Can't figure out why I am getting "Class has no initializers"

Question

I am working on swift2.2 with Xcode 7.3.1 and I have a class in which I am getting the error that "Class has no initializers". After so much googling, I can't figure out that why is it happening?

I am using tableview in my view controller and a searchbar which is added in tableview and other than that I am using all those normal classes and tableview extension.

Any help would be much appreciable.

Thanks

var searchBarActive: Bool

You have to explicit searchBarActive declaration:

var searchBarActive: Bool?
var searchBarActive: Bool!
var searchBarActive = false
