my macos CI builds recently started failing with the following error message:
/Users/runner/work/png/png: error: manifest parse error(s): <unknown>:0: error: invalid Darwin version number: macos11.0 <unknown>:0: error: invalid version number in '-target x86_64-apple-macos11.0' /Applications/Xcode_12_beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.0.sdk/System/Library/Frameworks/Combine.framework/Modules/Combine.swiftmodule/x86_64-apple-macos.swiftinterface:1:1: error: failed to build module 'Combine' from its module interface; the compiler that produced it, 'Apple Swift version 5.3 (swiftlang-1184.108.40.206 clang-1220.127.116.11)', may have used features that aren't supported by this compiler, 'Apple Swift version 5.3-dev (LLVM 84c026a1b9, Swift 6bda828a7e)' // swift-interface-format-version: 1.0 ^ <unknown>:0: error: invalid Darwin version number: macos11.0 <unknown>:0: error: invalid version number in '-target x86_64-apple-macos11.0' /Users/runner/work/png/png/Package.swift:2:8: error: failed to build module 'PackageDescription' from its module interface; it may have been damaged or it may have triggered a bug in the Swift compiler when it was produced import PackageDescription ^ ##[error]Process completed with exit code 1.
i already tried reverting my
swiftenv version to
DEVELOPMENT-SNAPSHOT-2020-05-26-a (which was the last one that was working), as well as resetting
// swift-tools-version:5.2 but the builds are still failing on macos. (the linux builds are fine.)
anyone know what’s going on here?
the github action looks like this:
build-macos: runs-on: macos-latest steps: - uses: actions/checkout@v2 - uses: YOCKOW/Action-setup-swift@master ...
