doctor

Inspects the local toolchain and reports what’s installed, what’s missing, and where each tool was found.

Synopsis

swiftspawn doctor

Description

Run doctor after installing swiftspawn to confirm the environment is ready, or any time builds start failing for environmental reasons. It checks for:

• macOS version
• Swift toolchain (swift --version)
• Xcode (xcode-select -p, xcodebuild -version)
• SwiftLint (swiftlint version)
• SwiftFormat (swiftformat --version)

Each tool prints version + path on success, or a hint on failure. Exit is 0 if all required tools are present.

SwiftLint and SwiftFormat are optional; missing them is a warning, not an error.

Examples

swiftspawn doctor

Sample output:

macOS:        26.0
