The repository '@zlib' could not be resolved and referenced by '@com_google_protobuf//:protobuf'

Description of the problem:

Context: https://github.com/material-foundation/material-text-accessibility-ios/pull/28/files

I am attempting to build an iOS repository with a mixture of Swift and Objective-C libraries. It seems to break when I try to build a swift_library, while objc_library targets seem to build fine.

Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

git clone https://github.com/jverkoey/material-text-accessibility-ios.git
cd material-text-accessibility-ios
git checkout upgrade
bazel test //... --apple_platform_type=ios --ios_minimum_os=9.0

# Output:
INFO: Writing tracer profile to '/private/var/tmp/_bazel_featherless/47449ac432b212324a64889579370bdd/command.profile.gz'

Note that the following does succeed:

bazel build //:MDFTextAccessibility --apple_platform_type=ios --ios_minimum_os=9.0

But the following fails:

bazel build //:UnitTestsSwiftLib --apple_platform_type=ios --ios_minimum_os=9.0

This is an infrastructure issue and we're working on it. It should only affect Googlers and Bazel's CI.
