Archive Fails When Building XCFramework from Swift Package when using swift-async-algorithms

[KrishnaKishore1992]

We have a Swift package that consumes the swift-async-algorithms package, and it works as expected in Xcode. We are trying to generate an XCFramework(Swift Package) for Objective-C bridging. While the build process in Xcode works without issues, the archive process via xcodebuild fails with multiple errors.

Steps to Reproduce:

1. Create a Swift package that depends on swift-async-algorithms.
2. Open the package in Xcode and verify that it builds successfully.
3. Run the following xcodebuild command to archive and create an XCFramework:

xcodebuild -project "Library.xcodeproj" archive \ -scheme "Library" \ -configuration Release \ -archivePath "build/Library-ios.xcarchive" \ -destination "generic/platform=iOS" \ -derivedDataPath "build" \ -IDECustomBuildProductsPath="" \ -IDECustomBuildIntermediatesPath="" \ ENABLE_BITCODE=NO \ SKIP_INSTALL=NO \ BUILD_LIBRARY_FOR_DISTRIBUTION=YES

4. Observe the errors during the xcodebuild archive step.

Expected Behavior:

The Swift package should be successfully archived, allowing us to generate the XCFramework for use in Objective-C projects.

Actual Behavior:

The following errors occur during the archive step:

Environment:
Xcode version: 26.x
Swift version: 5, 6
Platform(s): iOS
swift-async-algorithms version: latest
Additional Context:
We need to archive this package into an XCFramework for Objective-C bridging. The issue only occurs during the archive step and not during the build process within Xcode.

Can you please help us ASAP. 😊

Thanks in advance.
