The protocol to which all types implicitly conform

The protocol to which all class types implicitly conform.

When used as a concrete type, all known @objc class methods and properties are available, as implicitly-unwrapped-optional methods and properties respectively, on each instance of AnyClass. For example:

class C {
  @objc class var cValue: Int { return 42 }
}
 
// If x has an @objc cValue: Int, return its value.  
// Otherwise, return nil.
func getCValue(x: AnyClass) -> Int? {
  return **x.cValue**
}
