I am developing the main app and a library (open source, forked but will go back into main repository) used by the app at the same time. I want to use Swift Package Manager and Xcode at the same time. What is the best setup in order to use the best of both worlds? Can I develop both in one workspace?

With the answer below of Alain Stulz could I make it like this: Please note that the visuals only happen after Xcode restart. Thanks, Alain!
I'll describe the approach I've used before. I'm assuming you have the Swift Package available as source code in a folder, e.g. cloned using Git.
This will resolve and fetch all dependencies and still allow you to change source code in the library on the fly if you need to.
