Did you export a project with a Mono-enabled editor?

Also, can you reproduce this on 3.3.2 or 3.4beta2?

Beta 2 works, (besides other unrelated errors)
I Export from the Official Godot 3.4 Beta 3, I don't think I understand the editor question.

Godot has non-Mono and Mono editor builds. Non-Mono builds can only use GDScript and GDNative, whereas Mono builds can use GDScript, C# and GDNative.

If your project doesn't use any C# scripts, you should use a non-Mono build.

Sorry for not being clear. It's the mono build, I use only c# scripts.
(I am trying to get on the beta, because of linker errors in the stable 3.3 that creates crashes on Ad Hoc IOS builds)

It seems to happen for both MsBuild and Dotnet cli
The exports are unusually fast (compared to 3.3 stable and 3.4 beta 2) , maybe indicating that something is not being built/exported?

[EDIT] , yes it seems the
libmono-icall-table.xcframework
libmono-native.xcframework
*.xcframework

are missing in the export folder

[Difference]

Additional information:
in 3.4 beta 3 mono :
When I choose the build method, I do not see the names of the build tools, I see numbers. (see image)
By trial and error I found that
0 is MsBuild
3 is dotnet cli

I also uninstalled all dotnet sdk's and installed only 5.0.
Dotnet still build and run my Godot projects from the editor in editor, but exports are missing the *.xcframework files.

This happens when editor can't load core mono libs (nothing Mono related will work in this case), what's in the editor logs (it should have errors on editor startup).

Ok, but all the c# scripts compile and run fine from the editor, so some parts are working.
[EDIT] Also same setup works with with 3.4 beta 2, is there a config file I can edit/delete?

[bruvzg]

Ok, but all the c# scripts compile and run fine from the editor, so some parts are working.

That's strange, maybe it's only Mono editor plugin fails.

Editor config is in ~/Library/Application Support/Godot/editor-settings-3.tres, also try removing .import and .mono hidden folder from your project, maybe something from the previous beta is causing issues.

Mono logs are in ~/Library/Application Support/Godot/mono/mono_logs, and try running editor from the terminal, instead of using .app (./Godot.app/Contents/MacOS/Godot --path path_to_your_project --editor) it might print something useful.

3.4 beta 3 seems to be running fine on my M1 MacBook Air.

Export and run and device from Xcode too?

[Edit] deleting .mono and .import folders did not change anything , and I don't get errors on startup from console

Export and run and device from Xcode too?

I have tested, with official beta 3 editor and templates:

• Exporting project with C# scripts (I have .NET 6.0.100-preview.5.21302.13 installed and "dotnet CLI" selected in the Godot editor).
• Building for the iOS device. I don't to have any device on hand to test if it's running.
• Building and running iOS app on macOS.

All frameworks seem to be in place.

You obviously get the missing frameworks such as lib-aot-MonoTest.xcframework.

I uninstalled mono and then reinstalled it , but the editor still shows numbers, not names, and export does not include the frameworks ( except the project framework), so I'm unsure of what to try next.

Run the Godot editor from the terminal:

... and try running editor from the terminal, instead of using .app (./Godot.app/Contents/MacOS/Godot --path path_to_your_project --editor) it might print something useful.

Export the game and once it's finished, copy and paste the full terminal output here.

Solved! Thank you very much for guiding me to diagnosing the problem.

The log showed problems with creating directories, so thinking it was a file access problem, I deleted Godot, downloaded again, and got a prompt when starting it to open it even though it was downloaded. Export now works fine.

The problems with the Ad Hoc IOS builds, has not gone away. As far as I can tell, my problem lies with using signals with parameters, but I need to do some more testing.
Stable 3.3 Ad Hoc builds has a bug, that crashes IOS when using certain c# features (Random async etc. ) but Signals (without parameters) was ok. I will dig up the relevant bug report, but I am unsure of witch one I shall pick:

[EDIT] Hunted the Ad Hoc bug down, and made a new bug report here: #51838

In the Xcode project, I notice some files marked in red, it this important?
App runs on device, but crashes in Ad Hoc mode

How was this solved?

How was this solved?

As described above in #51526 (comment)
I don't know what went wrong with the initial install.
btw: I still have other Ad Hoc build issues, besides ToString(), but I have not found the exact cause yet.
