❕ Problem Statement

Xcode 12 is about to be released and compiler is building for the upcoming arm64 architecture. When having command line tools set to Xcode 12 and running carthage build [--no-skip-current], the build fails with:

error: The linked library 'libpact_mock_server.a' is missing one or more architectures required by this target: arm64. (in target 'PactSwift_macOS' from project 'PactSwift')

💬 Task Description

Build new libpact_mock_server.a static libs that include arm64 architecture.

This is likely going to be difficult to solve until Carthage adds XCFrameworks support. See Carthage/Carthage#3019 for more details.

Correct. If anyone notices it being sorted out, a PR is welcome. I will commit a script/documentation that will run cargo build commands and replace the existing binaries.

On top of that, having these binaries wrapped in a XCFramework might be a better idea altogether.

Got fed up with waiting for Carthage and used @rastersize provided bash script to test with Xcode 12.2.
Script added to PactSwift with commit 473f298.
