slather coverage fails because of PBXGroup

[trichard-jabra]

I have a floder in Xcode (16.1) that needs to remain a folder but I get this error.
Changing it to a group fixes the error but is not a solution

I am not using Cocoapods which is why I am reporting this here

Slathering...

[authiatr]

Hello,

Slather uses the Cocoapods/XcodeProj open-source library as a sub-dependency.
Until last week release, XcodeProj didn't support Xcode 16 new attributes.

Now, we need Slather's maintainers to update this library and release a new version.

I opened a pull request #574.
Hopefully, it will be approved and merged soon.

Cheers
