Is anyone else seeing their apps crash on iOS/macOS 17.4/14.4 and newer when building a project that simply just includes the iOS 18 @AssistantIntent Macro?

The beta 4 releases still have this problem. There are no notes about this that I have seen in the beta release notes. Crash message shown in console when trying to run on 17.4, 17.5, 17.5.1, etc:

dyld[21935]: Symbol not found: _$s10AppIntents15AssistantSchemaV06IntentD0VAC0E0AAWP Referenced from: <F7A1FEF0-F3B0-379C-A914-D1FB0BA7C693> /Users/jonathan/Library/Developer/CoreSimulator/Devices/CA308F47-BCA8-4429-8599-1BB1CCEAB5B6/data/Containers/Bundle/Application/D7DC8E16-90DB-406A-A521-20F18326E4A7/IntentDemo.app/IntentDemo.debug.dylib Expected in: <88E18E38-24EC-364E-94A1-E7922AD247AF> /Library/Developer/CoreSimulator/Volumes/iOS_21F79/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 17.5.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/AppIntents.framework/AppIntents

Obviously, the new Apple Intelligence AssistantIntents only work on the 2024 OS releases. However, even when these new App Intents are marked with @available(iOS 18, macOS 15, *), the app crashes on any earlier OS version. But it runs just fine on iOS 18 and macOS 15...

I would love for me to just have done something wrong but I don’t think I have… Here is the sample project: https://github.com/JTostitos/FB14323923

Maybe it's a compiler issue thats failing to strip out the macro when building for older OS's or an Xcode issue - I have no idea. I just would like to know why its not working and how to resolve it.

Thanks in advance for anyones help...

We believe this is fixed with Xcode 16.1 beta 2 and iOS 18.1 beta 4. Please update your bug reports if that's not the case!

This is still an issue as of Xcode 16.1 Beta 1.

I went ahead and made a feedback for this as well -- FB14857535. Hoping this can be addressed before RC.

@Engineer Good morning! I am sorry for the delay in my response. I am just now seeing your message this morning, as I never got a notification of a response on this post.

I have tested this fix using 17.4, 17.5, 18.0, and 18.1. While every device can now launch the app without crashes (yay! 🎉), unfortunately, as soon as you add an iOS 18 AppIntent using the AssistantIntent to an AppShortcutsBuilder, iOS 17 can no longer launch the iOS 17 compatible AppShortcut.

Additionally, there is a regression in iOS 18.1 where the AssistantIntent shortcut no longer prompts you to enter a search term before launching the app. But on iOS 18, this works just fine.

I have updated the feedback with this same information as well as a video to show the issue.
