Set the build destination to Mac Catalyst, and the build will run properly. I filed a feedback (FB13904284) and shared this with Apple engineers during a WWDC24 lab session.

@ps3zocker thanks for the detailed overview of the problem. I filed my own feedback (FB13902858) and referenced your blog post and feedback ids. Let's hope Apple gives us the option to opt-out of the new tab view behavior in iPadOS 18.

Yes, I added the user-defined setting to my target's build settings, re-built the app, and the intents now work on iPadOS 16.

The release notes of Xcode 15.3 has another workaround: https://developer.apple.com/documentation/xcode-release-notes/xcode-15_3-release-notes AppIntents may fail to execute when the target’s minimum deployment target is iOS 15.0 or earlier (123798206) (FB13664020) Workaround: Add the ENABLE_APPINTENTS_DEPLOYMENT_AWARE_PROCESSING=NO build flag to your target(s)

I've written a blog post and video detailing this problem and the workaround: https://youtu.be/OMqEhcguevM https://labs.mixeffect.app/article/2024/05/psa-shortcut-actions-broken-xcode-15-4/

I'm seeing the same problem. Rebuild your project using Xcode 15.2, and AppIntents will work again. I filed a feedback with Apple, and I suggest you do the same. Reference this: FB13812174

Did you ever find a solution to the crashing bug? I'm seeing this to in the AVCam sample app when run on the Mac.

Getting this problem on Xcode 12 or Xcode 13 on an iPad mini running the GM of iOS 15.

Perhaps you're using ulimit -v dyld4 config: DYLD_LIBRARY_PATH=/usr/lib/system/introspection DYLD_INSERT_LIBRARIES=@executable_path/Frameworks/libclang_rt.asan_ios_dynamic.dylib:/Developer/usr/lib/libBacktraceRecording.dylib:/Developer/usr/lib/libMainThreadChecker.dylib:/Developer/Library/PrivateFrameworks/DTDDISupport.framework/libViewDebuggerSupport.dylib

My project is structured a little differently in that I have a Workspace in which there are two framework projects underneath the main project. See screenshot: When I click on the Intents.intendefinition file and try to change its settings, they are changed for both entries (since the top-level one is a reference to the one in the embedded framework). If I remove the reference in the main project, the actions don't appear anymore in Shortcuts.
