AMPathPopUpButton and AMTokenField

Among Xcode standard components there's AMPathPopUpButton and AMTokenField.

We get error when we want to bind reference of them to our view controller.

Error saying:

Use of undeclared type 'AMPathPopUpButton'

Use of undeclared type 'AMTokenField'


Automator is imported

In which framework they are defined ?


Could anyone provide hints or documentation how to use them ?
