No type or protocol named wkextensiondelegate

Question

I am going to upgrade my existing project from iOS 7.0 to 9.1 with the extension of the application for viewing through File → New → Target → Application for viewing the clock.

he will add the application extension for viewing in the main package with some files and a storyboard for viewing.

My problem is that when I run the application for viewing, it gives me an error "No type or protocol named wkextensiondelegate"

see in my screenshot

I added watchkit.framework for the project -> Target -> build phase -> Binary link with libraries.

Thanks in advance.
