Key Paths

class KeyPath

A key path from a specific root type to a specific resulting value type.

class AnyKeyPath

A type-erased key path, from any root type to any resulting value type. NOTE: older runtimes had Swift.AnyKeyPath as the ObjC name. The two must coexist, so it was renamed. The old name must not be used in the new runtime. _TtCs11_AnyKeyPath is the mangled name for Swift._AnyKeyPath.
