xmake不只能够支持 c/c++文件，同时也支持 objc/c++，甚至swift代码的编译。c++

咱们先看一下如何建立Swift工程，首先执行--help，看下帮助文档：git

xmake create --help

显示以下：github

Usage: xmake create [options] [target]

Create a new project.

Options:
-n NAME, --name=NAME The project name.
-f FILE, --file=FILE Create a given xmake.lua file. (default: xmake.lua)
-P PROJECT, --project=PROJECT Create from the given project directory.
Search priority:
1. The Given Command Argument
2. The Envirnoment Variable: XMAKE_PROJECT_DIR
3. The Current Directory
-l LANGUAGE, --language=LANGUAGE The project language (default: c)
- c
- c++
- objc
- objc++
- swift
-t TEMPLATE, --template=TEMPLATE Select the project template id of the given language. (default: 1)
- language: c
1. The Console Program
2. The Console Program (tbox)
3. The Shared Library
4. The Shared Library (tbox)
5. The Static Library
6. The Static Library (tbox)
- language: c++
1. The Console Program

- language: objc
1. The Console Program
- language: objc++

- language: swift
1. The Console Program

-v, --verbose Print lots of verbose information.
--version Print the version number and exit.
-h, --help Print this help message and exit.

target Create the given target.
Uses the project name as target if not exists.

能够看到只要指定语言为swift，工程模板选择1，就能建立一个基于swift的控制台项目，具体操做以下：swift

xmake create -l swift -t 1 -P /tmp/test -n swift_test

执行完成后，就会在/tmp/test目录下自动生成一个名为swift_test的工程bash

咱们看下生成好的xmake.luathis

-- the debug mode
if modes("debug") then
    
    -- enable the debug symbols
    set_symbols("debug")

    -- disable optimization
    set_optimize("none")
end

-- the release mode
if modes("release") then

    -- set the symbols visibility: hidden
    set_symbols("hidden")

    -- enable fastest optimization
    set_optimize("fastest")

    -- strip all symbols
    set_strip("all")
end

-- add target
add_target("swift_test")

    -- set kind
    set_kind("binary")

    -- add files
    add_files("src/*.swift")

能够看到，和日常的xmake.lua描述没什么区别，惟一的改动就是：add_files("src/*.swift") lua

而生成的main.swift代码，也很简单：.net

import Foundation

print("hello world!")

如今咱们进入/tmp/test目录编译下：debug

cd /tmp/test
xmake

编译完后，就能够运行了：code

xmake r swift_test

显示效果：

··· hello world! ···

搞定。
