After downloading the sea creator project, found here:
https://developer.apple.com/documentation/safariservices/safari_web_extensions/developing_a_safari_web_extension

Opening it in XCode immediately crashes XCode itself. Running XCode Version 12.0 beta 5 on mac catalina 10.15.6.

This is the error log I'm getting:

Just open a Terminal.app and type the following command:

Code Block xattr -rc /path/to/your_project_directory

then press "Enter" and voila!

The crash caused by the fact that the project has been downloaded from the Internet, so Xcode should request permission to open it, but it can't handle the situation correctly.

Xcode 12 GM has been released, do you see that crash with the final version?

I am experiencing this with Xcode 12.0.1. The workaround with xattr -rc does not work for me.

I can confirm I downloaded and unzipped this project from the internet (gitlab). The crash is immediate upon opening that version.
