After submitting my app for review, I received a rejection on account of it crashing in MacOS 12.4 environment. The Objective-C app was developed in MacOS 12.4 and the app runs OK in Xcode and as a standalone executable. The crash log shows the exception type as SIGABRT and documentation. indicates that the crash may arise from an uncaught exception. Part of the crash log is shown below. How can I find out where the problem is occurring in my code?

I have downloaded an Objective-C Project CocoaSlideshow which I have modified, built, and run successfully in XCode 12.3 running on Catalina (10.15.7) but I cannot display the interface in XCode. I have created an archive and generated a .dmg file. There is no Main.storyboard file in the project. There is a message Unable to Load revisions at the bottom of the centre and right-hand panels. The Editor menu option does not include the option to display the Assistant Editor. How can I display the interface in this project?

When viewing total downloads for an App in App Store Connect App Analytics, the option to filter Total Downloads by version is greyed out when clicking Add Filter even though the app has had a version change 1 week ago as shown in the App Store Version history. The version option is greyed out when running App Store Connect from Windows (using Firefox) and from a Mac (using Safari)

I am trying to create a file from a text string in a web server in a folder C:\inetpub\wwwroot\AlekaConsulting\AlekaConsulting\License using IIS 10.0.14393.0 on a Windows Server 2016 environment using the following Objective-C code on macOS Catalina, but no file is created and the returnString variable contains the error message 405 - HTTP verb used to access this page is not allowed. The page you are looking for cannot be displayed because an invalid method (HTTP verb) was used to attempt access. The same error appears if I use PUT rather than POST as HTTPmethod. No verbs are listed in the Request Filtering tab of IIS Manager, which means no verbs are blocked. webDav is not installed as a server feature. Content can be successfully read from files in the specified folder. Is the error connected with the URL being accessed via https?

I have a Swift 5 app that I would like to test on an iPad simulator but the only iPad simulator available is iPad (8th generation). I have a 5th generation iPad which is running iPadOS 15.4 which is presumably capable of running a Swift 5 app but its simulator does not appear in the list of possible iOS simulators.

How can I create a simulator for an iPhone 6 (runninf iOS12.4) in Xcode 12.3? Entries in the Simulators list shown in Preferences->Components are all greyed out. The entries go up to iOS14.2. If I try to create a new Simulator by clicking + in Window->Devices and Simulators, Simulators tab, the only OS version available in the dropdown is iOS 14.3. If I try to download more Simulator runtimes I see the greyed out list shown in Preferences->Components.

I have a Swift 5 iOS project in XCode 13.4 containing a View Controller with 5 UI PickerView controls, each with height set to 74 using Interface Builder. The view controller is shown as a popover. When I run the project using an iOS 15.5 simulator, the UIPickerViews appear as designed. When I use an iOS 16.0 simulator I see 5 console messages of the form [UIPickerView setFrame:]: invalid size {204,74} pinned to {204,162} and the UIPickerViews are much larger and their arrangement is not as designed. Has iOS 16.0 returned to only allowing a small number of UIPickerView heights rather than allowing an arbitrary height?

I have an Objective C project for MacOS in XCode 12.3 running on Catalina. A preferences screen shown at run time has started displaying controls in inverted vertical order, as though the Y origin is at the top (as it is for iOS) rather than the bottom (as it is for MacOS). In design view the ordering is correct. How can I fix this problem?

I'm getting the error "Cannot create Swift scratch context (couldn't create a ClangImporter)" when running a Swift project in XCode 12.3 on Catalina when I try to use the debugger. There is a resolution of this problem described at https://forums.raywenderlich.com/t/entering-debugger-in-swift-project-couldnt-create-a-clangimporter/130829 but I don't understand the fix of "removing zsh customisations in dotfiles". Can anyone explain what the files to change are and how they have to be changed? (I'm new to Mac development)

Where is the data for NSUserDefaults standardUserDefaults stored? I would like to edit stored values as is possible in the Windows Registry. I am using XCode 12.3 on Catalina. Finder search does not show any non-source code file on the machine which contains the persisted values.

I am developing an app to run on iOS 12.4 or newer using Xcode 12.3 on MacOS Catalina. On my screens I have a number of navigation bar buttons which have a system icon specified as well as text in Interface Builder. When running on an iOS 14.3 simulator, the bar button icons appear but on an iOS 12.4 simulator (and an iOS 12.4 device) the icons do not appear and only text is shown. The buttons still work OK on iOS12.4. How can I make system icons appear in Navigation bar button items in Xcode 12.4?

An application toolbar in an XIB file created in XCode 12.3 on MacOS Catalina from an Objective-C project appears as below But in XCode 13.4 it appears as below (the rotate icon has been changed) When the application is run under Xcode 13.4 or on MacOS Monterey the application toolbar appears as below How can I make the toolbar appear as it does in Xcode 12.4 when running on Monterey or using Xcode 13.4?

I would like my sandboxed MacOS app to save a log file in a sub-folder of the user's Documents folder, but the app cannot create the sub-folder, create a file or write to an existing file even though I have given the app full disk access via System Preferences-> Privacy. How can I do this?

I'm trying to sign into a Sandbox account which is visible in App Store Connect from an iPhone 6 running iOS 12.5.5. After submitting Sandbox account or Apple ID credentials, a gear wheel appears but when it disappears the Sign In prompt reappears. If I enter invalid credentials, immediate feedback they they are invalid is shown.

I have an Objective-C MacOS app originally developed in Catalina on a 2012 Macbook Pro and recently ported to a 2019 MacBook Pro running Monterey and using Xcode 13.4 in response the App Store no longer accepting apps developed in Xcode 12, which is the newest version supported by Catalina. The app is targeting MacOS 12.0 (Catalina). The app builds and runs OK on Monterey, but when run on Catalina it crashes and the crash log error reason (NSCFConstantString stringByAppendingString:]: nil argument) is incorrect, as diagnosed by a series of log statements. The statement on which it fails is calling setSelectionIndex on an ImagesController class, which uses the NSArrayController interface.
