'Project Name' was compiled with optimization

今天调试的时候发现变量都不能查看了。在「lldb」中通过「po」命令来查看总是提示变量未找到。

环境

xcode 7, Swift 2

错误提示

‘XXXX’ was compiled with optimization - stepping may behave oddly; variables may not be available

分析

工程在编译之后被优化了，所以导致单步的时候程序表现异常，变量也都不能访问了。这是由于编译的时候选择的是 release，而 release 的时候是会做很多优化，导致上述结果。
