attribute 'srcs' in 'filegroup' rule: invalid target name '_:).json':

I see the issue. One of the filenames in this directory is !=(_:_:).json. Bazel is choking on that combination of characters as a valid target name.

The rules_spm project is lightly deprecated. There are some limitations with its design. However, I am actively working on swift_bazel. It is designed to replace rules_spm and provide other niceties like a Swift Gazelle extension. I would recommend trying swift_bazel to bring in those external Swift packages.

(The file should not be a problem if you use swift_bazel. The Swift package manifest does not reference the file. So, it should not appear in any of the Bazel build files that are generated.)

Ah okay! I made it further with swift_bazel, but I encountered this new error when trying to archive the app for the App Store:
cgrindel/rules_swift_package_manager#182
I went into more detail here:
bazelbuild/rules_apple#1814
Because I wasn't sure which side this issue was on (rules_apple or swift_bazel)
