The GUID is also necessary if you want to have "as" and "is" support.
It is?
I have been using interfaces without GUID and as/is works fine.
At least as/is Tsomeclass

Right, an UUID/GUID for interfaces is Windows COM specific.
So, what is the purpose of this UUID and the method provided by
TInterfacedObject?
The GUID allows to look up the interface definition when a type

The GUID is also necessary if you want to have "as" and "is" support.
