Code coverage is not working

[AntonRomanchuk]

Problem

When I add your dependency via SPM, code coverage stops working. For clarification, I created new project with only this dependency - the same result.

My SPM package file:

// swift-tools-version: 5.7.1
import PackageDescription

let package = Package(
    name: "SomePackage",
    platforms: [
        .iOS(.v15)
    ],
    products: [
        .library(
            name: "SomePackage",
            targets: ["SomePackage"]),
    ],
    dependencies: [
        .package(url: "https://github.com/gematik/ref-OpenHealthCardKit", from: "5.3.0"),
    ],
    targets: [
        .target(
            name: "SomePackage",
            dependencies: [
                .product(name: "HealthCardControl", package: "ref-OpenHealthCardKit"),
                .product(name: "NFCCardReaderProvider", package: "ref-OpenHealthCardKit"),
                .product(name: "HealthCardAccess", package: "ref-OpenHealthCardKit"),
                .product(name: "CardReaderProviderApi", package: "ref-OpenHealthCardKit"),
                .product(name: "Helper", package: "ref-OpenHealthCardKit"),
            ],
            cSettings: [ .unsafeFlags(["-w"]) ],
            swiftSettings: [ .unsafeFlags(["-suppress-warnings"]) ]
        ),
    ]
)

Additionally, I'm getting this message for every test run on Xcode Cloud:

Failed to merge raw profiles in directory /Volumes/workspace/DerivedData/Build/ProfileData/86DCE839-AA1A-4025-97FB-6B816DCA956E to destination /Volumes/workspace/DerivedData/Build/ProfileData/86DCE839-AA1A-4025-97FB-6B816DCA956E/Coverage.profdata: Aggregation tool '/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/llvm-profdata' failed with exit code 1: warning: /Volumes/workspace/DerivedData/Build/ProfileData/86DCE839-AA1A-4025-97FB-6B816DCA956E/B70CE6AE-BC56-4151-AD4E-E887E802B1EB-3219.profraw: invalid instrumentation profile data (file header is corrupt) error: no profile can be merged

Expected Behavior

Code coverage works as before

Actual Behavior

Code coverage is not working

Steps to Reproduce the Problem

1. Add this dependency via SPM
2. Add some tests
3. Run tests and check code coverage

Specifications

• Framework version: 5.3.0
• Platform: iOS
• Xcode versions: 15+
• Subsystem: iOS 15-17

@sigabrtz any updates, plans?

@AntonRomanchuk I did some research and found the main issue being the OpenSSL wrapper. This one ist distributed with a binary, I guess that has to match at least to some extend to get the coverage working again. So if you change your dependencies to just include

.package(url: "https://github.com/gematik/OpenSSL-Swift", from: "4.1.0"),

instead of OHCKit, it will fail with the same error. We'll schedule a fresh build with Xcode 15.2 for that library. I have no permanent solution though (yet).

[sigabrtz]

@AntonRomanchuk We released a new Version 5.7.0 that depends on Swift-OpenSSL 4.2.0 (which itself contains a library built with XCode 15.2).

With that the unwanted behavior seems to be fixed.

@sigabrtz it is working again, thank you!
