Package product cannot be used because of unsafe build flags

[Bart]

Hello.

When running the test that's using SBTUITestTunnel I'm getting the error:

error: The package product 'SBTUITestTunnelClient' cannot be used as a dependency of this target because it uses unsafe build flags. (in target 'UITests' from project 'XXX')

Is it something that you can fix on your side?

I'm using SPM and this version 👇

I build the project with Xcode 13.3.1
I tried cleaning the derived data and build folders but that didn't help.
