Could you bump the minor version from Zip in its podspec (2.1.3) file like in this PR, please? 🙇 https://github.com/marmelroy/Zip/commit/67fa55813b9e7b3b9acee9c0ae501def28746d76

Also, I think this also has to be added to the podspec (example):

s.resource_bundles = {
    "#{s.module_name}_Privacy" => 'Zip/PrivacyInfo.xcprivacy'
}
