Hi, I usually use automatic synch to transfer music files from iTunes to iPhone. I'm currently running Beta 4 and still on latest version of Mojave. I can connect my iPhone just fine to iTunes except when the synch starts nothing transfers. It almost acts like I didn't add anything new to iTunes but that isn't the case. Do I have to upgrade to Catalina MacOS beta to work or am I doing something wrong? Thanks for your help.
 
You don’t need to upgrade to Catalina and I highly suggest you don’t do it. Catalina is a mess.

With that being said, there is a chance that your iTunes library on your iPhone is damaged, so it won’t accept any changes. You can use apps like iexplorer on your Mac to manually delete everything inside this “iTunes_Control” folder, restart your phone and try to sync again. Do make an iTunes backup before doing so.
