Cannot Forward Declare for a TSubClassOf or for a UPROPERTY() Member. How Can I Have Co-Dependency?

[Jambax]

I’ve run into this quite often.

Although it seems counter-intuitive, I’ve found the forward declaration often works when including the SubclassOf.h header. Still not certain as to why.

#include "Templates/SubclassOf.h"

class USomeType;

You may know already, but if not - you can only forward-declare pointers to types.
