Looking for learning resources for MacOS development

Hi all, I've been looking around at a few courses for MacOS app development using Swift, but a lot of the courses seem to be a couple of years old at this point, with the majority of Swift content about iOS development.

I have experience with other languages and with Swift on iOS, and so a lot of the content aimed at beginners doesn't get as advanced as I would hope, or as said is quite dated.

I was hoping there would be an IH out there with a book or course out there to get me started, keep the money within the family.

Please let me know if you have anything out there, or if you were in my position once before stumbling on some good resources!
