解决方法参考：

/ When the `accessibility inspector' is enabled on the iOS Simulator the private `UIAccessibility'
// framework is loaded. In turn it will try to load a list of bundles amongst which is one that has
// only resources, no executable. This leads to `CFBundleLoadExecutableAndReturnError' logging this
// offending error message.

accessibility inspector 可用的时候，ios 模拟器会调用私有api：UIAccessibility，这个时候模拟器回去加载一个不可执行的资源，爆出CFBundleLoadExecutableAndReturnError 异常并打印

比较方便的解决方法是：

1. 还原模拟器的设置

2. 如果第一步不行，在mac系统里面新建一个用户，在新用户下不会报错

3. 使用 https://gist.github.com/alloy/9277316 的代码解决方案
