I'm trying to figure out how to debug this issue. I have a fairly simple program that I built using the Hello World sample code as reference. Here is my code: import SwiftUI @main struct Core_USDZ_ViewerApp: App { var body: some Scene { // Main Menu scene // WindowGroup (id: "main-menu"){ CoreUsdzMenu() } // Scene that takes data as an input // for volumetric viewing // WindowGroup (for: URL.self) { $content in CoreUsdzVolume(url: content) } defaultValue: { URL(string: "https://developer.apple.com/augmented-reality/quick-look/models/pancakes/pancakes.usdz")! } .windowStyle(.volumetric) .defaultSize(width: 0.2, height: 0.3, depth: 0.3, in: .meters) // Full surround scene /* ImmersiveSpace { // put our immersive view here } */ } } In the simulator, this launches the main menu scene, but when installed on the Vision Pro using TestFlight it skips the main menu and goes straight to the second WindowGroup. Since the data isn't populated, it uses the defaultValue and just shows pancakes. I'm having trouble logging and debugging this issue, as I don't have access to the hardware myself. I have to push the code to TestFlight and wait for a coworker to test it. Does anyone have ideas of why this could be happening? Any help is appreciated. Logging and debugging tips especially. I'm used to just putting log messages in my code to debug, but maybe there are some breakpoint techniques I should be using here or something. Oh, also, here is my CoreUsdzMenu script: import SwiftUI import RealityKit import UniformTypeIdentifiers struct CoreUsdzMenu: View { @Environment(\.openWindow) private var openWindow @Environment(\.dismissWindow) private var dismissWindow @State var entity: Entity? = nil @State var showFilePicker: Bool = false init() { NSLog("In CoreUsdzMenu") } var body: some View { VStack{ Text("Core USDZ Viewer v1.1") .font(.title) .frame(width: 500.0, height: 100.0) /* usdz list HStack(spacing: 100.0) { Spacer() // Load the UsdzList view into the window! UsdzList() Spacer() }*/ /* button test for window Button { openWindow(value: usdzData[1].url) } label: { Text("open test window") }*/ // A view for displaying the loaded asset. /* RealityView( make: { content in // Add a placeholder entity to parent the entity to. // let placeholderEntity = Entity() placeholderEntity.name = "$__placeholder" if let loadedEntity = self.entity { placeholderEntity.addChild(loadedEntity) } content.add(placeholderEntity) }, update: { content in guard let placeholderEntity = content.entities.first(where: { $0.name == "$__placeholder" }) else { preconditionFailure("Unable to find placeholder entity") } // If there is a loaded entity, remove the old child, // and add the new one. // if let loadedEntity = self.entity { placeholderEntity.children.removeAll() placeholderEntity.addChild(loadedEntity) } } )*/ // A button that displays a file picker for loading a USDZ. // Button( action: { showFilePicker = true }, label: { Text("Load USDZ") } ) .padding() } // can import usdz and realityFile UTT types .fileImporter(isPresented: $showFilePicker, allowedContentTypes: [.usdz, .realityFile]) { result in // Get the URL of the USDZ picked by the user. // Guarded for errors. // guard let url = try? result.get() else { print("Unable to get URL") return } NSLog("In CoreUsdzMenu") // add new .usdz to our data list // for later!~ // use Observables n stuff //usdzData.addUsdz(url) // This task is just an asynchronous block of code.

I am developing visionOS application with Xcode 15.3 using visionPro 1.1 simulator. Using the simulator, I can only see 1 display which I assume is monoscopic only. I want to verify my application that it works fine with left and right eye (stereoscopic) in VR and MR modes. How to use the simulator displaying stereoscopic display?

I just upgraded my Macbook & Xcode installation, as we are required to target the latest iOS SDK later this month. I am now unable to compile our app as the iOS runtime is not installed by default. I have tried to download the missing runtime by clicking on "iOS 17.4 Not Installed - Get" in the top title bar. I think that the initial download may have been interrupted. Now, when I click "Get", I get a popup that suggests that I can't download the Runtime because the iOS Simulator is already installed. I'm guessing that Xcode is holding a reference to a non-existent installation somewhere, but I can't figure out how to get rid of it. I have tried completely uninstalling Xcode, and deleting /Library/Developer from both my personal directory and the system directory. I can't delete the iOS Simulator installation reference from Xcode directly either. When I try to, I get this error message: Unable to remove SimulatorRuntime Domain: com.apple.DVTFoundation Code: -1 User Info: { DVTErrorCreationDateKey = "2024-04-13 14:18:22 +0000"; } -- Unable to remove SimulatorRuntime Domain: com.apple.DVTFoundation Code: -1 -- Cannot stage disk image or bundle for delete: 87947E69-C049-4950-B663-C40C3BCAAFB2 Domain: com.apple.CoreSimulator.simdiskimaged.SimDiskImageError Code: 18 -- The file “87947E69-C049-4950-B663-C40C3BCAAFB2.dmg” doesn’t exist.

Hi, I'm a total beginner in programmation. I'm learning Unreal Engine by developing an iPhone game with the engine. I do not own an Apple Developper Subscription, so for testing my game on a real iPhone and/or on a simulator, I use the "quick launch" option in Unreal. Then, I open the Xcode Project created by the engine while attempting to quick launch directly on the device, and run the app from Xcode. Running it on my personal iPhone failed, so while trying to figure out why I've decided to try running it on the iOS simulator, and it failed. I got this message : Details : Simulator device failed to launch com.***.***.

I'm pretty sure that Rosetta is already installed on my system but I still tried to re-install it unsuccessfully. Here's what I get : softwareupdate --install-rosetta I have read and agree to the terms of the software license agreement.

I didn't find any way to perform a clean install of Rosetta online, only people saying that I shouldn't try to do anything with rosetta as it is supposed to be an automatic process or something. Maybe Rosetta wasn't the problem after all ? Or it is and I've just messed up the installation when I got it installed before ? (I installed GamePortToolkit previously, and I remember updating Rosetta while doing so). I tried to explain clearly the whole situation, don't hesitate to ask me any information if you need so. Thanks for your attention 🙏

When I try to list paired devices(like iphone with developer mode enabled and paired/connected with Xcode) using this command, I don't see it listed. xcrun simctl list pairs Can't see the paired devices in xcrun simctl list as well. I am on Sonoma 14.41 and the paired iphone is on ios17.2.1. Please advise.

Hello, I'm trying to test a call in the Simulator using CallKit. However, after the CXStartCallAction of CallKit is called, the CXEndCallAction is immediately invoked. I conducted the test using Xcode 15.2 and iOS 17.2 Simulator. When I searched because I couldn't test it on the Simulator, I found a similar issue on the following link. https://stackoverflow.com/questions/78291725/callkit-invokes-cxendcallaction-after-starting-the-call-resulting-in-hangup-on The person who asked the question in the link tested it with the previous version iOS 15.5 Simulator and it worked fine. Why isn't it working in the latest version? Is it a bug? Or has the policy been updated? If there are any documents available to check regarding this matter, please share them.

I am using Xcode Version 15.3 (15E204a) and different versions of Simulator runtimes (17.x, 16.x, 15.0) The app makes outgoing calls and can respond to incoming calls. After starting the call, ~2s pass before a hangup occurs. In the Console logs I see that CXEndCallAction was invoked by CallKit and the last suspicious log before invoking the CXEndCallAction is callservicesd Disconnecting call because there wont be a UI to host the call: <CSDProviderCall 0x107054300 type=PhoneNumber, value=sdsddsdds, stat=Sending tStat=0, model=<TUCallModel 0x103f661e0 hold=1 grp=1 ungrp=1> ... This used to work before, but since upgrading to Xcode 15 and iOS 17.x it happens constantly on simulator versions 17.x, and sometimes on 16.x, whereas I wasn't able to reproduce it on 15.0 version. Can someone help me understand why this happens and how to fix it? I provided some logs down below, and I don't see similar logs in the cases when the call is okay and CallKit doesn't hangup it. Also, this does not happen on real devices From the time CXStartCallAction is invoked until the CallKit invokes CXEndCallAction, these are some of the error or warn logs that appear: callservicesd -AVSystemController- +[AVSystemController sharedInstance]: Failed to allocate AVSystemController, numberOfAttempts=3 callservicesd [WARN] +[AVSystemController sharedAVSystemController] returned nil value callservicesd [WARN] Not allowing requested start call action because a call with same UUID already exists callWithUUID: (omitted) callservicesd Error while determining process action for callSource: (omitted) callservicesd Determined that callSource: <CXXPCCallSource 0x103d060a0, ...>, should process action: <CXStartCallAction 0x107232760 UUID=8D34853F-55DD-4DEC-97A7-551BFD27C924, error: Error Domain=com.apple.CallKit.error.requesttransaction Code=5 "(null)" callservicesd [0x103e417a0] invalidated after the last release of the connection object callservicesd [WARN] No paired device, so unable to send message UpdateCallContext callservicesd FaceTime caller ID (null) is not a valid outgoing relay caller ID callservicesd Attempting to find a valid outgoing caller ID in set of available outgoing caller IDs {( )} callservicesd Could not automatically select an outgoing caller ID; multiple telephone numbers are listed in the set of available outgoing caller IDs {( )} callservicesd Adding call <CSDProviderCall 0x107054300 ...> to dirty calls pool callservicesd Entitlement check: ... entitlementCapabilities={( "access-call-providers", "modify-calls", "access-call-capabilities", "access-calls" )}> lacks capability 'access-screen-calls' callservicesd [WARN] ... but no dynamic identifier could be found (1) or no handoff user info exists (1).

Everytime when iOS simulator is launched I het a lot of repeated "*** quit unexpectedly" alerts. Where "***" is a mix of "managedappdistributiond","healthappd", and "findmylocated" Even after the simulator is launched I still het random "*** quit unexpectedly" alerts. Very annoying because the alerts deactivates the active window This is on an MacBook Pro M3 Max,, Xcode 15.2, Sonoma 14.2.1, it also happens with Xcode 15.1 A co developer (MacBook Pro M1 Max,Xcode 15.2, Sonoma 14.2.1) does not have the issue Any idea how I can prevent this from happening? Update Every mentioned service crash happens in libswiftCore.dylib at 0x1929f3938 assertionFailure(:_:file:line:flags:) + 248

Hey. I'm a newbie in Xcode developing. I have just installed Xcode 10.2.1 on macOS 11.7.10 (20G1427) (my project cannot built on newer Xcode versions), and I guess that my copy of Xcode (or something related) is broken. Firstly, when Xcode running from Terminal, logs showing this: 2024-04-04 17:31:30.772 Xcode[1062:25499] Failed to load CoreSimulatorService. Access to simulator services will not be available. Error=Error Domain=NSPOSIXErrorDomain Code=61 "Connection refused" UserInfo={NSLocalizedDescription=CoreSimulator.framework was changed while the process was running. This is not a supported configuration and can occur if Xcode.app was updated while the process was running. Service name ((null)) does not match expected service name (com.apple.CoreSimulator.CoreSimulatorService).} 2024-04-04 17:31:30.773 Xcode[1062:36010] CoreSimulatorService connection became invalid. Simulator services will no longer be available. I tried to reinstall Xcode in /Applications, remove all Xcode-related folders, but nothing fixes. Secondly, I can't open Device Manager from Simulator. It says Not yet available. Please use simctl to manage devices. See rdar://problem/16642259. Screenshot: Please, who can help with this? (plz, sorry for my bad english :p)

if I get the string contents of a PDF and print to the console in Xcode . when run on simulator it’s fine but on device some words are missing. same PDF, same code. only difference is simulator and physical device. its only a word or two missing from the page. anyone have any experience or suggestions with PDFKit to explain why a string would be missing the odd word ?

Is it possible to mock the behavior of NWPathMonitor for a specific app? The scenario I want to support I've created an app called RocketSim, a developer tool for Xcode's Simulator. I've already created Airplane mode, which disables networking calls from URLSession from a specific bundle identifier app installed on the Simulator. Now, I want to support blocking NWPathMonitor as well. I believe the Simulator uses macOS's NWPathMonitor and does not use any specific HTTP request or similar to determine the reachability state. Is there a way I can make NWPathMonitor return unsatisfied when my 'airplane mode' is turned on? Potentially using a Network Extension?

Hello everyone, my app i'm developing doesn't show up in phone settings. By default, I install the application on the phone, then it starts, but I don't see it in the phone settings. I need it in the settings to enable the use of the camera, but I won't confirm it at the moment. Thanks everyone for your help

When building with Xcode 15 or greater to a simulator that is IOS 16 or lower I get a crash. Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: DYLD 4 Symbol missing Im not 100% sure it is an Xcode issue to be honest. It could be a react native issue. Everything works fine with Xcode 14.3.1 proven by my release builds through the pipeline working. Im really struggling to narrow down the issue. Any suggestions would be appreciated.

It seems cross-device passkey authentication isn't supported by the Simulator, is that right? I can't tell if it's the simulator not supporting it, or my app/server failing. My app, running in the Simulator, presents a QR code during sign-in flow. I scan that with my phone, and it just spins "connecting…". Can anyone confirm that the Simulator just doesn't support this? What are my options for testing this flow? I guess I need another device not sign in to my AppleID.

Hello, I am new to app development. I am trying to make an iMessage app. I created it and then added a SwiftUI view.

Can anyone tell me why all the simulators (see below) are not available in a project's iOS Simulator list? As an example, I've selected "iPhone 15 Pro" on the Simulators list, but it does not appear as available in the project list of simulators. Thanks for the assistance, Jake

Hello, I'm new to iOS development and I'm trying to take some screenshots of my app to submit to the App Store. I'm running Ventura 13.0.1 and XCode 14.1. So far I've used these simulators to take screenshots: 6.5 inch - iPhone 11 Pro Max 6.7 inch - iPhone 14 Pro Max 12.9 inch - iPad Pro 6th gen What I'm stuck on is getting the 5.5 inch screenshots, which are required for App Store submission. As far as I can tell from some online searching, the latest iPhone with that screen size was the 8 Plus. I've installed the oldest iOS simulator that XCode has listed (iOS 13.7), but it still won't let me run a simulator for the iPhone 8 Plus to get those screenshots. I don't have the physical device to take screenshots on. Does anyone know how to get the 5.5 inch screenshots without having to manually resize them?

I installed VisionPro's Simulator with Xcode last year, and now I want to uninstall it, but there is an xrOS1.0 disk in the disk image that cannot be erased. Later, I tried to erase the disk in MacOS recovery, but the display failed. I also tried to uninstall the xrOS1.0 disk, but I can't erase the xrOS1.0 disk. Every time I start up, a pop-up window is verifying xrOS1.0, which affects my normal use. I hope you can give me a solution. Thank you!
