I had hopes that Xcode 12 will solve my SwiftUI Preview issues, but no..:(

I have a project where I can't see any previews.

What can be the problem?

I'm getting this error:

SchemeBuildError: Failed to build the scheme "NewWidgetExtension"

linker command failed with exit code 1 (use -v to see invocation)

Merge swiftmodule (x86_64):

Command MergeSwiftModule failed with a nonzero exit code

Merge swiftmodule (i386):

Merge swiftmodule (arm64):

Actually yes! But now I have a new problem - a timeout.

TimeoutError: Timed out waiting for a thunk to build after 30.0 seconds.
