External macro implementation type 'StructuredQueriesMacros.TableMacro' could not be found

I keep seeing this error:

External macro implementation type 'StructuredQueriesMacros.TableMacro' could not be found for macro 'Table(_:schema:)'; No such file or directory

I already enabled the macros in the issues tab. What could be cause this?

Hi @adamcircle, typically this happens when you don't enable macros "fast" enough, and for whatever reason Xcode gets stuck thinking that it doesn't have access to the macros. I'm guessing the code still compiles right? Even though it is displaying these "errors".

Eventually they go away, or you can try clearing derived data.

Another reason this may happen is if you added custom build configurations to your project beyond the default DEBUG and RELEASE. There's seems to be a bug in Xcode that shows these phantom errors in that situation, and so you may have to revert back to just DEBUG and RELEASE.

Thanks Brandon. I couldn't figure it out and ended up just uninstalling Sharing completely. I had not added custom build configs.

It really has nothing to do with this library. It’s just swift macros and Xcode in general. You can also share a minimal project that reproduces the problem if you want us to take a look.
