Swift----安装，简介

安装：

目前最新的稳定版是 Swift 0.94.1

1.下载：wget http://swiftlang.org/packages/swift-0.94.1.tar.gz

2.解压：tar xfz swift-0.94.1.tar.gz

3.添加到PATH：export PATH=$PATH:~/swift-0.94.1/bin

4.动行swift

cd swift-0.94.1/examples/swift hello.swift

我是这样做的，似乎文档过时了:bin/swift examples/swift/tutorial/hello.swift

结果所示：

Swift 0.94.1 swift-r7114 cog-r3803 

RunID: 20140603-1042-s00t01r6 

Progress: time: Tue, 03 Jun 2014 10:42:05 +0800 

Final status: Tue, 03 Jun 2014 10:42:05 +0800 Finished successfully:1

5.测试一下：看看hello.swift

type messagefile; 

app (messagefile t) greeting() {  echo "Hello, world!" stdout=@filename(t);  }  messagefile outfile <"hello.txt">;  outfile = greeting();
