The Project perfectly compiles in Xcode 11 with device, when I try to compile it in Xcode 11 Simulator, it throws an error "Cannot find interface declaration for '', superclass of '' in "ProductName-Swift.h".

Issue resolved by manually merging simulator and device header files.

It cannot find Cell class.

Could you show how and where you declared it ?

Are you sure you subclass Cell and not HeaderCell ? In your SWIFT_CLASS declaration, you seem to reference HeaderCell.
