While generating format html with the current latest version getting Illegal instruction: 4.

Using latest Xcode Version 12.0.1 (12A7300)
swift-doc version: 1.0.0-beta.5

this is my command:
swift-doc generate somePath --module-name testing --output public --format html

Error:
Fatal error: could not load resource bundle: /usr/local/bin/swift-doc_swift-doc.bundle: file swift_doc/resource_bundle_accessor.swift, line 7
Illegal instruction: 4

Let me know if I am missing something.
