I moved all of my snapshot dependencies and some utility code that simplified my testing to a separate Package, so I didn't need to import all of my snapshots dependencies in every Package I wanted to use snapshot testing. The importing Package and the Snapshots Packages are both Local Swift Packages.

I am getting the following error while trying to run Previews:

XCPreviewAgent crashed because "Testing.framework" is missing

• The Package builds
• The Previews work when I remove the imported Package

The Package I'm importing relies on which in turn relies on swift-snapshot-testing

It turns out that the PreviewSnapshotsTesting part relies on Testing.framework and this clashes with a non-testing target that Previews require. I split up my Snapshots Package in two targets, one to be imported by the target that does Previews, the other one by the test target.

Everything works again.
