Build Settings----包含

编译设置 (指令集,编译目录,编译选项,部署,链接,签名,内核模块,包,版本管理,测试，搜索路径，编译语言，编译警告)

---

A--> Architectures--体系结构(指令集) 

    1:Base SDK 指的是当前编译用的SDK版本

   2:Supported Platforms--支持的平台

  3:Build Active Architecture Only:它只编译当前的architecture版本

  4:Architectures--在这个项目里你想要Xcode编译的目标设备列表

  5:Valid Architectures 该编译项指定可能支持的指令集，该列表和Architectures列表的交集，将是Xcode最终生成二进制包所支持的指令集

B-->Build Locations -- 编译目录(文件目录)

   1:Build Products Path 产品文件和编译时临时文件都将放在这个目录的子目录中

  2:Intermediate Build Files Path  编译时临时文件的存放位置。编译中间文件格式为product name+.build，如MyProduct.build。

  3:Per-configuration Build Product Path 当前编译设置下的产品存放位置

  4:Per-configuration Intermediate File Path 当前编译设置下编译时临时文件的存放位置

  5:Precompiled Headers Cache Path 存放预编译头文件的位置。通过这个配置，Targets可以互相共享预编译的头文件

C--> Build Options  -- 编译选项（编译器选择，debug文件类型，Bitcode，生成的文件类型，私有API验证）

   0:Build Variants 此项可以设定生成产品的变种

   1:Compiler for C/C++/Objective-C--->选择编译器

   2:Debug Information Format 这个选项决定了记录debug信息的文件格式

   3:Always Embed swift standard libraries 是否 总是嵌入switf标准库

  4:Enable Bitcode 启用Bitcode(一种中间代码)

  5:Enable Testbility 这是单元测试有关选项，项目里如果没有单元测试 就关了吧

  6:Generate Profiling Code 是否生成配置代码。默认选择NO。

  7:Precompiled Header Uses Files From Build Directory 未改动的文件保留成预编译文件

  8:Scan All Source Files for Includes 扫描include文件所包含的所有源文件。

  9:Validate Built Product  这个选项决定了是否在编译的时候进行验证

  10:Require Only App_Extension-Safe API APP 扩展API 的使用

D--> Deployment (部署) / signing (签名) / Linking (链接)

G--> Headers(头部) / Kernel Module (内核模块) / Packaging  (包) / Search Paths (搜索路径) / versioning  (版本控制)

Preprocessor Macros：可以这个里面定义一些预处理的宏。例如，Xcode 自动帮你在 Debug 里面定了一个宏 DEBUG=1，这样就可以用这个宏来判断当前的App是不是Debug版本了
