Persistent cloud anchors ios xcode crash when trying to host

[michelepanegrossi]

I get an app crash when clicking on the begin hosting button in the Persistent Cloud anchors sample. I am running version 1.34.0, ARFoundation 4.2.7.

I am running on unity 2021.3.15f and Xcode 14.1. I am going to try unity 2019.

Any idea what could be wrong?

This is the stack from Xcode

The solution was to download the external dependency manager unity package from this link. When importing, it will throw an error in the console saying that there is a conflict with the dependency manager which is included in the extensions package.

To remove it, go into packages -> ARCore Extensions -> Editor, right click on 'reveal in finder' and manually delete the folder called 'ExternalDependencyManager'. Unity will recreate the folder immediately but it will be empty and the issue should be solved. It worked for me.
