- Update DEVELOPER_DIR environment variable to Xcode 16.4
- Update xcode-select commands to use Xcode 16.4
- Keep using macos-15 runner which should have Xcode 16.4 available
- Changed swift.yml, rust.yml, and node.yml from direct triggers to workflow_call
- This fixes the workflow configuration error causing immediate CI failures
- Reusable workflows must use workflow_call when invoked by other workflows
- Use explicit Xcode 16.3 instead of generic Xcode.app
- Add timeouts to build steps (30 min for builds, 20 min for tests)
- Update both DEVELOPER_DIR env var and xcode-select paths
The hanging was likely due to using the default Xcode 16.0 on macOS-15
which may have compatibility issues with the project.
