屏蔽掉

应该增加#if !targetEnvironment(simulator)判断。真机运行是没问题的。

原话：This happened before and is related to how obj-c symbols are imported in Swift, not deprecation/removal of API. corners at least exists in the non-simulator SDK, so you can perhaps work-around using #if !targetEnvironment(simulator).

有道理，针对模拟器屏蔽掉

看不到图片，直接针对模拟器处理代码就好，然后编辑就不会报错了
