First class name does not exist in autocomplete field in Xcode 7.3

Question

When I write presentViewController code, the first class name of the class does not appear in the autocomplete field. So whenever I want to use presentViewController, I copy the class name.

Here is a screenshot

I already declared a login class, but it does not appear in autocomplete.

I think you need to create an Xcode project after creating a new class, file, variable that you want to import into another class.
