xcrun 命令

常用示例

说明

xcrun is macOS's command-line utility for locating and invoking developer tools from the Xcode toolchain. It serves as an intelligent wrapper that finds the correct version of tools like clang, swift, ld, and others based on the active Xcode installation and selected SDK. The tool resolves the complexity of having multiple Xcode versions or SDKs installed by automatically selecting the appropriate tool version. It respects the DEVELOPER_DIR environment variable and the setting from xcode-select, making it essential for build scripts and CI/CD pipelines that need consistent tool resolution. Beyond simple tool invocation, xcrun provides access to powerful subcommands through tools like simctl for iOS Simulator management, notarytool for app notarization, altool for App Store uploads, and stapler for attaching notarization tickets.
