Hi there, Recently we have been seeing thread_policy_set(1) returned 46 flooding our log output. We tracked down that the flood of this is coming from a separate library whom we've contacted. They mentioned that this is a Apple internal message that comes up in the library's deadlock detector. The proposed solution was to use OS_ACTIVITY_MODE env var to hide the logs as suggested from the post on StackOverflow.. I tried all suggestions from that StackOverflow post, which were able to hide other system logs generated from Apple but it specifically did not hide the thread_policy_set(1) returned 46 What I am hoping to understand is: Why does this message come up? I see that the documentation for this on Apple's docs is very limited. Is this message's visibility controllable via a separate variable in project settings outside of modifying settings for all logs? As a last resort, how can I disable only this log message? Thank you!

Hi there, It seems from the documentation That Guard malloc is only working on simulators. Is this still relevant? Same question for other tools like: Zombies Address Sanitizer Many thanks

Hi, I am getting below error when trying to upload archive from xcode : - Missing 64-bit support. iOS apps submitted to the App Store must include 64-bit support and be built with the iOS 8 SDK or later. We recommend using the default "Standard Architectures" build setting for "Architectures" in Xcode, to build a single binary with both 32-bit and 64-bit support. With error code STATE_ERROR.VALIDATION_ERROR.90086 for id 75ffbe1b-dbc7-4213-82a8-a520b19cf690 I have already set arm64 under Build settings for my project and even my ios SDK version is 11.0 My Xcode version is 13. Stuck in this issue since past one week. Any help will be highly appreciated

I am having an image assets used for loading the background image in my iOS application. The image assets contains background images that provides support for 2x, 3x, 2x Retina 4, 2x Retina HD 4.7", 3x iPhone X/iPhone Xs, 3x iPhone Xs Max and 2x iPhone XR. When i run my iOS application using XCode 13.3 on iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max then the background image is not loading instead a white colour background is getting displayed. When i try to run the iOS application using XCode 13.3 on iPhone 12 or any other Simulator devices (other than iPhone 11 family) then the background image is getting loaded perfectly. Can you please suggest on how to fix the background image loading issue getting occurred only in iPhone 11 having iOS 15.4 version?

I received the following warning: [TableView] Warning once only: UITableView was told to layout its visible cells and other contents without being in the view hierarchy (the table view or one of its superviews has not been added to a window). This may cause bugs by forcing views inside the table view to load and perform layout without accurate information (e.g. table view bounds, trait collection, layout margins, safe area insets, etc), and will also cause unnecessary performance overhead due to extra layout passes. Make a symbolic breakpoint at UITableViewAlertForLayoutOutsideViewHierarchy to catch this in the debugger and see what caused this to occur, so you can avoid this action altogether if possible, or defer it until the table view has been added to a window. I am getting the warning during debugging and my table fully loads with data at that point, but when I change the scheme to release to put into TestFlight, my app crashes as soon as the tableView starts to load the data. Does anyone know how to prevent a table from executing before data has been fully loaded? I have tableView.reloadData() occurring in the ViewDidLoad section.

Hello! I'm working on a new app, and DYLD_PRINT_STATISTICS=1 is not working - i.e., not producing any output. Build platform: MacBook Pro (15-inch, 2018) macOS Monterey, 12.0 beta 6 (21A5506j) Xcode 13.0 beta 5 (13A5212g) Test device: iPad 8th generation iPadOS 15.0 beta 8 (19A5340a) I'm setting it as usual in Product -> Scheme -> Edit Scheme, then going to "Run" tab on the left and choosing "Arguments" on the top. In that screen I enter "DYLD_PRINT_STATISTICS" for Name and "YES" for Value. Nothing prints. I also tried: Using "1" for Value instead of "YES" Entering "DYLD_PRINT_STATISTICS=YES" as Name and leaving Value blank Entering "DYLD_PRINT_STATISTICS=1" as Name and leaving Value blank Every combination of the above, but as command-line arguments instead of environment variables. Also, I tried "DYLD_PRINT_APIS" as Name and "YES" as Value, and that works normally. What's going on here? Is it something with the all-SwiftUI lifecycle? An issue with the beta macOS/Xcode/iPadOS? Thanks!

Is it possible to get Thread Sanitizer to work when debugging an audio unit extension? For me XCode just waits forever after the host app is launched and before the AU debugging session starts. (Host and AU are part of the same project)

Hello everyone! My app is getting a crash in the tableView(_:trailingSwipeActionsConfigurationForRowAt:) function. Apparently, the app is crashing when trying to get the indexPath.section value. I am attaching the crash log. This is not reproducible for me. I have the hunch that this might be related to some accessibility feature, but I have not been able to corroborate it yet. I am not sure how to solve this issue or how to move forward since I still don't know what is causing the app. Any advice or guidance is really appreciated. Thank you!

My App had no such warnings before updating to 13.3, but now it claims I'm updating from a background thread. A simple print will make these warnings stop, so something is wrong:  @MainActor private func runOnMain(_ action: @escaping () async -> ()) async {         //print("", terminator: "")         await action()     } simply uncommenting that print() makes all the warnings go away, so I think 13.3 has an issue here... Is anyone else seeing this?

I receive random crashes during an ARWorldTrackingConfiguration Session with this message: Assert: in line 508 dyld4 config: DYLD_LIBRARY_PATH=/usr/lib/system/introspection DYLD_INSERT_LIBRARIES=/Developer/usr/lib/libBacktraceRecording.dylib:/Developer/usr/lib/libMainThreadChecker.dylib:/Developer/Library/PrivateFrameworks/DTDDISupport.framework/libViewDebuggerSupport.dylib:/usr/lib/libMTLCapture.dylib (lldb)  What shall I do? There is no reliable way to reproduce this error. It is thrown randomly - sometimes a few seconds after the completion of the relocalization process, but sometimes not at all.

I have uploaded an app twice now to have it rejected due to it crashing upon loading. I have tested and tried this on simulators it works fine, I also have this already working for the android store. Been trying to work this out for a while now but not sure how to fix this moving forwards. The crash log is as follows: Crash File. Any help would be amazing. Many Thanks,

Hi everyone, Let me prefix this question by saying that I am not an iOS developer... so be gentle :-) A friend has an older codebase (written in xCode 11) that was abandoned by the developers that were working on it. He needed someone to fix Firebase logging (which I did) and everything was fine until recently. Now upon moving to any xCode > 12 there is a runtime error deep in the library code used throughout the app. The error (slightly generalized) is as follows: Could not cast value of type '() -> MyApp.TabBarFC' (0x111eda8a0) to '() -> LibraryKit.LibraryFC' (0x111eda8c0). the respective classes are declared as follows... in app code: class TabBarFC: LibraryTabBarFC { in library code: open class LibraryTabBarFC: LibraryFC { The line it specifically crashes on is in a flow controller (FC) repository in the library code where you can see an attempt to cast the app parameter to the class LibraryFC: var factories: [LibraryKit.Id.FC : () -> (LibraryFC)] = [:] open func register<FC: LibraryFC>(factory: @escaping () -> (FC), id: LibraryKit.Id.FC) { factories[id] = factory as! () -> (LibraryFC) } This code worked in xCode 11. It does not work now. If anyone could tell me if there is an obvious fix (it could be trivial), it would certainly be faster than giving the entire codebase to someone else or me reading documentation for a few nights. Thanks!

After upload and download my project into a new version of Xcode, I got this message "Failed to install the requested application" Does anyone knows how to fix this issue?
