SwiftGen "Killed: 9" at startup because "Code Signature Invalid", but only if installed via Homebrew

Question

I installed the latest (6.4.0, October 2020) version of SwiftGen via Homebrew on a new MacBook Pro M1 running Big Sur (11.1), but every time I try to run it, it's killed, and the console says that it's because EXC_BAD_ACCESS (Code Signature Invalid).

The 6.4.0 binary downloaded straight from the GitHub release page works. This sounds like there's a problem with the Homebrew version.

• Who is responsible for fixing the Homebrew version?

• I can replace the Homebred-installed one (at /usr/bin/local/swiftgen) with the downloaded binary, but the download also contains a number of frameworks and stencils. Where those should be copied to?

The relevant console bits are:

Answer 1

I solved the second part of my question. The unzipped files need to be copied to /usr/local/Cellar/swiftgen/6.4.0.
