如何在 Swift 脚本中运行终端命令?(例如 xcodebuild)

问题描述：

我想用 swift 替换我的 CI bash 脚本.我不知道如何调用普通的终端命令，例如 ls 或 xcodebuild

I want to replace my CI bash scripts with swift. I can't figure out how to invoke normal terminal command such as ls or xcodebuild

#!/usr/bin/env xcrun swift

import Foundation // Works
println("Test") // Works
ls // Fails
xcodebuild -workspace myApp.xcworkspace // Fails

$ ./script.swift
./script.swift:5:1: error: use of unresolved identifier 'ls'
ls // Fails
^
... etc ....

答

如果您不在 Swift 代码中使用命令输出，以下就足够了:

If you don't use command outputs in Swift code, following would be sufficient:

#!/usr/bin/env swift

import Foundation

@discardableResult
func shell(_ args: String...) -> Int32 {
    let task = Process()
    task.launchPath = "/usr/bin/env"
    task.arguments = args
    task.launch()
    task.waitUntilExit()
    return task.terminationStatus
}

shell("ls")
shell("xcodebuild", "-workspace", "myApp.xcworkspace")
