product name; example
org name: cyper
org id: me.cyper
bundle id: me.cyper.example
保存在桌面.
example > example.xcodeproj
example > example/main.swift
选择products>example，右边identity and type,type选择Unix-Executable可以看到生成的可执行文件的全路径
/Users/cyper/Library/Developer/Xcode/DerivedData/example-ajcwintjwwixdreqjjijwrzqriom/Build/Products/Debug/example
这个hello world文件大约5M
