ios - What is the swift equivalent to _cmd?

Question

asked Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

I want to get current method name to use in a format message similar to this one

[NSExeception raise:NSInternalInconsistencyException format:@"You must override %@ in a subclass", NSStringFromSelector(_cmd)]

Also, I want to use _cmd to set associated object. I appreciate any idea.
