Not quite sure, but I think it's a duplicate of #44577.

You can export Mono project for iOS from macOS only. AOT compiler is macOS app. And exported project build require Xcode.

I don't know how it behaves when attempting to export to iOS for a non-Mono build from Windows/Linux, but there's no reason for Mono to behave differently here, cross platform export to iOS is impossible regardless of the Godot flavour.

Non-Mono project can be partially exported, it will export Xcode project but won't build in and create .ipa. Not sure how useful it is, since it's necessary to move in to mac to finish the build anyway.

Is it possible to export a full Xcode project when trying to export a C# project from Windows to iOS?

Even if it can't export, does it make the error message a little clearer? The error message now is "Cannot find mono runtime executeable xxx". A better way to prompt is "Go to macOS to export for iOS", or it can directly display a red text prompt "Only macOS platform can export for iOS" in the export window interface
