Using SPM, updated from 5.1.0 -> 5.8.0, 'PubNub/PubNub+Core.h' file not found

[oronbz]

Hi,
After updating this package through SPM from 5.1.0 to 5.8.0,
I'm getting errors while building this package:
'PubNub/PubNub+Core.h' file not found all over the place:

Xcode 16.4.

Tried cleaning, deleting derived data, closing and reopening Xcode, none of this work but reverting to 5.1.0.

Please assist.

Edit: I've just tried to update incrementally to every version and discovered that it's happening since 5.6.0
