I am having a crash with a Swift -> Objective-C interoperability under Xcode 14 / Swift 5.7 but only when Optimize for Speed is part of the build. There was no issue with this under Xcode 13.4.1 / Swift 5.6 under the same conditions. Typically, this compiler option is disabled for Debug builds so this was only detected once we provided release builds to beta users using Test Flight.  The interoperability is with using a proprietary, third-party framework. I am not privy to the Objective-C code that makes up the public API for this framework. As the framework had worked with Xcode 13.4.1 (with and without the speed optimization) and also works in Debug mode with Xcode 14.x (I have tried 14.1 as well) but crashes with the speed optimization turned on, I suspect the optimization may be at fault. But it is hard to say. I am hoping someone with better knowledge than I of this can guide me as to why this is happening…and only now. Here is an example of the code. Note: there are multiple instances of this same pattern in the API. There are vendor supplied structures (as well as NSArray as in this example) that cause similar failure. The vendor has supplied only Objective-C sample code and documentation.     func listItems() {         var availableItems: NSMutableArray? = NSMutableArray()         let result = itemSDK.getAvailableItemList(&availableItems)     // ...     } The header file provides: - (ITEM_RESULT) getAvailableItemList:(NSMutableArray**)getAvailableItemList; The derived Swift interface for this is: func getAvailableItemList(_ availableItemsList: AutoreleasingUnsafeMutablePointer<NSMutableArray?>!) -> ITEM_RESULT The crash occurs when calling the API and/or attempting to use the value associated with the AutoreleasingUnsafeMutablePointer. I have turned on all memory management diagnostics for the run phase of the scheme. When I do so, I see the following in the console when I get a fatal Thread 1: EXC_BREAKPOINT (code=1, subcode=0x1d66e8a88) presented in the caller to the listItems() method. *** -[__NSArrayM retain]: message sent to deallocated instance 0x28bd15200 My assumption is that this indicates the memory was released (aggressively?) and so this causes the crash. Again, only with the -O (Optimize for Speed) option is enabled. I have been able to code a potential solution to this issue. Maybe this should have been the solution for prior Swift versions…but I had no reason (as it had worked without issue up until Xcode 14).     func listItems() {         let itemsArray = NSMutableArray()          var availableItems: NSMutableArray? = itemsArray         let result = itemSDK.getAvailableItemList(&availableItems)     // ...     } This solution assigns the array to an immutable variable and then assigns that reference to an optional that is passed for the AutoreleasingUnsafeMutablePointer. My assumption is that adds an additional retain to keep the optimization from removing the memory for the array until the itemsArray is no longer referenced. I am reaching out to see if this is a known issue by others and/or expected (but new) behavior as I do not have much experience with AutoreleasingUnsafeMutablePointer. Also, if this is not a bug but is the new normal, is the potential solution the proper way to use the AutoreleasingUnsafeMutablePointer with Objective-C framework APIs? Or should I be doing something different? Thanks for any insight or pointers (even if unsafe).

Greetings, due to the current situation (Corona-Virus) I had to download Xcode, MS Visual Studio and Visual StudioCode on my personal MacBook Pro (2017; no Touch Bar). These applications were all asking for git (git-scm) and I have accepted. After some regrets I have decided to delete all applications again. I was able to delete Xcode, MS VS and VS Code but there was no program with the name git“, but hundreds of files with a big red „h“ on them, that I have never seen before. I used the function for a secured system restart and at the end I was reinstalling MacOS BigSur. Every time I logged in my entire display was black and my cursor in a neon blue I installed a new MacOS again and now everything seems to be fine (at least no black screen). I used some codes, I got from google, on my terminal (sudo rm -rf /usr/bin/git/), I am afraid that it has done more damage than it was helpful. Any idea how I can reverse the last 24 hours? Summary: Is Git already installed when I buy a new MacBook? If not, how can I delete all unnecessary files? Has „sudo rm -rf /usr/bin/git/„ changed anything? My terminal said that I was having Apple Git 128. After deleting XCodes there seems to be no git $ which git /usr/bin/git $ git --version xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun Sorry for all the questions, but I am totally unskilled when it is about using git. Kind Regards,

Hi team in the recent update IOS 16 , the lockscreen notification look has been changed,but even if we delete those messages the next day the same notification appears to be present in the lockscreen ,if we open the message it will be empty .

I've just fixed very strange bug / error/ undocumented feature on my Xcode conf. When I was running the latest Xcode 13.4.1 and highlight / autocompletion stopped working as I believe since macOS Monterey upgrade (before I ran Xcode 12) since I "fixed" some conf values by running defaults write com.apple.dt.Xcode some keys. Now I fixed It by deleting that edited config and re-running Xcode again and now it shows me autocompletion suggestions and follows headers when I press @@ defaults delete com.apple.dt.Xcode I just prepared this post with the ending: What should I do to make it possible to work? Appreciate for any help (Show live issues is turned on). Since I solved it I leave these words to let anyone who needs it to fix the issue with this mini tutorial. It somehow doesn't affect Swift code. Here's the stripped version of my old broken conf produced by defaults read com.apple.dt.Xcode: { BuildSystemScheduleInherentlyParallelCommandsExclusively = 1; CurrentAlertPreferencesSelection = "Xcode.AlertEvent.BuildStart"; "DTDKCrashLogSortDescriptors4.5" = ( { NSAscending = 0; NSKey = processName; NSSelector = "compare:"; }, { NSAscending = 1; NSKey = type; NSSelector = "compare:"; }, { NSAscending = 0; NSKey = dateTime; NSSelector = "compare:"; } ); DVTTextAutoSuggestCompletions = 1; DVTTextCompletionRecentCompletions = ( NSString ); DVTTextIndentCase = 0; DVTTextIndentTabWidth = 2; DVTTextIndentWidth = 2; DVTTextShowMinimap = 0; DVTTextSoloBraceIndentWidth = 2; DVTTextWrappedLinesIndentWidth = 2; IBAppliesAutoResizingRulesWhileResizing = 0; IBDesktopImageCacheVersionKey = "12.4-13F17a"; IBGlobalLastEditorDocumentClassName = IBStoryboardDocument; IBGlobalLastEditorTargetRuntime = "IBCocoaTouchFramework-fifteenAndLater"; IBPreferencesMigrated = 1; IBShowingMinimapStoryboard = 0; IBViewSizeInspectorPreferredRectTypeName = frame; IDEActivityLogShowsAllBuildSteps = 1; IDEActivityLogShowsAnalyzerResults = 1; IDEActivityLogShowsErrors = 1; IDEActivityLogShowsWarnings = 1; "IDEAnalyticsMetricsNotifications.AnalyticsMetricsNotificationsController.lastRefreshAttemptDate" = "2022-06-08 04:27:07 +0000"; IDEAppearance = 0; IDEBuildLocationStyle = Unique; IDECopyFilesToTargetGroup = 0; IDECreateGroupsForFolders = 0; IDEDebugSessionShowDisassemblyWhenDebugging = 0; IDEDisableGitSupportForNewProjects = 1; IDEDisableStateRestoration = 1; IDEDocSearchSelectedReferenceIdentifier = occ; IDEExtensionsBuiltPriorToXcode12 = ( ); IDEFileExtensionDisplayMode = 1; "IDEFileTemplateChooserAssistantSelectedTemplateName_iOS" = "Source/Header File"; "IDEFileTemplateChooserAssistantSelectedTemplateName_macOS" = "Source/Header File"; IDEFileTemplateChooserAssistantSelectedTemplateSection = "com.apple.platform.macosx"; IDEHasConvertedXcode3BuildPrefs = 1; IDEIndexDisable = 1; IDEIndexShowLog = 0; IDEKeyBindingCurrentPreferenceSet = "Default.idekeybindings"; IDEKeyBindingExcludedPreferenceSet = ( Default ); IDELastBreakpointActionClassName = IDESoundBreakpointAction; IDELogNavigatorGroupByKey = 0; IDEMaxParallelTestingWorkersMac = 0; IDEOpenQuicklyPreferSwiftGeneratedInterface = 0; "IDEOpenQuicklyWindowController.width" = 454; IDEProductsViewControllerSourceListSplitPosition = 215; IDEProfileActionSelectedTab = Info; IDEProvisioningTeamManagerLastSelectedTeamID = XXXXXXXXXX; IDEProvisioningTeams = { "my@email.com" = ( { isFreeProvisioningTeam = 1; teamID = XXXXXXXXXX; teamName = "Larry Moore (Personal Team)"; teamType = "Personal Team"; } ); }; IDEShowPrebuildLogs = 0; IDESoundBreakpointActionDefaultNameKey = Pop; IDESourceControlPreferencesVersion = 201; IDESuppressStandardArchitecturesUpgrade = 0; IDESuppressStopExecutionWarning = 1; IDESuppressStopExecutionWarningTarget = "IDESuppressStopExecutionWarningTargetValue_Stop"; IDESwiftPackageAdditionAssistantRecentlyUsedPackages = ( ); IDESwiftPackageCollectionsAddedDefaultCollectionsDVTToolsVersion = "Xcode 13.3.1"; IDETestActionSelectedTab = Info; IDETouchBarSimulatorIsVisible = 0; IDEUserWantsToEnableDeveloperSystemPolicyMode = 0; LastProcessNameAttachedTo = Riot; NSColorPanelMode = 1; NSColorPickerPreferredRGBEntryMode = 2; NSColorPickerSlidersDefaults = 1; NSNavPanelExpandedStateForSaveMode = 1; PBXNumberOfParallelBuildSubtasks = 10; PMPrintingExpandedStateForPrint2 = 0; PegasusMultipleCursorsEnabled = 1; ShowBuildOperationDuration = 1; Xcode3BuildSettingsEditorDisplayMode = 0; Xcode3BuildSettingsEditorMode = 0; Xcode3ProjectEditorSourceListVisible = 1; "Xcode3ProjectTemplateChooserAssistantSelectedTemplateName_iOS" = "Application/App"; "Xcode3ProjectTemplateChooserAssistantSelectedTemplateName_macOS" = "Application/App"; Xcode3ProjectTemplateChooserAssistantSelectedTemplateSection = "com.apple.platform.iphoneos"; "Xcode3TargetTemplateChooserAssistantSelectedTemplateName_iOS" = "Application/App"; "Xcode3TargetTemplateChooserAssistantSelectedTemplateName_macOS" = "Application/Command Line Tool"; Xcode3TargetTemplateChooserAssistantSelectedTemplateSection = "com.apple.platform.macosx"; } The only suspicious key is DVTTextAutoSuggestCompletions = 1; in this old config that might have stopped autocompletion.

Hi I'm finding it really difficult to integrate this tool in my Xcode project. The Fyber SKAdNetwork ID auto-updater is a tool for publishers to integrate into their build system and manage SKAdnetwork IDs into their Info.plist with each build job automatically. This will allow them to keep the Info.plist file up to date, even if some partners make changes to their IDs. Here's the link to the instructions: https://developer.fyber.com/hc/en-us/articles/360015298038-SKAdNetwork-ID-Auto-Updater I have installed the tool using Terminal but the rest is very confusing to me as I am not very familiar with some of the instructions/commands I'm being asked to do. Any help would be greatly appreciated - thank you so much in advance :) Ermes

Hello. I have developed an app: Kedeo.es: https://apps.apple.com/us/app/kedeo-es/id1609942690 Use external libraries to connect to Google Firebase Auth and Notifications. Also use Storekit for in-app purchase. It works perfectly, and it has also passed the tests and is published in the store, however, my client says that there are between 20% and 40% of users who are automatically closed just by opening. Does anyone else have this bug? It doesn't happen to me, and that's why I can't get any log to know more about the problem. If anyone can help I'd appreciate it. Greetings.

Is it normal for an app to try and wake my phone up 45,000 times over less than 300 seconds

Following the page MallocDebug After Enable Malloc Scribble, free buffer will be set to 0x55, malloc buffer will be set to 0xAA. would I change 0x55 and 0xAA to another value ? e.g 0xFF ?

Just yesterday a new app that is not searchable or on my phone started showing 100% usage, advisors.technologyadvise.com any insight as to what this could be?
