Sounds serious 🤔

I'm not sure if it's related, but I'm seeing a Swift compiler crash when including some dependencies via SPM.

Assertion failed: ((callerSerializedKind == IsNotSerialized || F->hasValidLinkageForFragileRef(callerSerializedKind) || hasSharedVisibility(linkage) || F->isExternForwardDeclaration()) && "called function has wrong linkage for serialized function"), function maybeAddFunctionToWorklist at Linker.cpp:108.

(to display assertion configuration options: -Xllvm -assert-help)

Thanks for posting this. I already encountered it 🙂 Now to figure out how to downgrade

[blakelee]

1. Download from here
2. Move to wherever you want (e.g. /Applications/Xcode18.2.app)
3. Run sudo xcode-select -s <wherever you put it>
4. Have KMP work again for iOS

please use https://www.xcodes.app/ to download xcodes versions
