error: fatalError

In Package.swift

let swiftToolchainPath = Context.environment["OPENGRAPH_SWIFT_TOOLCHAIN_PATH"] ?? (development ? "/Volumes/BuildMachine/swift-project" : "")
if !swiftToolchainPath.isEmpty {
    sharedCSettings.append(
        .unsafeFlags(
            [
                "-static",
                "-DCOMPILED_WITH_SWIFT",
                "-DPURE_BRIDGING_MODE",
                "-UIBOutlet", "-UIBAction", "-UIBInspectable",
                "-I\(swiftToolchainPath)/swift/include",
                "-I\(swiftToolchainPath)/swift/stdlib/public/SwiftShims",
                "-I\(swiftToolchainPath)/llvm-project/llvm/include",
                "-I\(swiftToolchainPath)/llvm-project/clang/include",
                "-I\(swiftToolchainPath)/build/Default/swift/include",
                "-I\(swiftToolchainPath)/build/Default/llvm/include",
                "-I\(swiftToolchainPath)/build/Default/llvm/tools/clang/include",
                "-DLLVM_DISABLE_ABI_BREAKING_CHECKS_ENFORCING", // Required to fix LLVM link issue
            ]
        )
    )
}

After remove "-UIBOutlet", "-UIBAction", "-UIBInspectable", it works well.
table_test_case.mm -> XCTest.h → XCUIAutomation.h → AppKit.h → NSResponder.h -> IBAction.
I haven't got around to fixing this part yet.
