplePackage | - | - Core | - | - | - SamplePackageDataStack.swift | - | - | - DataModel.xcdatamodeld | - | - | - | - Model.xcdatamodel ( <- is this new? ) As mentioned, I am not required to list the xcdatamodeld as a resource in my Package manifest. When trying to load the model in the main app, I am getting CoreData: error:  Failed to load model named DataModel Code: In my swift Package: public class SamplePackageDataStack: NSObject {     public static let shared = SamplePackageDataStack()     private override init() {}     public lazy var persistentContainer: NSPersistentContainer = { let container = NSPersistentContainer(name: "DataModel") container.loadPersistentStores(completionHandler: { (storeDescription, error) in             if let error = error as NSError? {                 fatalError("Unresolved error \(error), \(error.userInfo)")             }         })         return container     }()     /// The managed object context associated with the main queue.

If you need help investigating a crash, please include a crash report in your post. To smooth things along, follow these guidelines: For information on how to get a crash report, see Acquiring crash reports and diagnostic logs. Include the whole crash report as a text attachment (click the paperclip icon and then choose Add File). This avoids clogging up the timeline while also preserving the wealth of information in the crash report. If you’re not able to post your crash report as an attachment, see Can’t Post Crash Report as Attachment below. If you want to highlight a section of the report, include it in the main body of your post. Put the snippet in a code block so that it renders nicely. To create a code block, add a delimiter line containing triple backquotes before and after the block, or just click the Code Block button. If possible, post an Apple crash report. Third-party crash reporters are often missing critical information and have general reliability problems (for an explanation as to why, see Implementing Your Own Crash Reporter). Symbolicate your crash report before posting it. For information on how to do this, see Adding identifiable symbol names to a crash report. If you need to redact the crash report, do so consistently. Imagine you’re building the WaffleVarnish app whose bundle ID is com.example.wafflevarnish but you want to keep your new waffle varnishing technology secret. Replace WaffleVarnish with WwwwwwVvvvvvv and com.example.wafflevarnish with com.eeeeeee.wwwwwwvvvvvvv. This keeps the text in the crash report aligned while making it possible to distinguish the human-readible name of the app (WaffleVarnish) from the bundle ID (com.example.wafflevarnish). Finally, for information on how to use a crash report to debug your own problems, see Diagnosing issues using crash reports and device logs. Can’t Post Crash Report as Attachment Crash reports have two common extensions: .crash and .ips. If you have an .ips file, please post that [1]. DevForums lets you attach a .crash file but not an .ips file (r. 117468172). To work around this, change the extension to .txt. If DevForums complains that your crash report “contains sensitive language”, leave it out of your initial post and attach it to a reply. That often avoids this roadblock. If you still can’t post your crash report, upload it to a file sharing service and include the URL in your post. Post the URL in the clear, per tip 14 in Quinn’s Top Ten DevForums Tips. Getting a Crash Report from the Xcode Organiser The Xcode organiser shows crash reports from customers. If you’re investigating such a crash and want to post a crash report: Navigate to the crash in the Xcode organiser. Note If you can’t see the right crash, check the filter popups at the top. In the list of crashes, secondary click on your crash and choose Show in Finder. That reveals the Xcode crashpoint document (.xccrashpoint) in the Finder. Secondary click on that and choose Show Package Contents. In the resulting Finder window, find a crash report (.crash) that accurately represents the crash you’re investigating and attach that to your forums post. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" [1] Because it’s easy to go from an .ips file to a .crash file. I usually do this by choosing File > Quick Look in the Finder. For more info about these file formats, see this post. Revision History: 2025-08-29 Added the Getting a Crash Report from the Xcode Organiser section. 2024-11-21 Added a recommendation to post the .ips format if possible. 2024-05-21 Added some advice regarding the “contains sensitive language” message. 2023-10-25 Added the Can’t Post Crash Report as Attachment section. Made other minor editorial changes. 2021-08-26 First posted.

I'm creating a .xcframework in order to deliver an api/functionality to a customer for inclusion into an app. I'm doing it as a .xcframework as I want it to be a binary so that the source code isn't accessable. The xcframework has dependencies on modules which are installed via SPM (there are a few, an example is PhoneNumberKit) When I build the xcframework and then add it to a test program and invoke its api then there's a run time error saying "PhoneNumberKit/resource_bundle_accessor.swift:44: Fatal error: unable to find bundle named PhoneNumberKit_PhoneNumberKit" How can I build the xcframework so that its dependencies are included within it? (Stepping back a bit, is an xcframework an appropriate approach for this?)

Do simulators match real device for pixel density for testing image assets?
