- Missing packages or files mentioned
  - The Swift compiler/toolchain is missing: swift binary not found in the image.

- Version mismatch info
  - Base image used: swift:jammy-slim (Ubuntu Jammy). Despite attempting to build with Swift, the swift CLI is not present in this environment, indicating a mismatch between the base image expectations (Swift toolchain) and the actual installed tooling.

Summary (under 1500 chars):

- Failing command/step:
  - Builder step: builder 6/6
  - Command: RUN swift build -c release
  - Exit code: 1
  - Failure context: The swift build step did not complete successfully during image build.

- Exact error messages (preserved):
  - error: 'grpc-swift': package 'grpc-swift' @ 1.27.1 is using Swift tools version 6.1.0 but the installed version is 5.10.1
  - error: 'swift-log': package 'swift-log' @ 1.9.1 is using Swift tools version 6.1.0 but the installed version is 5.10.1
  - error: 'swift-nio': package 'swift-nio' @ 2.93.0 is using Swift tools version 6.0.0 but the installed version is 5.10.1

- Missing packages or files mentioned:
  - No missing files/packages; the issue is a Swift toolchain version mismatch. The packages require newer Swift tools than what is installed.

- Version mismatch information (key details):
  - Packages require newer Swift tools:
    - grpc-swift @ 1.27.1 requires Swift tools version 6.1.0
    - swift-log @ 1.9.1 requires Swift tools version 6.1.0
    - swift-nio @ 2.93.0 requires Swift tools version 6.0.0
  - Installed/available Swift tools version in the build image: 5.10.1
  - Result: Incompatibility between package tool versions and the Swift toolchain in the base image (swift:5.10).

Image swift:6 NOT found on Docker Hub.

Image swift:latest exists on Docker Hub.

- Failing command details: The error occurs during the Swift build in the Tart project inside the Docker build (Swift toolchain from swift:latest base image). The Dockerfile line is: RUN swift build -c release
- Missing packages or files: None reported; the failure is due to overlapping sources in the TartTests target, not missing files.
- Version mismatch info: No explicit version mismatch reported; base image used is swift:latest.
- Quick context: The build fetches many Swift packages, then fails at the TartTests source overlap check during the final swift build step.

- Exact error message and exit code
  - /bin/sh: 1: swift: not found
  - Exit code: 127

- Failing command/step
  - Step [5/7] RUN swift package resolve

- Missing packages or files mentioned
  - Swift toolchain binary (swift) not found in the container; the apt-get steps install other deps (git, curl, ca-certificates) but do not install Swift

- Version mismatch info
  - Base image used: docker.io/library/swift:jammy-slim@sha256:a0d255bfd43611e642fa931ec542b2ed4134caa5eeb11c5c2090ab0de9cf2353
  - Implication: the jammy-slim variant in this image does not include the Swift CLI, causing the swift package resolve command to fail with not found

Notes:
- The build attempts to resolve Swift dependencies, but the Swift toolchain is absent from the base image, leading to the error. A base image that includes Swift or an explicit Swift installation step is needed.

Tart is a virtualization toolset to build, run, and manage macOS and Linux VMs on Apple Silicon. It uses Apple’s Virtualization.Framework for near-native performance and supports pushing/pulling VMs from OCI-compatible registries, plus a Tart Packer Plugin and CI integration. It powers Cirrus Runners, a drop-in replacement for GitHub-hosted runners with 2–3× better performance.

Usage notes (macOS 13.0 Ventura+; downloads a ~25 GB image):
- Install: brew install cirruslabs/cli/tart
- Clone base image: tart clone ghcr.io/cirruslabs/macos-tahoe-base:latest tahoe-base
- Run: tart run tahoe-base

Docs:
- Official docs: tart.run
- Discussions: https://github.com/cirruslabs/tart/discussions

Key items:
- Package/name: cirruslabs/cli/tart
- OCI image: ghcr.io/cirruslabs/macos-tahoe-base:latest
- VM size/download: ~25 GB image
- Target platform: Apple Silicon macOS 13.0+

- Failing step (command): RUN swift build -c release --build-system swiftbuild --product tart
- Exact error message and exit code:
  - exit code: 1
  - error: 'workspace': product 'ResourceExtension' required by package 'workspace' target 'tart' not found in package 'opentelemetry-swift'.
- Missing packages/files mentioned:
  - ResourceExtension product missing in the opentelemetry-swift package (causing the Tart target to fail during build).
- Version mismatch info:
  - No explicit version mismatch is shown in the log; the failure indicates a packaging mismatch in opentelemetry-swift (ResourceExtension not found), which could be due to an incompatible or mismatched version of opentelemetry-swift.

- Version mismatch info:
  - None detected in the log. The log shows a missing product rather than a version mismatch. (Note: the Dockerfile notes macOS dependencies on Linux, but the error itself is a Swift package resolution/build issue.)
