Bug ios AR build failed

Hi, I'm an absolute beginner to unity and I'm trying to follow one of those beginner Unity AR tutorials online. I think I got the player setting correct and I imported all required packages but my build keeps failing and only creates an empty folder with nothing in it. It's been very frustrating. Any ideas on how to debug this? Thanks a bunch!
Below is one (the longest) of the three error messages, I honestly have no idea what it means... Help is greatly appreciated!!
