Summary of Docker build error

- Exact error message and exit code
  - /bin/sh: 1: swift: not found
  - exit code: 127
  - The log shows:
    - /bin/sh: 1: swift: not found
    - process "/bin/sh -c swift package resolve" did not complete successfully: exit code: 127

- Failing command/step
  - Failing step: RUN swift package resolve
  - Dockerfile context snippet:
    - >>> RUN swift package resolve

- Missing packages or files mentioned
  - The error indicates the Swift toolchain (swift binary) is not present in the image PATH.
  - There is no Swift installation performed in the shown steps; the apt-get install sequence installs build-essential, libxml2-dev, libcurl4-openssl-dev, libssl-dev, git, ca-certificates, etc., but not Swift.
  - Implication: base image swift:jammy-slim did not provide a usable swift binary at runtime for this step.

- Version mismatch info
  - No explicit Swift version mismatch is shown in the log.
  - The root cause appears to be the absence of the Swift toolchain rather than a version negotiation issue.

Recommended fix
- Use a Swift-enabled base image or install Swift in the Dockerfile before running swift package resolve (e.g., add steps to install the Swift toolchain or switch to a base image that includes Swift).

Summary of Docker build error

- Exact error message and exit code:
  - exit code: 1
  - fatal error: 'Foundation/Foundation.h' file not found

- Missing packages or files mentioned:
  - Foundation/Foundation.h not found (Foundation framework headers missing in the Linux container)

- Version/platform mismatch info:
  - The build uses swift:jammy (Swift on Ubuntu 22.04) to compile an Apple platform target (AppAuthTV) that requires the macOS/iOS Foundation headers. The container lacks Foundation headers, indicating a platform/SDK mismatch: Apple Foundation headers are unavailable in this Linux image, so Linux-based Swift image cannot build this Apple-targeted code.

# This image is not suitable for building AppAuth-iOS / AppAuthTV on Linux.
# The repository targets Apple platforms and contains Objective-C sources that
# require Apple's Foundation headers unavailable on Linux containers.
# For building this project, use a macOS-based runner (e.g., GitHub Actions macos-latest).

- Missing packages or files mentioned
  - The tarball at the URL https://download.swift.org/swift-5.3-release-ubuntu22.04.tar.gz was not found (404), causing the curl download to fail.

- Version mismatch info
  - The Dockerfile attempts to fetch the Swift 5.3 release tarball for Ubuntu 22.04 (Jammy), but the URL responds with 404, indicating the file is not available for that OS/version in that location. This suggests a mismatch between the requested Swift 5.3 tarball and the (Jammy) base image.

- Missing packages or files mentioned:
  - Missing or misconfigured source path for the AppAuth target: invalid custom path 'Sources/AppAuth' for target 'AppAuth'
  - The build previously copied only Sources/AppAuthCore; no Sources/AppAuth directory appears to exist, leading to the invalid path error

- Version mismatch information:
  - Builder image uses swift:5.3-bionic (Swift 5.3)
  - Runtime base image uses Debian bookworm-slim
  - Error is due to source path configuration, not a direct version mismatch, but Swift 5.3 is the involved toolchain

- Context notes:
  - Prior steps completed: copying Package.swift, copying Sources/AppAuthCore, swift package resolve
  - The failure occurs at building the AppAuthCore product due to a misdefined or missing AppAuth source path referenced by the Package.swift target AppAuth

Actionable details from the Swift Package manifest:

Summary of Docker build error

- Exact error message and exit code
  - Exit code: 1
  - Error: invalid custom path 'Sources/AppAuth' for target 'AppAuth'

- Failing command/step
  - [builder 7/7] RUN swift build -c release --product AppAuthCore

- Missing packages or files mentioned
  - The Swift Package targets reference a pathSources/AppAuth for the AppAuth target, but the build context only copied Sources/AppAuthCore. The directory Sources/AppAuth is missing, causing the invalid custom path error.

- Version mismatch info
  - Base image: swift:5.3-bionic
  - Runtime image: debian:bookworm-slim
  - No explicit version mismatch reported; the failure is due to a missing source path rather than a version issue.

  - Context: The build process attempted to run swift build -c release and failed with the above error.

- Missing packages or files mentioned
  - The Swift compiler/toolchain is not present in the build image; swift binary not found in PATH.
  - Implication: Swift was expected to be available in the build stage but isn’t installed or accessible.

- Version mismatch information
  - Build stage base image appears to be swift:jammy-slim (see prior step referencing FROM docker.io/library/swift:jammy-slim).
  - Runtime stage uses a different base image (debian:bookworm-slim), indicating a mismatch between build-time and runtime environments.
  - This mismatch could contribute to Swift not being available in the build context if the Swift toolchain isn’t installed in the specific build stage.

Image swift:5.3 exists on Docker Hub.

- Missing packages or files mentioned
  - The Swift compiler binary is not present in the image; “swift” command not found implies the Swift toolchain is not installed in the base image (base image is swift:jammy-slim).

- Version mismatch info
  - Base image used: docker.io/library/swift:jammy-slim. This image apparently does not include the Swift compiler needed to run swift build, indicating a mismatch between the build requirement (Swift toolchain) and the image content.

Summary (under 1500 chars):

- Exact error message and exit code:
  - "'AppAuth' /app: error: target at '/app/UnitTests' contains mixed language source files; feature not supported"
  - Exit code: 1

- Failing command/step:
  - [build  7/10] RUN swift build -c release
  - After this step, the process exited with code 1:
    - ERROR: process "/bin/sh -c swift build -c release" did not complete successfully: exit code: 1

- Missing packages or files mentioned:
  - Warning indicates an unhandled file: "warning: found 1 file(s) which are unhandled; explicitly declare them as resources or exclude from the target"
  - Affected file: /app/UnitTests/UnitTestsInfo.plist
  - There are no explicit missing packages; the failure is due to mixed-language sources in the UnitTests target.

- Version mismatch info:
  - Base image: swift:5.3-bionic (Dockerfile shows using Swift 5.3 on Ubuntu Bionic)
  - No explicit version mismatch reported; failure caused by the Swift compiler refusing mixed-language sources in /app/UnitTests.

- Exact error message and exit code
  - Exit code: 1
  - Error: 'AppAuth' /app: error: invalid custom path 'UnitTests' for target 'AppAuthCoreTests'

- Failing command/step
  - [build 6/8] RUN swift build -c release (Dockerfile:18)

- Missing packages or files mentioned
  - No missing packages/files reported. The issue is a misconfiguration: invalid custom path 'UnitTests' for target 'AppAuthCoreTests' (likely a Swift Package target path problem).

- Version mismatch info
  - Base images involved: swift:5.3-bionic and debian:bookworm-slim
  - No explicit version mismatch reported in the error; the failure is due to the Swift package target path.

This directory contains test cases for AppAuthCore and AppAuthTV. Some tests may rely on macOS-only frameworks and are not suitable for Linux builds.

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

Failing command/step:
- [build 6/8] RUN swift build -c release

Missing packages or files mentioned:
- Swift toolchain (swift binary) not found in the image
- Base image: swift:jammy-slim@sha256:a0d255bfd43611e642fa931ec542b2ed4134caa5eeb11c5c2090ab0de9cf2353

Version mismatch info:
- The Dockerfile uses a Swift base image (jammy-slim) with a specific digest, but the swift compiler is not present in this build stage, indicating a mismatch between the base image contents and the required Swift toolchain.

Notes:
- Failure occurs during the library build step after copying Package.swift and Sources.
- Suggested fixes: install the Swift toolchain in the build image or use a Swift-enabled base image that includes the swift binary; ensure PATH includes swift.

  - Error: 'AppAuth' /app: error: invalid custom path 'UnitTests' for target 'AppAuthCoreTests'

- Failing command/step
  - [build 7/9] RUN swift build -c release

- Missing packages or files mentioned
  - No missing packages were reported. The error indicates an invalid custom path for a test target (path 'UnitTests' for target 'AppAuthCoreTests'), suggesting a misconfigured or non-existent path in Package.swift.

- Version mismatch info
  - Base image used: swift:5.3-bionic (Debian bookworm-slim). No explicit version mismatch error; the failure appears to be a Swift Package Manager configuration issue rather than a version compatibility problem.

- Exact error message and exit code:
  - "'AppAuth' /app: error: invalid custom path 'UnitTests' for target 'AppAuthCoreTests'"
  - Exit code: 1

- Failing command/step:
  - Build step: [build 6/8] RUN swift build -c release

- Missing packages or files mentioned:
  - None. The error is due to an invalid custom path in the Swift Package target, not a missing package or file.

- Version mismatch info:
  - Build uses Swift image swift:5.3-bionic (Swift 5.3) and Debian base image for runtime debian:bookworm-slim. The failure occurs during the Swift build step, but there is no explicit version mismatch noted beyond the images in use.

Notes:
- The error indicates a misconfiguration: a custom path "UnitTests" specified for the target AppAuthCoreTests is not valid. Check Package.swift (or the SwiftPM target configuration) to ensure test targets reference proper directories.
