Returns the class definition of a specified class.


func objc_getRequiredClass(_ name: UnsafePointer<Int8>) -> AnyClass



The name of the class to look up.

Return Value

The Class object for the named class.


This function is the same as objc_getClass(_:), but kills the process if the class is not found.

This function is used by ZeroLink, where failing to find a class would be a compile-time link error without ZeroLink.
