Xcode 26.1 Package Resolve Issue

Summary: Xcode 26.1 Package Resolve Issue

  • Problem: In Xcode 26.1, opening certain Swift packages (Home and Root) hangs indefinitely at Package Resolution.

  • Reproduction:

    • Works fine in Xcode 16.4.

    • In Xcode 26.1, all other 40+ packages in the same workspace resolve and build normally.

    • The main project itself also builds and runs without issues.

  • Scope: Only affects the aggregator/root packages (Home and Root) in the workspace.

  • Symptoms:

    • Xcode gets stuck during the package resolution step.

    • CLI commands like swift package resolve also hang for these packages.

  • Impact: Blocks opening the package independently in Xcode 26.1, though main project and other packages are unaffected.

Thanks for the information. If possible, could you create a GitHub issue against Swift-package-manager repository and provide a minimal reproducible case?
