Ok, after 3 weeks suffering with those issues I can say that:
Don´t use xcode 10.1 (or 10.0), use xcode Version 9.4.1.
Use unity 2017.4.16f1 (not 2018 in any version, I tryed all until February 2019)
Use easyar 2.3.0
You have until march 2019 to upload with those tips, and now (inmediatly) move everything you made on easyAR to vuforia. Simple.
