Citing Pwn20wnd's announcement on Twitter, unc0ver v3.0.0 beta 44 was released to add partial support for A12-A12X Bionic devices like the iPhone XS, iPhone XR, and the 2018 iPad Pro. The partial support means that you can use the latest version of Unc0ver to jailbreak your iPhone XS or iPhone XR, but you can't do anything else.
