Immediate crash of Apple Watch simulator when typing a key
I get a crash in Apple Watch simulator (Series 9 45mm 18.0) as soon as the app launch if I type anything on external keyboard (just hitting command key for instance to capture a screenshot). Same crash on series 7 (45mm, OS 18.1) But app works normally when I use mouse to interact with the app on simulator. App does not crash on real device (Watch 4 OS 10.4.1). Nor does it crash on Series 6 simulator (44 mm OS 17.4). Here are the log I could collect (apparently, they contain sensitive language !!! so I attach as a file.: Attached logs

A few questions about allowed-os-versions and os-version in Distribution Definition files
In the archived documentation for Distribution Definition files (https://developer.apple.com/library/archive/documentation/DeveloperTools/Reference/DistributionDefinitionRef/Chapters/Distribution_XML_Ref.html), the allowed-os-versions and os-version element are partially documented. I have a few questions about these elements: allowed-os-versions The documentation states: Availability: Available in OS X v10.6.6 and later. Has this element always worked correctly in the past? I'm asking because it does not seem to work correctly on OS X v10.14 for the min attribute of a sub os-version element. os-version The documentation states: This element is designed for you to use a specific OS version number for the min attribute, and a major OS version number for the before attribute. The expectation is that you will know an exact minimum version but not an exact major version. This keeps you from having to guess the last minor revision before the next major revision, as you would have to do if the before attribute were inclusive. This is quite confusing because the documentation never explicitly says what a specific or major OS version number is. Is specific major.minor.patch or major.minor? What is major? major or major.minor? As the documentation was created at a time where the OS version scheme was: 10.minor.patch (and minor was actually the major) and we are now in an era where the OS version is major.minor.path, this is even more confusing. I would also be curious to know what the major version is officially supposed to be for macOS Tahoe in this case. 16 or 26? Generally speaking, this documentation is missing examples for a lot of the elements. Also why is there a tag for InstallerJS and not one for Installation in the Developer Forums?

Errors after importing plugins on other machines via source control
We are trying to setup Apple Unity Plugins, in out project we have a handful of developers who contribute to the project via git. When building and importing plugins via tarball (as instructed in the Github repo) the package clearly points to local path, so once pushed all members encounter the error: An error occurred while resolving packages: Project has invalid dependencies: com.apple.unityplugin.accessibility: Tarball package [com.apple.unityplugin.accessibility] cannot be found at path ..... When trying to actually move content to the package folder (same way as any other unity plugins is setup) and add it as "embedded", it works fine on local machine, but team members will get a few of errors: [Apple Unity Plug-ins] No Apple native plug-in libraries found. DLLNotFoundException: AppleCoreNativeMac assembly ... No Apple Native plug-in libraries found. Moreover AppleCoreNativeMac.bundle is flag as not verified and deleted by macOS. What is the right way to setup unity plugins in a project used by multiple members via sourcetree ?

MetricKit Metric Payload Split
In MetricKit, a metric payload comes in with a time range which usually means it contains multiple launches/sessions. How can we relate things that will change between launches or sessions such as pid and lowPowerModeEnabled from the metadata. Will there be multiple payloads for each unique value or is there some other way to use this?

When creating a nested framework, most but not all symbols found
I've got an app where I want to split its Model code into a framework (.xcframework and .framework for debugging) so that it can be used by more than one app. The code has dependencies on 3rd party code, which are installed via pods. During the conversion process I keep running into the same issue which manifests with all the 3rd party code - which is that the majority of its api can be used (something like 80-90%) but for the remainder there is a linker error at runtime showing undefined symbols. I have this problem with CocoaLumberjack,RealmSwift, PhoneNumberKit and more. Its very quick and easy to reproduce the issue with a minimal framework and minimal app, below I'll describe how a minimal setup using CocoaLumberjack reproduces the issue: From scratch, I use Xcode to create a framework project, run pod init, then modify the pod file to be: platform :ios, '16.0' workspace 'TheFramework' project 'TheFramework' target 'TheFramework' do use_frameworks! pod 'CocoaLumberjack/Swift', '3.8.5' end post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '16.0' config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES' end end end Then I add source code: import Foundation import CocoaLumberjack public class AClassInTheFramework { public class func aMethod() { let consoleLogger = DDOSLogger.sharedInstance DDLog.add(consoleLogger, with: .debug) DDLogDebug("Some logging") } } Within the Xcode project, Build Libraries for Distribution is set to Yes, I also add that line to the pod file in case CocoaLumberjack isn't set similarly. In the Framework's Xcode General section, Frameworks and Libraries contains Pods_TheFramework.framework set to Do Not Embed. In the Build Phases section, in the Link Binary with Libraries section, Pods_TheFramework.framework is set to required. Next I create an Xcode app template, run pod install, and edit the app pod file to be: platform :ios, '16.0' workspace 'AppUsingFramework' project 'AppUsingFramework' target 'AppUsingFramework' do use_frameworks! pod 'CocoaLumberjack/Swift', '3.8.5' end post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '16.0' end end end I build the framework, and drag and drop it into the app. I add the following code to the app's delegate: import TheFramework ... AClassInTheFramework.aMethod() The App's target has the following linkage settings: When I build and run the app, there is the following error: If I change the source code in the framework to this: public class AClassInTheFramework { public class func aMethod() { let consoleLogger = DDOSLogger.sharedInstance DDLog.add(consoleLogger, with: .debug) // DDLogDebug("Some logging") } } Then there is no error and the code runs successfully. This illustrates the problem I've encountered with all the nested frameworks - in this particular case calls to DDLog.add() don't result in an error but calls to DDlogDebug() do, and that has been mirrored with other nested frameworks (for example with Realm, opening a database, adding, finding,retrieving an item all works without a problem, however attempting to use Realm's Results<> API results in a similar symbol not found error). Additionally note that the identical CocoaLumberjack code can run fine when used directly from within the app, i.e., if I add the following code to the app: import CocoaLumberjack func useCocoaLumberjackDirectlyFromWithinApp() { let consoleLogger = DDOSLogger.sharedInstance DDLog.add(consoleLogger, with: .debug) DDLogDebug("Some logging") } useCocoaLumberjackDirectlyFromWithinApp() Then it runs, i.e. DDLogDebug() can be successfully called from within the app, its only when its called via the framework that the error occurs. Why might I be encountering these issues? I'd have thought either I'd be able to use 100% of the nested framework's public api, or 0% of it (is something is not configured correct), not ~80% which is what I am encountering. Any ideas? TIA

lldb: argument starting with hash disappears.
Here's a simple C++ program that echoes its arguments... #include <stdio.h> int main(int argc, char* argv[]) { for (int i=0; i<argc; ++i) printf("%d %s\n", i, argv[i]); } This works as expected... > ./test arg1 #arg2 arg3 0 ./test 1 arg1 2 #arg2 3 arg3 Running under lldb gives this... > lldb ./test arg1 #arg2 arg3 (lldb) target create "./test" Current executable set to '/Users/richard/Work/test' (arm64). (lldb) settings set -- target.run-args "arg1" "#arg2" "arg3" (lldb) run Process 6138 launched: '/Users/richard/Work/test' (arm64) 0 /Users/richard/Work/test 1 arg1 Process 6138 exited with status = 0 (0x00000000) I get the same if I quote the arguments, or if I add them to the run line. Stepping into main() we see the argv and args values are as though we only had the first argument. If I quote the second argument and add an initial space " #arg1" then it works. I first saw this on an M1 running Sequoia 13.1. It am now on OS 13.3. lldb --version lldb-1600.0.39.109 Apple Swift version 6.0.3 (swiftlang-6.0.3.1.10 clang-1600.0.30.1)

libclang_rt.profile_driverkit.a' not found
Hi guys! I have gone through an absolute nightmare, trying to solve the issue that I am about to tell you about. As the title says, I am getting the error: Library '/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/17/lib/darwin/libclang_rt.profile_driverkit.a' not found I trimmed off part of that directory as I did not want to reveal that information about my computer. From what I can tell, the file in question is no longer even a part of Xcode. I have searched, it is not on my computer anywhere. I have also downloaded older versions of Xcode to search with it. None of them have it. I have literally tried everything under the Son to solve this issue. I have been stuck on it for two days. I have even resorted to doing something I hate, which is asking for ChatGPT to assist me with solving the issue. No help there. I am at my wits end. So I am coming to you guys, have you seen this error? Any ideas at all? The odds are pretty good whatever you recommend I have probably already tried 200 times over. But I am still open to hearing anything. Have any of you had this error? Any ideas? I am on the latest version of macOS. The project is for a macOS app. M4 Mac mini. Any additional information I can provide, that will be helpful? At this point, I am leaning more towards this being a bug with Xcode than anything.

Cannot compile a simple C++ program on Mac OS
I'm trying to compile a simple hello world C++ program on my MacBook Pro. I have a M3 Pro (Nov 2023) running Sequoia 15.6.

macOS 15.6: Opened package is not the same at install time
I've created an installation package and it is failing to install on macOS 15.6. The package is, I believe, properly notarized, since it will install correctly on other macOS versions, including 15.5 The only clue I have is the output from installer: installer[8015] : Opened package is not the same at install time installer[8015] : Unable to use PK session due to incompatible packages. Terminating. installer[8015] : Install failed: The Installer could not install the software because there was no software found to install. The installer consists of a a single "component" package, and the outer "product" package. The component package is present, and I can successfully run installer manually to install it, so I don't think the component package is corrupt. Has anyone else encountered this? Are there any tools available to help me diagnose the issue? The logging is not helpful.

The Xcode project keeps crashing on launch
Hello, I need a little bit of help. My game keeps crashing on launch no matter what I do. I’ve tried running it in Xcode on my Mac, on my iPhone, and through TestFlight, but I get the same result every time. I’ve tried everything I could find on the internet, and nothing worked. Asking here is my last resort because I’m completely stuck. The game runs fine in Unity, but not so much in Xcode. Can someone help me figure out what I’m doing wrong?Any help would be greatly appreciated. Here is the error log I found by connecting my iPhone to my Mac. To view the logs, I used the Console in the Devices and Simulators section of Xcode. ➤ SecKeyVerifySignature failed: Error Domain=NSOSStatusErrorDomain Code=-50 "rsa_pub_crypt failed" [10:27:36.034791+0200] kernel ➤ Sandbox: [App] deny(1) sysctl-read kern.bootargs [10:27:36.043389+0200] SpringBoard ➤ Live host view super view[(null)] not matching container view ➤ Frame not updated [10:27:36.050473+0200] backboardd ➤ Cycle detected [10:27:36.100799+0200] SpringBoard ➤ Live host view super view[(null)] not matching container view [10:27:36.538361+0200] akd ➤ Error fetching keychain item - Error Domain=NSOSStatusErrorDomain Code=-25300 "no matching items found" [10:27:36.545734+0200] akd ➤ Failed to set last known MID with error (Error Domain=NSOSStatusErrorDomain Code=-25300) [10:27:36.603384+0200] rtcreportingd ➤ Gap in hierarchy: [10:27:36.604536+0200] cloudd ➤ TCP input flags=[R.] state=LAST_ACK [10:27:36.613317+0200] cloudd ➤ TCP input flags=[R] state=CLOSED [10:27:36.648449+0200] kernel ➤ 1 duplicate report for Sandbox: [App] deny(1) sysctl-read kern.bootargs [10:27:36.648484+0200] kernel ➤ Sandbox: [App] deny(1) file-test-existence /private/var/Managed Preferences/mobile/com.apple.CoreMotion.plist [10:27:36.900275+0200] CommCenter ➤ Client is not entitled for request [10:27:37.131555+0200] storekitd ➤ AMSURLSession: Session decoder failed.

Unlocking hidden "Developer mode" option on Ipad (without Mac or Xcode)
Hello, I have an iphone but not an ipad Actually a relative has an iPad. The problem I encoutered was when i was testing an app that I had built prior (so I had the ipa file) but no acces to Xcode. The thing is when I wanted to test it on my iphone, everything WENT SMOOTH and ok. When I tried on iPAD, I encounteed the problem I could not unlock the hidden "developer mode" option in any way, I tried so many things, checked and rechecked, the option was and stayed hidden, I could not activate it. Therefore I could not test the app. In the apple store I was required to give a screenshot for iPAD but that failed. because I could not produce ANY, since I could not run my app on iPAD. I actually have no idea how I activated the ability to turn on the developer mode on my iphone, it was just there and I activated it perhaps because I had added the email of my iphone to the developer account somehow? somehwere? But for iPAD I just could not find a way to do it, don't know if adding it somewhere could trigger something on the ipad to allow it to show the developer mode option so I can activate it finally? Anyway, I tried things I read on internet, methods that mention how to activate the developer mode ability on an ios devide though WINDOWS, there were 2 but one I did not trust much, and even I think i tried it and in the end it did not work for some incompatibility making that method obsolete or something? the other I am not sure but probably same idea. I would like to know, how to activate the ABILITY to SHOW the option to activate the developer mode on iPAD (or any other device but for now I am focuson on iPad) please, and without using macbook or xcode!? Could Apple or anyone offer some guidance? That would help a fellow developer. Thank you. Ps. No I cant get the mac or xcode for now (but hopefully in a far future, but for now I can't). Thanks

Unable to Test Xamarin App with iOS 26 Simulators in Visual Studio
Hello, I’m trying to test a Xamarin.iOS application using the iOS 26 simulators in Mac Visual Studio, but I’m encountering an issue where the simulators are not appearing or accessible from Visual Studio. Details: macOS version: 15.6 (24G84) Xcode version: 26 Beta 5 Visual Studio version: 17.6.0.80 Xamarin.iOS version: Xamarin.Forms (Version: 4.6.0.1180) using XAML for cross-platform support (iOS/Android) The problem started after updating to iOS 26 SDK. I am unable to select or run the app on any iOS 26 simulator from Visual Studio. Has anyone faced a similar issue? Is there any configuration or workaround to enable iOS 26 simulators for Xamarin projects? Thanks in advance for your help.

How to Obtain License File for Main Camera Access Entitlement in visionOS (Email Was Deactivated During Approval)
Hi everyone, I'm developing a visionOS application using Unity with an enterprise developer account. I applied for the Main Camera Access entitlement, but at the time of submission, the email address associated with my Apple ID was deactivated, so I couldn’t receive any email communication from Apple. Later, I updated the email address for my Apple ID. Now, in the Apple Developer portal under Identifiers, I can see that my app has been granted Main Camera Access, and I can also add the corresponding capability in Xcode. However, according to Apple’s documentation(https://developer.apple.com/documentation/visionos/building-spatial-experiences-for-business-apps-with-enterprise-apis): “To use entitlements, you need to include both the entitlement file and a corresponding license file in your app. After Apple approves your app for one or more entitlements, you receive a license file, along with additional instructions.” I never received this license file, possibly due to the deactivated email. I don't know where to find it or how to retrieve it now. What exactly is this license file? If it was originally sent to an unreachable email, how can I request it again or get it resent? Where in the Apple Developer portal (or elsewhere) can I access or download this file? Any help or guidance would be greatly appreciated! Thanks in advance.
